Artificial Analysis

Submit generated code solutions for grading against CritPt benchmark problems. This endpoint differs from the rest of the API. It is a **code evaluation service**, not a data retrieval endpoint. It accepts one or more code submissions and returns grading results from the CritPt evaluation server. Rate limited to **10 requests per day** per user. Only successful gradings (`200`) count toward the limit — grader error responses (`400`/`422`/`503`/`5xx`) and grader timeouts are refunded. Rate limit information is returned via `X-RateLimit-*` response headers.

Returns arena Elo rankings for image-editing models. Free tier returns model identity plus Elo and CI only; Pro adds rank, samples, pricing, release date, open_weights_url, and optional category breakdowns. **Pro+ only.** Free integrations should use [`/api/v2/media/image-editing/models/free`](#getImageEditingArenaFree) instead. Only models that hold a leaderboard rank are returned: current, first-party foundational models with at least 1,000 arena appearances. Models below the threshold, superseded versions, and third-party models are omitted rather than returned with a null rank.

Returns data for a single language model identified by its slug. Includes all pro tier list fields plus detail-only fields: evaluation token counts and omniscience/openness breakdowns. Pro and Commercial only. Free tier requests return a `403` subscription error. The per-provider breakdown (`providers` array) is **Commercial only** and omitted from Pro responses. [Contact us](https://artificialanalysis.ai/data-api#contact) to discuss Commercial access.

Returns a time series of performance metrics for the specified model, broken down by API provider. Each provider that offers this model will have its own series of data points within the requested window. The four metrics tracked per data point are: - **Output speed** — median tokens generated per second (`median_output_tokens_per_second`) - **Time to first token** — median latency before the first token is returned (`median_time_to_first_token_seconds`) - **Time to first answer token** — median time until the first answer token is available (`median_time_to_first_answer_token_seconds`) - **End-to-end response time** — median end-to-end response time in seconds (`median_end_to_end_response_time_seconds`) Use `window` to control how far back the data goes and `interval` to control the granularity (e.g. `window=90d&interval=weekly` returns ~13 weekly data points per provider). **Commercial only.** Free and Pro tier requests return a `403` subscription error. [Contact us](https://artificialanalysis.ai/data-api#contact) to discuss Commercial access.

Detail-only fields (evaluation token counts, omniscience/openness breakdowns, providers) are available on `/api/v2/language/models/{slug}`. **Pro+ only.** Free integrations should use [`/api/v2/language/models/free`](#getLanguageModelsFree) instead.

Returns individual measurement records for the specified provider, including per-request output speed, time to first token, time to first answer token, estimated end-to-end response time, and success status. Results are grouped by model within the provider. **Commercial tier only.** Your API key must have explicit grants for the requested provider. If you are interested in accessing this endpoint, please [contact us](https://artificialanalysis.ai/data-api#contact) to discuss Commercial access.

Returns performance time series for each model offered by the specified provider, looking back from today by the specified window. This is the inverse of the model performance endpoint — here you pick a provider and see how each of their models has performed over time. **Commercial only.** Free and Pro tier requests return a `403` subscription error.
