Bedrock adds GLM 5.3 for approved customers and ships Nova 2.5 Sonic for voice agents

Two model additions landed on Bedrock on the same day. Z.ai's GLM 5.3 arrives with a 1 million token context and a listed price of $1.68 per million input tokens, but only for customers AWS approves. Nova 2.5 Sonic is the new speech-to-speech model, in four regions, at the same price as its predecessor, with no published benchmark. The open source Strands framework made its voice agents generally available alongside it.

Amazon's Strands Labs releases Decider 2B, an open decision model that runs locally

Strands Labs, the experimental arm of the Strands Agents project, released Strands Decider 2B on October 1, 2026. The model does not write text: it picks one of the options you give it, answers yes or no, or scores on a scale, and it attaches a confidence value to each answer. The team reports a median of 115 ms per decision on Nvidia's RTX 3090. Code, weights, training data, and scripts are public under Apache-2.0. If you build agents, this gives you a cheap local step for routing, tool checks, and guardrails.
