coding agent

DeepSeek's Harness team has open-sourced dsh-superagent, a research prototype that receives development requests through GitHub and optionally Feishu. It works on each request in a separate session and returns results such as pull requests to the original conversation, according to TechNode.

Factory released Droid 1.0, a model-independent coding agent harness that makes programmatic tool calling the default. On Factory's own Terminal-Bench 4 runs, Droid scores 65.2% with Claude Opus 5.5 at $4.73 per passed task.

Microsoft has released FrogNano-4B-2609, a repository-level coding agent derived from Qwen3.5-4B and published under Apache 2.0 with open weights. Microsoft says it was post-trained only with reinforcement learning on about 1,500 synthetic software-engineering tasks, with no stronger-model trajectories. It is evaluated at roughly 131K tokens of context.

Cline's v4.1.11 update adds inline image generation for supported models and fixes a code actions bug that broke on VS Code 1.134. The release also expands the model catalog with eight new providers including AMD, Arcee, and RunInfra.

Meta has released Muse Code, its first AI coding agent, built to work with the new Muse Spark 1.2 model. The beta tool undercuts rivals Anthropic and OpenAI on price rather than raw capability, according to Meta AI chief Alexandr Wang.

xAI has released Grok Build, a coding agent and CLI tool positioned to compete with Anthropic's Claude Code and other AI coding assistants. The early beta is available exclusively to SuperGrok Heavy subscribers at $300 per month.
