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 Artificial Intelligence, LLM, Fine-Tuning, Distillation, and Inference.

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

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/openpipe: open an issue to ask a question, or submit a pull request to add artifacts.
