Smarter Routing, DeepSeek V4.1 Flash, and Expanded Free Access: The September 2026 Platform Upgrade
We rebuilt and fine-tuned our auto-routing engines across Ultra, Pro, Eco, and Free. Highlights include OpenAI's apex GPT-6 Astra leading the Uncompromising 4-Lab Frontier Quad on Ultra, DeepSeek V4.1 Flash anchoring mathematical & algorithmic logic on Pro, a settled 5-model pure MoE pool on Eco that slashes costs and active compute while boosting coding scores, and an expansion of free daily message allowances from 10 to 25.
