Document analysis requires precision, large context windows, and the ability to follow extraction instructions without hallucinating. Claude Sonnet 4.6 is the best for contract review and structured extraction. Gemini 3.1 Pro handles the largest documents. GPT-5.4 is strongest for structured JSON output from documents.
The shortest way to see the safest default, the lower-cost option, and the specialist pick before you read deeper.
Claude Sonnet 4.6 is the safest overall answer here when you want the strongest default instead of the lowest list price.
Switch the scoring lens to see whether the top answer changes when you care more about cost, speed, or long-document work.

Claude Sonnet 4.6 is the best for most PDF analysis — it follows extraction prompts precisely and rarely hallucinates. For very large PDFs (over 500 pages), Gemini 3.1 Pro's 2M token context window is the better choice.
Yes, with proper prompting. Claude Sonnet 4.6 and GPT-5.4 both handle financial table extraction well. Always instruct the model to only report what it directly reads, and verify key figures manually — even the best models can make arithmetic errors.
Upload the full document (or paste the text) and ask specific extraction questions. For documents under 1M tokens, Claude Sonnet 4.6 reads the whole thing at once. For longer documents, Gemini 3.1 Pro handles up to 2M tokens in a single pass.
Meta: Llama 3.1 8B Instruct is the lower-cost option to start with when you still need useful output at scale.
Gemini 3.1 Pro is the better pick when response speed matters more than maximum reasoning depth.
Claude Sonnet 4.6 leads on structured extraction accuracy and instruction following for contract analysis.
Gemini 3.1 Pro's 2M context window handles documents that exceed 1M tokens in a single pass.
GPT-5.4 produces the most reliable structured JSON output from documents with complex schemas.
Choose Claude Sonnet 4.6 for legal, financial, and compliance document review requiring high accuracy.
Choose Gemini 3.1 Pro when the document exceeds 1M tokens (full case files, large code repositories).
Choose GPT-5.4 when you need structured JSON extraction from documents for downstream data pipelines.
