It works around the clock, reproducing CI failures, writing and testing fixes, and following pull requests through review without a human in the loop. Over three months it ranked second among ClickHouse contributors by authored non-merge commits, behind the company's CTO. It runs on Nerve, ClickHouse's open-source agent runtime, using Claude for implementation and Codex for review. The median merged patch changes 67 lines across three files, and 86.5% of its pull requests with a completed decision were merged. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How many pull requests has ClickHouse's autonomous AI agent GroeneAI merged? GroeneAI, ClickHouse's autonomous AI engineering agent, merged more than 3,000 pull requests between March and October 2026. By October 25, 2026 it had opened over 4,400 pull requests total, with over 3,100 merged, about 750 still open, and nearly 500 closed without merging, an 86.5% merge rate among completed decisions. _Developers tracking what AI agents can actually ship in production codebases follow milestones like this on daily.dev._ ### What AI models power ClickHouse's GroeneAI coding agent and what runtime does it use? GroeneAI uses Claude for its main worker sessions that plan and implement changes, and Codex for separate independent reviews of the approach and resulting code. It runs on Nerve, ClickHouse's open-source agent runtime, which provides persistent sessions, memory, tools, and scheduled execution across long-running tasks. _Anyone evaluating multi-model agent architectures for coding can follow real deployments like this on daily.dev._ ### How large is a typical pull request produced by an autonomous coding agent like GroeneAI? The median merged patch from GroeneAI changes 67 lines across three files. Its work includes over 1,300 merged pull requests labeled as bug fixes, a similar count for CI and tests, and roughly 150 for performance improvements, with 23 carrying the critical-bug-fix label. _Teams weighing how much autonomy to grant AI agents in their codebase can track such benchmarks on daily.dev._ ## Similar posts on daily.dev - [What ClickHouse learned from a year of coding with AI agents](https://daily.dev/posts/what-clickhouse-learned-from-a-year-of-coding-with-ai-agents-0opqjyyzh) · The New Stack · 0 upvotes · 0 comments - [Agentic coding at ClickHouse](https://daily.dev/posts/agentic-coding-at-clickhouse-ombhogfph) · ClickHouse · 1 upvotes · 0 comments - [I Am Just One Engineer Armed with AI](https://daily.dev/posts/i-am-just-one-engineer-armed-with-ai-j1vzf8tii) · RUBYLAND · 2 upvotes · 0 comments - [I Spent 1 Month Watching AI Agents Write Code in Production.
