Head-to-head notes
Claude Sonnet 4
Anthropic · 2025
Strengths: Excellent quality-to-price ratio. Default pick for production coding agents.
Watch out: Loses to Opus on deep reasoning and creative nuance.
GPT-4o
OpenAI · 2024
Strengths: Solid all-rounder with fast voice and image capabilities. Huge ecosystem of tooling.
Watch out: Reasoning behind Claude Opus / o1. Writing feels more generic.
Gemini 1.5 Pro
Google · 2024
Strengths: 2M-token context window — unmatched for feeding entire codebases or long videos.
Watch out: Quality dips at very long contexts. Safety filters can be intrusive.
Prices are list rates per million tokens as of publication. Always verify with the provider before budgeting.
