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.

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
250,000 molecules × 50 tokens/molecule = 12,500,000 tokens Total training datapoints = 12,500,000 tokens (1.25e7)
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
- 3.7 × 10¹⁹ FLOP
- How it was established
- Hardware
1. Hardware setup: 4x NVIDIA Tesla P100 GPUs (1.90×10¹³ FLOP/s per GPU) 2. Training duration: 14 days (directly provided) = 1,209,600 seconds 3. Utilization rate: 40% 4. Final calculation: 1.90×10¹³ FLOP/s/GPU × 4 GPUs × 1,209,600 seconds × 0.4 = 3.7×10¹⁹ FLOPs

What the numbers mean
What this model is
Mothra was published by Tokyo Institute of Technology, in the country recorded as Japan, during September 2024. The publishing organisation is categorised as academia.
It works in the domain of Biology, and is recorded as performing the task of drug discovery.
Its weights were never published, so it can only be reached through its provider. No graphics card changes that.
How it was trained
The training run consumed about 3.7 × 10¹⁹ FLOP. That figure measures what producing the model cost, and has no bearing on how fast it answers.
Answers
Mothra — common questions
Mothra— how much compute was used to train it?
Training consumed around 3.7 × 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.
Mothra— 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.
Mothra— is it open source?
The licensing was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.
Mothra— 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.
Mothra— who created it?
It was published by Tokyo Institute of Technology, based in Japan, an organisation categorised as academia.
Mothra— when was it released?
It was published in September 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.
Mothra— what is it used for?
It works in the domain of Biology, and is recorded as handling the task of drug discovery. 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.

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.
