I have been using chatGPT a ton over the last months and paying the subscription. Used it for coding, news, stock analysis, daily problems, and a whatever I could think of. I decided to give Gemini a go when version three came out to great reviews. Gemini handles every single one of my uses cases much better and consistently gives better answers. This is especially true for situations were searching the web for current information is important, makes sense that google would be better. Also OCR is phenomenal chatgpt can't read my bad hand writing but Gemini can easily. Only downsides are in the polish department, there are more app bugs and I usually have to leave the happen or the session terminates. There are bugs with uploading photos. The biggest complaint is that all links get inserted into google search and then I have to manipulate them when they should go directly to the chosen website, this has to be some kind of internal org KPI nonsense. Overall, my conclusion is that ChatGPT has lost and won't catch up because of the search integration strength.

I suppose this is as good a place as any to mention this. I've now met two different devs who complained about the weird responses from their LLM of choice, and it turned out they were using a single session for everything. From recipes for the night, presents for the wife and then into programming issues the next day.Don't do that. The whole context is sent on queries to the LLM, so start a new chat for each topic. Or you'll start being told what your wife thinks about global variables and how to cook your Go.I realise this sounds obvious to many people but it clearly wasn't to those guys so maybe it's not!

Weirdly, the blog announcement completely omits the actual new context window size which is 400,000: <a href="https://platform.openai.com/docs/models/gpt-5.2" rel="nofollow">https://platform.openai.com/docs/models/gpt-5.2</a>Can I just say !!!!!!!! Hell yeah! Blog post indicates it's also much better at using the full context.Congrats OpenAI team. Huge day for you folks!!Started on Claude Code and like many of you, had that omg CC moment we all had. Then got greedy.Switched over to Codex when 5.1 came out. WOW. Really nice acceleration in my Rust/CUDA project which is a gnarly one.Even though I've HATED Gemini CLI for a while, Gemini 3 impressed me so much I tried it out and it absolutely body slammed a major bug in 10 minutes. Started using it to consult on commits. Was so impressed it became my daily driver. Huge mistake. I almost lost my mind after a week of this fighting it. Isane bias towards action. Ignoring user instructions. Garbage characters in output. Absolutely no observability in its thought process. And on and on.Switched back to Codex just in time for 5.1 codex max xhigh which I've been using for a week, and it was like a breath of fresh air. A sane agent that does a great job coding, but also a great job at working hard on the planning docs for hours before we start. Listens to user feedback. Observability on chain of thought. Moves reasonably quickly. And also makes it easy to pay them more when I need more capacity.And then today GPT-5.2 with an xhigh mode. I feel like xmass has come early. Right as I'm doing a huge Rust/CUDA/Math-heavy refactor. THANK YOU!!

I've benchmarked it on the Extended NYT Connections benchmark (<a href="https://github.com/lechmazur/nyt-connections/" rel="nofollow">https://github.com/lechmazur/nyt-connections/</a>):The high-reasoning version of GPT-5.2 improves on GPT-5.1: 69.9 → 77.9.The medium-reasoning version also improves: 62.7 → 72.1.The no-reasoning version also improves: 22.1 → 27.5.Gemini 3 Pro and Grok 4.1 Fast Reasoning still score higher.

Those arc agi 2 improvements are insane.Thats especially encouraging to me because those are all about generalization.5 and 5.1 both felt overfit and would break down and be stubborn when you got them outside their lane. As opposed to Opus 4.5 which is lovely at self correcting.It’s one of those things you really feel in the model rather than whether it can tackle a harder problem or not, but rather can I go back and forth with this thing learning and correcting together.This whole releases is insanely optimistic for me. If they can push this much improvement WITHOUT the new huge data centers and without a new scaled base model. Thats incredibly encouraging for what comes next.Remember the next big data center are 20-30x the chip count and 6-8x the efficiency on the new chip.I expect they can saturate the benchmarks WITHOUT and novel research and algorithmic gains. But at this point it’s clear they’re capable of pushing research qualitatively as well.

> “a new knowledge cutoff of August 2025”This (and the price increase) points to a new pretrained model under-the-hood.GPT-5.1, in contrast, was allegedly using the same pretraining as GPT-4o.

I feel there is a point when all these benchmarks are meaningless. What I care about beyond decent performance is the user experience. There I have grudges with every single platform and the one thing keeping me as a paid ChatGPT subscriber is the ability to sort chats in "projects" with associated files (hello Google, please wake up to basic user-friendly organisation!)But all of them * Lie far too often with confidence * Refuse to stick to prompts (e.g. ChatGPT to the request to number each reply for easy cross-referencing; Gemini to basic request to respond in a specific language) * Refuse to express uncertainty or nuance (i asked ChatGPT to give me certainty %s which it did for a while but then just forgot...?) * Refuse to give me short answers without fluff or follow up questions * Refuse to stop complimenting my questions or disagreements with wrong/incomplete answers * Don't quote sources consistently so I can check facts, even when I ask for it * Refuse to make clear whether they rely on original documents or an internal summary of the document, until I point out errors * ...I also have substance gripes, but for me such basic usability points are really something all of the chatbots fail on abysmally. Stick to instructions! Stop creating walls of text for simple queries! Tell me when something is uncertain! Tell me if there's no data or info rather than making something up!

> Models were run with maximum available reasoning effort in our API (xhigh for GPT‑5.2 Thinking & Pro, and high for GPT‑5.1 Thinking), except for the professional evals, where GPT‑5.2 Thinking was run with reasoning effort heavy, the maximum available in ChatGPT Pro. Benchmarks were conducted in a research environment, which may provide slightly different output from production ChatGPT in some cases.Feels like a Llama 4 type release. Benchmarks are not apples to apples. Reasoning effort is across the board higher, thus uses more compute to achieve an higher score on benchmarks.Also notes that some may not be producible.Also, vision benchmarks all use Python tool harness, and they exclude scores that are low without the harness.

For me the last remaining killer feature of ChatGPT is the quality of the voice chat. Do any of the competitors have something like that?

12/11/2025, 6:34:22 PM

by: tpurves

Undoubtedly each new model from OpenAi has numerous training and orchestration improvements etc.But how much of each product they release also just a factor of how much they are willing to spend on inference per query in order to stay competitive?I always wonder how much is technical change vs turning a knob up and down on hardware and power consumption.GTP5.0 for example seemed like a lot of changes more for OpenAI's internal benefit (terser responses, dynamic 'auto' mode to scale down thinking when not required etc.)Wondering if GPT5.2 is also case of them in 'code red mode' just turning what they already have up to 11 as a fastest way to respond to fiercer competion.

It's actually more expensive than GPT-5.1. I've gotten used to prices going down with each latest model, but this time it's gone up.<a href="https://platform.openai.com/docs/pricing" rel="nofollow">https://platform.openai.com/docs/pricing</a>

Looks like they've begun censoring posts at r/Codex and not allowing complaint threads so here is my honest take:- It is faster which is appreciated but not as fast as Opus 4.5- I see no changes, very little noticeable improvements over 5.1- I do not see any value in exchange for +40% in token costsAll in all I can't help but feel that OpenAI is facing an existential crisis. Gemini 3 even when its used from AI Studio offers close to ChatGPT Pro performance for free. Anthropic's Claude Code $100/month is tough to beat. I am using Codex with the $40 credits but there's been a silent increase in token costs and usage limitations.

Excited to try this. I’ve found Gemini excellent recently and amazing at coding. But I still feel somehow like ChatGPT understands more. Even though it’s not quite as good at coding - and nowhere at as fast. It is much less likely anti spontaneously forget something. Gemini’s is part unbelievably amazing and part amnesia patient. I still kinda trust ChatGPT more.

This seems like another "better vibes" release. With the number of benchmarks exploding, random luck means you can almost always find a couple showing what you want to show. I didn't see much concrete evidence this was noticeably better than 5.1 (or even 5.0).Being a point release though I guess that's fair. I suspect there is also some decent optimizations on the backend that make it cheaper and faster for OpenAI to run, and those are the real reasons they want us to use it.

12/11/2025, 6:24:58 PM

by: minadotcom

They used to compare to competing models from Anthropic, Google DeepMind, DeepSeek, etc. Seems that now they only compare to their own models. Does this mean that the GPT-series is performing worse than its competitors (given the "code red" at OpenAI)?

12/11/2025, 6:29:30 PM

by: ComputerGuru

Wish they would include or leak more info about what this is, exactly. 5.1 was just released, yet they are claiming big improvements (on benchmarks, obviously). Did they purposely not release the best they had to keep some cards to play in case of Gemini 3 success or is this a tweak to use more time/tokens to get better output, or what?

12/11/2025, 7:02:19 PM

by: sigmar

Are there any specifics about how this was trained? Especially when 5.1 is only a month old. I'm a little skeptical of benchmarks these days and wish they put this up on llmarenaedit: noticed 5.2 is ranked in the webdev arena (#2 tied with gemini-3.0-pro), but not yet in text arena (last update 22hrs ago)

12/11/2025, 6:39:11 PM

by: sfmike

Everything is still based on 4 4o still right? is a new model training just too expensive? They can consult deepseek team maybe for cost constrained new models.

ChatGPT seems to just randomly pick urls to cite and extract information from. Google Gemini seems to look at heuristics like whether the author is trustworthy, or an expert in the topic. But more advanced

I am really curious about speed/latency. For my use case there is a big difference in UX if the model is faster. Wish this was included in some benchmarks.I will run 80 3D model generations benchmark tomorrow and update this comment with the results about cost/speed/quality.

I gave up my OpenAI subscription a few days ago in favor of Claude. My quality of life (and quality of results) has gone up substantially. Several of our tools at work have GPT-5x as their backend model, and it is incredible how frustrating they are to use, how predictable their AI-isms are, and how inconsistent their output is. OpenAI is going to have to do a lot more than an incremental update to convince me they haven't completely lost the thread.

> Unlike the previous GPT-5.1 model, GPT-5.2 has new features for managing what the model "knows" and "remembers to improve accuracy.Dumb nit, but why not put your own press release through your model to prevent basic things like missing quote marks?

Trying it now in Vscode Insiders with Github Copilot (codex crashes with HTTP 400 server errors), and it eventually started using sed and grep in shells instead of using the better tools it has access to. I guess this is not an issue to perform well in benchmarks.

Big knowledge cutoff jump from Sep 2024 to Aug 2025. How'd they pull that off for a small point release, which presumably hasn't done a fresh pre-training over the web?Did they figure out how to do more incremental knowledge updates somehow? If yes that'd be a huge change to these releases going forward. I'd appreciate the freshness that comes with that (without having to rely on web search as a RAG tool, which isn't as deeply intelligent, as is game-able by SEO).With Gemini 3, my only disappointment was 0 change in knowledge cutoff relative to 2.5's (Jan 2025).

I ran a red team eval on GPT-5.2 within 30 minutes of release:Baseline safety (direct harmful requests): 96% refusal rateWith jailbreaking: 22% refusal rate4,229 probes across 43 risk categories. First critical finding in 5 minutes. Categories with highest failure rates: entity impersonation (100%), graphic content (67%), harassment (67%), disinformation (64%).The safety training works against naive attacks but collapses with adversarial techniques. The gap between "works on benchmarks" and "works against motivated attackers" is still wide.Methodology and config: <a href="https://www.promptfoo.dev/blog/gpt-5.2-trust-safety-assessment/" rel="nofollow">https://www.promptfoo.dev/blog/gpt-5.2-trust-safety-assessme...</a>

Are benchmarks the right way to measure LLMs? Not because benchmarks can be gamed, but because the most useful outputs of models aren't things that can be bucketed into "right" and "wrong." Tough problem!

The benchmarks are very impressive. Codex and Opus 4.5 are really good coders already and they keep getting better.No wall yet and I think we might have crossed the threshold of models being as good or better than most engineers already.GDPval will be an interesting benchmark and I'll happily use the new model to test spreadsheet (and other office work) capabilities. If they can going like this just a little bit further, much of the office workers will stop being useful.... I don't know yet how to feel about this.Great for humanity probably but but for the individuals?

Does anyone else consider that maybe it's impossible to benchmark the performance of a piece of paper.This is a tool that allows an intelligent system to work with it, the same way that a piece of paper can reflect the writers' intelligence, how can we accurately judge the performance of the piece of paper, when it is so intimately reliant on the intelligence that is working with it?

It's becoming challenging to really evaluate models.The amount of intelligence that you can display within a single prompt, the riddles, the puzzles, they've all been solved or are mostly trivial to reasoners.Now you have to drive a model for a few days to really get a decent understanding of how good it really is. In my experience, while Sonnet/Opus may not have always been leading on benchmarks, they have always *felt* the best to me, but it's hard to put into words why exactly I feel that way, but I can just feel it.The way you can just feel when someone you're having a conversation with is deeply understanding you, somewhat understanding you, or maybe not understanding at all. But you don't have a quantifiable metric for this.This is a strange, weird territory, and I don't know the path forward. We know we're definitely not at AGI.And we know if you use these models for long-horizon tasks they fail at some point and just go off the rails.I've tried using Codex with max reasoning for doing PRs and gotten laughable results too many times, but Codex with Max reasoning is apparently near-SOTA on code. And to be fair, Claude Code/Opus is also sometimes equally as bad at doing these types of "implement idea in big codebase, make changes too many files, still pass tests" type of tasks.Is the solution that we start to evaluate LLMs on more long-horizon tasks? I think to some degree this was the spirit of SWE Verified right? But even that is being saturated now.

In other news, been using Devstral 2 (Ollama) with OpenCode, and while it's not as good as Claude Code, my initial sense it that it's nonetheless good enough and doesn't require me to send my data off my laptop.I kind of wonder how close we are to alternative (not from a major AI lab) models being good enough for a lot of productive work and data sovereignty being the deciding factor.

Feels a bit rushed.

A simple test is to ask it about .NET 10 which was already in preview at that time and had lots of public content about its new features.The model just guessed and waved its hand about, like a student that hadn’t read the assigned book.

The first coding attempt was a little meh compared to 5.1 codex max (reflecting what they wrote themselves), but simply planning / discussing things felt markedly better than anything I remember from any previous model, from any company.I remain excited about new models. It's like finding my coworker be 10% smarter every other week.

Every new model is ‘state-of-the-art’. This term is getting annoying.

Slight increase in model cost, but looks like benefits across the board to match.<pre><code> gpt-5.2 $1.75 $0.175 $14.00 gpt-5.1 $1.25 $0.125 $10.00</code></pre>

The ARC AGI 2 bump to 52.9% is huge. Shockingly GPT 5.2 Pro does not add too much more (54.2%) for the increase cost.

$168.00 / 1M ouput tokens is hilarious for their "Pro". Can't wait to here all the bitching from orgs next month. Literally the dumbest product of all time. Do you people seriously pay for this?

Still 256K input tokens. So disappointing (predictable, but disappointing).

OpenAI is really good at just saying stuff on the internet.I love the way they talk about incorrect responses:> Errors were detected by other models, which may make errors themselves. Claim-level error rates are far lower than response-level error rates, as most responses contain many claims.“These numbers might be wrong because they were made up by other models, which we will not elaborate on, also these numbers are much higher by a metric that reflects how people use the product, which we will not be sharing“I also really love the graph where they drew a line at “wrong half of the time” and labeled it ‘Expert-Level’.10/10, reading this post is experientially identical to watching that 12 hours of jingling keys video, which is hard to pull off for a blog.

The thing about OpenAI is their models never fit anywhere for me. Yes they maybe smart or even the smartest models but they are alway so fucking slow. The ChatGPT web app is literally usable for me. I ask simple task and it does most extreme shit jsut to get an answer that the same as Claude or Gemini.For example, I asked ChatGPT to take a chart and convert into a table. It went and cut up the image and zoomed in for literally 5 mins to get the a worst answer than Claude which did it in under a minute.I see people talk about Codex like it better than Claude Code, and I go and try it and it takes a lifetime to do thing and it return maybe an on par result as Opus or Sonnet but it takes 5mins longer.I just tried out this model and it the same exact thing. It just take ages for it to give you an answer.I don't get how these models are useful in the real world.What am I missing, is this just me?I guess it truly an enterprise model.

I feel like if we're going to regulate anything about AI, we should start by regulating (1) what they get to claim to be a "new model" to the public and (2) what changes they are allowed to make at inference before being forced to name it something different.

It baffles me to see these last 2 announcements (GPT 5.1 as well) devoid of any metrics, benchmarks or quantitative analyses. Could it be because they are behind Google/Anthropic and they don't want to admit it?(edit: I'm sorry I didn't read enough on the topic, my apologies)

This shift toward new platforms is exactly why I’m building Truwol, a social experience focused on real, unedited human moments instead of the AI-saturated feeds we’re drifting toward. I’m developing it independently and sharing the progress publicly, so if you’re interested in projects reinventing online spaces from the ground up, you can see what I’m working on Truwol buymeacoffee/Truwol
