How does GLM-5.1 compare?
Detailed Breakdown
Energy Consumption
GLM-5.1 improves on GLM-5 with stronger coding and reasoning, reaching 94.6% of Claude Opus 4.6's coding performance. At ~1.3 Wh per query, it continues to run entirely on Huawei Ascend chips — demonstrating viable NVIDIA-independent AI at the frontier. MIT licensed.
Power Source & Carbon
Runs on Huawei Ascend 910B chips in Chinese data centres.
About GLM-5.1
GLM-5.1 is an open-source text and chat model from Zhipu AI, released in March 27, 2026, that runs well below the category average for energy consumption at 1.3 Wh per query. Because its weights are publicly available, it can be self-hosted on any infrastructure — meaning its carbon footprint depends entirely on where and how you choose to run it. At 744B parameters, it 94.6% of claude opus 4.6 coding performance — huawei ascend trained.
These figures are estimates derived from hardware specifications and API benchmarks — Zhipu AI has not published official energy data for GLM-5.1. Actual consumption may vary significantly depending on batching, quantisation, and infrastructure optimisations that we cannot observe from outside.

Calculate My ComputeFrequently Asked Questions
How much energy does GLM-5.1 use per query?
Each GLM-5.1 query consumes approximately 1.3 Wh of energy. This is 4x more than a traditional Google search (~0.3 Wh).
What is GLM-5.1's carbon footprint?
Based on the carbon intensity of Zhipu AI Cloud (China), each query produces approximately 0.72 g of CO2. The grid in this region has a carbon intensity of 550 g CO2/kWh with 30% renewable energy.
How much water does GLM-5.1 use?
Each query consumes approximately 5 mL of water, primarily used for cooling the data centers that process the request.
How does GLM-5.1 compare to a Google search?
A GLM-5.1 query uses 4x more than a Google search in terms of energy. A Google search uses approximately 0.3 Wh, while GLM-5.1 uses 1.3 Wh.
