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.
