The table below shows the F1 scores for these tasks: | Model | Toxicity Detection | Irony Detection | Sentiment Analysis | |----------------------------------------------|--------------------|-----------------|--------------------| | **cerbero-7b-openchat** | **63.33%** | **69.16%** | **66.89%** | | **cerbero-7b** | **63.04%** | **48.51%** | **61.80%** | | Fauno | 33.84% | 39.17% | 12.23% | | Camoscio | 38.18% | 39.65% | 13.33% | | mistral-7b | 34.16% | 34.16% | 12.14% | ## Why Cerbero? πŸ€” The name "Cerbero," inspired by the three-headed dog that guards the gates of the Underworld in Greek mythology, encapsulates the essence of our model, drawing strength from three foundational pillars: - **Base Model: mistral-7b** πŸ—οΈ cerbero-7b builds upon the formidable **mistral-7b** as its base model. This choice ensures a robust foundation, leveraging the power and capabilities of a cutting-edge language model. - **Datasets: Cerbero Dataset** πŸ“š The Cerbero Dataset is a groundbreaking collection specifically curated to enhance the proficiency of cerbero-7b in understanding and generating Italian text. This dataset is a product of an innovative method combining dynamic self-chat mechanisms with advanced Large Language Model (LLM) technology. Refer to the [paper](https://arxiv.org/abs/2311.15698) for more details. - **Licensing: Apache 2.0** πŸ•ŠοΈ Released under the **permissive Apache 2.0 license**, cerbero-7b promotes openness and collaboration. This licensing choice empowers developers with the freedom for unrestricted usage, fostering a community-driven approach to advancing AI in Italy and beyond. ## Models 🧬 **cerbero-7b** is available in various flavors, each tailored for specific applications and use cases. Below is a table listing these versions along with their respective training datasets and base models: | Model Name | Training Dataset | Base Model | Huggingface Model | Llama.cpp and Quantized Model | |-------------------------|-------------------|-------------|-------------------|-------------------------------| | cerbero-7b | Cerbero Dataset | mistral-7b | [link](https://huggingface.co/galatolo/cerbero-7b) | [link](https://huggingface.co/galatolo/cerbero-7b-gguf) | | cerbero-7b-openchat | Cerbero Dataset | openchat3.5 | [link](https://huggingface.co/galatolo/cerbero-7b-openchat) | [link](https://huggingface.co/galatolo/cerbero-7b-openchat-gguf) | Each of these models brings its unique strengths to the table, making **cerbero-7b** a versatile tool for both research and commercial applications in the Italian language AI domain. We are committed to continuously enhancing **cerbero-7b**. Our team plans to keep training and releasing new models as advancements in the 7b SOTA occur. This ensures that **cerbero-7b** remains at the forefront of AI technology, offering the most advanced and efficient solutions in the Italian language AI sector. If you do not have enough RAM to fit the `float32` model (for example when using Colab) we provide for each model a `float16` version using the `revision="float16"` argument ```python model = AutoModelForCausalLM.from_pretrained("galatolo/cerbero-7b", revision="float16") ``` ## Training Details πŸš€ **cerbero-7b** is a **fully fine-tuned** LLM, distinguishing itself from LORA or QLORA fine-tunes. The model is trained on an expansive Italian Large Language Model (LLM) using synthetic datasets generated through dynamic self-chat on a large context window of **8192 tokens** ### Dataset Composition πŸ“Š > πŸ“’ Details on the **Cerbero Dataset** will be updated shortly! ### Training Setup βš™οΈ **cerbero-7b** is trained on an NVIDIA DGX H100: - **Hardware:** Utilizing 8xH100 GPUs, each with 80 GB VRAM. πŸ–₯️ - **Parallelism:** DeepSpeed Zero stage 1 parallelism for optimal training efficiency.✨ The model has been trained for **1 epoch**, ensuring a convergence of knowledge and proficiency in handling diverse linguistic tasks. ## Prompt Format **cerbero-7b** is trained on full conversations using the following prompt format: ``` [|Umano|] First human message [|Assistente|] First AI reply [|Umano|] Second human message [|Assistente|] Second AI reply ``` When crafting prompts, ensure to conclude with the `[|Assistente|]` tag, signaling the AI to generate a response. Use `[|Umano|]` as stop word. For example: ``` [|Umano|] Come posso distinguere un AI da un umano? [|Assistente|] ``` While it's possible to include a brief system message at the start of your prompt, remember that the training data for **cerbero-7b** **does not** contain such **system messages**. Hence, it's recommended to minimize or avoid including them for optimal model performance. ## Getting Started πŸš€ You can load **cerbero-7b** (or **cerbero-7b-openchat**) using [πŸ€—transformers](https://huggingface.co/docs/transformers/index) ```python import torch from transformers import AutoModelForCausalLM, AutoTokenizer model = AutoModelForCausalLM.from_pretrained("galatolo/cerbero-7b") tokenizer = AutoTokenizer.from_pretrained("galatolo/cerbero-7b") prompt = """Questa Γ¨ una conversazione tra un umano ed un assistente AI.

The training dataset for the released models was generated using `garage-bAInd/Platypus2-70B-instruct` instead of `meta-llama/Llama-2-7b-chat-hf`, due to the more permissive license of the Platypus2 model (CC-BY-NC 4.0). Our tests indicate that both models produce datasets of comparable quality, and the resulting fine-tuned models demonstrate nearly indistinguishable performance.
