Detailed analysis
Context Length
Winner: Gemini 2.5 Pro Preview 06-05Gemini 2.5 Pro Preview 06-05 supports 1,048,576 tokens while GPT-5 Mini supports 400,000 tokens. This gives Gemini a clear advantage for extremely long inputs. GPT-5 Mini is described as handling very large contexts efficiently despite the smaller window.
Pricing
Winner: GPT-5 MiniGPT-5 Mini costs $2 per million tokens compared to $10 for Gemini 2.5 Pro Preview 06-05. The lower price makes GPT-5 Mini more economical for high-volume use. No other cost factors are provided.
Speed
Winner: GPT-5 MiniGPT-5 Mini lists an output speed of 99.68 tokens per second. Gemini 2.5 Pro Preview 06-05 has no speed number but notes slower responses at maximum context sizes. This favors GPT-5 Mini for speed-critical workloads.
Multimodal Integration
Winner: Gemini 2.5 Pro Preview 06-05Gemini 2.5 Pro Preview 06-05 integrates text, image, audio and files with native large file support. GPT-5 Mini integrates text, image, and file inputs but does not mention audio. Gemini therefore offers broader modality coverage.
