Closed weights OpenBMB (Open Lab for Big Model Base) 8B parameters June 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.

On record

Full specification

Everything on record for this model. Most of it describes how it was trained rather than how it runs — useful context for judging how much work went into it, and how it compares with models built at a different scale.

What the numbers mean

What this model is

MiniCPM-4-8B was published by OpenBMB (Open Lab for Big Model Base), in the country recorded as China, during June 2025.

It works in the domain of Language, and is recorded as performing the task of language modeling/generation, Code generation, Translation.

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

Answers

MiniCPM-4-8B — common questions

01

MiniCPM-4-8B— is it open source?

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

02

MiniCPM-4-8B— how many parameters does it have?

It has a parameter count of 8B. 8b. 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.

03

MiniCPM-4-8B— who created it?

It was published by OpenBMB (Open Lab for Big Model Base), based in China.

04

MiniCPM-4-8B— when was it released?

It was published in June 2025.

05

MiniCPM-4-8B— what is it used for?

It works in the domain of Language, and is recorded as handling the task of language modeling/generation, Code generation, Translation. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

06

MiniCPM-4-8B— what GPU do I need to run it?

None. This 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.
