- Introducing our Model Router, get the most accurate model for the task at the cheapest price. Customers using the router are seeing up to 30% lower token costs with little to no change in overall accuracy.
- Stagehand 3.7 is out. Here's what shipped last week: - Control where your agent can navigate to domain allowlisting/denylisting - CUA support for Gemini 3.5 Flash and the GPT-5.6 family (Sol, Luna, Terra) - Various bug fixes & patches pnpm add @browserbasehq/stagehand@latest
- Gemini 3.5 Flash + CUA is impressive: on our benchmarks, it performs similarly to frontier models while being on average ~80% cheaper. It's a reliable model for powering browser agents that balance speed and accuracy on real-world tasks.
