OpenAI Launches GPT-5 for All ChatGPT Users With Native Multimodal Reasoning

GPT-5 lands with OpenAI claiming benchmark leadership across reasoning, coding and instruction-following -- including a meaningful jump on long-context tasks where Claude had historically led. Rolling out to free-tier accounts alongside paid subscribers was the strategic move: it resets the comparison baseline for anyone who had been evaluating cheaper or open alternatives. For affiliate publishers, the free rollout means that comparison search traffic accelerates immediately -- readers want to know whether GPT-5 free is better than Claude Pro, Gemini Advanced or the open-source alternatives. On prose quality, early hands-on reporting suggests GPT-5 closes the gap with Claude on long-form writing, though Claude still has the edge on natural-sounding voice and nuanced instruction-following. The practical advice for power users: run both on your actual workflows for a week before switching subscriptions.
