Port currently only supports generic OpenAI-compatible providers. When customers need to use an Anthropic API-compatible provider (e.g. to proxy AWS Bedrock Claude models), the OpenAI chat completions path does not fully support the Anthropic Messages API schema, leading to validation and runtime failures.

A dedicated Anthropic API-compatible provider type would allow customers to correctly route requests through their chosen proxy to Anthropic/Bedrock without hitting schema incompatibilities.
