Amazon Web Services Announces October 2026 Innovations for Artificial Intelligence Developers

Amazon Web Services (AWS) has announced new artificial intelligence features, model updates, and tools introduced in October 2026 to help artificial intelligence developers select models, run agents securely, and view workload costs.

Claude Haiku 5.5 has been added to the Amazon Bedrock platform, developed for high-volume and cost-sensitive sub-agent tasks, while the OpenAI GPT-6.1 Terra model has also been made generally available. Additionally, the Amazon Nova 2.5 Sonic speech model, GLM 5.3 developed by Z.ai, and the TwelveLabs Pegasus 1.5 video processing model have been integrated into the platform.

Amazon Bedrock AgentCore version 1.0 has become generally available, with AgentCore Gateway beginning to support model fallback mechanisms and AWS Step Functions workflows. Structured output support for Claude models and web search domain filtering with the OpenAI Responses API have been introduced.

Within the Strands toolset, Bidi Agents for two-way voice agents, the native sandbox Strands Box, Strands Evals for red teaming tests, and the decision model Strands Decider have been added, enhancing cost reduction and security features.
