Gemini vs GPT-4: Google vs OpenAI's Flagship Models
Last updated April 19, 2026

Verdict
Gemini 1.5 Pro's 1-million-token context window is unmatched for processing entire codebases, legal documents, or long video transcripts in a single call. GPT-4o edges ahead on reasoning benchmarks and has a larger ecosystem of third-party integrations, but the gap has narrowed substantially and the better choice depends heavily on the specific use case.
