What’s new in Claude Opus 4.5

Enhanced reasoning and coding across complex tasks, including software development, data analysis and multi-step problem solving, with leading performance on coding and agent benchmarks.
Stronger agentic capabilities, enabling agents to work more effectively with spreadsheets, documents and other tools as part of end-to-end workflows.
Improved context handling and memory for long-running, multi-step interactions where consistency and reliability are critical.

Benefits for Zeaware Avalon customers

More reliable performance and flexibility through upgraded backend model support within Avalon’s governed, enterprise-ready framework.
Opportunities for more advanced automation using Opus 4.5’s improved planning, tool-use and long-horizon task handling.

Getting started

Claude Opus 4.5 can be added within the service or model settings in your Avalon environment. To explore the new capability, you can:

Re-run existing workflow tests and compare results when switching to Opus 4.5.
Use more complex, multi-step tasks or agent flows that benefit from stronger reasoning and tool-use.
Review workflows that previously required manual oversight, as Opus 4.5 may reduce orchestration complexity.

What’s next

Our roadmap includes exposing additional Claude Opus 4.5-powered features across Avalon, including enhanced code-aware agents, richer analysis workflows and more capable autonomous and semi-autonomous agent interactions. We will share updates as these capabilities become available.
