Wow, there's a lot going on with this pelican riding a bicycle: https://gist.github.com/simonw/c31d7afc95fe6b40506a9562b5e83...

Is that the first SVG pelican with drop shadows?

No, I got drop shadows from DeepSeek 3.2 recently https://simonwillison.net/2025/Dec/1/deepseek-v32/ (probably others as well.)

Is it me, or did it still get at least three placements of components (RAM and PCIe slots, plus it's DisplayPort and not HDMI) in the motherboard image[0] completely wrong? Why would they use that as a promotional image? 0: https://images.ctfassets.net/kftzwdyauwt9/6lyujQxhZDnOMruN3f...

Yep, the point we wanted to make here is that GPT-5.2's vision is better, not perfect. Cherrypicking a perfect output would actually mislead readers, and that wasn't our intent.

Is Adaptive Reasoning gone from GPT-5.2? It was a big part of the release of 5.1 and Codex-Max. Really felt like the future.

Great! It'll be SOTA for a couple of weeks until the quality degrades due to throttling. I'll stick with plug and play API instead.

Due to the "Code Red" threat from Gemini 3, I suspect they'll hold off throttling for longer than usual (by incinerating even more investor capital than usual).

Jump in and soak up that extra-discounted compute while the getting is good, kids! Personally, I recently retired so I just occasionally mess around with LLMs for casual hobby projects, so I've only ever used the free tier of all the providers. Having lived through the dot com bubble, I regret not soaking up more of the free and heavily subsidized stuff back then. Trying not to miss out this time. All this compute available for free or below cost won't last too much longer...

The only table where they showed comparisons against Opus 4.5 and Gemini 3: https://x.com/OpenAI/status/1999182104362668275 https://i.imgur.com/e0iB8KC.png

100% on the AIME (assuming its not in the training data) is pretty impressive. I got like 4/15 when I was in HS...

The no tools part is impressive, with tools every model gets 100%

From GPT 5.1 Thinking: ARC AGI v2: 17.6% -> 52.9% SWE Verified: 76.3% -> 80% That's pretty good!

Note that GPT 5.2 newly supports a "xhigh" reasoning level, which could explain the better benchmarks. It'll be noteworthy to see the cost-per-task on ARC AGI v2.

5.1-codex supports that too, no? Pretty sure I’ve been using xhigh for at least a week now

> 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? Reminds me of that time an OAI released wildly inaccurate copy/pasted bar charts.

It does seem to raise fair questions about either the utility of these tools, or adoption inertia. If not even OpenAI feels compelled to integrate this kind of model-check into their pipeline, what's that say about the business world at-large? Is it that it's too onerous to set up, is it that it's too hard to get only true-positive corrections, is it that it's too low value for the effort?

> what's that say about the business world at-large?

Nothing. OpenAI is a terrible baseline to extrapolate anything from.

That would be a laudable goal, but I feel like it's contradicted by the text: > Even on a low-quality image, GPT‑5.2 identifies the main regions and places boxes that roughly match the true locations of each component I would not consider it to have "identified the main regions" or to have "roughly matched the true locations" when ~1/3 of the boxes have incorrect labels . The remark "even on a low-quality image" is n…

Yeah, what it's calling RAM slots is the CMOS battery. What it's calling the PCIE slot is the interior side of the DB-9 connector. RAM slots and PCIE slots are not even visible in the image.

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.

I thought whenever the knowledge cutoff increased that meant they’d trained a new model, I guess that’s completely wrong?

They add new data to the existing base model via continuous pre-training. You save on pre-training, the next token prediction task, but still have to re-run mid and post training stages like context length extension, supervised fine tuning, reinforcement learning, safety alignment ...

Claude’s voice chat isn’t “native” though, is it? It feels like it’s speech-to-text-to-LLM and back.

You can test it by asking it to: change the pitch of its voice, make specific sounds (like laughter), differentiate between words that are spelled the same but pronounced differently (record and record), etc.
