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.

What it does
The problem areas the model was built for. A model can carry several of each.
- Domain
- Language, Vision, Multimodal
- Task
- Language modeling/generation, Question answering, Code generation, Quantitative reasoning, Translation, Instruction interpretation, Visual question answering
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.
- Training data
- tokens
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
- 3.4 × 10²⁵ FLOP
- Plausible range
- 1 × 10²⁵ – 1 × 10²⁶ FLOP

What the numbers mean
About this model
Claude 3.7 Sonnet was published by Anthropic, in the country recorded as United States of America, during February 2025. It comes out of an organisation categorised as industry.
It works in the domain of Language, Vision, Multimodal, and is recorded as performing the task of language modeling/generation, Question answering, Code generation, Quantitative reasoning, Translation, Instruction interpretation, Visual question answering.
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
Training and provenance
The training run consumed about 3.4 × 10²⁵ FLOP. That figure measures what producing the model cost, and has no bearing on how fast it answers.
The reason it appears in this catalogue at all: training cost.
Answers
Claude 3.7 Sonnet — common questions
Claude 3.7 Sonnet— what is it used for?
It works in the domain of Language, Vision, Multimodal, and is recorded as handling the task of language modeling/generation, Question answering, Code generation, Quantitative reasoning, Translation, Instruction interpretation, Visual question answering. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.
Claude 3.7 Sonnet— how much compute was used to train it?
Training consumed around 3.4 × 10²⁵ 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.
Claude 3.7 Sonnet— what GPU do I need to run it?
None. This 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.
Claude 3.7 Sonnet— is it open source?
No. Its weights have not been published, so it exists only as a service controlled by its owner.
Claude 3.7 Sonnet— how many parameters does it have?
No parameter count has been published for it, which is why no memory or speed figure appears on this page.
Claude 3.7 Sonnet— who created it?
It was published by Anthropic, based in United States of America, an organisation categorised as industry.
Claude 3.7 Sonnet— when was it released?
It was published in February 2025.
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.
