Gemini 3.1 Pro Preview vs GPT-5.4 Mini
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 3.1 Pro Preview if you need
- ✓Lower cost at $4.5 per 1M tokens for budget-conscious large-scale processing
- ✓Faster output speed of 170.35 t/s to reduce latency in high-volume tasks
- ✓Flexible multimodal workflows focused on files, images, and text for document-heavy use
- ✓Sufficient 400k context when maximum scale is not required
Choose GPT-5.4 Mini if you need
- ✓Higher intelligence index of 46.5 for more capable complex reasoning
- ✓Enormous 1M token context for large-scale document analysis
- ✓Native support across audio, image, video, and text with strong modality integration
- ✓Preview access to cutting-edge multimodal performance despite higher cost
Verdict
Gemini 3.1 Pro Preview leads in intelligence (46.5 vs 40) and maximum context (1M tokens), making it stronger for complex multimodal integration including audio and video. GPT-5.4 Mini wins on speed (170.35 t/s vs 122.47 t/s) and price ($4.5 vs $12 per 1M tokens) while still offering a very large 400k context and native file/image/text support. The choice hinges on whether raw capability or efficiency matters more for document-heavy multimodal workflows.
