GPT-5.6, Grok 4.5, Claude, and Muse Spark build the same 4 apps

Interesting tests being done but I can't help but think it limits testing innovation in some way given that the requested apps are essentially all clones of others

Similarly, we updated our model arena (52 apps each built by 26 models) to have GPT 5.6 Sol, Terra, and Luna today: https://arena.logic.inc/ It's really interesting to see the Sol/Terra/Luna apps side-by-side. I need to add these stats somewhere in the UI, but one interesting take away: Terra took 1/2 as much wall-clock time as Sol, but Luna took more wall-clock time than Sol (by about 23%). It's still much much cheaper, but it seems like Terra is likely a more optimal time/cost balance for most use cases. The Terra quality is usually nearly as good as Sol, but much faster and cheaper. I do appreciate Sol's design sensibilities (see, for example, the audio sequencer). It's the first model in a while that is clearly distinct on that front. They'd all converged to very similar visuals for a while.

This does seem to validate the critique that models like GLM are benchmaxxed and not as close to the frontier as you’d think based on their numbers.

"This isn't objective." Correct, and we are not pretending it is. We are not handing down a scientific verdict. Actually, you are doing rational investigation in a fuzzy probabilistic new/emergent space, with open sharing to the world. I don’t understand why people downplay themselves and put on a pedestal others supposedly serious sciences.

The cost seems to be using the wrong symbol: ¢ vs $

"One honest caveat", "no glitches, no color changes" good tests and I read it to the end but I wish it was written by a human.

> We generated a big pile of artifacts, we are publishing all of them, and you can form your own opinion. My opinion is that spamming HN with two gimmicky "one-shot prompting shootout" marketing pieces in two days does not build confidence about either your technical or marketing expertise.

(LM)Arena is basically this. IMO it’s the best benchmark that avoids benchmaxxing Agent: https://arena.ai/leaderboard/agent Web dev: https://arena.ai/leaderboard/code/webdev Currently Fable and 5.6 are neck and neck on web dev which is basically the same finding as this.

My concern with most of these visual benchmarks, popular as they are, is that they are likely more indicative of knowledge (i.e. how comprehensive the training data is and how well it can be retrieved from the model) than of reasoning ability. I don't see in particular how a model would construct a CoT that mapped somehow to a representation of the cube geometry and its animations in latent space without a large chunk of that being pre-existing information.

"Elon and Bezos watch a Blue Origin landing" svgs are super cute, and incredibly like children's drawings. They also nail Bezos' features pretty well.

It’s interesting how all the model names and versions are like SKUS taking up space on a display shelf. I look forward to whatever Sagittarius A* does!

> Separate question, separate table. This is our standard latency harness (three short prompts, five reps, 400-token cap), not the build tasks. tok/s is output tokens over wall-clock, uniform for all. > so their tok/s is a ceiling, not a true decode rate. The clear read: the GPT-5.6 tiers are the snappiest models here on short prompts (Luna answers in about a second), Qwen is absurdly cheap and fast, and DeepSeek and GLM are the slowpokes You put in a lot of good work, and kudos for that, but man, reading paragraphs like these just puts me off of the entire piece. Like…how hard would it have been really to type these two sentences by hand, in your own natural voice?

Is this how I learn that Bezos now has a beard? Interesting that it is a detail that all of the models chose to include (unless that was in the prompt and just not put in the post).

Obviously AI-written, but I'm confused with the results: Muse Spark has the best Rubik's cube by far, the only one properly animating, yet it gets a 2/5 (edit: seems to be an issue with inline videos)

orliesaurus

Really nice breakdown, surprised by the results - especially the fact that OSS models were so behind on most task... (lol at the SVG of the moon without any sign of life by GLM-5.2)

orliesaurus

Missing the exact prompts - would love to replicate...but also curious how you prompted these: they could be a big reason why some models failed completely at rendering SVGs (ie. GLM 5.2)

platinumrad

Maybe I'm a control freak, but asking agents to one-shot random apps is nothing like how I actually use AI in software engineering.

master_crab

A lot of these are visual-heavy tests that often require first person sight to confirm results. Considering GLM isn’t multimodal, that might explain why it did better on the calculator question and not much else.

Could you make the tables sortable?
