When OpenAI launched GPT-5 final week, the corporate mentioned the mannequin would simplify the ChatGPT expertise. OpenAI hoped GPT-5 would act as a type of “one measurement matches all” AI mannequin with a router that may mechanically resolve the way to finest reply person questions. The corporate mentioned this unified method would eradicate the necessity for customers to navigate its mannequin picker — a protracted, sophisticated listing of AI fashions that OpenAI CEO Sam Altman has mentioned he hates — to choose a model of ChatGPT that provides the correct of responses.
Nevertheless it appears to be like like GPT-5 is just not the unified AI mannequin OpenAI hoped it could be.
Altman mentioned in a submit on X Tuesday that the corporate launched new “Auto”, “Quick”, and “Pondering” settings for GPT-5 that each one ChatGPT customers can choose from the mannequin picker. The Auto setting appears to work like GPT-5’s mannequin router that OpenAI initially introduced; nevertheless, the corporate can be giving customers choices to circumnavigate it, permitting them to entry quick and sluggish responding AI fashions straight.
Updates to ChatGPT:Now you can select between “Auto”, “Quick”, and “Pondering” for GPT-5. Most customers will need Auto, however the further management might be helpful for some folks.Charge limits are actually 3,000 messages/week with GPT-5 Pondering, after which additional capability on GPT-5 Pondering…— Sam Altman (@sama) August 13, 2025
Alongside GPT-5’s new modes, Altman mentioned that paid customers can as soon as once more entry a number of legacy AI fashions — together with GPT-4o, GPT-4.1, and o3 — which have been deprecated simply final week.
“We’re engaged on an replace to GPT-5’s character which ought to really feel hotter than the present character however not as annoying (to most customers) as GPT-4o,” Altman wrote within the submit on X. “Nonetheless, one studying for us from the previous few days is we actually simply must get to a world with extra per-user customization of mannequin character.”
ChatGPT’s mannequin picker now appears to be as sophisticated as ever, suggesting that GPT-5’s mannequin router has not universally happy customers as the corporate hoped. The expectations for GPT-5 have been sky excessive, with many hoping that OpenAI would push the boundaries of AI fashions prefer it had with the launch of GPT-4. Nonetheless, GPT-5’s rollout has been rougher than anticipated.
The deprecation of GPT-4o and different AI fashions in ChatGPT sparked a backlash amongst customers who had grown hooked up to the AI fashions’ responses and personalities in ways in which OpenAI had not anticipated. Sooner or later, Altman says the corporate will give customers loads of advance discover if it ever deprecates GPT-4o.

GPT-5’s mannequin router additionally gave the impression to be largely damaged on launch day. That induced some customers to really feel the AI mannequin wasn’t as performant as earlier OpenAI fashions, and compelled Altman to deal with the issue in an AMA session on Reddit. Nonetheless, evidently GPT-5’s router should still not be satisfying for all customers.
“We’re not at all times going to get every part on attempt #1 however I’m very pleased with how shortly the staff can iterate,” wrote OpenAI’s VP of ChatGPT, Nick Turley, in a submit on X Tuesday.
Routing prompts to the correct AI mannequin is a troublesome activity that requires aligning an AI mannequin to a person’s preferences, in addition to the particular query they’re asking. The router then has to decide on which AI mannequin to ship the immediate to in only a cut up second — that manner, if a immediate goes to a quick responding AI mannequin, the response can nonetheless be quick.
Extra broadly, some folks exhibit preferences for AI fashions that transcend quick or sluggish responses. Some customers might just like the verbosity of 1 AI mannequin, whereas others may admire the contrarian solutions of one other.
Human attachment to sure AI fashions is a comparatively new idea that isn’t effectively understood. For instance, tons of of individuals in San Francisco lately held a funeral for Anthropic’s AI mannequin, Claude 3.5 Sonnet, when it was taken offline. In different circumstances, AI chatbots appear to be contributing to mentally unstable folks taking place psychotic rabbit holes.
It appears OpenAI has extra work to do round aligning its AI fashions to particular person person preferences.
