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 API contracts indexed on the APIs.io network, including Check Cache API, Criteria API, Datasets API, and 7 more. Tagged areas include Artificial Intelligence, LLM, Fine-Tuning, Distillation, and Inference.

The OpenPipe catalog on APIs.io includes 1 Spectral governance ruleset.

OpenPipe’s developer surface includes authentication, documentation, and 11 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
