Provisional pick: Claude 3.7 Sonnet — not enough sourced decision facts for OpenAI GPT-4o / o3 and Anthropic Claude 3.7 Sonnet. We don't rank on specs we can't verify.
OpenAI GPT-4o / o3 (Coding)
What works
Code execution in ChatGPT canvas allows running Python directly in the browser — test a script without switching to a terminal
Deepest ecosystem: GitHub Copilot, Cursor, Windsurf, and most IDEs default to OpenAI models first
GPT-4o occasionally produces plausible-looking code that silently fails on edge cases — benchmark scores don't always translate to production quality
Anthropic Claude 3.7 Sonnet (coding)
What works
Claude Code CLI (agentic coding) handles multi-file refactoring and repo-level tasks that ChatGPT code execution cannot
Instruction following precision on complex multi-step coding tasks — Claude is measurably less likely to ignore constraints or change function signatures
What doesn't
Smaller IDE ecosystem — GitHub Copilot defaults to OpenAI; switching to Claude requires configuration
Claude occasionally over-explains its code rationale when brevity would be preferred
Bottom line
Provisional pick: Claude 3.7 Sonnet — not enough sourced decision facts for OpenAI GPT-4o / o3 and Anthropic Claude 3.7 Sonnet.
