**OpenAI** launched **GPT-5** with a unified user experience removing manual model selection, causing initial routing and access issues for Plus users that are being addressed with fixes including restored model options and increased usage limits. **GPT-5** introduces "Priority Processing" for lower latency at higher price tiers, achieving ~750ms median time-to-first-token in some cases. Microsoft reports full Copilot adoption of **GPT-5**, and API traffic doubled within 24 hours, peaking at 2 billion tokens per minute. Early benchmarks show **GPT-5** leading in reasoning tasks like FrontierMath and LiveBench, with improvements in hallucination control and creative writing, though some models like Grok-4 and Claude-4 Sonnet Thinking outperform it in specific RL-heavy reasoning benchmarks. OpenAI also released extensive migration and feature guides but faced some rollout issues including a broken code sample and a problematic Voice Mode launch. *"Unified GPT-5" ends model pickers, pushing developers away from manual model selection.*
