The question that matters: “In what situation will I regret choosing A over B after 3 months?”
Claude 3.7 Sonnet's extended thinking mode chains visible reasoning steps across a 200K context window, producing analysis of long legal or technical documents with traceable logic rather than opaque outputs.
Extended thinking lets Claude 3.7 Sonnet identify flaws in its own code plan before writing output, reducing the back-and-forth debugging cycle on complex algorithmic tasks.
Claude 3.7 Sonnet's instruction hierarchy handling makes it reliable for production workflows with detailed system prompts and complex tool call schemas, reducing prompt engineering iterations for new integrations.
Prompt testing iterates escalation logic with actual customer messages before going live. The 2M context window holds full ticket histories and knowledge bases in one API call.
Multimodal input ingests PDFs and images; Function calling outputs JSON directly into accounting software. System instructions lock the extraction schema across all documents.
You get Gemini 1.5 Flash free, 15 RPM limit, API key generation. What's locked behind the paywall: gemini 1.5 pro, higher rate limits, production ready. Good enough for solo use and evaluation.
