OpenAI ChatGPT GPT-5.5 model deprecation job search

GPT-5.5 Gets Smarter, o3 Gets the Axe

4 June 2026

OpenAI has released an update to its GPT-5.5 Instant model, improving response accuracy, style, and readability by reducing overly long or bullet-heavy answers to sound more natural. At the same time, the company is retiring legacy models, with GPT-4.5 set to be removed from ChatGPT on June 27 and o3 on August 26. OpenAI is also adding a job search feature to ChatGPT, enabling users to find live job listings from sources like Indeed and Upwork, with personalised recommendations and improved resume-building tools.

OpenAI has quietly pushed out an update to GPT-5.5 Instant, the model it launched back in April, while simultaneously putting several older models on notice.

The changes to GPT-5.5 Instant are mostly about quality and tone rather than raw capability. Responses should now be more accurate, better phrased, and crucially, less addicted to bullet points. If you've ever received a ChatGPT answer that looked like someone exploded a PowerPoint deck, this is OpenAI trying to fix that. The goal is something closer to natural conversation rather than a corporate memo with seventeen sub-headings.

OpenAI also says the model will be better paced for practical tasks. Vague, but encouraging.

The retirement queue is filling up

Alongside the upgrades, OpenAI is clearing house. GPT-4.5 gets pulled from ChatGPT on June 27, giving users a 30-day window to make their peace with it. o3 survives a little longer, with a retirement date of August 26 and a 90-day sunset period.

The o3 departure probably won't generate many complaints. GPT-4.5 is a different story. It sat closer to GPT-4o in character and picked up a following partly because of how it felt to talk to. More personal, more textured. That quality was apparently also what made it controversial. Either way, it's going.

Both models are currently accessible to paid subscribers only, which limits the blast radius somewhat.

ChatGPT now does job hunting

Separately, OpenAI is rolling out job search functionality directly inside ChatGPT. The feature pulls live listings from Indeed, Upwork, Appcast, and general web sources, and supposedly tailors results based on your experience, skills, and stated goals. You can follow links through to the original listings to apply.

ChatGPT has always been reasonably useful for polishing a CV. Finding the jobs in the first place was always someone else's problem. Now OpenAI is having a go at that too, and has apparently also improved the resume creation and editing tools while it was at it, including proper export formatting.

Whether the job matching is actually good remains to be seen. "Personalised recommendations" is a phrase that has covered a multitude of sins across many platforms over the years. Still, if it surfaces genuinely relevant roles rather than spray-and-pray listings, it could be legitimately useful.

All of this is rolling out gradually across regions.
