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.

Training compute
The arithmetic performed to train the model, measured in floating-point operations. It is a measure of what the training run cost, not of how fast the finished model answers you.

Estimate using hardware: "Granite.13b.v1 used 256 A100 GPUs for 1056 hours and 120 TFLOPs. Granite.13b.v2 was trained on the same infrastructure for an additional 1152 hours with 120 TFLOPS, bringing the total to 2208 hours" Seems like 120 TFLOPS is the output per GPU after utilization, though they don't explicitly explain that part. That's 38% utilization. 256 * 2208 * 3600 * 120 TFLOPS = 2.44e23 Using 6ND: "The second version of the granite.13b models leverages an updated base model train…

What the numbers mean
Background
Granite 13B was published by IBM, in United States of America, in November 2023. The organisation is categorised as industry.
It works in Language, and is recorded as doing chat, Language modeling/generation, Question answering, Text summarization.
Its weights were never published, so it can only be reached through its provider. No graphics card changes that.
How it was trained
Training it took roughly 2.4 × 10²³ FLOP of computation, on NVIDIA A100 — a measure of what producing the model cost, not of how fast it answers.
The training set ran to roughly 2,500,000,000,000 tokens.
Answers
Granite 13B — common questions
How much compute was used to train Granite 13B?
Around 2.4 × 10²³ FLOP, on NVIDIA A100. 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.
What GPU do I need to run Granite 13B?
None. Granite 13B 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 Granite 13B open source?
No. Granite 13B has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does Granite 13B have?
Granite 13B has 13B parameters. 13 billion. 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 Granite 13B?
Granite 13B was published by IBM, based in United States of America, categorised as industry.
When was Granite 13B released?
Granite 13B was published in November 2023. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
What is Granite 13B used for?
Granite 13B works in Language, and is recorded as handling chat, Language modeling/generation, Question answering, Text summarization. These are the areas it was designed around; they describe intent rather than a hard boundary.
The other direction
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.
