Fusion in Encoder
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.

"The experiments were run on 8x80GB Nvidia A100s with 800GB RAM and 4x32-core CPUs, and each experiment took around 1 day for NQ and 2 days for TriviaQA with large models. Inference was run on the same system, and took 2 minutes." 2 days * 24 * 3600 * 8 * 312 teraflop/s * 0.3 utilization = 1.3e20

"The source code is based on the original implementation of FiD (Izacard and Grave, 2021b), which can be found at their Github. The modeling for the fused Electra model was implemented using HuggingFace (Wolf et al., 2020) by modifying the ElectraModel.

What the numbers mean
About this model
Fusion in Encoder was published by Samsung, in Korea (Republic of), in November 2022. industry is the category the publisher falls under.
It works in Language, and is recorded as doing question answering, Language modeling/generation.
Its weights were never published, so it can only be reached through its provider. No graphics card changes that.
What went into building it
Producing it required around 1.3 × 10²⁰ FLOP of arithmetic, on NVIDIA A100 SXM4 80 GB, which is a statement about the training budget rather than about inference.
Around 960,000 tokens went into training it.
It is tracked in the underlying dataset for one reason in particular: sOTA improvement.
Answers
Fusion in Encoder — common questions
How much compute was used to train Fusion in Encoder?
Around 1.3 × 10²⁰ FLOP, on NVIDIA A100 SXM4 80 GB. 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.
What GPU do I need to run Fusion in Encoder?
None. Fusion in Encoder 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.
Is Fusion in Encoder open source?
No. Fusion in Encoder has not had its weights published, so it exists only as a service controlled by its owner.
How many parameters does Fusion in Encoder have?
Fusion in Encoder has 330M parameters. 330M. 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 Fusion in Encoder?
Fusion in Encoder was published by Samsung, based in Korea (Republic of), categorised as industry.
When was Fusion in Encoder released?
Fusion in Encoder was published in November 2022. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
What is Fusion in Encoder used for?
Fusion in Encoder works in Language, and is recorded as handling question answering, Language modeling/generation. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.
