Closed weights iFlytek 70B parameters March 2025

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

Spark-X1 was published by iFlytek, in China, in March 2025. It comes out of industry.

It works in Language, Mathematics, and is recorded as doing language modeling/generation, Chat, Mathematical reasoning.

Its weights were never published, so it can only be reached through its provider. No graphics card changes that.

Answers

Spark-X1 — common questions

01

What is Spark-X1 used for?

Spark-X1 works in Language, Mathematics, and is recorded as handling language modeling/generation, Chat, Mathematical reasoning. 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.

02

What GPU do I need to run Spark-X1?

None. Spark-X1 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.

03

Is Spark-X1 open source?

The licensing for Spark-X1 was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.

04

How many parameters does Spark-X1 have?

Spark-X1 has 70B 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.

05

Who created Spark-X1?

Spark-X1 was published by iFlytek, based in China, categorised as industry.

06

When was Spark-X1 released?

Spark-X1 was published in March 2025.
