At AWS, we believe AI builders should be able to choose the right model for every task, trust their agents in production, and see clearly what their AI workloads cost. That belief guides how we invest across our portfolio. Amazon Bedrock gives you access to leading models and the tools to build and scale AI applications securely.
We extend this foundation with Amazon Bedrock AgentCore, which provides the platform to build, connect, and optimize agents using any model and any framework. That includes Strands, our open source agent development toolkit. Together, they take you from first prototype to production.
As agents move into core business workflows, the bar rises. You need the flexibility to use different models as tasks, budgets, and latency targets change. When a primary model is throttled or unreachable, your agents must keep working. They also must act within limits you set and return output other software can use as is.
Their answers must stay grounded in sources you allow, and their cost must hold up at high volume.
What we shipped in October addresses each of these needs. New models help you match each task to the right price and speed, from high-volume subagents to real-time voice. Amazon Bedrock and AgentCore updates keep agents available, hold them to the processes you define, and help you trust what they return. New pricing and cost reporting make spend more predictable.
Strands adds new ways to build, contain, and test agents.
Run fast, low-cost subagents. Claude Haiku 5.5 is built for subagents and high-volume, cost-sensitive work. According to Anthropic, it is the most capable Haiku yet and costs around 75 percent less than Claude Haiku 4.5 for most tasks. It is also the first Haiku with effort controls, so you can tune cost against intelligence for each task.
In a multi-agent setup, a model such as Claude Opus 5.5 can plan the work and hand well-defined coding, tool use, and browser automation tasks to Haiku. This keeps running many agents in parallel affordable.
Get near-flagship results at a lower price. OpenAI GPT-6.1 Terra is now generally available on Amazon Bedrock. On OpenAI’s Agents’ Last Exam evaluation, it performed on par with GPT-6 Astra and completed tasks more than three times faster than GPT-6 Astra and GPT-6.1 Sol. Its input and output token prices are at least 50 percent lower than those of GPT-6.1 Sol and GPT-5.6 Terra.
It accepts text and images with up to 1 million input tokens, which suits drafting proposals, interpreting technical drawings, and building agents that work across business systems. For latency-sensitive work such as real-time coding assistants, GPT-6.1 Sol now also offers Ultrafast mode.
Build voice agents that reason in real time. Amazon Nova 2.5 Sonic, our latest speech-to-speech model, improves reasoning, instruction following, and tool-calling accuracy, with lower latency at the same price as Amazon Nova 2 Sonic. A customer service agent can now look up an order, check return eligibility, and start a return in a single conversation.
Pick specialized models for coding and video. GLM 5.3 by Z.ai is an open-weight model for agentic coding and long-horizon software engineering, with a 1-million-token context window and prompt caching, available to eligible enterprise customers. TwelveLabs Pegasus 1.5 turns entire videos into structured, time-coded metadata.
It reads visuals, audio, and on-screen text in a single pass, with no separate ingestion pipeline.
