The goal of the ML.ENERGY Leaderboard is to give people a sense of how much **energy** LLMs would consume.
## How is energy different?
The energy consumption of running inference on a model will depends on factors such as architecture, size, and GPU model.
However, even if we run models with the exact same architecture and size on the same GPU, the average energy consumption **per prompt** is different because different models have **different verbosity**.
That is, when asked the same thing, different models answer in different lengths.
## Metrics
- `gpu`: NVIDIA GPU model name
- `task`: Name of the task. See *Tasks* below for details.
- `throughput` (token/s): The average number of tokens generated per second.
- `response_length` (token): The average number of tokens in the model's response.
- `latency` (s): The average time it took for the model to generate a response.
- `energy` (J): The average energy consumed by the model to generate a response.
- `parameters`: The number of parameters the model has, in units of billion.
## Tasks
For each task, every model uses the same system prompt. We still account for differences in roles, e.g. `USER`, `HUMAN`, `ASSISTANT`, `GPT`.
| Name | System prompt |
|--|--|
| chat | A chat between a human user (prompter) and an artificial intelligence (AI) assistant. The assistant gives helpful, detailed, and polite answers to the user's questions. |
| chat-concise | A chat between a human user (prompter) and an artificial intelligence (AI) assistant. The assistant gives helpful, detailed, and polite answers to the user's questions. The assistant's answers are very concise. |
| instruct | Below is an instruction that describes a task. Write a response that appropriately completes the request. |
| instruct-concise | Below is an instruction that describes a task. Write a response that appropriately completes the request. The response should be very concise. |
## Setup
Find our benchmark script for one model [here](https://github.com/ml-energy/leaderboard/blob/master/benchmark.py).
### Software
- PyTorch 2.0.1
- [FastChat](https://github.com/lm-sys/fastchat) -- For various model support
- [Zeus](https://ml.energy/zeus) -- For GPU energy measurement
### Hardware
- NVIDIA A40 GPU
### Parameters
- Model
- Batch size 1
- FP16
- Sampling (decoding)
- Greedy sampling from multinomial distribution
- Temperature 0.7
- Repetition penalty 1.0
## Data
We randomly sampled around 3000 prompts from the [cleaned ShareGPT dataset](https://huggingface.co/datasets/anon8231489123/ShareGPT_Vicuna_unfiltered).
See [here](https://github.com/ml-energy/leaderboard/tree/master/sharegpt) for more detail on how we created the benchmark dataset.
We used identical system prompts for all models (while respecting their own *role* tokens):
```

```
## Upcoming
- Compare energy numbers against more optimized inference runtimes, like TensorRT.
- More GPU types
- More models
