Entry price
Free plan available, paid tiers above
Biggest pro
Open weights under a permissive MIT license; download, fine-tune, and self-host freely
Biggest con
Running the full 753B model locally needs serious GPU hardware
TL;DR - GLM-5.2
- Open-weights coding LLM from Z.ai (formerly Zhipu AI), MIT-licensed and free to self-host from Hugging Face.
- 753 billion parameters with a 1-million-token context window, tuned for long-horizon autonomous coding.
- Scores 62.1 on SWE-bench Pro, ahead of GPT-5.5 (58.6), at about one-sixth the cost.

How GLM-5.2 Compares to Competitors
This tool is cheaper than most proprietary autonomous coding platforms, which often charge per-seat or usage-based fees at higher rates. However, it is pricier than self-hosting open source alternatives, though the 1M token context and managed infrastructure likely justify the cost compared to leading enterprise coding assistants.
How GLM-5.2's pricing compares
At $10/mo, GLM-5.2 is mid-range of its 5 direct competitors ($9 to $24/mo across the set).
