GPT-4.5 emphasized broad pretraining, conversational nuance, and general-purpose knowledge; GPT-5 launched as a ChatGPT system with fast and reasoning models plus a router. These are historical launch descriptions, and model access changes over time.
Jin Dive
OpenAI introduced GPT-4.5 as a research preview in February 2025, describing it as a large general-purpose model that focused on broader world knowledge, nuanced intent, and warm conversation rather than explicit reasoning before answering. GPT-5 launched in August 2025 as a unified ChatGPT system with a fast model, a deeper reasoning model, and a real-time router. In the API, OpenAI described direct access to the reasoning model and released GPT-5, GPT-5 mini, and GPT-5 nano. OpenAI’s release notes state that GPT-4.5 was retired from ChatGPT on June 27, 2026; the notice said the change applied to ChatGPT only, with no API change at that time.

Ojo iwaju ti OpenAI GPT-4.5 ati GPT-5
OpenAI’s model families and access channels continue to change. Historical comparisons should name the release date and distinguish ChatGPT availability from API access. Use current model docs and release notes for present-day availability.
