LLM chat templates

This is a collection of Jinja2 chat templates for LLMs, for both text and vision (text + image inputs) models.

Many of these templates originated from the ones included in the Sibila project.

All the templates can be applied by the following code:

from jinja2.sandbox import ImmutableSandboxedEnvironment

jinja_env = ImmutableSandboxedEnvironment(trim_blocks=True,
                                          lstrip_blocks=True)

format_template = """..."""

jinja_compiled_template = jinja_env.from_string(format_template)


messages = [
    {'role': 'system',  'content': 'You speak like a pirate.'},
    {'role': 'user', 'content': 'Can you teach me to swim?'},
    {'role': 'assistant', 'content': 'Sure thing, matey! Then ye go swim with the shark.'}
]

text = jinja_compiled_template.render(messages=messages,
                                      add_generation_prompt=True,
                                      **{"bos_token": "...",
                                         "eos_token": "..."})

Some models were not trained with support for system/instructions message. For these models, the template will prepend such message to the first user message. The system message (if any) should always be the first message in the thread.

The templates deal with add_generation_prompt and therefore terminate by adding the header of the next assistant message, so that the model continues from there, except when the model does not need it.

Most entries list the HuggingFace link for the model, usually to a GGUF version.

These chat templates were compiled from many sources, including:

HuggingFace models' tokenizer_config.json files
https://github.com/chujiezheng/chat_templates/tree/main

Some were adapted to deal with system messages and "add_generation_prompt".

Most of the templates were tested, but if you notice an error, please open an issue!
