OpenAI releases GPT-5 with native voice and real-time reasoning
GPT-5 ships with built-in voice I/O and a new reasoning mode that thinks before responding — no plugins needed.
What happened
OpenAI released GPT-5, their most capable model to date. It includes native voice input and output (no separate Whisper call), a new 'extended thinking' mode for complex reasoning, and a 200k context window. The API is live today. ChatGPT Plus users get access immediately; API pricing drops ~30% vs GPT-4o.
