404oopsandClaude Opus 5.5 eef8258539 fix(ai-ocr): sync OCR models and prices, route by model, cap input size
Model sync against Mistral's listing, docs and a live call per id:
mistral-ocr-latest now serves OCR 4.1, so the catalog pins it (with
mistral-ocr-4 and the retired-but-redirected 2503) to mistral-ocr-4-1,
adds mistral-ocr-4-0 and OCR 3 (mistral-ocr-2512 / -3 / -3-0), and
rejects the retired mistral-ocr-2505 before any upstream call. Mistral
usage is metered per model at vendor rates: $4/1000 pages for OCR 4.x
with $5 annotations, $2 and $3 for OCR 3, replacing the flat $1 and $3.

Textract now calls DetectDocumentText instead of AnalyzeDocument with
LAYOUT. The layout feature cost $4/1000 pages while we billed the
$1.50 detect rate, and it only added text-less LAYOUT_* blocks that put
blank lines into img2txt output. Multi-page PDFs and unsupported
formats become a 400 that names Mistral as the alternative.

Request shape: a model name alone now selects its provider, so calls
differ only by model; an explicit provider still picks its default and
must agree with the model. Mistral options gain tableFormat,
extractHeader, extractFooter and documentAnnotationPrompt; annotation
formats accept the REST (json_schema.schema) or SDK
(jsonSchema.schemaDefinition) spelling and are validated before
billing. Non-image documents such as DOCX go as document_url.

Response shape: both providers return model, text and blocks with a
0-based page; Mistral also returns document_annotation, which was
billed but dropped. img2txt resolves to that annotation when
documentAnnotationFormat is set and to the text otherwise; the return
is a string for every model, so normalize has no effect on it.

Input size: OCR input is capped at the provider limit (10 MB Textract,
50 MB Mistral), and web inputs in loadFileInput are streamed under the
cap instead of buffered whole, which also bounds speech2txt URLs.

Docs: img2txt models, options, input limits, return value and errors;
OCR limits in the quotas page.
