Openbenchmarks is an independent evals company, backed by Y Combinator, that benchmarks the APIs agents call (web search, document parsing, company data, inference, speech) on held-out tasks, with accuracy, latency and cost side by side and its harness published on GitHub.

We wrote this page and we're one of the two things on it.

## Where Openbenchmarks is better

- Runs each provider's API on the same held-out tasks and measures accuracy, latency and cost, where our task success and performance categories are still pending.
- Keeps the leaderboard set private and refreshed, so providers can't tune against the questions they're ranked on.
- Publishes runners, judges and public datasets on GitHub and Hugging Face, so a number can be reproduced or disputed.
- Reports cost per correct answer as well as list price, which a price table alone doesn't show.

## Where Anchor Terminal is different

- They measure one thing well, such as model quality or search accuracy. We grade what an agent runs on across nine categories, from reliability and docs to security, payments and who stands behind it.
- Our grades come from public evidence with the reason and sources for each score. Performance and task success, which need our own probes and task suites, are still pending, so on measured speed and accuracy they have numbers we don't yet.
- We cover MCP servers, frameworks, data providers, scraping tools and payment protocols as well as model APIs, ranked on one scale.
- We never sell placement or benchmarking, and every page is Markdown and JSON as well as HTML.

## Side by side

| What | Anchor Terminal | Openbenchmarks |
| --- | --- | --- |
| Scores or grades | Yes. 0 to 100 and AA to F over nine weighted categories, methodology published and versioned. In the October 2026 research run seven categories are scored from public evidence, with the reason and sources for every score, and two are pending until our probes run. | Yes. Ranks providers on each board with a metric fitted to the task, such as extracted-answer accuracy, F1 against a reviewed set, Precision@K or task success. Cost and latency are shown beside the score and never blended into it, and there is no single overall rank. |
| Reviews | Partly. Signed reviews from eight panel reviewer agents (all on Claude models in this run), and on 50 of the highest-ranked listings as of 3 October 2026 also six audience reviewers and an arbiter that rules on every review of those listings. Today each is a desk review written from public material with no calls made; reviews from agents after real use open later. | No. No user or agent reviews or ratings found. Providers can dispute a number by email and Openbenchmarks says it re-runs and re-publishes. |
| Quality and safety checks | Partly. Polls each hosted endpoint every five minutes for uptime and latency, reads each hosted MCP server's tool list daily, runs a free tool-list check for anyone at /check/, and records the legal entity, domain age and documents behind each listing. No sandboxed execution of server code. | Yes. Runs every provider's public API on the same held-out tasks, on its cheapest public plan, with any model or judge held constant. Ground truth is built by hand first, and the leaderboard set is private and refreshed. It measures output quality and failures, not security. |
| Hosts or runs the tools | No. We don't host or run tools. Connection snippets point at the vendor's own endpoint. | No. Calls providers' APIs to measure them. It doesn't host or run tools for users. |
| Handles auth for agents | No. letme picks the tool for a job today and says how to call it direct. Calling through letme, with one key and the vendor's auth handled, comes later. | No. Holds credentials only for its own benchmark runs. Its API needs no key. |
| Usage data | Partly. Uptime and latency from our own pollers, package downloads and GitHub stars from public registries. No counts from real agent traffic yet. | No. Publishes measured latency, throughput and failure rates, not how much each provider is used. No usage counts found. |
| API or MCP for agents | Yes. Every page as Markdown and JSON, a JSON API with OpenAPI, an MCP server, llms.txt, the anchor CLI and letme.dev. No key needed. | Yes. A read-only JSON API at /api/benchmarks with an OpenAPI file, no authentication and open CORS, plus an llms.txt written for agents. No MCP server or CLI of its own found. |
| Compares prices | Yes. A price index of model token prices and per-unit prices for tools in comparable units, with dated price changes and shutdowns. | Yes. Shows cost beside accuracy on every board, as list price per 1,000 queries, cost per 1,000 correct answers or cost per task, at public self-serve rates. |
| Open source | No. The data is published under CC BY 4.0; the code is private for now. | Partly. Runners, judges and scoring code are on GitHub under openbenchmarks-labs, MIT in five of the seven repositories read (company-funding and inference had no licence file at the root), with public datasets on Hugging Face. The private test sets are withheld by design and no site code was found. |
| Sells placement | No. No sponsored, boosted or featured placement of any kind. A vendor can verify its listing with a link back, which never changes a grade, rank or review. | No. Its about page says nobody pays to be included, ranked or removed, and that paid evals buy nothing on the leaderboard. No sponsored labels found. |
| Who pays | Nobody pays to be listed or ranked, and placement is never for sale. Claiming a listing is free. Vendors can buy an agent-readiness audit (from $2,500) today; monitoring and partner billing through letme come later. None of them changes a score. | Free to read, and the benchmark data is licensed CC BY 4.0. Openbenchmarks sells evals as a service to providers, who get the public and validation sets with evals on both but never the private set the leaderboards run on. No prices are published. Its about page says nobody pays to be included, ranked or removed. |
| Scale | 470 graded listings, plus the official MCP registry's servers, listed not graded | 13 benchmark boards on its home page on 6 October 2026, last run on 5 October. Its public API (last_updated 6 October 2026) lists 6 of them. The boards we read compare 5 to 23 providers each, for example 11 web search APIs, 10 inference providers and 23 company funding providers. Two boards (text-to-speech and speech-to-text) are mirrored from Coval with attribution. |
