Gemini 2.5 Pro Preview 05-06 vs GPT-4.1 Nano
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
- ✓Need native audio and video processing alongside text, images, and files
- ✓Require strong cross-modal reasoning capabilities
- ✓Want flexible file handling in a very large context window
- ✓Can accept preview-version variability for advanced multimodal tasks
Choose GPT-4.1 Nano if you need
- ✓Need the lowest output price at $0.4 per 1M tokens
- ✓Require fast output at a measured 162.07 tokens per second
- ✓Prefer a known intelligence index score of 7.3 with efficiency focus
- ✓Work primarily with images, text, and files without audio or video
Verdict
Gemini 2.5 Pro Preview 05-06 leads in native multimodal breadth with audio and video support plus strong cross-modal reasoning, while GPT-4.1 Nano leads on known speed (162.07 t/s) and dramatically lower price ($0.4 vs $10 per 1M tokens). Both deliver nearly identical 1M+ token context windows and handle images, text, and files, but Gemini's preview status introduces potential variability not reported for GPT-4.1 Nano.

Detailed analysis
Modalities
Winner: Gemini 2.5 Pro Preview 05-06Gemini 2.5 Pro Preview 05-06 natively supports text, images, audio, video, and files with strong cross-modal reasoning. GPT-4.1 Nano supports images, text, and files under its OpenAI multimodal architecture. Gemini therefore covers more input types directly from the given facts.
Pricing
Winner: GPT-4.1 NanoGPT-4.1 Nano is listed at $0.4 per 1M output tokens. Gemini 2.5 Pro Preview 05-06 is listed at $10 per 1M output tokens. The price difference is an order of magnitude in favor of GPT-4.1 Nano.
Speed & Context
Winner: GPT-4.1 NanoGPT-4.1 Nano provides a measured output speed of 162.07 t/s and a 1,047,576-token context. Gemini 2.5 Pro Preview 05-06 lists a 1,048,576-token context but no speed figure. The contexts are effectively equal while only GPT-4.1 Nano reports speed.
Performance Depth
Winner: Gemini 2.5 Pro Preview 05-06Gemini 2.5 Pro Preview 05-06 lists strong cross-modal reasoning as a strength. GPT-4.1 Nano notes that its nano size may reduce depth on complex tasks and carries performance trade-offs for efficiency. No intelligence index is given for Gemini while GPT-4.1 Nano reports 7.3.
