Introducing Gemini 3.5 Flash

ChatBotKit now supports Google's Gemini 3.5 Flash, announced at Google I/O 2026, delivering frontier-level coding and agentic performance at 4x the speed of comparable flagship models with a 1 million-token context window.

Gemini 3.5 Flash is now available on ChatBotKit. Unveiled at Google I/O 2026 on May 19, it is Google's new default model for agents and coding - a model that outperforms Gemini 3.1 Pro on coding and agentic benchmarks while running at four times the speed of comparable frontier models, often at less than half the cost. It is available across the platform today for bots, blueprints, skillsets, and direct API use.

The headline result from Gemini 3.5 Flash is a fundamental shift in the speed-quality trade-off. Tasks that previously required a slower flagship model - debugging large repositories, reasoning over extensive data, executing multi-step agentic workflows - can now run on a Flash-class model without meaningful quality degradation. Google describes it as "frontier-level intelligence at exceptional speed," and the benchmark results back that claim, particularly for coding and autonomous task execution where Gemini 3.5 Flash rivals models several tiers above its price point.

For ChatBotKit users building agentic systems, Gemini 3.5 Flash brings a model specifically tuned for complex, long-horizon task execution and parallel agentic execution loops. Its dynamic thinking is enabled by default at medium effort, which means it automatically allocates additional compute on harder problems without requiring manual configuration. This makes it a natural fit for Blueprint-driven automations and Skillset-powered agents that need to adapt their reasoning depth based on what a task actually demands.

The model supports a 1,048,576-token context window with up to 65,536 output tokens, alongside text, image, audio, and file input. That multimodal breadth combined with function calling support means agents can reason over uploaded documents, interpret visual context, and coordinate tool use within a single coherent session. Coding assistants, document analysis pipelines, and multi-step API orchestration workflows all stand to benefit from the combination of deep context handling and fast, reliable reasoning.

At $1.50 per million input tokens and $9.00 per million output tokens, Gemini 3.5 Flash sits in a pricing range that makes it genuinely practical for production-scale workloads where quality matters. The combination of frontier-level performance on coding and agents, 4x speed advantage, and competitive pricing makes it one of the strongest additions to the ChatBotKit model catalog to date.

Gemini 3.5 Flash is available now in the ChatBotKit model picker. Select it from your dashboard or reference it directly via the API to start building with Google's fastest frontier-class model.
