Nothing kills a long Codex session like the account running dry halfway through. ZergRouter shows each connected Codex account's remaining weekly quota and reset date, side by side. Stale readings are clearly marked. You still choose which account to use.

Most coding agents retry. Few remember. AdaExplore, a paper from CMU, UW and Arm on GPU kernel generation, distills repeated failures into rules that carry across tasks: 1,178 failure traces became 78 reusable rules. Which failures keep coming back in your agent runs?

Done and checked aren't the same thing. Zerg is AI automation for work that has to be right. Give it a task like a code migration or a data connector. It does the work, then checks it against your tests and the real system, so you see what passed and what still needs work.
ALT How Zerg works: Map, Build, Verify, Maintain. Verified results guide the next improvement.
Zerg AI retweeted
I'm building Zerg (@zerg_ai): systems where AI agents don't just write the code, they get better at writing it.
What I post about:
- running lots of models and agents at once (harnesses, routing; ZergRouter is out)
- self-improving loops, where the hard part is the evaluator, not the optimizer
- paper breakdowns and explainer videos on agent research
Follow along for what actually works when you hand real engineering to agents, and what breaks.
60% of Codex users also use Claude Code (per Theo). A lot of that is people paying twice to get around limits. A cheaper fix for the overflow: keep Codex, point it at DeepSeek 4.1 Flash at $0.30 per 1M input tokens, and give each API key a daily budget so nothing runs away. zergrouter.com
Built in ~4 days, mostly by agents. Original launch thread ↓

Shipped ZergRouter and listed it on Tiny Startups 🚀
Run DeepSeek in Codex, with API-key budgets and quota visibility.

You can also run DeepSeek in Codex through one endpoint and give each API key a daily budget. When a key hits its budget, it stops instead of running up a bill overnight.

It's launch week, so if something breaks, send us a message - we'll fix it ASAP!
@DurableAI's key legacy module moved from JavaScript to TypeScript + React in a 21-day agent run. Model tokens cost under $500.
At Milestone 1, roughly 30% of files passed both functional and visual checks. Zerg engineers ran the harness and triage.
Passing functional tests was not the final gate. Playwright verified behavior, not DOM structure or visual fidelity. Roughly 30% of files passed both at Milestone 1. Proposed next: DOM and visual checks inside the loop, context-aware batching, parallel runs on ZergCloud.
