Codex Parallel Capacity Noticeably Tightened
petrusenko_max · x · 2026-07-11
The author notes that the $200/month Codex plan previously offered ample capacity for multi-agent parallel execution, rarely hitting limits even when running 10+ agents simultaneously. However, under GPT 5.6 Sol, this headroom has shrunk significantly; users now frequently encounter hard limits when running just 1–2 agents.
The core takeaway: available capacity for high-concurrency coding workflows has seen a notable regression, which is highly unfavorable for power users relying on large-scale parallelism.
