What Makes Gemini 3.5 Pro Different

Google skipped 3.4 and went straight to 3.5 — a signal of how much this model improves on its predecessor.

Speed icon

Sub-200ms Response Speed

Gemini 3.5 Pro uses advanced distillation and sparsity techniques to compress frontier-model capability into a fast, efficient architecture. Many queries return in under 200ms — faster than any comparable model at this quality level.

Code icon

Frontier Coding Ability

Developers report single-prompt generation of complete, working applications — a Windows-style web OS, a Minecraft clone, a full MMORPG with 4,100 lines of code. The coding benchmark puts it at 92% of GPT-5.5.

Cost icon

1/15 the Cost of GPT-5.5

Leaked pricing: $0.25 per million input tokens, $2 per million output tokens. That's 15–20x cheaper than GPT-5.5 for comparable output quality — making it the most cost-efficient frontier model available.

Multimodal icon

Multimodal Understanding

Gemini 3.5 Pro handles text, images, and complex multi-step reasoning in a single model. Ask it to analyze a chart, describe an image, or reason through a multi-part problem — it handles all of it.
