GLM-5.1 offers a free tier — you might not need to pay at all!
Perfect for trying out GLM-5.1 without spending anything
💡 Pro tip: Start with the free tier to test if GLM-5.1 fits your workflow before upgrading to a paid plan.
per month
Don't overpay for features you won't use. Here's our recommendation based on your use case:
Most AI tools, including many in the automation & workflows category, offer special pricing for students, teachers, and educational institutions. These discounts typically range from 20-50% off regular pricing.
• Students: Verify your student status with a .edu email or Student ID
• Teachers: Faculty and staff often qualify for education pricing
• Institutions: Schools can request volume discounts for classroom use
Most SaaS and AI tools tend to offer their best deals around these windows. While we can't guarantee GLM-5.1 runs promotions during all of these, they're worth watching:
The biggest discount window across the SaaS industry — many tools offer their best annual deals here
Holiday promotions and year-end deals are common as companies push to close out Q4
Tools targeting students and educators often run promotions during this window
Signing up for GLM-5.1's email list is the best way to catch promotions as they happen
💡 Pro tip: If you're not in a rush, Black Friday and end-of-year tend to be the safest bets for SaaS discounts across the board.

Large language model and AI assistant developed by Alibaba, offering chat-based AI capabilities.

GLM-5.1 is a large language model in the GLM-5 family released by zai-org (Z.ai), distributed as open weights on Hugging Face. It targets complex systems engineering and long-horizon agentic tasks such as multi-step coding, reasoning, and tool use. The model uses a Mixture-of-Experts architecture with 744B total parameters and 40B active per forward pass. Z.ai also offers a managed API on the Z.ai API Platform for users who prefer not to self-host.
The model weights are free to download from Hugging Face, so there is no licensing fee to run it yourself. Real costs come from compute: serving a 744B-parameter MoE model requires multi-GPU infrastructure, typically high-VRAM datacenter GPUs. If you prefer a hosted endpoint, Z.ai offers a paid managed API on the Z.ai API Platform (pricing listed there). Quantized variants accessible via Ollama or LM Studio can lower hardware requirements significantly.
On the published benchmarks, GLM-5 leads on HMMT Nov. 2025 (96.9 vs Gemini 3 Pro 93.0 and Claude Opus 4.5 91.7) and is competitive on AIME 2026 I (92.7) and SWE-bench Multilingual (73.3, ahead of Gemini 3 Pro's 65.0). It still trails frontier models on Humanity's Last Exam (30.5 vs Gemini 3 Pro 37.2) and GPQA-Diamond (86.0 vs 91.9–92.4). For open-source coding and agentic workloads, GLM-5 is the strongest contender Z.ai has shipped.
The Hugging Face card documents three primary paths. With vLLM, you run pip install vllm then vllm serve "zai-org/GLM-5" to expose an OpenAI-compatible endpoint on port 8000. SGLang supports a similar flow via python3 -m sglang.launch_server with --model-path "zai-org/GLM-5" on port 30000. For lighter use, Docker Model Runner (docker model run hf.co/zai-org/GLM-5), Ollama, or LM Studio with quantized variants work well on smaller hardware.
Yes. The chat template natively handles a tools field and emits structured tool calls inside <tool_call>...</tool_call> XML blocks, with arg_key/arg_value pairs for each parameter. The model is explicitly tuned for long-horizon agentic tasks, which is a stated focus of the GLM-5 release. Note that the format is custom XML rather than OpenAI's JSON function-calling schema, so you may need a small adapter when migrating existing OpenAI agent code.
