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 for CodeGen-Mono 16.1B

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 CodeGen-Mono 16.1B

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

P102-101

Memory needed

8.6 GB

Fastest

210 tok/s

CodeGen-Mono 16.1B is small enough at 16.1B parameters that hardware is rarely the obstacle — 306 of the cards we track can run it, including cards several years old.

The smallest card that holds it is the P102-101 with 10 GB, running it at Q3_K_M and producing around 19.3 tokens per second.

The quickest result comes from a B200 at around 210 tokens per second — its 8,000 GB/s of bandwidth is what buys that.

Background

CodeGen-Mono 16.1B was published by Salesforce, in United States of America, in February 2023. The organisation is categorised as industry.

It works in Language, and is recorded as doing code generation, Code autocompletion.

Because its weights were released, nothing about running it depends on a provider staying available — it is yours once downloaded.

Reading the throughput figures

Half the cards that hold it manage more than 19.6 tokens per second, and 259 exceed reading speed outright.

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.

Without the attention layout on record, the memory column is an approximation. It is close enough to choose hardware by, and least reliable at long context.

Training and provenance

The training set ran to roughly 71,700,000,000 tokens.

Step by step

How to choose a GPU for CodeGen-Mono 16.1B

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

01

Start from the memory column

Every card here has been checked against CodeGen-Mono 16.1B — around 8.6 GB at Q3_K_M. Capacity is the gate — a card either holds it or it does not.
02

Match the context to your actual use

The conversation occupies memory too, and grows as it goes. Set the slider to the length you expect: at long context CodeGen-Mono 16.1B can slip off a card that handles short questions easily.
03

Choose how far you will compress it

Compression is what makes CodeGen-Mono 16.1B fit smaller cards, at some cost in accuracy — Q3_K_M on the smallest card that fits. A minimum quality removes the ones that go too far.
04

Compare tokens per second, not specifications

The speed ordering for CodeGen-Mono 16.1B is effectively an ordering by memory bandwidth, which is why the B200 tops it at 210 tok/s.
05

Look at the headroom, not just the fit

Tight means CodeGen-Mono 16.1B loads and works, with no room to raise the context later. Comfortable means you can. The difference matters more than a few tokens per second.
06

Open the card you have settled on

Every card name links to its own page, which runs the same calculation across the whole model catalogue. Worth a look before buying for CodeGen-Mono 16.1B alone — a card is usually bought for more than one model.

Answers

CodeGen-Mono 16.1B — common questions

Can I run CodeGen-Mono 16.1B 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 3.2 GB. Our figures for CodeGen-Mono 16.1B assume it is fully resident.

Would two GPUs run CodeGen-Mono 16.1B faster?

Two cards buy memory rather than speed. That matters for CodeGen-Mono 16.1B only if one card cannot hold it — 306 can, so a second adds little.

Why does the quantisation differ between cards for CodeGen-Mono 16.1B?

Because capacity varies, so does how hard CodeGen-Mono 16.1B has to be squeezed — 5 distinct levels appear in the table above. Set a minimum quality to compare at one.

How accurate are these CodeGen-Mono 16.1B speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 126–337 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 CodeGen-Mono 16.1B?

The smallest card in our catalogue that holds CodeGen-Mono 16.1B is the P102-101, with 10 GB of memory. It runs the model at Q3_K_M using about 8.6 GB, and produces roughly 19.3 tokens per second. 306 cards in total can run it.

How fast is CodeGen-Mono 16.1B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 210 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 259 of the cards that can run CodeGen-Mono 16.1B clear that.

How much VRAM does CodeGen-Mono 16.1B need?

About 8.6 GB at Q3_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 CodeGen-Mono 16.1B on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q4_K_M, using about 10.4 GB and generating roughly 55.4 tokens per second — a tight fit.

Can I run CodeGen-Mono 16.1B on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q6_K, using about 14.2 GB and generating roughly 43.2 tokens per second — a tight fit.

Can I run CodeGen-Mono 16.1B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 17.9 GB and generating roughly 35.3 tokens per second — a comfortable fit.

Is CodeGen-Mono 16.1B open source?

Its weights are published, so CodeGen-Mono 16.1B 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 CodeGen-Mono 16.1B have?

CodeGen-Mono 16.1B has 16.1B parameters. 16.1B 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.

Who created CodeGen-Mono 16.1B?

CodeGen-Mono 16.1B was published by Salesforce, based in United States of America, categorised as industry.

When was CodeGen-Mono 16.1B released?

CodeGen-Mono 16.1B was published in February 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 CodeGen-Mono 16.1B used for?

CodeGen-Mono 16.1B works in Language, and is recorded as handling code generation, Code autocompletion. 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 CodeGen-Mono 16.1B?

The weights for CodeGen-Mono 16.1B are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.
