Run commands

Ollama
ollama run glm-5.3-flash
LM Studio
lms get unsloth/GLM-5.3-Flash-GGUF # Then load quant UD-IQ1_S
Assumptions
- Estimate from memory bandwidth, not a benchmark. Decode speed uses 55–75% of peak bandwidth.
- KV cache is FP16. Engine overhead assumes llama.cpp (0.3 GB + 1% of the weights). Ollama is closer to 0.9 GB + 3%, LM Studio closer to 1 GB + 3%.
- 0.5 GB is reserved because the GPU also drives a display, then 5% is left free.
- Usable memory for this profile is 14.7 GB.
