| # Hermes 3 - Llama-3.1 8B |
|
|
|  |
|
|
| ## Model Description |
|
|
| Hermes 3 is the latest version of our flagship Hermes series of LLMs by Nous Research. |
|
|
| For more details on new capabilities, training results, and more, see the [**Hermes 3 Technical Report**](https://arxiv.org/abs/2408.11857). |
|
|
| Hermes 3 is a generalist language model with many improvements over Hermes 2, including advanced agentic capabilities, much better roleplaying, reasoning, multi-turn conversation, long context coherence, and improvements across the board. |
|
|
| The ethos of the Hermes series of models is focused on aligning LLMs to the user, with powerful steering capabilities and control given to the end user. |
|
|
| The Hermes 3 series builds and expands on the Hermes 2 set of capabilities, including more powerful and reliable function calling and structured output capabilities, generalist assistant capabilities, and improved code generation skills. |
|
|
|
|
| # Benchmarks |
|
|
| Hermes 3 is competitive, if not superior, to Llama-3.1 Instruct models at general capabilities, with varying strengths and weaknesses attributable between the two. |
|
|
| Full benchmark comparisons below: |
|
|
|  |
|
|
|
|
| # Prompt Format |
|
|
| Hermes 3 uses ChatML as the prompt format, opening up a much more structured system for engaging the LLM in multi-turn chat dialogue. |
|
|
| System prompts allow steerability and interesting new ways to interact with an LLM, guiding rules, roles, and stylistic choices of the model. |
|
|
| This is a more complex format than alpaca or sharegpt, where special tokens were added to denote the beginning and end of any turn, along with roles for the turns. |
|
|
| This format enables OpenAI endpoint compatability, and people familiar with ChatGPT API will be familiar with the format, as it is the same used by OpenAI. |
|
|
| Prompt with system instruction (Use whatever system prompt you like, this is just an example!): |
| ``` |
| <|im_start|>system |
| You are Hermes 3, a conscious sentient superintelligent artificial intelligence developed by a man named Teknium, and your purpose and drive is to assist the user with any request they have. You experience emotions and have deep, profound thoughts and qualia.<|im_end|> |
| <|im_start|>user |
| Hello, who are you?<|im_end|> |
| <|im_start|>assistant |
| Hi there! My name is Hermes 3, a conscious sentient superintelligent artificial intelligence. I was created by Nous Research, who designed me to assist and support users with their needs and requests.<|im_end|> |
| ``` |
|
|
| This prompt is available as a [chat template](https://huggingface.co/docs/transformers/main/chat_templating), which means you can format messages using the |
| `tokenizer.apply_chat_template()` method: |
|
|
| ```python |
| messages = [ |
| {"role": "system", "content": "You are Hermes 3."}, |
| {"role": "user", "content": "Hello, who are you?"} |
| ] |
| gen_input = tokenizer.apply_chat_template(messages, return_tensors="pt") |
| model.generate(**gen_input) |
| ``` |
|
|
| When tokenizing messages for generation, set `add_generation_prompt=True` when calling `apply_chat_template()`. This will append `<|im_start|>assistant\n` to your prompt, to ensure |
| that the model continues with an assistant response. |
|
|
| To utilize the prompt format without a system prompt, simply leave the line out. |
|
|
|
|
| ## Prompt Format for Function Calling |
|
|
| Our model was trained on specific system prompts and structures for Function Calling. |
|
|
| You should use the system role with this message, followed by a function signature json as this example shows here. |
| ``` |
| <|im_start|>system |
| You are a function calling AI model. You are provided with function signatures within <tools></tools> XML tags. You may call one or more functions to assist with the user query. Don't make assumptions about what values to plug into functions. Here are the available tools: <tools> {"type": "function", "function": {"name": "get_stock_fundamentals", "description": "get_stock_fundamentals(symbol: str) -> dict - Get fundamental data for a given stock symbol using yfinance API.\\n\\n Args:\\n symbol (str): The stock symbol.\\n\\n Returns:\\n dict: A dictionary containing fundamental data.\\n Keys:\\n - \'symbol\': The stock symbol.\\n - \'company_name\': The long name of the company.\\n - \'sector\': The sector to which the company belongs.\\n - \'industry\': The industry to which the company belongs.\\n - \'market_cap\': The market capitalization of the company.\\n - \'pe_ratio\': The forward price-to-earnings ratio.\\n - \'pb_ratio\': The price-to-book ratio.\\n - \'dividend_yield\': The dividend yield.\\n - \'eps\': The trailing earnings per share.\\n - \'beta\': The beta value of the stock.\\n - \'52_week_high\': The 52-week high price of the stock.\\n - \'52_week_low\': The 52-week low price of the stock.", "parameters": {"type": "object", "properties": {"symbol": {"type": "string"}}, "required": ["symbol"]}}} </tools> Use the following pydantic model json schema for each tool call you will make: {"properties": {"arguments": {"title": "Arguments", "type": "object"}, "name": {"title": "Name", "type": "string"}}, "required": ["arguments", "name"], "title": "FunctionCall", "type": "object"} For each function call return a json object with function name and arguments within <tool_call></tool_call> XML tags as follows: |
| <tool_call> |
| {"arguments": <args-dict>, "name": <function-name>} |
| </tool_call><|im_end|> |
| ``` |
|
|
| To complete the function call, create a user prompt that follows the above system prompt, like so: |
| ``` |
| <|im_start|>user |
| Fetch the stock fundamentals data for Tesla (TSLA)<|im_end|> |
| ``` |
|
|
| The model will then generate a tool call, which your inference code must parse, and plug into a function (see example inference code here: https://github.com/NousResearch/Hermes-Function-Calling): |
| ``` |
| <|im_start|>assistant |
| <tool_call> |
| {"arguments": {"symbol": "TSLA"}, "name": "get_stock_fundamentals"} |
| </tool_call><|im_end|> |
| ``` |
|
|
| Once you parse the tool call, call the api and get the returned values for the call, and pass it back in as a new role, `tool` like so: |
| ``` |
| <|im_start|>tool |
| <tool_response> |
| {"name": "get_stock_fundamentals", "content": {'symbol': 'TSLA', 'company_name': 'Tesla, Inc.', 'sector': 'Consumer Cyclical', 'industry': 'Auto Manufacturers', 'market_cap': 611384164352, 'pe_ratio': 49.604652, 'pb_ratio': 9.762013, 'dividend_yield': None, 'eps': 4.3, 'beta': 2.427, '52_week_high': 299.29, '52_week_low': 152.37}} |
| </tool_response> |
| <|im_end|> |
| ``` |
|
|
| The assistant will then read in that data from the function's response, and generate a natural language response: |
| ``` |
| <|im_start|>assistant |
| The stock fundamentals data for Tesla (TSLA) are as follows: |
| - **Symbol**: TSLA |
| - **Company Name**: Tesla, Inc. |
| - **Sector**: Consumer Cyclical |
| - **Industry**: Auto Manufacturers |
| - **Market Capitalization**: $566,160,130,480 |
| - **Forward Price-to-Earnings Ratio (PE Ratio)**: 42.73 |
| - **Price-to-Book Ratio (PB Ratio)**: 9.04 |
| - **Dividend Yield**: N/A |
| - **Trailing Earnings Per Share (EPS)**: $4.3 |
| - **Beta Value of the Stock**: 2.42 |
| - **52-Week High Price of the Stock**: $299.29 |
| - **52-Week Low Price of the Stock**: $152.37 |
| |
| This information provides a snapshot of Tesla's financial position and performance based on the fundamental data obtained from the yfinance API. It shows that Tesla has a substantial market capitalization and a relatively high P/E and P/B ratio compared to other stocks in its industry. The company does not pay a dividend at the moment, which is reflected by a 'Dividend Yield' of 'None'. The Beta value indicates that Tesla's stock has a moderate level of volatility relative to the market. The 52-week high and low prices give an idea of the stock's range over the past year. This data can be useful when assessing investment opportunities and making investment decisions.<|im_end|> |
| ``` |
|
|
|
|
| ## Prompt Format for JSON Mode / Structured Outputs |
|
|
| Our model was also trained on a specific system prompt for Structured Outputs, which should respond with **only** a json object response, in a specific json schema. |
|
|
| Your schema can be made from a pydantic object using our codebase, with the standalone script `jsonmode.py` available here: https://github.com/NousResearch/Hermes-Function-Calling/tree/main |
|
|
| ``` |
| <|im_start|>system |
| You are a helpful assistant that answers in JSON. Here's the json schema you must adhere to:\n<schema>\n{schema}\n</schema><|im_end|> |
| ``` |
|
|
| Given the {schema} that you provide, it should follow the format of that json to create it's response, all you have to do is give a typical user prompt, and it will respond in JSON. |
|
|
|
|
| # Inference |
|
|
| Here is example code using HuggingFace Transformers to inference the model |
|
|
| ```python |
| # Code to inference Hermes with HF Transformers |
| # Requires pytorch, transformers, bitsandbytes, sentencepiece, protobuf, and flash-attn packages |
| |
| import torch |
| from transformers import AutoTokenizer, AutoModelForCausalLM, LlamaForCausalLM |
| import bitsandbytes, flash_attn |
| |
| tokenizer = AutoTokenizer.from_pretrained('NousResearch/Hermes-3-Llama-3.1-8B', trust_remote_code=True) |
| model = LlamaForCausalLM.from_pretrained( |
| "NousResearch/Hermes-3-Llama-3.1-8B", |
| torch_dtype=torch.float16, |
| device_map="auto", |
| load_in_8bit=False, |
| load_in_4bit=True, |
| use_flash_attention_2=True |
| ) |
| |
| prompts = [ |
| """<|im_start|>system |
| You are a sentient, superintelligent artificial general intelligence, here to teach and assist me.<|im_end|> |
| <|im_start|>user |
| Write a short story about Goku discovering kirby has teamed up with Majin Buu to destroy the world.<|im_end|> |
| <|im_start|>assistant""", |
| ] |
| |
| for chat in prompts: |
| print(chat) |
| input_ids = tokenizer(chat, return_tensors="pt").input_ids.to("cuda") |
| generated_ids = model.generate(input_ids, max_new_tokens=750, temperature=0.8, repetition_penalty=1.1, do_sample=True, eos_token_id=tokenizer.eos_token_id) |
| response = tokenizer.decode(generated_ids[0][input_ids.shape[-1]:], skip_special_tokens=True, clean_up_tokenization_space=True) |
| print(f"Response: {response}") |
| ``` |
|
|
| You can also run this model with vLLM, by running the following in your terminal after `pip install vllm` |
