OpenAI upgrades GPT‑5.5 and retires legacy models
🧭 OpenAI has updated the GPT-5.5 Instant model to improve answer accuracy, pacing, and conversational style while reducing long, bullet-heavy responses to sound more natural. The company will retire legacy models: o3 on August 26 with a 90-day sunset and GPT-4.5 on June 27 with a 30-day sunset. Additionally, OpenAI is integrating a job search tool into ChatGPT to surface live listings and help tailor resumes, and it has enhanced resume editing and export capabilities. These changes are rolling out globally to paid users.
