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.

On record

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.

Why it is tracked
SOTA improvement

Improves on hardware SOTA for similar problems Abstract: "We push the model scale to over 1 trillion parameters and implement it on solely 480 NVIDIA V100-32GB GPUs, in comparison with the recent SOTAs [11; 6] on 2048 TPU cores."

What the numbers mean

What this model is

M6-T was published by Alibaba, in China, in March 2021. industry is the category the publisher falls under.

It works in Multimodal, Language, Vision, and is recorded as doing chat, Image captioning.

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

Training and provenance

Training it took roughly 5.5 × 10²¹ FLOP of computation, on NVIDIA Tesla V100 DGXS 32 GB — a measure of what producing the model cost, not of how fast it answers.

The training set ran to roughly 111,800,000,000 tokens.

The reason it appears in this catalogue at all is sOTA improvement.

Answers

M6-T — common questions

01

What is M6-T used for?

M6-T works in Multimodal, Language, Vision, and is recorded as handling chat, Image captioning. These are the areas it was designed around; they describe intent rather than a hard boundary.

02

How much compute was used to train M6-T?

Around 5.5 × 10²¹ FLOP, on NVIDIA Tesla V100 DGXS 32 GB. 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.

03

What GPU do I need to run M6-T?

None. M6-T 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.

04

Is M6-T open source?

No. M6-T has not had its weights published, so it exists only as a service controlled by its owner.

05

How many parameters does M6-T have?

M6-T has 1T parameters. Table 5. Note model is sparse MoE with 960 experts; not all parameters are activated on the forward pass. 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.

06

Who created M6-T?

M6-T was published by Alibaba, based in China, categorised as industry.

07

When was M6-T released?

M6-T was published in March 2021. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

Looking at it from the other side?

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.
