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.

Size
How large the model is and how much data it was trained on. Parameters are the figure that decides whether it fits on a given graphics card.
- Parameters
- 671B
- Training data
- 839,000,000,000 tokens
671B total, 37B active
From V3.1 training dataset information: "840B tokens continued pretraining for long context extension on top of V3" "The 32K extension phase has been increased 10-fold to 630B tokens, while the 128K extension phase has been extended by 3.3x to 209B tokens." 839B in total
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
- 3.6 × 10²⁴ FLOP
- How it was established
- Operation counting
- Fine-tuning compute
- 1.9 × 10²³ FLOP
This was based on V3 which was trained on 14.8T tokens for a total of 14.8T + 840B = 15.64T pretraining tokens. Adding the FLOPs from continued pretraining onto our estimate for V3, which is 3.4e24 FLOPs, we get 3.4e24 + 1.9e23 = 3.59e24
6 FLOP/parameter/token * 671000000000 parameters * 839000000000 tokens = 3.377814e+24 FLOP

What the numbers mean
The hardware side
DeepSeek-V3.1-Terminus reaches a parameter count of 671B. That is beyond what any single graphics card holds. Running it means either splitting it across several cards or renting hardware built for the job, and every card able to hold it alone is a datacentre part. The number that can: 0.
Where it came from
DeepSeek-V3.1-Terminus was published by DeepSeek, in the country recorded as China, during September 2025. It comes out of an organisation categorised as industry.
It works in the domain of Language, and is recorded as performing the task of language modeling/generation, Code generation, Quantitative reasoning, Question answering, Search, System control, Instruction interpretation.
It builds on DeepSeek-V3. Most models at this scale are adapted from an existing base rather than built from nothing.
The weights are published, so it can be downloaded and run on your own hardware indefinitely, offline, with no account attached. On Hugging Face it is published under the organisation deepseek-ai.
What went into building it
Producing it required arithmetic totalling around 3.6 × 10²⁴ FLOP. That figure measures what producing the model cost, and has no bearing on how fast it answers.
Training consumed a corpus of around 839,000,000,000 tokens of text.
Step by step
How to choose a GPU for DeepSeek-V3.1-Terminus
The table above has already assessed every card we hold specifications for against this model. Getting to your answer takes six steps.
-
01
Check what it needs before anything else
Start from what it actually needs, which is the requirement of DeepSeek-V3.1-Terminus. That figure, not the headline performance of a card, is what decides whether it runs.
-
02
Set the context length you will work at
Set the context to what you will actually use. The cache grows with the conversation, and it is the usual reason a card that seemed fine stops fitting DeepSeek-V3.1-Terminus.
-
03
Choose how far you will compress it
Each card runs the least-compressed copy it can hold. Setting a minimum quality drops the cards that only manage it by squeezing further than you would want, and holds the comparison at one level.
-
04
Sort by speed
Sort by speed to see how cards rank for DeepSeek-V3.1-Terminus. It will not match a gaming ordering, because generation is bound by memory bandwidth.
-
05
Check the fit verdict before buying
Tight means it loads and works with no room to raise the context later, in the case of DeepSeek-V3.1-Terminus. Comfortable means you can grow the context later. That difference matters more than a few tokens per second, so buy for comfortable if you expect to.
-
06
Check the card from the other side
Every card name links to its own page, which runs the same calculation across the whole model catalogue. A card is usually bought for more than one model, so it is worth a look before buying for DeepSeek-V3.1-Terminus.
Answers
DeepSeek-V3.1-Terminus — common questions
DeepSeek-V3.1-Terminus— how much compute was used to train it?
Training consumed around 3.6 × 10²⁴ 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.
DeepSeek-V3.1-Terminus— can I run it if it does not fit in my GPU?
Only by offloading, which is usually a false economy: the part held in system memory drags the whole thing down. The nearest miss we calculate falls short by 103.0 GB. Every figure here assumes the whole model is resident on the card.
DeepSeek-V3.1-Terminus— would two GPUs run it faster?
A second card roughly doubles the memory available but not the generation rate. The number already able to run it alone: 0. So a second card is rarely the answer here.
DeepSeek-V3.1-Terminus— why does the quantisation differ between cards?
A larger card holds a more accurate copy. The number of compression levels used across the cards that run it: 1. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.
DeepSeek-V3.1-Terminus— how accurate are these speed estimates?
Every figure is derived from memory bandwidth and model size, not benchmarked, which is why each is published as a range rather than a single number. One example: the range beneath each figure. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.
DeepSeek-V3.1-Terminus— is it open source?
Its weights are published, so it 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.
DeepSeek-V3.1-Terminus— how many parameters does it have?
It has a parameter count of 671B. 671B total, 37B active. 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.
DeepSeek-V3.1-Terminus— who created it?
It was published by DeepSeek, based in China, an organisation categorised as industry.
DeepSeek-V3.1-Terminus— when was it released?
It was published in September 2025.
DeepSeek-V3.1-Terminus— what is it used for?
It works in the domain of Language, and is recorded as handling the task of language modeling/generation, Code generation, Quantitative reasoning, Question answering, Search, System control, Instruction interpretation. 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.
DeepSeek-V3.1-Terminus— where can I download it?
Its weights are published on Hugging Face, under the organisation deepseek-ai. We do not host model files — this site calculates what hardware is needed to run them.
