Chat Smith has added Gemini 3.5 Flash to its model lineup — Google DeepMind’s first Gemini 3.5 model, launched at Google I/O on May 19, 2026, delivering frontier-level intelligence at 4x the speed of comparable models, available now for all Chat Smith Pro users at no extra cost.
Gemini 3.5 Flash is the first model in the new Gemini 3.5 family and the strongest agentic and coding model the Flash tier has ever shipped. Unlike previous Flash releases that made explicit quality trade-offs for speed, 3.5 Flash claims frontier-level intelligence at Flash-tier latency — and backs it up by outperforming Gemini 3.1 Pro on coding and agentic benchmarks. It is now the default model powering the Gemini app and AI Mode in Google Search.
What makes Gemini 3.5 Flash stand out
4x faster than other frontier models. Gemini 3.5 Flash runs at roughly four times the output token speed of comparable frontier models. Inside Google’s Antigravity 2.0 agent harness the speedup reaches 12x. This makes it practical for high-volume agentic pipelines, long document processing, and real-time coding assistance where latency directly impacts usability.
Beats Gemini 3.1 Pro on coding and agentic benchmarks. Gemini 3.5 Flash scores 76.2% on Terminal-Bench 2.1, surpassing Gemini 3.1 Pro’s 70.3%. It leads the MCP Atlas tool-use benchmark at 83.6% and scores 1,656 Elo on GDPval-AA, the real-world agentic task metric. On CharXiv Reasoning it reaches 84.2%, covering multimodal chart and image understanding.
True multimodal input with a 1M-token context window. The model accepts text, image, audio, video, and PDF inputs across a 1,048,576-token context window — enough to process hundreds of pages of documents or large codebases in a single pass. Dynamic thinking is on by default, with four configurable levels (minimal, low, medium, high) for fine-grained cost and performance control.
Built for agentic workflows and tool use. Gemini 3.5 Flash natively supports function calling, structured output, search-as-a-tool, and code execution. Its 90% cache discount on repeated input tokens makes it particularly cost-efficient for agent loops that re-send the same system prompt and tool definitions on every call.
Included in Chat Smith Pro — no extra cost
Gemini 3.5 Flash is available immediately to all Chat Smith Pro subscribers. No upgrade, no additional charge — open the model picker and select Gemini 3.5 Flash to get started.
Chat Smith’s goal is to bring the best available AI models into one place, so users can choose the right tool for each task without switching platforms.
