Seed-1.6-Thinking
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.

What the numbers mean
Where it came from
Seed-1.6-Thinking was published by ByteDance, in China, in June 2025. industry is the category the publisher falls under.
It works in Multimodal, Language, Vision, and is recorded as doing language modeling/generation, Vision-language generation.
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
What went into building it
The reason it appears in this catalogue at all is sOTA improvement.
Answers
Seed-1.6-Thinking — common questions
What is Seed-1.6-Thinking used for?
Seed-1.6-Thinking works in Multimodal, Language, Vision, and is recorded as handling language modeling/generation, Vision-language generation. A model can carry several of each, so these are the areas it was built for rather than a limit on what it will attempt.
What GPU do I need to run Seed-1.6-Thinking?
None. Seed-1.6-Thinking 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 Seed-1.6-Thinking open source?
No. Seed-1.6-Thinking has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does Seed-1.6-Thinking have?
Seed-1.6-Thinking has 230B parameters. Model has 230B parameters total, with 23B active parameters (sparse MoE setting). 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 Seed-1.6-Thinking?
Seed-1.6-Thinking was published by ByteDance, based in China, categorised as industry.
When was Seed-1.6-Thinking released?
Seed-1.6-Thinking was published in June 2025.

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.
