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.

Phi-4-Reasoning-plus is small enough at 14B parameters that hardware is rarely the obstacle — 306 of the cards we track can run it, including cards several years old.

At the low end, a P102-101 handles it — 10 GB, at IQ4_XS, for about 20.2 tokens per second.

The quickest result comes from a B200 at around 242 tokens per second — its 8,000 GB/s of bandwidth is what buys that.

About this model

Phi-4-Reasoning-plus 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, Quantitative reasoning, Question answering, Mathematical reasoning, Code generation.

It is derived from Phi-4-Reasoning rather than trained from scratch, which is the usual way a specialised model is produced.

Published weights mean the model runs on your machine rather than someone else's, which is what makes the hardware question below answerable at all. It is published under the microsoft organisation on Hugging Face.

How fast it runs, and why

The median result is around 20.4 tokens per second; 268 cards produce text faster than most people read it.

It is a dense model, so every parameter is read for every token produced. That makes speed track memory bandwidth almost exactly — a card with twice the bandwidth generates roughly twice as fast.

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.

Step by step

How to choose a GPU for Phi-4-Reasoning-plus

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

  1. 01

    Read the memory figure first

    The table lists every card that can hold Phi-4-Reasoning-plus — around 8.4 GB at IQ4_XS. That figure, not the card's headline performance, is what decides whether it runs.

  2. 02

    Decide how long your conversations run

    Longer conversations cost memory on top of what the weights need. Move the slider to your real working length before trusting any row for Phi-4-Reasoning-plus.

  3. 03

    Choose how far you will compress it

    Compression is what makes Phi-4-Reasoning-plus fit smaller cards, at some cost in accuracy — IQ4_XS on the smallest card that fits. A minimum quality removes the ones that go too far.

  4. 04

    Compare tokens per second, not specifications

    Ranking by tokens per second for Phi-4-Reasoning-plus follows memory bandwidth, not core counts, which is why the B200 tops it at 242 tok/s.

  5. 05

    Look at the headroom, not just the fit

    The fit column separates cards that just manage Phi-4-Reasoning-plus from those with room to spare. Buy for the second if the context might grow.

  6. 06

    Check the card from the other side

    Each card page repeats this sweep for every model we hold. It answers what else the hardware is good for, beyond Phi-4-Reasoning-plus.

Answers

Phi-4-Reasoning-plus — common questions

01

How fast is Phi-4-Reasoning-plus on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 242 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 268 of the cards that can run Phi-4-Reasoning-plus clear that.

02

How much VRAM does Phi-4-Reasoning-plus need?

About 8.4 GB at IQ4_XS 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.

03

Can I run Phi-4-Reasoning-plus on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q5_K_M, using about 10.8 GB and generating roughly 49.3 tokens per second — a tight fit.

04

Can I run Phi-4-Reasoning-plus on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q6_K, using about 12.4 GB and generating roughly 49.7 tokens per second — a tight fit.

05

Can I run Phi-4-Reasoning-plus on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 15.7 GB and generating roughly 40.5 tokens per second — a comfortable fit.

06

Is Phi-4-Reasoning-plus open source?

Its weights are published, so Phi-4-Reasoning-plus 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.

07

How many parameters does Phi-4-Reasoning-plus have?

Phi-4-Reasoning-plus has 14B parameters. 14B. 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.

08

Who created Phi-4-Reasoning-plus?

Phi-4-Reasoning-plus was published by Microsoft, based in United States of America, categorised as industry.

09

When was Phi-4-Reasoning-plus released?

Phi-4-Reasoning-plus was published in April 2025.

10

What is Phi-4-Reasoning-plus used for?

Phi-4-Reasoning-plus works in Language, and is recorded as handling language modeling/generation, Quantitative reasoning, Question answering, Mathematical reasoning, Code generation. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

11

Where can I download Phi-4-Reasoning-plus?

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.

12

Can I run Phi-4-Reasoning-plus 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 2.0 GB. Our figures for Phi-4-Reasoning-plus assume it is fully resident.

13

Would two GPUs run Phi-4-Reasoning-plus faster?

Capacity adds across cards; throughput does not. Since 306 of the cards we track already hold Phi-4-Reasoning-plus on their own, a second card is rarely the answer here.

14

Why does the quantisation differ between cards for Phi-4-Reasoning-plus?

Each card is shown running the least-compressed copy it can hold, and Phi-4-Reasoning-plus appears at 5 different compression levels across the cards that fit it. Bigger cards get the more accurate version.

15

How accurate are these Phi-4-Reasoning-plus speed estimates?

Every figure is derived from memory bandwidth and model size, not benchmarked. That is why each is published as a range such as 145–387 tok/s on the B200 rather than a single number.

16

What GPU do I need to run Phi-4-Reasoning-plus?

The smallest card in our catalogue that holds Phi-4-Reasoning-plus is the P102-101, with 10 GB of memory. It runs the model at IQ4_XS using about 8.4 GB, and produces roughly 20.2 tokens per second. 306 cards in total can run it.
