Am I OpenAI Compatible: Tool & Docs for Unified API Signatures

A Reddit user has released a tool and documentation page called 'Am I OpenAI compatible' that maps which major open-source AI projects adhere to OpenAI's API signatures. The project was motivated by inconsistencies between engines like vLLM and llama.cpp, which often implement the same endpoint differently.
Key Details
The tool catalogs both official and unofficial API signatures for each project. For models where OpenAI compatibility gaps exist, it introduces 'ht-compatibility' as an inherited standard. The developer plans to add optional Anthropic-compatible signatures and other extensions.
Two resources are available:
- GitHub repository: heiervang-technologies/am-i-openai-compatible
- Documentation site: ReadTheDocs
The developer notes the tool is useful for plugging LLM and other AI endpoints into apps, or for building proxy/middleware layers. Developers creating their own API interfaces will also benefit from the documented signatures, making agent integration easier.
Who It's For
Developers working with multiple open-source inference engines who need a reliable reference for API compatibility, or anyone building middleware or agent systems that consume multiple backends.
