Zhipu's GLM-5.3 was released as an open-weight model on Hugging Face — a runnable-locally option for bulk GTM classification/enrichment/drafting versus paying per API call. Exact commercial license terms are NOT independently verified.

## Notes

- Top of Hacker News (707 pts). An unsloth GGUF quant landed within hours (huggingface.co/unsloth/GLM-5.3-Flash-GGUF), so it is runnable locally now. Build-vs-buy signal. Caveat: "open-weight" ≠ commercially clean — verify the exact license clause before any brand-facing claim.
