Closed weights SenseTime 180B parameters April 2023

No estimate

No hardware requirements for this model

The weights for this model have not been published, so it cannot be downloaded or run on your own hardware at any size. It is reachable only through its provider, and no graphics card changes that.

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

“Over the course of five years, SenseTime has built SenseCore, a leading AI infrastructure with 27,000 GPUs, capable of delivering a total computational power of 5,000 petaflops” Assuming they used this entire cluster with 30 days of training (rough average of frontier model training times since 2016), 30% utilization rate: 5000e15 * 0.3 * 30 * 24 * 60 * 60 = 3.89e24 FLOP.

What the numbers mean

Where it came from

SenseChat was published by SenseTime, in Hong Kong, in April 2023. It comes out of industry.

It works in Language, and is recorded as doing chat, Language modeling/generation.

This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.

How it was trained

Producing it required around 3.9 × 10²⁴ FLOP of arithmetic, which is a statement about the training budget rather than about inference.

Its inclusion criterion is training cost.

Answers

SenseChat — common questions

01

How many parameters does SenseChat have?

SenseChat has 180B parameters. https://www.thepaper.cn/newsDetail_forward_22639611 Translation: "SenseTime launched the "SenseNova" large model system, which includes natural language generation, image generation services, pre-labeling for perception models, and model development. The "SenseChat" application platform, powered by a 180-billion parameter Chinese language model, supports ultra-long text comprehension and offers capabilities such as question answering, understanding, and generation in Chinese." Link says "hundreds of billions" but the more precise number above seems more credible. 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.

02

Who created SenseChat?

SenseChat was published by SenseTime, based in Hong Kong, categorised as industry.

03

When was SenseChat released?

SenseChat was published in April 2023. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

04

What is SenseChat used for?

SenseChat works in Language, and is recorded as handling chat, Language modeling/generation. These are the areas it was designed around; they describe intent rather than a hard boundary.

05

How much compute was used to train SenseChat?

Around 3.9 × 10²⁴ FLOP. 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.

06

What GPU do I need to run SenseChat?

None. SenseChat 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.

07

Is SenseChat open source?

No. SenseChat has not had its weights published, so it exists only as a service controlled by its owner.

This page starts from the model. If you already own a card and want to know everything it will run, start from the hardware instead.
