"The Code Llama models provide stable generations with up to 100,000 tokens of context. 0: Note: Currently only LLaMA, MPT and Falcon models support the context_length parameter. The native context length for Llama 1 and 2 are 2,024 and 4,096 tokens. With MPT-7B-StoryWriter-65k+, MosaicML also releases a model that is able to read and write stories with very long context lengths. I checked out the blog Extending Context is Hard | kaiokendev. The LLaMA models all have a context of 2048 tokens from what I remember, and ChatGPT has about 4K tokens in its context length (for GPT-4: 8k and 32k tokens). LLaMA-30B trains 32. Assuming each parameter uses 4 bytes (32-bit float), the model size is: 7,000,000,000 parameters * 4 bytes/parameter = 28,000,000,000 bytes = 28 GB. MosaicML releases language model with 65,000 tokens context MPT-7B-Instruct is a model for following instructions, and the Chat model is a chatbot variant in the style of Alpaca or Vicuna . She is an Assistant - but unlike other Assistants, she also wants to be your friend and companion. GQA is only used in the 34B and 70B Llama 2 models. I was searching the paper/blog post but I could not find a mention of which sequence length/context length the models were trained with. Lower left illustrates Has it been published somewhere how long the context length is for ChatGPT using the GPT-4 model? The FAQ states about 3000 tokens for GPT-3. The LLaMA model was (int, optional, defaults to 2048) — The maximum sequence length that this model might ever be used with. 8GB vs 7. They mainly help in the early stages, and not as much as everything listed above; /r/StableDiffusion is back open after the protest of Reddit killing open API access, which will bankrupt app developers, hamper moderation, and exclude blind users from the site. I'm not entirely sure how they make this The documention explains, "Llama 2 pretrained models are trained on 2 trillion tokens, and have double the context length than Llama 1. 5’s size will make experimentation easier than with larger open-source models such as the Llama family [TLI+23]. Take the next token offered from each LLaMA instance, and if the tokens differ, stick it in the other LLaMA and see what it thinks the probability of that token is. cuda. 5 which should correspond to extending the max context size from 2048 to 4096. The key difference between the previous Llama-1 models is license terms, the size of the pretraining corpus increased by 40%, doubled the context length of the model to 4K, and adopted grouped TimDettmers closed this as completed on Feb 25. There are other methods that promise a context length up to 1 billion tokens (e. I am an independent researcher working on my pure RNN language model RWKV. cpp code. \n.

Since it is currently not compatible with Flash Attention 2 [13] and requires There are a few different GPT-4 models to choose from. Max token limit is just an artificial limit you can set to hard stop generation after certain amount of tokens. Our base model—Persimmon-8B-Base—performs comparably to Llama 2, despite having seen only 37% as much training data. cpp or koboldcpp, but Vicuna v1. Positional embeddings compression factor. LLaMA compares slightly favorably to both models on average. Its fine-tuned models have been trained on over 1 million human annotations. Advertisement Coins. 1 T/S. 5x less training steps than previous methods. Sign up. 5-turbo" variant, makes it well suited for use cases where a lot of text or code needs to be processed Exact VRAM consumption depends on context length and inference software. Extending Context Length in Large Language All those beautiful LLaMA based models are being kimited by their 2048 context and would be much more powerful and useful with a 4096 or, ideally a 8192 tokens-long context. Falcon 180B typically sits somewhere between GPT 3. Correct. I used Bing Chat in MPT-7B-StoryWriter-65k+ is a model designed to read and write fictional stories with super long context lengths. 7% of ChatGPT score on Vicuna GPT-4 evaluation; 🔥 80. 44x more FLOPs. Supported context window length for each model? ggerganov/llama. Why is it like that? It kinda throws me off honestly since I'm used to prompting the This will make fine tuning a thing of the past. It is only meant to illustrate that the perplexity decays as the sequence length grows longer -- it is using the longer context. Users can now access all weights and sizes via the LMSYS Org page on Hugging Face. Base Llama and any Their eval shows it's a little weaker than LLaMA-"30B" (which would actually be called 33B if it weren't for a typo in the download), which makes sense, since in the blogpost they note that: MPT-30B trains 30B params on 1T tokens. However, I am really interested in what the emergent properties of such a large context window will be. In terms of using system prompts combination with user prompts, you need to understand first 3b is small model plus dataset used to train was only 122K gpt3-5 with context length of 1024, so many advance and long prompt will not work out straightforward. 0 license. 61 seconds (10. The longer context length has an impact, though, but only when you use it. 9, and Mistral 7B 60. Thus, LLaMA on 100K would cost ~$150M. -64K+ context length. 5 on MMLU, and is on par with Google's PaLM 2-Large on HellaSwag, LAMBADA, WebQuestions, Winogrande, PIQA, ARC, BoolQ, CB, COPA, RTE, WiC, WSC, ReCoRD. The bad news is that it once again means that all existing q4_0, q4_1 and q8_0 GGMLs will no longer work with the latest llama. NOTICE: If you have been using Meta claims the pre-trained models have been trained on a massive dataset that was 40% larger than the one used for LLaMA 1. It tops most of the 13b models in most benchmarks I've seen it in (here's a compilation of llm benchmarks by u/YearZero). Finally, we show that fine-tuning LLaMA 7B with our method successfully extends its context length capacity up to 32k tokens, allowing for inference at the context lengths of GPT-4. LLaMA v2 MMLU 34B at 62. cpp. Because the previous chat history is fed in as "context" for next inference run, it has a short-term "memory" of the earlier parts of the convo. The model was trained in collaboration with How to Utilize 100k context length with CodeLlama on Oogabooga? Question | Help. is_available () else "cpu" device from transformers import T5Tokenizer, T5ForConditionalGeneration tokenizer = T5Tokenizer.

You cannot increase the context length of pretrained model. I assume this is because the GPU's utilized to the point where hardware-based rendering slows down due to insufficient resources. architecture str llama_model_loader: - kv 1: general. Llama 2 was pretrained on publicly available online data sources. from_pretrained from_pretrained (model_path_or_repo_id: str, For smartcontext, it's a tradeoff, half context is actually the minimum limit, but the actual context would be somewhere in between 0. A new development in large language models has emerged with the release of OpenLLaMA, an open-source reproduction of Meta AI's LLaMA model. Preprint. Liyang90 pushed a commit to Liyang90/llama that referenced this issue on Jul 19. I had to reduce the context length to get this to work without crashing (from 16k to 8k)—and I'm seeing the ~100% speed up you mentioned. ) Meta "increased the size of the pretraining corpus by 40%, doubled the context length of the model [to 4k], and adopted grouped-query attention (Ainslie et al. You just have to love PCs. For 1–2 example prompts, add relevant static text from external documents as prompt context and assess if the quality of the responses improves. This means that the Sun is more than 100 times wider than the Moon. Upper right illustrates length extrapolation where models are required to operate unseen positions (red dots) up to 4096. --context_size is to set the context length of the model during fine-tuning. One aspect to keep in mind is that the size of the context sent can degrade performance on other tasks. cpp (GGUF), Llama models. The model was trained in Llama-2 with 128k context length thanks to YaRN. One of the coolest things about the MPT-7B model is that it has provided the Story-Writer model MPT-7B-StoryWriter-65k+, which was trained with ALiBi architecture, allowing users to extend the LLaMA, LLaMA 2: llama: context_length: int: The maximum context length to use. We applied the same method as described in Section 4, training LLaMA 2-13B on a portion of the RedPajama dataset modified such that each data sample has a size of exactly 4096 tokens.

Specifically, from May 19th commit Compared to the first Llama, LLama 2 is trained for 2T tokens instead of 1. Our standard GPT-4 model offers 8,000 tokens for the context. 256 Limit (Almost 8 lines) Questions about LLMs & LoRa Fine-Tuning. System RAM is used for I doubt I can run it on a 3080ti with anywhere near its possible context length, and it looks like the files are too big for my 12gb of vram for now - unless someone quantizes this thing somehow. As detailed in the attached blog post above, this enables fine-tuning larger models (up to 50-60B scale Context Length \n GQA \n Llama 2 \n: A new mix of publicly available online data \n: 70B \n: 4k \n: \n: 2. Model size: LLaMA-7B has 7 billion parameters. Sure, I think with temperature you are already in right direction. Example chats of your desired length. 5% Win-rate on AlpacaEval; I'm curious how much ram it would take to get the entire context length Cut-and-pasting from my other comment: Assuming the context uses a similar amount of memory to LLaMA you can expect additional memory Step 2: Choose your LLaMA 2 model. More importantly, we demonstrate that using our method to fine-tune LLaMA 7B, a large language model, allows it to retrieve relevant information from contexts with over 32k tokens, which is the context length of GPT-4. We built Llama-2-7B-32K-Instruct with less than 200 lines of Python script using Together API, and we also make the recipe fully available. 0) and offered inference code that Deploy the customized model privately for your own use in an app, API, etc. it's a bit finnicky, yeah, but when it works it works well . It loads entirely! Remember to pull the latest ExLlama version for compatibility :D. To provide an example of this fine-tuning capability, we’re introducing Llama-2 Preliminary tests with LLaMA 7B. If you think of context length (also known as a context window) as roughly analogous to samantha-33b. So when you set it to two you were saying there are two values the one primary value and the second value in between for every single token of context. On the Code Llama was trained on a 16k context window. Thanks to our most esteemed model trainer, Mr TheBloke, we now have versions of Manticore, Nous Hermes (!!), WizardLM and so on, all with SuperHOT 8k context LoRA. , 2023). py to somehow get the array size based on the size of the model that you are loading instead of it being static. As detailed in the attached blog post above, this enables fine-tuning larger models (up to 50-60B scale models on a NVIDIA A100 80GB) at low cost. Built on the open context window of such models, requiring 10x less tokens and 2. , Hyena) but that methodology is not based on the current transformer architecture. cpp but more recent ones (like Dolly 2. Grouped-query attention (GQA) is a new optimization to tackle high memory usage due to increased context length and model size. But on 1024 context length, fine tuning spikes to 42gb of gpu memory used, so evidently it won’t be feasible to use 8k context length unless I use a ton of gpus. In the near term there has been another paper written about recurrent memory transformers (RMT) that can scale to 1-2 million tokens. ” In this context, the number 42 represents the ultimate question of existence. It was first mentioned by Douglas Adams in his book The Hitchhiker’s Guide to the Galaxy as “the answer to life, universe, and everything. All models are I'm blown away. However, when I run the LLM, OSX becomes sluggish. 5% win-rate on Photo by Emiliano Vittoriosi / Unsplash. - GitHub - oobabooga/text-generation-webui: A Gradio web UI for Large Language Models. 512 tokens means the model is learning to attend to only 512 tokens, and Llama isn't very good at generalizing beyond that. Vicuna got some great results and achieved a quality score of more than 90% when compared to other famous chatbots such as ChatGPT and Google Bard. LLAMA 13b outperforms GPT-3 on most benchmarks and LLAMA 65b is competitive with the latest models like Chinchilla 70b on a variety of tasks. As part of first run it'll download the 4bit 7b model if it doesn't exist in the models folder, but if you already have it, you can drop the "llama-7b-4bit. Dev team released a more compact 3B base variant (not instruction tuned) of the LongLLaMA model under a lenient license (Apache 2. 6 and 70B now at 68. -1: gpu_layers: int: The number of layers to run on GPU. It achieves context extension by modifying the attention mechanism and thus is not purely an embedding interpolation method. Big thanks to <PRESIDIO_ANONYMIZED_PERSON>, Andrei Abetlen, Eric Hartford, TheBloke and the Mistral team for making this stuff so easy to put together in an afternoon. I also believe that TokenMonster vocabularies will improve the comprehension of Large Giraffe is an open-source LLM with a context window of 32,000 tokens, making it useful for many applications in business contexts. 4T, has 2x the context length (4096 instead of 2048), uses Grouped Query Attention, and performs better across the board, with performance generally exceeding code-davinci-002 on benchmarks:. LongLLaMA Code stands upon the base of Code Llama. Indeed, phi-1. In the I have a 3090 with 24GB VRAM and 64GB RAM on the system. (1. from_pretrained The problem I see with all of these models is that the context size is tiny compared to GPT3/GPT4. We present Position Interpolation (PI) that extends the context window sizes of RoPE-based (su2021roformer) pretrained LLMs such as LLaMA (touvron2023llama) models to up to 32768 with minimal fine-tuning (within 1000 steps), while demonstrating strong empirical results on various tasks that require long context, including passkey retrieval, language Llama 2’s context length is doubled to 4,096. g 3. class AutoModelForCausalLM. 5 x 10-4: Llama 2 family of models. The LLaMA models are the latest large language models developed by Meta AI. Achieves 80. For this purpose, LLaMA models were trained on Modern large language models (LLMs) that rely on attention mechanisms are typically trained with fixed context lengths which enforce upper limits on the length of input sequences that they can handle at evaluation time. safetensors file: .

LLaMA: The number 42 has been used in many different ways throughout history, and it continues to be used today. We have already tokenized the validation and test splits of PG19 and proof-pile dataset into pg19/validation. I profiled it using pytorch profiler with a tensorboard extension (it can also profile vram usage), and then did some stepping through the code in a vscode debugger. [R] Efficient Streaming Language Models with Attention Sinks - Meta AI 2023 - StreamingLLM enables Llama-2, Falcon and Pythia to have an infinite context length without any fine-tuning! Try this if your prompts get cut off on high context lengths. I posted a few logs of the interactions I had with it in my previous comments, so you can check that if you want. 15595. The model has identical performance to Llama 2 under 4k context length, performance scales directly to 8k, and works out-of-the-box with the new version of transformers (4. Used by LLaMA 1/2 models family: Vicuna, Hermes, Airoboros, etc. Subjects: Computation and Language (cs. NerdStash tokenizer. You should NOT use a different context length unless the model is fine-tuned for an extended context length. cpp, it's just slow. It performed better than chatbot models like LLaMA and Stanford Alpaca in more than 90% of cases. There are new weights which needs to be optimised to get correct result , which requires training. The fine-tuned model, Llama-2-chat, leverages publicly A Gradio web UI for Large Language Models. 02) — The standard deviation of the truncated_normal_initializer for 2. A possible explanation for the hallucinations you're seeing is that the model has gotten worse at dealing with longer contexts. Info: CPU: 4 cores RAM: 16G Model: 7B RAM used during generation is 4. 9% win-rate on AlpacaEval. Projects. LLama doesn't use sparse Project. Built on the open-source OpenLLaMA and fine-tuned using the Focused Transformer (FoT) method, it permits some attention layers to access a memory cache of key-value pairs to extend their context Sorry to hear that! Testing using the latest Triton GPTQ-for-LLaMa code in text-generation-webui on an NVidia 4090 I get: act-order. The alpaca models I've seen are the same size as the llama model they are trained on, so I would expect running the alpaca-30B models will be possible on any system capable of running llama-30B. I can even run fine-tuning with 2048 context length and mini_batch of 2. It reduces memory usage by sharing the cached keys and values of the previous tokens. CL); Machine Learning (cs. However, it’s important to note that this comes with a trade-off. Falcon 180B is the best openly released LLM today, outperforming Llama 2 70B and OpenAI’s GPT-3. The benefit is you can finetune to any length and get good perplexity up to 2x that length. See for yourself. Sports. I'd run it in the cloud but I've never done that and don't even know where to start for a model like this - I don't know what kind of beef it's going to take to run it, or where to On research benchmarks, our models achieve consistent improvements on most regular tasks and significant improvements on long-context tasks over LLAMA 2. LLaMA 2 model with a 32k context window is here, yes you are right, 32,000 tokens can be inputted or either be outputted, you can generate or give as an Text Generation Web UI with Long-Term Memory. So, generally speaking, Max context window - length of your prompt = how much model can generate. 2, and the memory doesn't move from 40GB reserved. Quote Tweet. I can work with 4096 and am not looking for more, yet, but its not possible for me to go back to 2048 as the information that I need the LLM to consider simply does not fit inside the 2048 token prompt + response You can run llama-30B on a CPU using llama. compress_pos_emb is for models/loras trained with RoPE scaling. The key to the approach is to carve a long context into chunks (``windows'') that fit within the architecture, restrict the attention mechanism to apply only within each window, and re-use the Consider a Llama model pre-trained with a 2048 context window length. LLaMA (Large Language Model Meta AI), a state-of-the-art foundational large language model designed to help researchers advance their work in this subfield of AI. I think it fared pretty well given it hasn't been fine tuned at all for 6000+ context size. NFL NBA Megan Anderson I run llama 65b 4 bit daily since a week or a bit more and the only time it was incoherent is when it was generating output after the base context size was filled up and I guess it was shifting kv cache. Sign in.

I am using qlora (brings down to 7gb of gpu memory) and using ntk to bring up context length to 8k. 8, Mistral Open Orca 66. Here are my highlights from the paper: Big one of course: LongLoRA efficiently fine-tunes large AI models on longer texts Key points: In this paper, we present a novel approach that allows access to the complete context while retaining random-access flexibility, closely resembling running attention on the entire context. One option is to train the model on 2K tokens context and then fine-tune it in longer contexts (for example, 65K). Is there anyway to lower memory so LLaMA Overview . Tess, welcome to the world! Model is Open Source with 200K context length. embeddings = np. Ie 7B now performs at old 13B etc. To extend it to 32K context, three things need to come together: modeling, data, and system optimizations. Increasing Llama 2’s 4k context window to Code Llama’s 16k (that can extrapolate up to 100k) was possible due to recent developments in RoPE LLaMA Overview . This is still the beginning of the beginning. Consider a Llama model pre-trained with a 2048 context window length. 16,384. other open source models on academic tasks (From Mosaic). 0T \n: 1. Variations Llama 2 comes in a range of parameter sizes — 7B, 13B, and 70B — as well as MPT uses ALiBi which is a relative bias applied directly on the dot product of QK. The GPT-4 model has been trained on a massive 1+ trillion parameters and supports a maximum context length of 32,768 tokens. For example if you only need a yes or no Interesting, in my case it runs with 2048 context, but I might have done a few other things as well — I will check later today. Note RWKV is parallelizable too, so it's combining the best of RNN and transformer. 45. The 70B version uses Grouped-Query Attention (GQA) for improved Llama2 70B GPTQ full context on 2 3090s. Here are my highlights from the paper: Big one of course: LongLoRA efficiently fine-tunes large AI models on longer texts Key points: It just couldn't do anything about it. io and paper from Meta 2306. And many of these are 13B models that should work well with lower VRAM count GPUs! I recommend trying to load with Exllama (HF if possible). g. Context length settings for llama 2 models. It is not a proper comparison of the perplexity loss between We will need to calculate the memory requirements for the model and the input tokens. Smaller: LLaMa is 65 billion parameters while Falcon-40B is only 40 billion parameters, so it requires less memory. A longer context window allows the model to understand long-range dependencies in text better Open in app. Llama 1 supports up to 2048 tokens, Llama 2 up to 4096, CodeLlama up to 16384. context_length u32 Excited for long context windows. I randomly made somehow 70B run with a variation of RAM/VRAM offloading but it run with 0. I was able to a single forward pass within 9GB of memory which is astounding. Each version of Vicuna comes separately – meaning you can choose to download your preferred parameter size with either 4K or 16K context length. Researchers have released a preview of LongLLaMA, a large language model capable of handling long contexts up to 256. So if you have 2048 and your prompt is 1000, you have 1048 tokens left for model to fill in. Do we know which one is being used under the hood? We kindly ask u/nuclear_knucklehead to respond to this comment with This repo contains the code and data for the YaRN context window extension method. 1. -=- I see that you also uploaded a LLongMA-2-7b-16k, which is extremely fascinating. It does not use position encoding, only bias, so similar approach would not work. We train our models on trillions of tokens, and show that it is possible to train state-of-the-art models using publicly available datasets exclusively, without resorting to proprietary and inaccessible datasets. 5 bpw that run fast but the context window of such models, requiring 10x less tokens and 2.

Our method uses a landmark token to represent each block of the input and trains the attention to use it for selecting relevant blocks, enabling Llama-2-7B-32K-Instruct Model Description Llama-2-7B-32K-Instruct is an open-source, long-context chat model finetuned from Llama-2-7B-32K, over high-quality instruction and chat data. Next, pick your size range. Besides, if you want 260k MPT you need to finetune on 130k samples. Equal to 1/rope_freq_scale MPT-30B comes with a longer context window MPT-30B has also been trained on longer sequences (up to 8,000 tokens) than GPT-3, LLaMA or Falcon (2,000 tokens each). Using YaRN, we show that LLaMA models can effectively utilize and This is quite different from Open AI's GPT 3 where "you" tends to refer to the assistant or LLM. We publish variants of Llama 2 fine-tuned with YaRN at 32K, 64K and 128K context window length. Also --loader exllama_hf --max_seq_len 16384 --alpha Our model can process any context length at inference time regardless of the context length used at training time. NerdStash v2 tokenizer. Total: 331G I did a quick experiment with Pytorch 2. The code-optimized tokenizers do even better, see for yourself . Variants such as Neat stuff! I'll end up waiting for the ggml variant (my 1060 6GB prefers koboldcpp for some reason), but I'm excited to try it. That's something you cannon change w/o changing the model? Does it imply that you can go above 2000k like above bryanhpchiang commented Mar 16, 2023 what's the supported context window length for each model? I have changed the parameter -n to -n 1048 the context is longer by almost ~50% but still not able to generate long text, then changed it to -n 4096 and got almost Subreddit to discuss about Llama, the large language model created by Meta AI. 3 billion parameter language model that achieves strong performance on common sense reasoning and coding tasks, comparable to models 5-10x its size. On Hugging Face, the base 34B model stood out with a performance better than the much larger pre-trained base LLMs, including The context length for these models is 4096 tokens. There's a little sidenote not mentioned: static memory (the stuff at the start of your prompt that never changes) is excluded from smartcontext, the trimming only happens in the dynamically Llama2 70B GPTQ full context on 2 3090s. A model like LLaMA with 64k context length well you can teach it almost anything with different prompts and Researchers have released a preview of LongLLaMA, a large language model capable of handling long contexts up to 256. In addition, the three model variants had additional long-context fine-tuning, allowing them to manage a Extending the vocabulary size of the llama model. Model Developers Meta \n. I The native context length for Llama 1 and 2 are 2,024 and 4,096 tokens. generating 2048 tokens out of a 4096 token context will go at the same speed as 2048 tokens in a 2048 token context, but the speed decreases somewhat as you get further into the sequence. empty ( (len (chunks), 5120)) Edit2: for llama 65B it has to be set to 8192. --seq_len should not be larger than --context_size. it's the only model i've come across that can actually write stories.

The Mistral AI team releases Mistral 7B, a 7. I think by patching existing Pretrained GPT models and adding more positional encodings, one could easily fine-tune those models to 32k attention on a single A100 80GB. A context length like that would let someone load a large amount of "world information" into it and still get extremely coherent results. Trained on 1T tokens of text+code, MPT models match and - in many ways - surpass Meta built LLama Long on the foundation of OpenLLaMA and refined it using the Focused Transformer (FoT) method. I've read that the behavior of a LoRA trained with 256 cutoff length/token context also suffers from that limitation, and it can't "see" beyond the 256 tokens when used. Our instruction-fine-tuned model—Persimmon-8B-FT—is the strongest performing model on all but one of the metrics. md to use pip3 ( facebookresearch#16) 870e2cc.

An I have changed the parameter -n to -n 1048 the context is longer by almost ~50% but still not able to generate long text, then changed it to -n 4096 and got almost the same length as -n 1048. 6% of ChatGPT score on Vicuna GPT-4 evaluation; 79. Has there been any open source notebooks that cover extending the model vocabulary size and fine turning it on a new Labels. Notably, with a cost-effective instruction tuning procedure that does not require human-annotated long instruction data, the 70B variant can already surpass gpt-3. However, one of the biggest challenges of using LLMs is the cost of accessing them. In this repo, we present a permissively licensed open source reproduction of Meta AI's LLaMA large language model. 15595] Extending Context Window of Large Language Models via Positional Interpolation (arxiv. I propose all What is the maximum token limit of llama? Is it 1024, 2048, 4096, or longer? for example, GPT-4 has a maximum token limit of 32,000 (equivalent to 25,000 words) Baked-in 2048 token context limit in LLaMa, apparently. Free : Falcon models are distributed under an Apache 2. NOTICE: This extension may conflict with other extensions that modify the context. LLaMA tried to filter things but it's in the common crawl data (they think) so there will always be biases in the base model anyway. 9% Win-rate on AlpacaEval; 🤗 Only used 6K data for finetuning!!! OpenChat-8192: based on LLaMA-13B (extended to 8192 context length) 106. 0 of the max context length. It seems like due to the x2 in tokens (2T), the MMLU performance also moves up 1 spot. Write. 5, and the base GPT-4 is capable of ~8000 or ~32000, depending on the model. [4]: Probably very similar to LLaMA-7B equivalent [5]: This is not the metric alpaca tries to improve. With Exllama as the loader and xformers enabled on oobabooga and a 4-bit quantized model, llama-70b can run on 2x3090 (48GB vram) at full 4096 context length and do 7-10t/s with the split set to 17. It's something that the 1st public 120k plus context model is open source! The cost to run this thing at scale would be insane. More info: https://rtech. In my own (very informal) testing I've found it to be a better all-rounder and make less mistakes than my previous -Base 7B LLM trained on 1T tokens outperforms LLaMA and GPT3. 12x 70B, LLaMA-2 has a context length of 4K tokens.
