OpenAI has released GPT-5, its latest language model, to all ChatGPT users. CEO Sam Altman described it as a significant step toward artificial general intelligence (AGI), though it doesn't yet reach that level. GPT-5 boasts improved speed, accuracy, and reduced hallucinations. Three versions are available: GPT-5, gpt-5-mini, and gpt-5-nano (API only). Pricing varies across models and user tiers; Pro users get unlimited access and new features like Gmail integration and personality options. GPT-5 features a larger context window for improved understanding of lengthy inputs.
