Chat with multiple bots with different personalities, hosted locally or with OpenAI, in the comfort of a beautiful 1970's terminal-themed REPL.
Llama-farm has a long-term chat memory that recalls previous conversations. A summary of previous conversation relevant to the topic (automatically determined) is available to the active bot.
Ask it questions about your own documents and information, stored in a local vector knowledge store. I recommend you are selective about what you ingest in order to improve the relevance of results. The quality of information available is more important than the quantity.
It can summarize long texts like Youtube video transcripts, URLs and text files. You can discuss the content of those sources and it can extract the relevant parts.
You can ask it questions with access to YouTube, arXiv, wikipedia, URLs and text files.
Llama-farm speaks to any OpenAI-compatible API:
- llama-api (recommended)
- oobabooga/text-generation-webui (via its OpenAI-compatible API extension)
- OpenAI (recommended)
- lm-sys/FastChat (untested)
- keldenl/gpt-llama.cpp (untested)
Llama-farm uses hwchase17/langchain for the vectordb abstraction and splitting of long documents (see limitations).
The storage is backed by faiss. The wrapper to chromadb is written but is not currently used or tested.
The help text is here.
BREAKING CHANGES:
- the default embedding for the vector db changed in 0.6.0
to allow longer text fragments. You'll either need to replace your old vector
dbs (under
storage/) or change back the embedding and chunk sizes under the storage section in the config file. Other format changes in the config file need to be reflected in your config also (see the example config). - Also, the config file format has changed since 0.7.0, since using the OpenAI API directly.
Copy the config.toml.example to config.toml.
To use openAI, you need to set your key in config.toml.
There are a lot of dependencies so it's recommended you install
everything in a virtual environment. Either clone the repo, install
the requirements.txt and run the module
$ <activate your venv>
$ git clone https://github.com/atisharma/llama_farm
$ cd llama_farm
$ pip install -r requirements.txt
$ python -m llama_farm
Or, install using pip
$ <activate your venv>
$ pip install git+https://github.com/atisharma/llama_farm
$ llama-farm
If you want to use bark TTS on a different cuda device from your
language inference one, you can set the environment variable
CUDA_VISIBLE_DEVICES to point to the appropriate graphics card
before you run llama-farm. For example, run the LLM server on one
graphics card and llama-farm's TTS on a weaker one.
Llama-farm works very well with OpenAI's gpt-3.5-turbo. Wizard-Vicuna-Uncensored, WizardLM, etc also work very well. It even works surprisingly well with WizardLM-7B! But see limitations below.
- Larger LLaMA models (30B) work much better for complex tasks.
- The context length limitation of Llama models (2048 tokens) is half or less that of OpenAI's models.
- The OpenAI API (and compatible ones) do not expose a number of capabilities that local models have.
- The
ingestcommand (from command line or within the chat) can't be used concurrently - one instance will overwrite the changes of another.
- You can grep the codebase for "TODO:" tags; these will migrate to github issues
- Document recollection from the store is rather fragmented. It may be better to use similarity search just as a signpost to the original document, then summarize the document as context.
- Reconsider store document size, since summarization works well
- Define tools for freeform memory access rather than /command syntax
- Define JSON API templates for other web tools
- Self-chat between bots with intention/task injection; see e.g. operand/agency
- Use of tools (see tools.hy)
- Task planning? (see tasks.hy)
