> Developments to the model architecture contribute to the significantly improved performance from previous model families.

I wonder how significant this is. DeepMind was always more research-oriented that OpenAI, which mostly scaled things up. They may have come up with a significantly better architecture (Transformer MoE still leaves a lot of room).

The reported results where GPT 5.1 beats Gemini 3 are on SWE Bench Verified, and GPT 5.1 Codex also beats Gemini 3 on Terminal Bench.

You're right on SWE Bench Verified, I missed that and I'll delete my comment.

GPT 5.1 Codex beats Gemini 3 on Terminal Bench specifically on Codex CLI, but that's apples-to-oranges (hard to tell how much of that is a Codex-specific harness vs model). Look forward to seeing the apples-to-apples numbers soon, but I wouldn't be surprised if Gemini 3 wins given how close it comes in these benchmarks.

Also does not beat GPT-5.1 Codex on terminal bench (57.8% vs 54.2%): https://www.tbench.ai/ I did not bother verifying the other claims.

Not apples-to-apples. "Codex CLI (GPT-5.1-Codex)", which the site refers to, adds a specific agentic harness, whereas the Gemini 3 Pro seems to be on a standard eval harness. It would be interesting to see the apples-to-apples figure, i.e. with Google's best harness alongside Codex CLI.

Do you mean that Gemini 3 Pro is "vanilla" like GPT 5.1 (non-Codex)?

At least at the moment, coming in late seems to matter little. Anyone with money can trivially catch up to a state of the art model from six months ago. And as others have said, late is really a function of spigot, guardrails, branding, and ux, as much as it is being a laggard under the hood.

> Anyone with money can trivially catch up to a state of the art model from six months ago. How come apple is struggling then?

It looks more like a strategic decision tbh.

The may want to use 3rd party or just wait for AI to be more stable to see how people actually use it instead of adding slop in the core of their product.

This is a big jump in most benchmarks.And if it can match other models in coding while having that Google TPM inference speed and the actually native 1m context window, it's going to be a big hit. I hope it's isn't such a sycophant like the current gemini 2.5 models, it makes me doubt its output, which is maybe a good thing now that I think about it.

> it's over for the other labs.

Its not over and never will be for 2 decade old accounting software, it is definitely will not be over for other AI labs.

> it's over for the other labs. What's with the hyperbole? It'll tighten the screws, but saying that it's "over for the other labs' might be a tad premature.

I mean over in that I don't see a need to use the other models. Codex models are the best but incredibly slow. Claude models are not as good(IMO) but much faster. If gemini can beat them while having being faster and having better apps with better integrations, i don't see a reason why I would use another provider.

It is interesting that the Gemini 3 beats every other model on these benchmarks, mostly by a wide margin, but not on SWE Bench. Sonnet is still king here and all three look to be basically on the same level. Kind of wild to see them hit such a wall when it comes to agentic coding

From my personal experience using the CLI agentic coding tools, I think gemini-cli is fairly on par with the rest in terms of the planning/code that is generated. However, when I recently tried qwen-code, it gave me a better sense of reasoning and structure that geimini. Claude definitely has it's own advantages but is expensive(at least for some if not for all).

My point is, although the model itself may have performed in benchmarks, I feel like there are other tools that are doing better just by adapting better training/tooling. Gemini cli, in particular, is not so great looking up for latest info on web. Qwen seemed to be trained better around looking up for information (or to reason when/how to), in comparision. Even the step-wise break down of work felt different and a bit smoother.

I do, however, use gemini cli for the most part just because it has a generous free quota with very few downsides comparted to others. They must be getting loads of training data :D.

I know this is a little controversial but the lack of performance on SWE-bench is hugely disappointing I think economically. These models don’t have any viable path to profitability if they can’t take engineering jobs.

Really? If they can make an engineer more productive, that's worth a lot. Naive napkin math: 1.5X productivity on one $200k/year engineer is worth $100k/year.

I saw this on Reddit earlier today. Over there the source of this file was given as: https://web.archive.org/web/20251118111103/https://storage.g... The bucket name "deepmind-media" has been used in the past on the deepmind official site, so it seems legit.

Prediction markets were expecting today to be the release. So I wouldn't be surprised if they do a release today, tomorrow, or Thursday (around Nvidia earnings).
