OpenAI Launches GPT-5, Phasing Out Older Models

OpenAI has officially released GPT-5, its most advanced AI model to date, now accessible via ChatGPT.com. The new iteration surpasses previous versions in writing, coding, and health knowledge, with CEO Sam Altman likening its capabilities to consulting a "legitimate PhD-level expert." GPT-5 also reduces hallucinations compared to earlier releases.

A significant shift is the exclusive availability of GPT-5, displacing GPT-4o and other legacy versions. The model dynamically adjusts response depth based on query complexity, eliminating the need for manual model selection. Plus and Team subscribers can opt for "GPT-5 Thinking" as their base model, while free users face automatic downgrades to lighter versions upon hitting usage limits.

Enhanced literary fluency and translation capabilities headline GPT-5's upgrades. The model's adaptive reasoning and consolidated architecture mark a strategic pivot toward unified, high-performance AI interactions.
