OPEN RESPONSES

Summary from the TLDR newsletter

Open Responses is an open-source spec for building multi-provider, interoperable LLM interfaces on top of the original OpenAI Responses API. It is multi-provider by default and extensible without fragmentation. Useful for real-world workflows, Open Responses can be used to build agentic systems without rewriting the stack for every model. Examples of projects built with Open Responses are available in the thread.
