Frequently Asked Questions about GLM-5.1

How much does the GLM-5.1 API cost per 1M tokens?+

GLM-5.1 by Zhipu AI is priced at $0 per 1M input tokens and $0 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0 per 1M tokens, and asynchronous Batch API requests receive a 0% discount.

Should I use a $20/month subscription or the GLM-5.1 pay-as-you-go API?+

A flat $20/month consumer subscription is predictable for daily interactive chat and manual coding. However, if you are building software, running automated workflows, or sending low-to-moderate volume with prompt caching enabled, the pay-as-you-go API is typically far more cost-effective and offers higher rate limits without manual UI caps.

How many words and pages fit in GLM-5.1's context window?+

GLM-5.1 features a 200K tokens context window, which equals approximately 150,000 English words or ~400 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 16,384 tokens.

Can I run GLM-5.1 locally on my own GPU (Open Weights)?+

Yes, GLM-5.1 (280B MoE) releases open weights that can be self-hosted locally or on private cloud GPUs using vLLM, Ollama, SGLang, or llama.cpp.

Does Zhipu AI train on data sent to the GLM-5.1 API, and is commercial use allowed?+

100% Isolated when self-hosted on private GPUs or VPC. License tier: Open-Weights Research & Commercial License. Full commercial ownership of generated outputs. Supported deployment channels include: Self-Hosted GPU (vLLM / Ollama), Private VPC, or Managed Serverless API.

How does GLM-5.1 perform on coding and reasoning benchmarks?+

GLM-5.1 achieves a composite Intelligence Index of 89/100, scoring 63% on SWE-bench Verified, 70% on GPQA Diamond, 85.5% on MMLU-Pro, and 1410 pts on Chatbot Arena Elo.

What is GLM-5.1 best used for?+

GLM-5.1 is best suited for: souverain codage agents, automatisé pull request validation, et d'entreprise logiciel modernisation. Assessment: le heavyweight ouvert champion pour développeur tooling et autonome ingénierie logicielle.
