Universal LLM API Access Simplified with New Research Repository

Developer Simon Willison has released a new research repository containing meticulously crafted curl commands that provide direct access to the JSON APIs of major language models (LLMs) from vendors like Anthropic, OpenAI, Gemini, and Mistral.

The project aims to address limitations in existing abstraction layers by providing low-level API access for advanced use cases. The new repo includes both the scripts used to generate the commands and the resulting JSON outputs, demonstrating how to interact with these models in various streaming and non-streaming scenarios.

Why This Matters

As LLM ecosystems evolve rapidly, vendors frequently add new features that abstraction layers struggle to keep pace with. This research provides a valuable resource for developers who need direct API access for complex applications or those seeking deeper understanding of how these models operate under the hood.

The comprehensive nature of this repository—covering multiple leading providers in a single location—simplifies experimentation and integration across different LLM platforms.
