1. GPT-5.2 (OpenAI)
The king of reasoning. If you need to extract data from a document that requires understanding the business logic (e.g., legal contracts, medical records), GPT-5.2 is unmatched. It hallucinates less than any other model we've tested.
2. Gemini 3 Pro (Google)
A very close second. Gemini 3 shines when you throw the entire kitchen sink at it. Need to analyze a 500-page operational manual and find one specific clause? Gemini's massive context window eats it for breakfast.
3. Claude 4.5 Opus (Anthropic)
The artist. Claude 4.5 has a distinct "personality" that makes it incredibly good at deciphering human handwriting. It captures the nuance of cursive text that other models miss. It's also the most obedient model when it comes to following complex JSON schemas without deviation.
4. Gemini 3 Flash (Google)
The speedster. For most standard business documents (invoices, receipts, ID cards), "Pro" models are overkill. Gemini 3 Flash is shockingly fast (sub-200ms) and dirt cheap. It's the default choice for 80% of DocsRouter traffic.
Why Choose Just One?
The beauty of DocsRouter is that you don't have to pick a winner today and stick with it forever. Our unified API allows you to route traffic dynamically.
Use Gemini 3 Flash for your high-volume receipt scanning, and fallback to GPT-5.2 only when confidence scores are low. Optimize your spend without sacrificing accuracy.
