Speeds are estimates for a single request — one conversation at a time — calculated from memory bandwidth, model size and quantisation. Real throughput varies with the inference runtime and its version. Figures published by hardware vendors measure many simultaneous requests and are much higher.

The extremes

The ten fastest GPUs that run Tri-21B

Ranked by estimated tokens per second, newest card first where speeds tie. Because generation is bound by memory bandwidth, this ordering follows bandwidth rather than any gaming benchmark.

The smallest GPUs that still run Tri-21B

The cheapest route in, by memory capacity. A tight fit runs the model but leaves nothing spare for a longer conversation.

What the numbers mean

What it takes to run this model

Minimum card

Xeon Phi 7120P

Memory needed

13.2 GB

Fastest

163 tok/s

With 20.7B parameters, Tri-21B lands in the range a serious desktop card can handle once the weights are compressed. 241 of the cards we track can run it.

The smallest card that holds it is the Xeon Phi 7120P with 16 GB, running it at Q4_K_M and producing around 10.8 tokens per second.

A B200 is the fastest we calculate for it: about 163 tokens per second, from 8,000 GB/s of memory bandwidth.

Where it came from

Tri-21B was published by Trillion Labs, in Korea (Republic of), in August 2025. It comes out of industry.

It works in Language, and is recorded as doing language modeling/generation, Question answering, Code generation, Quantitative reasoning.

The weights are published, so it can be downloaded and run on your own hardware indefinitely, offline, with no account attached. It is published under the trillionlabs organisation on Hugging Face.

Understanding the speeds

Across every card that can run it, the middle of the range is about 21.1 tokens per second, and 198 of them clear the ten tokens per second that roughly matches reading speed.

Being dense, it reads all of itself per token, which is why the ordering by speed below follows the ordering by memory bandwidth so closely.

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.

What went into building it

Producing it required around 3 × 10²³ FLOP of arithmetic, which is a statement about the training budget rather than about inference.

Around 2,300,000,000,000 tokens went into training it.

Step by step

How to choose a GPU for Tri-21B

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

01

Read the memory figure first

Every card here has been checked against Tri-21B — around 13.2 GB at Q4_K_M. Capacity is the gate — a card either holds it or it does not.
02

Decide how long your conversations run

Set the context to what you will actually use. The cache grows with the conversation, and it is the usual reason Tri-21B stops fitting a card that seemed fine.
03

Decide how much compression you will accept

Each card runs the least-compressed copy it can hold — Q4_K_M on the smallest card that fits. Setting a floor drops the cards that only manage Tri-21B by squeezing it further than you would want.
04

Sort by speed

The speed ordering for Tri-21B is effectively an ordering by memory bandwidth, which is why the B200 tops it at 163 tok/s.
05

Look at the headroom, not just the fit

The fit column separates cards that just manage Tri-21B from those with room to spare. Buy for the second if the context might grow.
06

Open the card you have settled on

Each card page repeats this sweep for every model we hold. It answers what else the hardware is good for, beyond Tri-21B.

Answers

Tri-21B — common questions

Can I run Tri-21B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q6_K, using about 18.1 GB and generating roughly 39.8 tokens per second — a tight fit.

Is Tri-21B open source?

Its weights are published, so Tri-21B 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.

How many parameters does Tri-21B have?

Tri-21B has 20.7B parameters. 20.73B. 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 Tri-21B?

Tri-21B was published by Trillion Labs, based in Korea (Republic of), categorised as industry.

When was Tri-21B released?

Tri-21B was published in August 2025.

What is Tri-21B used for?

Tri-21B works in Language, and is recorded as handling language modeling/generation, Question answering, Code generation, Quantitative 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.

Where can I download Tri-21B?

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

How much compute was used to train Tri-21B?

Around 3 × 10²³ FLOP. 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.

Can I run Tri-21B if it does not fit in my GPU?

Only by offloading, which is usually a false economy: the part in system memory drags the whole thing down — the nearest miss we calculate is short by 2.4 GB. Our figures for Tri-21B assume it is fully resident.

Would two GPUs run Tri-21B faster?

Capacity adds across cards; throughput does not. Since 241 of the cards we track already hold Tri-21B on their own, a second card is rarely the answer here.

Why does the quantisation differ between cards for Tri-21B?

A larger card holds a more accurate copy. Across the cards that run Tri-21B, 4 compression levels are used; the floor control above pins it to one.

How accurate are these Tri-21B speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 98–262 tok/s on the B200, for instance. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

What GPU do I need to run Tri-21B?

The smallest card in our catalogue that holds Tri-21B is the Xeon Phi 7120P, with 16 GB of memory. It runs the model at Q4_K_M using about 13.2 GB, and produces roughly 10.8 tokens per second. 241 cards in total can run it.

How fast is Tri-21B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 163 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 198 of the cards that can run Tri-21B clear that.

How much VRAM does Tri-21B need?

About 13.2 GB at Q4_K_M compression, 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.

Can I run Tri-21B on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q4_K_M, using about 13.2 GB and generating roughly 53.3 tokens per second — a tight fit.
