Public story · 2026-02-17 · source-backed
GitHub paused its GPT-5.3-Codex rollout after P99 latency jumped from 200ms to 800ms. The model's increased GPU memory usage reduced concurrent request capacity, but the 5% canary deployment failed to surface the issue — bottlenecks only appeared at higher concurrency. GitHub rolled back to GPT-5.0 with no restart date announced. The timing was ironic: this happened the same day GitHub launched Agentic Workflows listing Codex as a supported agent engine.
