When to pick which
Input pricing is identical at $1.25 per million. Output is $10 on both, so this is a capabilities decision, not a price one. Gemini 2.5 Pro offers a 1M-token context window against GPT-5.1's 400K and superior native multimodality across video, audio, and images. GPT-5.1 is generally the stronger pure-text reasoner and coder, with adjustable reasoning effort and more mature function calling. Choose Gemini for long-context RAG and multimodal pipelines. Choose GPT-5.1 for agentic coding, structured output, and workloads where per-step reliability in tool use matters most.
