Last week, OpenAI released the second edition of their fifth GPT model, the GPT-5.2. Within a month since GPT-5.1 made its appearance in the market, many were taken aback by the AI company’s sudden move to launch yet another product before the end of 2025. Many have been deeming this as OpenAI’s approach towards tackling new challenges ever since Google’s latest AI update, Gemini 3, made headlines last month.
When it comes to the differences between the two GPT-5 versions, OpenAI CEO Sam Altman believes the latest model surpassed its predecessor. In his recent X post, Altman showered praise on GPT-5.2. He also presented a tabular analysis of GPT-5.2’s performance when pitted against GPT-5.1 as well as their rival AI models, Gemini and Claude AI.

On December 12, Sam Altman took to his X profile to showcase the progress OpenAI has made so far with the launch of GPT-5.2. Released on the same day, the latest model brings to the forefront new features driven by improvements in its technologies.
As per Microsoft Foundry, “GPT-5.2 series introduces deeper logical chains, richer context handling, and agentic execution that prompts shippable artifacts. For example, design docs, runnable code, unit tests, and deployment scripts can be generated with fewer iterations.“

In his X post, the OpenAI CEO shared a tabular analysis of GPT-5.2 alongside its predecessor, GPT-5.1, Anthropic’s Claude AI, and Google’s Gemini. The post was captioned, “It is a very smart model, and we have come a long way since GPT-5.1.”
The tabular analysis that followed consisted of the percentages that determined how distinctly and efficiently each of the LLMs fared in the parameters of SWE-Bench Pro, GPQA Diamond, CharXiv Reasoning, and FrontierMath.
In all these parameters, GPT-5.2 performed remarkably well in its “Thinking” state when pitted against GPT-5.1 in its respective “Thinking” Mode, along with Claude Opus 4.5, and Gemini 3 Pro. Surprisingly enough, netizens on social media responded differently to the outputs shared by the OpenAI chief.

Social media responds to Sam Altman’s views on GPT-5.2
OpenAI CEO Sam Altman recently hailed the company’s latest LLM version GPT-5.2 as a “very smart model” in comparison with its predecessor GPT-5.1, Claude Opus 4.5, and Gemini 3 Pro. Among users on social media, the results shared by the Chief Executive were received quite warmly. In fact, many users took to the comment section of his X post to appreciate how far ChatGPT has come in terms of efficiency and productivity.
and gpt 5.2 cooked pretty hard as well!

pretty surreal to see the > 300x improvements in cost-perf in a year
2026 is going to be pretty insane!https://t.co/HGGxJShVJw
However, a significant fraction of commenters questioned the necessity of bringing a new version of GPT-5 so soon, especially within a month after the launch of GPT-5.1. At the same time, some users threw light on the need to upgrade 4o instead, since, in their opinion, 4o has greater potential as a productive LLM.
To be honest, 5.1 was a massive step backward from 4o in many ways.

You wouldn't need to 'come a long way' if you simply didn't break what was already working perfectly. You could achieve instant success with much less effort: Just turn off the Safety Router and let us use the…
What remains now is to see how rival AI companies would take this new update. Given the fact that OpenAI has to declare “Code Red” immediately after Google’s Gemini 3 Pro broke the internet, it will be interesting to look at how GTP-5.2 will fare in the days to come.
