What is Models offered?

Models offered is the catalogue a provider exposes through its API, and it decides how freely you can change model without rewriting integrations. The range runs from narrow to wide. AI21 Labs lists Jamba Large, Jamba Mini and Jamba 3B, while Aleph Alpha lists two Pharia variants. Anthropic serves four Claude models. AI/ML API covers far more, spanning text, image and video families, and Amazon Web Services offers a broad catalogue through Bedrock that also includes Custom Model Import for your own weights. Breadth helps if you plan to route prompts to the cheapest capable model.
