OCR-4-0 API: Endpoint & Pricing

OCR-4-0 provides API OCR on LLM.API so scans and screenshots become structured, usable text.

Start Using API

What is OCR-4-0?

OCR-4-0 is an OCR-oriented model on LLM.API (`mistral-ocr-4-0`). OCR model by Mistral. It takes document, image and produces text so document workflows can digitize content before LLM analysis.

Can you self-host OCR-4-0?

No. We found no public weights for OCR-4-0 on Hugging Face, so there is nothing to download, quantize or serve on your own GPUs: no VRAM budget, no vLLM or GGUF build to plan for. The only way to run it is over an API.

Skip the deploy — use LLM.API as your endpoint

No GPUs, no quantization trade-offs. Same model, OpenAI-compatible, with custom volume discounts on request.

ERRORS

Errors & fallback routing

Code	What it means	What to do
`401`	Missing or invalid API key.	Send `Authorization: Bearer YOUR_LLMAPI_KEY` and check the key is active.
`429`	Rate limited, or the upstream provider is throttling the request.	Back off and retry with jitter; the gateway also retries the request on another provider where one is available.
`5xx`	Upstream provider error or timeout.	Retry; fallback routing sends the retry to the next healthy provider for this model.

When a provider fails or throttles, the request is routed to the next provider serving this model — the ones listed in the providers table above.

Best workloadsLLM.API features

What the model is good at.

Image OCR
Extracts text from photos, screenshots, and camera captures. Reflects OCR positioning for this endpoint.
Layout awareness
Handles multi-column and mixed layout documents better than naive OCR. Reflects OCR positioning for this endpoint.
Data capture
Feeds RPA and back-office pipelines that digitize forms and invoices. Grounded in the model's ocr role rather than generic chat claims.
Document text extraction
Reads printed and scanned pages into machine-usable text. Relevant for `mistral-ocr-4-0` workloads on LLM.API.
Annotation workflows
Supports annotated-page pricing paths when available from the provider. Grounded in the model's ocr role rather than generic chat claims.

LLM API rating for OCR-4-0

★ 2.5/ 5.0LLM API rating
50% production adoption · 30% category benchmark · 20% tooling & valueEstimated from published specs

2.5Production adoptionNot yet tracked — no public usage data for this release

How is this rating calculated?

Every model gets a separate 1.0–5.0 score for each category it can be used in, so a model can rate high for coding and lower for vision. The score combines three parts:

Production adoption — 50%. How widely the model is actually used in production: provider traffic, LiteLLM and gateway usage, open-weight downloads and its LMArena rank. Proven, widely used models score highest.
Category benchmark — 30%. The public benchmark that matters for that category — the Artificial Analysis Intelligence Index and LMArena Elo for reasoning, LMArena coding Elo for coding, image and document support plus vision Elo for vision, tool and JSON support for function calling, measured speed for voice.
Tooling & value — 20%. Context window, support for tools, structured outputs and streaming, and price compared with the category median.

Scores of 4.0 and above are shown in green, 3.0–3.9 in yellow, below 3.0 in red. When a model has no public data for a part, it gets a neutral value instead of an invented number.

A “Verified benchmark” mark (✓) means an independent lab — LMArena or Artificial Analysis — has actually tested that model, and the source figure is shown. Models without that mark are labelled “Estimated from published specs”: the score comes from the published context window, tool and schema support, price and adoption only, because no independent lab has tested them yet.

One exception: a brand-new top-tier model that scores very high on the independent benchmarks but has no usage history yet is rated on the benchmark (60%) and tooling & value (40%) alone, so a missing adoption figure can't hold it back. All inputs come from public sources and are refreshed weekly.

Adoption and benchmark inputs come from public sources — LMArena, Artificial Analysis Intelligence Index and published model specs. Updated weekly.

LMArena—Speed—Sources: LMArena, Artificial Analysis

Summarised from publicly published developer and community reviews of this model family. Opinions are the sources’, not LLM.API’s, and may not be specific to OCR-4-0.

Document-intelligence reviews score Mistral OCR around 4.3/5 for extraction accuracy, structured output and broad language coverage.
Practitioners highlight bounding boxes, confidence scores and JSON-schema output as the features that make it pipeline-ready.
It is framed as a developer/enterprise tool rather than an end-user document app.
