Gemini 3.5

Definition

Google introduced Gemini 3.5 in May 2026, beginning with Gemini 3.5 Flash, which Google positions for fast agentic workflows. Google also announced Gemini 3.5 Pro as part of the same family.

What is Gemini 3.5?

Gemini 3.5 is Google's 2026 model generation introduced with Gemini 3.5 Flash in May 2026. Google positioned the Flash model around fast, agentic workflows and also announced a Gemini 3.5 Pro line.

Why Flash and Pro differ

Flash models are designed for higher-throughput and latency-sensitive workloads. Pro models target harder reasoning and professional tasks. The distinction reflects a broader industry trend toward model portfolios rather than one model serving every request.

Where to check the current lineup

Gemini versions change quickly and Wikipedia can lag first-party announcements. Google's model pages and developer documentation should therefore be treated as the authoritative source for current availability, context limits and pricing.
