You can now Run GLM-5.3-Flash Locally! ✨
Hey guys, GLM-5.3-Flash can now be run locally in Unsloth Desktop! ✨
Run 3-bit on 128GB RAM or 1-bit on 100GB. The bigger ones are still uploading.
GLM-5.3-Flash (ox-alpha) rivals Claude Opus 4.8 on DeepSWE, coding & agentic benchmarks.

Please Unsloth make TQ1_0 I need fit on 96G
Does the MTP layer work? I tried loading them but it results in an error message saying nextm isn't implemented
Please Unsloth make TQ1_0 I need fit on 96G
Yes agreed please and thx
What type of speed are people getting with 128GB Macs?

Unsloth fork llama.cpp, 08-2026 pull
Default thinking runs ridiculously long, but 'low' seems okay so far
-mmap, -fit on
-b 4096 -ub 1024
full 1m ctx seems to be runnable
Major bottlneck 2ch DDR5, 4800mt/s.
At 108k context: PP 60-70, TG 6-7, rtx3090 gpus @100w /gpu, cpu @6threads 22%, DRAM use 118GB.
At 240k context: PP 8-11, TG 6
Increasing to 1M context drops it to a slog (why? until the ctx is actually filled, it should be fast... there must be a patch...)
Performance for this 176GB system is in same league as Minimax-M2.7, MiMo-2.5 and DeepSeek4-flash. All are so smart that it's hard to differentiate between them. GLM5.3 definitely up there - at these sizes the main productivity differences come from my degree of resonance and shared assumptions, the communication, the alignment with language.
Thank you for sharing your results.
