Get instant access to 530+ models from 24 providers with extensibility at its core:

pip install llms-py

pip install llms-py --upgrade

See Install Docs for running from Docker or source.

A major change to significantly increase the available models is the switch to utilizing the same models.dev open provider and model catalogue as used and maintained by OpenCode.

llms.json provider configuration is now a superset of models.dev/api.json where its definitions are merged, allowing you to enable providers using just "enabled": true to inherit the configuration from models.dev

The switch to models.dev greatly expands the model selection to over 530 models from 24 different providers, including new support for:
