What the numbers mean

Hardware requirements in practice

Minimum card

Tesla C1080

Memory needed

3.2 GB

Fastest

1,129 tok/s

Granite-4.0-H-Micro reaches a parameter count of 3B. That is small enough that hardware is rarely the obstacle, including on cards several years old. The number of cards we track that can run it: 818.

The entry point is Tesla C1080, with a memory capacity of 4 GB, running it at a compression of Q6_K and producing around 17.9 tokens per second.

The quickest result comes from B200, generating roughly 1,129 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

About this model

Granite-4.0-H-Micro was published by IBM, in the country recorded as United States of America, during October 2025. The publishing organisation is categorised as industry.

It works in the domain of Language, and is recorded as performing the task of language modeling/generation, Question answering, Text summarization, Text classification, Retrieval-augmented generation, Code generation.

Published weights mean the model runs on your machine rather than someone else's, which is what makes the hardware question below answerable at all. On Hugging Face it is published under the organisation ibm-granite.

How fast it runs, and why

Half the cards that hold it manage more than 35.8 tokens per second. Exceeding reading speed outright: 780 of them.

Every weight participates in every token here, so bandwidth is the whole story: the ranking below is effectively a ranking of memory throughput.

Its internal architecture is not on file, so memory is approximated from the parameter count and marked accordingly. Expect the real figure to differ, more so at long context.

Training and provenance

Producing it required arithmetic totalling around 3.2 × 10²³ FLOP, on hardware recorded as NVIDIA GB200. That figure measures what producing the model cost, and has no bearing on how fast it answers.

Step by step

How to choose a GPU for Granite-4.0-H-Micro

The table above has already assessed every card we hold specifications for against this model. Getting to your answer takes six steps.

01

Check what it needs before anything else

Start from what it actually needs, which is the requirement of Granite-4.0-H-Micro, needing around 3.2 GB at a compression of Q6_K. Capacity is the gate — a card either holds it or it does not.
02

Decide how long your conversations run

The conversation occupies memory too, and grows as it goes. Set the slider to the length you expect, because at long context a card that handles short questions easily can be dropped by Granite-4.0-H-Micro.
03

Choose how far you will compress it

The quantisation column varies by card, because a bigger card holds a more accurate copy, reaching a compression of Q6_K on the smallest card that fits. Setting a minimum quality drops the cards that only manage it by squeezing further than you would want, and holds the comparison at one level.
04

Compare tokens per second, not specifications

The speed ordering is effectively an ordering by memory bandwidth, for Granite-4.0-H-Micro. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 1,129 tok/s.
05

Check the fit verdict before buying

The fit column separates cards that just manage it from those with room to spare, in the case of Granite-4.0-H-Micro. Comfortable means you can grow the context later. That difference matters more than a few tokens per second, so buy for comfortable if you expect to.
06

See what else that card runs

Every card name links to its own page, which runs the same calculation across the whole model catalogue. A card is usually bought for more than one model, so it is worth a look before buying for Granite-4.0-H-Micro.

Granite-4.0-H-Micro— is it open source?

Its weights are published, so it can be downloaded and run on your own hardware. Note that open weights is not the same as open source in the full sense — it says nothing about the training data, the training code, or the commercial terms attached.

Granite-4.0-H-Micro— how many parameters does it have?

It has a parameter count of 3B. dense hybrid model with 3B 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.

Granite-4.0-H-Micro— who created it?

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

Granite-4.0-H-Micro— when was it released?

It was published in October 2025.

Granite-4.0-H-Micro— what is it used for?

It works in the domain of Language, and is recorded as handling the task of language modeling/generation, Question answering, Text summarization, Text classification, Retrieval-augmented generation, Code generation. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

Granite-4.0-H-Micro— where can I download it?

Its weights are published on Hugging Face, under the organisation ibm-granite. We do not host model files — this site calculates what hardware is needed to run them.

Granite-4.0-H-Micro— how much compute was used to train it?

Training consumed around 3.2 × 10²³ FLOP, on hardware recorded as NVIDIA GB200. 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.

Granite-4.0-H-Micro— can I run it if it does not fit in my GPU?

It can be split between the card and system memory, but it generates painfully slowly that way. Every figure here assumes the whole model is resident on the card.

Granite-4.0-H-Micro— would two GPUs run it faster?

Capacity adds across cards; throughput does not. The number of cards already holding it on their own: 818. So a second card is rarely the answer here.

Granite-4.0-H-Micro— why does the quantisation differ between cards?

Because capacity varies, so does how hard it has to be squeezed. The number of distinct levels in the table above: 2. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

Granite-4.0-H-Micro— how accurate are these speed estimates?

These are estimates with real error bars, and any of them could reasonably land anywhere in its published range depending on which runtime you use. The fastest result here: 678–1,807 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

Granite-4.0-H-Micro— what GPU do I need to run it?

The smallest card in our catalogue that holds it is Tesla C1080, with a memory capacity of 4 GB. It runs the model at a compression of Q6_K using about 3.2 GB, and produces roughly 17.9 tokens per second. The number of cards able to run it in total: 818.

Granite-4.0-H-Micro— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 1,129 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and the number of cards clearing that: 780.

Granite-4.0-H-Micro— how much VRAM does it need?

It needs about 3.2 GB at a compression of Q6_K, which is what the smallest card that runs it uses. Less compression needs more: the figures in the memory column above are recalculated for each card, because each one holds the least-compressed version it can.

Granite-4.0-H-Micro— can I run it on a GPU holding 8 GB?

Yes. The card CMP 170HX 8 GB, holding 8 GB, runs it at a compression of Q8_0, using about 3.9 GB and generating roughly 210 tokens per second. The fit is comfortable.
