Quality is the published perplexity delta against f16 weights. Max context assumes an f16 KV cache; q8_0 roughly doubles it. This model uses multi-head latent attention, so its cache is a compressed latent rather than full K and V.
How to run it
$ ollama pull glm-4.7-flash:latest $ OLLAMA_CONTEXT_LENGTH=8192 \ ollama run glm-4.7-flash:latest
The default. One binary, a model registry, an OpenAI-compatible port. More on Ollama.
01Download is 17.5 GB. Keep it on an SSD — a first load off a spinning disk takes minutes.
02macOS caps what the GPU may wire down at about 96.0 GB of 128 GB. Raising it with iogpu.wired_limit_mb is possible, and risky.
03There is room to go to the model's full 198K context on this card.
