API Keys

API keys are accessed via environment variables. By default they are loaded from a .env file located in the current directory. You can specify a different file using the chainchat --dotenv option.

OpenAI Compatible Models

You can use any OpenAI compatible model with ChainChat. For example to use xAI Grok put your XAI_API_KEY in your .env file and alias it to OPENAI_API_KEY:

$ chainchat --alias-env OPENAI_API_KEY XAI_API_KEY chat --tool read_file --prompt "Read and summarize the file ./LICENSE.txt" open-ai --model-name grok-beta --openai-api-base https://api.x.ai/v1
I am reading the file ./LICENSE.txt to summarize its contents.
