GLM 5.2 is now in Notion's model picker — and its 1M context window changes what Custom Agents can actually process

GLM 5.2 (Z.ai / Zhipu AI) arrived in Notion's Custom Agents model picker on June 17, 2026 — the first open-weight model in the picker. The practical differentiator for PMs is its 1M-token context window, which lets a single agent run ingest a full sprint database, spec documents, and a changelog without truncation. The article explains what the model is (744B MoE, 40B active, MIT license), defines its lane in the picker vs. Auto mode, walks through a 5-step weekly sprint report setup with a copy-paste instruction block, and documents five gotchas — including the undocumented Notion credit multiplier, which remains the key unknown before committing to it at scale.
