Overview
About this model
GLM-5.2 marks a substantial leap in long-horizon task capability over its predecessor GLM-5.1 and, for the first time, delivers that capability on a solid 1M-token context. GLM-5.2's new capabilities include: Solid 1M Context: A solid 1M-token context that stably sustains long-horizon work Advanced Coding with Flexible Effort: Stronger coding capabilities with multiple thinking effort levels to balance performance and latency Improved Architecture: We propose IndexShare, which reuses the same indexer across every four sparse attention layers, reducing per-token FLOPs by 2.9× at a 1M context length. We also improve GLM-5.2’s MTP layer for speculative decoding, increasing the acceptance length by up to 20% Pure Open: An MIT open-source license — no regional limits, technical access without borders

FAQ
Common questions
- How much does the GLM-5.2 API cost?
- GLM-5.2 is $1.00 per 1M input tokens and $3.00 per 1M output tokens on EcoHash. That figure comes live from the EcoHash billing system, so the price shown on this page is the price you are billed — there is no separate list price to reconcile.
- GLM-5.2 vs gpt-oss-20b: which should I use?
- Both are language models on the same OpenAI-compatible EcoHash API, so moving between them is a change of model id and nothing else. GLM-5.2 has $1.00 per 1M input tokens and $3.00 per 1M output tokens. gpt-oss-20b has a 128K-token context window at $0.05 per 1M input tokens and $0.20 per 1M output tokens. Both prices come live from the EcoHash billing system; the comparison table on this page carries the current figures.
- Can I use GLM-5.2 commercially through EcoHash?
- EcoHash hosts GLM-5.2 under the model publisher's own licence and does not change its terms, so whether your use is permitted is decided by that licence — read it on the model publisher's own licence. The EcoHash Terms of Service additionally require you to comply with each model's licence and acceptable-use policy. Your EcoHash bill for API usage is separate from, and does not grant, any right under the model's licence.
