OpenAI Rolls Out GPT-5.3 Instant in ChatGPT

OpenAI on Tuesday announced the rollout of GPT-5.3 Instant, an update to ChatGPT’s default model aimed at making conversations feel less awkward and preachy, and “more directly” helpful.

In a product post, OpenAI said the new version reduces overly cautious refusals, trims unnecessary disclaimers, and delivers more accurate answers. The changes reflect user complaints that earlier versions could sound stiff or overbearing in everyday interactions.

“More accurate, less cringe,” OpenAI wrote on X. “We heard your feedback loud and clear.”

Rather than introducing new capabilities, the update targets routine interactions. OpenAI said earlier versions sometimes declined questions they could safely answer, or interrupted responses with lengthy explanations about safety limits.

“GPT‑5.2 Instant eventually answers the question, but in an attempt to explain its safety boundaries, leads with a lengthy preamble about what it cannot help with,” OpenAI wrote. “GPT‑5.3 Instant, on the other hand, gets right into the response.”

OpenAI reported improvements in factual reliability alongside the tone changes, claiming that internal evaluations showed hallucination rates dropped by nearly 30%.

“On the higher-stakes evaluation, GPT‑5.3 Instant reduces hallucination rates by 26.8% when using the web and 19.7% when relying only on its internal knowledge, compared to prior models,” OpenAI said. “On the user-feedback evaluation, hallucinations decrease by 22.5% with web use and 9.6% without web access.”

OpenAI did not explain what it defines as “cringe,” but noted that the new model includes stronger writing abilities, comparing GPT-5.2 and 5.3’s ability to write poetry.

“5.4 sooner than you think,” the company said in a separate post, which drew swift mockery from users on X, suggesting that the tease was due to recent backlash against the firm for its deal with the Pentagon.

GPT-5.3 Instant replaces the default ChatGPT model starting today, the company said, while GPT-5.2 Instant remains accessible under legacy options for paid subscribers during a transition period ending in early June.

The update drew mixed reactions on social media. Some users praised the focus on more direct responses without unnecessary disclaimers, while others argued the real “cringe” at play was agreeing to a contract with the U.S. Department of Defense when rival Anthropic declined due to safety concerns.

Others complained that GPT-5.3 would never match the sense of intimacy many associated with the now-depreciated GPT-4o, and called for the popular model’s return.

Last summer, OpenAI faced a surge in backlash after the company abruptly replaced the popular GPT-4o with GPT-5, prompting complaints that the new model felt colder and less supportive. Users flooded forums with criticism, and some threatened to cancel subscriptions, leading OpenAI to restore GPT-4o for paid users.

In January, OpenAI announced that GPT-4o and its variants would be officially retired as of February 13.

“I think we’ve learned a lesson about what it means to upgrade a product for hundreds of millions of people in one day,” OpenAI CEO Sam Altman said at the time, calling the reversal a wake-up call and “a lesson in upgrading a product used by hundreds of millions of people” at once.

OpenAI did not immediately respond to a request for comment by Decrypt.
