OpenDiLoCo 150M
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.

"We conduct various experiments using a model with 150 million parameters on a language modeling task using the C4 dataset (Raffel et al., 2019). "
"The hyperparameters are consistent with DiLoCoacross experiments: an inner learning rate of 4e−4, 1,000 warm-up steps, 0.1 weight decay, a batch size of 512, a sequence length of 1,024, a learning rate for the Nesterov outer optimizer of 0.7, and Nesterov momentum of 0.9. Similarly, we run the experiments for a total of 88,000 steps." 512*1024*88000=46137344000
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.
- Training compute
- 4.2 × 10¹⁹ FLOP
- How it was established
- Operation counting
6ND = 6 FLOP / token / parameter * 150*10^6 parameters * 46137344000 tokens [see dataset size notes] = 4.152361e+19 FLOP

What the numbers mean
Background
OpenDiLoCo 150M was published by Prime Intellect, in United States of America, in July 2024. industry is the category the publisher falls under.
It works in Language, and is recorded as doing language modeling/generation, Question answering.
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
How it was trained
Training it took roughly 4.2 × 10¹⁹ FLOP of computation — a measure of what producing the model cost, not of how fast it answers.
Answers
OpenDiLoCo 150M — common questions
What GPU do I need to run OpenDiLoCo 150M?
None. OpenDiLoCo 150M 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 OpenDiLoCo 150M open source?
No. OpenDiLoCo 150M has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does OpenDiLoCo 150M have?
OpenDiLoCo 150M has 150M parameters. "We conduct various experiments using a model with 150 million parameters on a language modeling task using the C4 dataset (Raffel et al., 2019). ". 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 OpenDiLoCo 150M?
OpenDiLoCo 150M was published by Prime Intellect, based in United States of America, categorised as industry.
When was OpenDiLoCo 150M released?
OpenDiLoCo 150M was published in July 2024. 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 OpenDiLoCo 150M used for?
OpenDiLoCo 150M works in Language, and is recorded as handling language modeling/generation, Question answering. 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.
How much compute was used to train OpenDiLoCo 150M?
Around 4.2 × 10¹⁹ 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.
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.
