OpenPipe

OpenPipe is a fine-tuning and inference platform for distilling expensive frontier-LLM workloads into smaller, cheaper specialized models. Captures production traces (OpenAI and Anthropic), fine-tunes, evaluates with judges, caches results, and serves the result via OpenAI-compatible API. Also supports proxying to external models.

OpenPipe publishes 10 APIs on the APIs.io network, including Chat API, Check Cache API, Criteria API, and 7 more. Tagged areas include AI, LLM, Fine-Tuning, Distillation, and Inference.

OpenPipe’s developer surface includes authentication, documentation, and 9 more developer resources.
