All three models have made significant leaps in reasoning, but with different approaches:

Claude Opus 4.7

Claude Opus 4.7 represents a 13% improvement over its predecessor on a 93-task coding benchmark. It excels at:

• Complex multi-step workflows — Can handle tasks that previously would stop previous models dead in their tracks
• Implicit need detection — The first model to pass Anthropic's implicit-need tests
• Creative reasoning — Particularly strong on CursorBench (70% vs 58% for Opus 4.6) Tool error recovery — Continues executing through tool failures that used to halt progress

GPT-4.1 / GPT-5 Series

OpenAI's flagship models now include the GPT-5 family, with GPT-5.5 positioned as the premier offering:

• Extended thinking — Built-in reasoning mode for complex problems
• Web search integration — Real-time information access ($10/1K calls)
• Code execution — Native code interpreter capabilities Function calling — Excellent structured output generation

Gemini 2.5 Pro

Google's Gemini 2.5 Pro (now evolving into Gemini 3 series) offers:

• Massive context window — Up to 2 million tokens for large document analysis
• Native Google integration — Seamless connection to Search, Maps, Workspace, and YouTube
• Strong multimodal reasoning — Particularly effective at video and image understanding Cost efficiency — Generally cheaper at both input and output compared to competitors

💻 Coding Performance

For developers, coding capability is often the deciding factor. Here's how they stack up:

Real-world feedback: Rakuten AI reports that Claude Sonnet 4.6 produced "the best iOS code we've tested" with better spec compliance and architecture than competing models. Meanwhile, Notion Agent found Opus 4.7's reliability jump made it "feel like a true teammate" for complex workflows.
