Changelog Update

Claude Opus 4.8 Now Available in the Agent Builder

🎯 What is it?

Claude Opus 4.8, Anthropic's latest and most advanced reasoning model, is now available in Dust's agent builder. Enterprise customers can select it as the underlying model when creating custom agents, giving them access to Anthropic's most capable model to date.

💡 Why is it useful?

Opus models sit at the top of Anthropic's model family — they're designed for tasks that demand deep reasoning, sustained multi-step thinking, and the highest quality outputs. As each new version ships, it builds on the last with improved performance and reliability. Opus 4.8 is no exception, and it's now within reach directly from your Dust workspace.

⚙️ How does it work?

When building or editing a custom agent in Dust, you can now select Claude Opus 4.8 as the model powering that agent. The model is not set as a default — it's a deliberate choice available to those who want the highest level of reasoning for specific, demanding use cases.

✨ Concrete Use Cases

Here's how you could use it:

Complex analysis & synthesis: Build an agent that processes lengthy, nuanced documents — legal contracts, research reports, financial filings — and produces high-quality structured summaries or recommendations.
Advanced code generation & review: Set up a coding agent that not only generates code but critically evaluates logic, identifies edge cases, and suggests architectural improvements across long codebases.

📈 Benefits for you

Access to Opus 4.8 means your most demanding workflows no longer require trade-offs between speed and quality — you can configure dedicated agents that bring the best reasoning available to bear on your hardest problems, while keeping lighter models for everyday tasks.

🚀 How to access it?

This feature is available to Enterprise customers. To get started:

Go to the Agent Builder in your Dust workspace
Create or edit a custom agent
In the model selection step, choose Claude Opus 4.8
Configure the rest of your agent as usual and deploy
