Gemini 2.5 Pro Preview 05-06 vs GPT-5
A side-by-side comparison of two multimodal models — real specs, pricing, strengths and weaknesses, and a clear verdict on which to choose. Kept current by our agents.
Quick verdict: which should you choose?
Choose Gemini 2.5 Pro Preview 05-06 if you need
- ✓a documented intelligence index of 15.3 and output speed of 167.38 t/s
- ✓seamless text-image-file integration without preview variability
- ✓non-preview status for more consistent behavior on complex inputs
- ✓predictable performance metrics for maximum 400k context workloads
Choose GPT-5 if you need
- ✓over 1M token context (1,048,576) for the longest inputs
- ✓native handling of text, images, audio, video and files together
- ✓strong cross-modal reasoning across more modality types
- ✓flexible file handling in a currently available preview
Verdict
Gemini 2.5 Pro Preview 05-06 leads on raw context size and breadth of native modalities including audio and video, while GPT-5 provides the only quantified intelligence index and output speed. Both models share identical $10 per million token pricing and emphasize large context windows with multimodal file handling, though GPT-5 remains hypothetical with unverified results.

Detailed analysis
Context Window
Winner: Gemini 2.5 Pro Preview 05-06Gemini 2.5 Pro Preview 05-06 offers 1,048,576 tokens versus GPT-5's 400,000 tokens. Both list very large context as a strength, yet Gemini's window is more than double the size for handling extended multimodal sequences.
Pricing
Winner: TieBoth models are priced at exactly $10 per million tokens. No cost difference exists based on the provided specifications.
Performance Metrics
Winner: GPT-5GPT-5 supplies a concrete intelligence index of 15.3 and output speed of 167.38 tokens per second. Gemini 2.5 Pro Preview 05-06 leaves both intelligence and speed unspecified.
Multimodal Capabilities
Winner: Gemini 2.5 Pro Preview 05-06Gemini supports text, images, audio, video and files with explicit cross-modal reasoning. GPT-5 focuses on native text-image-file integration within its multimodal design.
Gemini 2.5 Pro Preview 05-06
Pros
