Gotta love how Claude is always conventiently left out of all of these benchmark lists. Anthropic really is in a league of their own right now.

Gemini Pro 2.5 usually beats Sonnet 3.7 at coding.

Agreed, the pricing is just outrageous at the moment. Really hoping Claude 3.8 is on the horizon soon; they just need to match the 1M context size to keep up. Actual code quality seems to be equal between them.

I similarly have a small, simple spatial reasoning problem that only reasoning models get right, and not all of them, and which Qwen3 on max reasoning still gets wrong. > I put a coin in a cup and slam it upside-down on a glass table.

Yup, it flunked that one. I also have a question that LLMs always got wrong until ChatGPT o3, and even then it has a hard time (I just tried it again and it needed to run code to work it out). Qwen3 failed, and every time I asked it to look again at its solution it would notice the error and try to solve it again, failing again: > A man wants to cross a river, and he has a cabbage, a goat, a wolf and a lion.

i tried grok 3 with Think and it was right also with pretty good thinking

I have a small physics-based problem I pose to LLMs. It's tricky for humans as well, and all LLMs I've tried (GPT o3, Claude 3.7, Gemini 2.5 Pro) fail to answer correctly. If I ask them to explain their answer, they do get it eventually, but none get it right the first time. Qwen3 with max thinking got it even more wrong than the rest, for what it's worth.

This 61GB one: https://ollama.com/library/qwen3:30b-a3b-fp16 You can see it's roughly the same size as the one in the official repo (16 files of 4GB each): https://huggingface.co/Qwen/Qwen3-30B-A3B/tree/main

fp16 is overkill though. 8-bit is the sweet spot before perf degradation starts getting noticeable.

I haven't yet seen any evals comparing the original Qwen3-30B-A22B with https://ollama.com/library/qwen3:30b-a3b-q8_0

The large MoE could be the DeepSeek V3 for people with just 128gb of (V)RAM.

The smallest quantized version of the large MoE model on ollama is 143GB: https://ollama.com/library/qwen3:235b-a22b-q4_K_M Is there a smaller one?

Running the 3 bit quant of https://huggingface.co/unsloth/Qwen3-235B-A22B-GGUF now on a 128GB macbook.

Smaller quantizations are possible [1], but I think you're right in that you wouldn't want to run anything substantially smaller than 128 GB. Single-GPU on 1x H200 (141 GB) might be feasible though (if you have some of those lying around...)

With all the different open-weight models appearing, is there some way of figuring out what model would work with sensible speed (> X tok/s) on a standard desktop GPU ? I.e. I have Quadro RTX 4000 with 8G vram and seeing all the models https://ollama.com/search here with all the different sizes, I am absolutely at loss which models with which sizes would be fast enough. I.e. there is no point of me downloading the la…

Fast enough depends what you are doing. Models down around 8B params will fit on the card, Ollama can spill out though so if you need more quality and can tolerate the latency bigger models like the 30B MoE might be good. I don't have much experience with Qwen3 but Qwen2.5 coder 7b and Gemma3 27b are examples of those two paths that I've used a fair amount.

these 0.5 and 0.6B models etc. are _fantastic_ for using as a draft model in speculative decoding. lm studio makes this super easy to do - i have it on like every model i play with now my concern on these models though unfortunately is it seems like architectures very a bit so idk how it'll work

Spec decoding only depends on the tokenizer used. It's transfering either the draft token sequence or at most draft logits to the main model.

Could be an lm studio thing, but the qwen3-0.6B model works as a draft model for the qwen3-32B and qwen3-30B-A3B but not the qwen3-235B-A22B model

Sonnet 3.7 non-reasoning got it right.

I'll think this through step by step. When you place a coin in a cup and slam it upside-down on a glass table, the coin will be between the table surface and the cup. When you look at the reflection in the mirror beneath the table, you're seeing the bottom side of the coin through the glass. Since the mirror shows heads, you're seeing the heads side of the coin reflected in the mirror. In a mirror, the image is reversed left-to-right, but the "heads" and "tails" sides of a coin would not be flipped in this reflection - you'd still recognize heads as heads. If you take away both the cup and the mirror, you'll see the opposite side of the coin compared to what you saw in the mirror. Since the mirror showed heads, you'll see tails when looking directly at the coin from above the table.
