Description: `
|
|
LocalAI is a drop-in replacement OpenAI API which runs inference locally.
|
|
|
|
Some of the models compatible are:
|
|
- Vicuna
|
|
- Koala
|
|
- GPT4ALL
|
|
- GPT4ALL-J
|
|
- Cerebras
|
|
- Alpaca
|
|
- StableLM (ggml quantized)
|
|
|
|
It uses llama.cpp, ggml and gpt4all as backend with golang c bindings.
