How does this model fare?
I am curious how this model compares to others that are similar in size (e.g., q4 of MiniMax-M2.7, Deepseek Flash, etc). Anyone have any experience or feedback so far?
Thanks as always, unsloth!
Well its multimodal, and seems faster than minimax. I'm testing the Q8 of both for the record. The quality vibe I get is similarish to minimax? But again, multimodal, which is not something you'll use all the time but can be interesting to have.
Pd: I tried it at longer tasks and it tends to bug out whereas Minimax and Deepseek v4 flash dont. Shame, because it is substantially faster. But no good if its far more likely to loop on tasks
PPD: I tried Stepfun's 8_0 quant and it seems more stable than 8KXL here
Last week it ran like crap on llama.cpp and was all over the place. And speed was 20% slower than i expect from 3.5.
This week with the latest llama.cpp, it seems to be improved notably, now only 10% slower, but thinks too for too long ( i'm using LMstudio and have no 'reasoning slider' )
So, back to 3.5 for now..
I tried UD-Q4_K_XL and it was great up until about 90-100k context, then it starts hallucinating wildly. Complaining of Bengali characters in files (there were none) and repeatedly looping attempting to repair non-existent characters it claims to have inserted.
^-- based on that i would say model support is probably quite bugged
This model is supposed to handle large context better than the previous one.
switching to Stepflash' official quant improved things a bit but it still bugs out. Loops, etc.. Maybe I can try ramping up the repeat penalty, there's not a lot of guidance from the makers. I think its faster than minimax or Deepseek Flash, but buggier.
Real unfortunate.
I notice Step 3.7 is gradually running faster, so llama.cpp engine's support of it is improving.
It appears the reasoning level is set to high though.. and not toggle-able. Step 3.57Flash is not useable because reasoning level cannot be changed.
For me the problem are the failed tool calls that break workflows. At this point it happens way tol frequently, so my go-tos at this size are still Minimax 2.7 and deepseek flash
