The big idea
Different models are best at different things. GPT-5 leads on multimodal and tool use. Claude Opus 4.7 leads on long-context coding and writing. Gemini leads on giant context windows and Google integration. Open models (Llama, DeepSeek) lead on price and privacy. Knowing the rough strengths saves you from forcing the wrong tool.
Some examples
- Long essay or research paper analysis (50+ pages of context): Claude or Gemini — bigger context windows, better recall.
- Code generation across a whole repo: Claude Opus 4.7, GPT-5 with Codex, or Cursor's models — all close, all good.
- Quick voice conversations + image understanding: GPT-4o/5 — most polished multimodal experience.
- Research with live web sources: Perplexity, ChatGPT search, or Claude with web search — all do real-time grounding.
