tool calling

Amazon Web Services released technical guidance for migrating text agents to voice assistants using Amazon Nova 2 Sonic, a native speech-to-speech model that combines automatic speech recognition, reasoning, tool calling, and text-to-speech in a single bidirectional streaming interface. The model supports asynchronous tool calling and built-in voice activity detection for handling interruptions.

Poolside has released Laguna XS.2, the second-generation model in its XS size class for agentic coding workflows. The model offers 128K context window, up to 8K output tokens, and is quantized to fp8 for efficiency, available free via OpenRouter.
