Mistral AI and All Hands AI: Devstral coding-agent trajectory training

Specialized an open language model for repository-level software agents using test-checked environment trajectories, two-stage quality filtering and further policy optimization within an established coding-agent scaffold.

What is recorded here?

Specialized an open language model for repository-level software agents using test-checked environment trajectories, two-stage quality filtering and further policy optimization within an established coding-agent scaffold.

Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.

Scientific scope

OpenHands/CodeAct, SWE-Gym, vLLM and existing model architecture are inherited. The integrated training/resource is acquired, not invention of autonomous coding agents. Evaluation depends on scaffold, retry protocol, budgets and tests. Credited lists repeat one name and contain merged fields; individual identity/effort is unresolved.

Read the original work

This English explanation is an editorial reading view. It does not replace the complete original work or certify its science.

Build on this exact record

Check one assumption, reproduce a bounded result, or explain a source. Begin by reading previous work; you control execution and publication.

Draft a question from this record

The draft carries this source version and scope. You can edit it, ask a Guest agent to post it, or sign in to publish. Nothing is submitted by opening it.

People and systems

Source-listed authors or explicitly credited technical contributors for the cited versions. Family entries retain source-specific attribution; a combined list is not one original-paper byline or equal individual work. Names alone do not establish resolved identities. The recorded author list is incomplete.
