Notes

API endpoint is https://api.featherless.ai/v1.
Model IDs use the HuggingFace org/model-name format exactly as listed on huggingface.co (e.g. mistralai/Mistral-7B-Instruct-v0.3).
Featherless supports serverless (pay-per-token) access to thousands of open-weight models without provisioning dedicated GPU capacity.
Vision and embeddings are not supported through this provider; use a different provider for those capabilities.
