Closed weights Inception Labs 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.

Domain
Language
Task
Language modeling/generation, Code generation

Size

How large the model is and how much data it was trained on. Parameters are the figure that decides whether it fits on a given graphics card.

Training data
tokens

"The overall model is trained on the order of trillions of tokens."

The training run

What it physically took to train: which chips, how many, for how long, and what that drew from the wall.

Training hardware
NVIDIA H100 SXM5 80GB

What the numbers mean

Where it came from

Mercury Coder Small was published by Inception Labs, in the country recorded as United States of America, during June 2025. The category the publisher falls under is industry.

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

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

Answers

Mercury Coder Small — common questions

01

Mercury Coder Small— 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. 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

Mercury Coder Small— 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.

03

Mercury Coder Small— is it open source?

No. Its weights have not been published, so it exists only as a service controlled by its owner.

04

Mercury Coder Small— how many parameters does it have?

No parameter count has been published for it, which is why no memory or speed figure appears on this page.

05

Mercury Coder Small— who created it?

It was published by Inception Labs, based in United States of America, an organisation categorised as industry.

06

Mercury Coder Small— when was it released?

It was published in June 2025.
