Open-source evaluation platform for voice and chat AI agents
Register, organize, monitor and version conversational agents across different model and telephony providers from one place, so switching a provider doesn't mean rebuilding your evaluation setup.
Replay realistic voice and chat interactions with pre-built personas and scenarios, and simulate edge cases that are difficult or expensive to reproduce manually.
Score agents with standardized metrics and compare runs side by side, making it clear whether a prompt, model or pipeline change actually improved performance.
Access 100+ LLM, speech-to-text and text-to-speech models plus telephony provider integrations, so evaluations reflect your real production stack.

Google's rapid prototyping IDE and developer API workbench for building multimodal applications with Gemini models.
Allows developers to drop hours of video, multi-track audio files, high-resolution images, entire codebases, and multi-hundred-page PDFs directly into the prompt window with up to 1,000,000 tokens of shared context.
Provides direct access to Google's frontier reasoning and agentic models with granular controls over thinking tokens, temperature, function declarations, and strict JSON schema output validation.
Includes a dedicated `/live` studio interface for testing sub-second, bidirectional voice and screen/camera interactions powered by `gemini-3.8-live`, `gemini-3.8-live-extended-thinking`, and `gemini-3.5-live-translate-preview`.
Connects model responses to live Google Search results and Google Maps geospatial data with a single toggle, including 5,000 free grounded requests per month on Paid tiers before $14/1,000-query metering.
