MAI-DS-R1 TPS calculator
Each card below is assessed against this model at the context length and minimum quality you choose. Speed is an estimate for a single request, calculated from the card's memory bandwidth and the size of the model once compressed.

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.

What the numbers mean
The hardware side
At 671B parameters, MAI-DS-R1 is beyond what any single graphics card holds. Running it means either splitting it across several cards or renting hardware built for the job — 0 of the cards we track can hold it on their own, and all of them are datacentre parts.
Background
MAI-DS-R1 was published by Microsoft, in United States of America, in April 2025. industry is the category the publisher falls under.
It works in Language, and is recorded as doing language modeling/generation, Question answering, Quantitative reasoning, Code generation.
It is derived from DeepSeek-R1 rather than trained from scratch, which is the usual way a specialised model is produced.
The weights being open is what puts this page in the calculator rather than only in the catalogue: it is a model you can actually hold. It is published under the microsoft organisation on Hugging Face.
Step by step
How to choose a GPU for MAI-DS-R1
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 MAI-DS-R1. Capacity is the gate — a card either holds it or it does not.
-
02
Match the context to your actual use
Longer conversations cost memory on top of what the weights need. Move the slider to your real working length before trusting any row for MAI-DS-R1.
-
03
Choose how far you will compress it
Each card runs the least-compressed copy it can hold. Setting a floor drops the cards that only manage MAI-DS-R1 by squeezing it further than you would want.
-
04
Rank by throughput rather than spec sheet
The speed ordering for MAI-DS-R1 is effectively an ordering by memory bandwidth.
-
05
Look at the headroom, not just the fit
Tight means MAI-DS-R1 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
See what else that card runs
Following a card through to its own page shows every other model it can hold, which is the question that follows once MAI-DS-R1 is settled.
Answers
MAI-DS-R1 — common questions
How accurate are these MAI-DS-R1 speed estimates?
These are estimates with real error bars. The fastest result here, the range beneath each figure, could reasonably land anywhere in its published range depending on which runtime you use.
Is MAI-DS-R1 open source?
Its weights are published, so MAI-DS-R1 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 MAI-DS-R1 have?
MAI-DS-R1 has 671B parameters. 671B MoE. 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 MAI-DS-R1?
MAI-DS-R1 was published by Microsoft, based in United States of America, categorised as industry.
When was MAI-DS-R1 released?
MAI-DS-R1 was published in April 2025.
What is MAI-DS-R1 used for?
MAI-DS-R1 works in Language, and is recorded as handling language modeling/generation, Question answering, Quantitative reasoning, Code generation. 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 MAI-DS-R1?
Its weights are published under the microsoft organisation on Hugging Face. We do not host model files — this site calculates what hardware is needed to run them.
Can I run MAI-DS-R1 if it does not fit in my GPU?
Partly. Layers that do not fit sit in system memory and run at a fraction of the speed, so a mostly-offloaded MAI-DS-R1 is rarely worth using — the nearest miss we calculate is short by 147.5 GB. Every figure here assumes the whole model is on the card.
Would two GPUs run MAI-DS-R1 faster?
A second card roughly doubles the memory available but not the generation rate. With 0 cards already able to run MAI-DS-R1 alone, the case for pairing is weak.
Why does the quantisation differ between cards for MAI-DS-R1?
Each card is shown running the least-compressed copy it can hold, and MAI-DS-R1 appears at 1 different compression levels across the cards that fit it. Bigger cards get the more accurate version.
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.
