GLM-5.2

What GLM-5.2 is for

GLM-5.2 is a reasoning model: it spends output tokens working through a problem before answering, which makes it slower per useful word and better on problems that need the working shown. Z.ai released it in 2026-06 with a single 744B (40B active MoE) size under MIT, with a 128K context window. Budget for the extra tokens the thinking phase consumes. The catalogue records its strength as latest Z.ai frontier reasoning model (2026 mid-year).

Sizes and memory

Our catalogue does not carry a per-size memory breakdown for GLM-5.2. What it records instead is a floor of 256 GB and a recommended 512 GB for the default configuration. Until a per-size figure exists, treat those two numbers as the whole guidance rather than reading a size table that would have to be invented.

Hardware that runs GLM-5.2

Without a per-size memory figure there is no honest way to say which card holds GLM-5.2. Its recorded floor of 256 GB rules out every consumer card in our hardware guide, which tops out well below that.

What people use it for

The catalogue lists 3 recorded uses for GLM-5.2: frontier reasoning, agentic engineering, production agent deployment. It is tagged reasoning, thinking, agentic, MoE, frontier.

Where GLM-5.2 sits in the GLM family

Our catalogue holds 5 GLM entries. Ordered by release date, GLM-5.2 (2026-06) is the 5th of them, and the most recent. GLM-5 and GLM-5.1 carry the same recorded memory footprint, so choosing between those and this one is a question of behaviour rather than of hardware: GLM-5.2 is the one recorded here for latest Z.ai frontier reasoning model (2026 mid-year).

The MIT licence puts no usage ceiling on it, which matters if the thing you are building has users. That is the practical difference between this and a vendor community licence.

Context window: 128K

128K tokens is roughly 96,000 words at the usual ratio, which is a small repository or a whole book. Two cautions come with a window this size: the KV cache at full length can rival the weights for memory, and models rarely use the far end of their advertised context as well as they use the near end. Treat it as headroom, not as a promise.

How to run GLM-5.2 locally

Our catalogue does not record registry tags, so look the current tag up in the Ollama library or on Hugging Face before pasting these. The commands below are the shape of the workflow, not a copy-and-paste recipe.

Option 1: Ollama (simplest)

# find the tag for GLM-5.2 at ollama.com/library
ollama run <tag>

Option 2: Mullama (production)

mullama pull <tag>
mullama run <tag>

Option 3: llama.cpp (CLI)

# download a GGUF from Hugging Face, searching for "GLM-5.2 GGUF"
./llama-cli -m model.Q4_K_M.gguf -p "Hello, AI!"

Option 4: Python with Mullama or llama-cpp-python

from mullama import Model, Context
model = Model.load("model.Q4_K_M.gguf", n_gpu_layers=99)
ctx = Context(model, n_ctx=4096)
print(ctx.generate("Hello, AI!", 256))
