Background & analysis

On October 20, 2026, a developer published on DEV Community an account of how their team splits work across several models. According to the post, the team stopped relying on a single model for everything months earlier for two reasons: their subscriptions kept hitting their limits, and a model that does all the work also ends up checking its own output, which the author describes as the task models handle worst.

The team therefore divided responsibilities. Claude handles planning and checking, Grok is pointed at whatever Claude has just written to find faults, and Codex builds the large pieces. Starting this week, Tīrtha, the team's own router, takes over routine building work.

The developer also released a ledger covering September 25 to October 17. Over that period, Grok raised 519 issues. After human review, 309 were judged valid, of which 207 were not present in Claude's first drafts and 59 were classified as critical. The median cost of a single review was $0.021.

The public account ends with this division of labor and the accompanying figures; the material does not say whether the setup was changed afterward.
