Specification and compliance-testing tools for interoperable language-model APIs, including streaming responses and tool calls.
Open Responses defines a shared interface for applications that use language models from multiple providers. Its specification covers structured requests and responses, streaming events and tool invocation, including loops where a model receives tool results and continues. The repository supplies an OpenAPI schema, dated releases and documentation, plus web and command-line compliance tests for checking implementations.
