What it does
The problem areas the model was built for. A model can carry several of each.
- Domain
- Language
- Task
- Language modeling/generation, Question answering
Size
How large the model is and how much data it was trained on. Parameters are the figure that decides whether it fits on a given graphics card.
- Parameters
- 718B
- Training data
- tokens
a sparse LLM with 718 billion parameters 39B activated parameters
Training compute
The arithmetic performed to train the model, measured in floating-point operations. It is a measure of what the training run cost, not of how fast the finished model answers you.
- Training compute
- 3.1 × 10²⁴ FLOP
- How it was established
- Operation counting
Speculatively assuming they trained MoE model on the same amount of tokens as Pangu Ultra (13,2 T): 6 FLOP / parameter / token * 39 * 10^9 activated parameters * 13,2 * 10^12 tokens = 3.0888e+24 FLOP
The training run
What it physically took to train: which chips, how many, for how long, and what that drew from the wall.
- Training hardware
- Huawei Ascend 910B
- Chips used
- 6,000
- Hardware utilisation
- MFU 30.0%
- Power draw
- 4.7 MW
"Taking advantage of our model selection strategy and parallel computing system optimization, when training Pangu Ultra MoE, with performance comparable to DeepSeek R1 [10], we achieve a Model Flops Utilization (MFU) of 30.0% and Tokens Per Second (TPS) of 1.46M on 6K Ascend NPUs, compared to the baseline MFU of 18.9% and TPS of 0.61M on 4K Ascend NPUs."

What the numbers mean
What this model is
Pangu Ultra MoE was published by Huawei, in China, in May 2025. industry is the category the publisher falls under.
It works in Language, and is recorded as doing language modeling/generation, Question answering.
Its weights were never published, so it can only be reached through its provider. No graphics card changes that.
How it was trained
Producing it required around 3.1 × 10²⁴ FLOP of arithmetic, on Huawei Ascend 910B, which is a statement about the training budget rather than about inference.
Answers
Pangu Ultra MoE — common questions
What GPU do I need to run Pangu Ultra MoE?
None. Pangu Ultra MoE is a closed model — its weights were never published, so it cannot be downloaded or run on your own hardware at any price. It is reachable only through its provider.
Is Pangu Ultra MoE open source?
No. Pangu Ultra MoE has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does Pangu Ultra MoE have?
Pangu Ultra MoE has 718B parameters. a sparse LLM with 718 billion parameters 39B activated parameters. That figure is the total, and it is what decides how much memory the model needs — roughly half a gigabyte per billion at the compression most people use.
Who created Pangu Ultra MoE?
Pangu Ultra MoE was published by Huawei, based in China, categorised as industry.
When was Pangu Ultra MoE released?
Pangu Ultra MoE was published in May 2025.
What is Pangu Ultra MoE used for?
Pangu Ultra MoE works in Language, and is recorded as handling language modeling/generation, Question answering. These are the areas it was designed around; they describe intent rather than a hard boundary.
How much compute was used to train Pangu Ultra MoE?
Around 3.1 × 10²⁴ FLOP, on Huawei Ascend 910B. That measures what producing the model cost and says nothing about how quickly it answers once trained — inference speed comes from memory bandwidth, not from the training budget.
