this thing is a beast

I'm sitting with two 1080 ti's (22gb vram). Was daily driving Qwen_Qwen3.6-27B-IQ3_XS (bartowski, 12.7gb) and Qwen3.6-35B-A3B-Claude-4.7-Opus-Reasoning-Distilled.IQ4_XS (lordx64, 18.5gb) until today. Like i was not sure what is better. Just tried this one - Qwen3.6-35B-A3B-Claude-4.7-Opus-Reasoning-Distilled-APEX-I-Compact (16.8gb). And i must say - both MoE mentioned is not less capable for my fullstack project, than 27b model! But speed difference is like 3x (10 t/s and 30 t/s). PP is also night and day. Also while on IQ4_XS i was able to only utilize 131k context - on I-Compact it's possible to go for 196k (and probably more, just didn't test yet). So it's my new daily driver now.

yeah, for real. i used the others too but this one, the i-quality model full context (llama.cpp) used by hermes agent with continuous 50 t/s (compared to 24), excellent precision, excellent reasoning, zero tool call misses. Uses around 60GB of unified RAM, compared to 90+ GB of the others (q8_0) but with same or better quality.

This is the best Qwen 3.6 model by far.

Congrats mudler and many thanks!

Glad you enjoy! It's indeed my daily driver all around too. I'll keep pushing other MoE models quants as new releases pop up :)

which version would you recommend for a 16gb GPU?

Care to share what llama branch are you running it with or are you running the official build? I have a multig 1080ti rig too so I am curious

After all this praise, I tested the balanced version of this on my strix halo. It flies but I don't get consistent quality responses. I'm using llama.cpp image tag: server-vulkan-b8643. On cold start the responses seem fine, but if I resubmit the same query it can go off the rails. I often get different answers like "yes" vs "no" being complete opposite and sometimes the thinking gets stuck in infinite loop. I wonder if there's a kv cache issue, which might be llama specific. My test prompt was "what is the die in something like die cast, and the die in computer chips?" Everything works great on this setup with gemma 4 and many others.
