AI model daily brief: September 25, 2026 — Jev Router lands

The most pressing concerns are OpenAI's critical Codex outage alongside Cerebras's major disruption, while a sweeping wave of Qwen3 model retirements on October 9, 2026 forces developers to plan migrations. DeepSeek pricing continues to shift downward on most variants but includes a notable 100% increase for V4.1 Flash, so cost projections should be rechecked.
