Open weights LINE Corporation,Tohoku University June 2022

No estimate

No hardware requirements for this model

This model's weights are open, but no parameter count has been published for it. Every memory and speed figure starts from that number, so we would rather show nothing than a fabricated estimate.

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
103,000,000 tokens

"We used WikiText-103 (Merity et al., 2017), which consists of a large number of tokens. The training, validation, and test sets contain 103M, 0.2M, and 0.2M tokens, respectively" Table 6 updates: 50K tokens/GPU: 1024 GPUs (Table 7): 192 50000*1024*192/103000000 = 95 epochs

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
2.8 × 10¹⁹ FLOP

192*7 GPU (P100) hours per Table 6 19 TFLOP/s 19 trillion * 192 * 7 * 3600 * 0.3 = 2.76e19 6 FLOP / parameter / token * 247000000 parameters [not sure how it was estimated] * 50000 steps * 1024 tokens / GPU * 192 GPUs = 1.4568653e+19 FLOP

What the numbers mean

Background

B2T connection (16L) was published by LINE Corporation,Tohoku University, in the country recorded as Japan, during June 2022. The category the publisher falls under is industry,Academia.

It works in the domain of Language, and is recorded as performing the task of language modeling/generation, Question answering.

The weights are published, so it can be downloaded and run on your own hardware indefinitely, offline, with no account attached.

Training and provenance

The training run consumed about 2.8 × 10¹⁹ FLOP, on hardware recorded as NVIDIA P100. That figure measures what producing the model cost, and has no bearing on how fast it answers.

It was trained on a corpus of about 103,000,000 tokens of text.

Answers

B2T connection (16L) — common questions

01

B2T connection (16L)— where can I download it?

The weights are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.

02

B2T connection (16L)— how much compute was used to train it?

Training consumed around 2.8 × 10¹⁹ FLOP, on hardware recorded as NVIDIA P100. 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.

03

B2T connection (16L)— what GPU do I need to run it?

We cannot say. It has open weights, but no parameter count has been published for it, and every memory and speed calculation starts from that number. We would rather show nothing than a fabricated estimate.

04

B2T connection (16L)— 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.

05

B2T connection (16L)— 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.

06

B2T connection (16L)— who created it?

It was published by LINE Corporation,Tohoku University, based in Japan, an organisation categorised as industry,Academia.

07

B2T connection (16L)— when was it released?

It was published in June 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.

08

B2T connection (16L)— what is it used for?

It works in the domain of Language, and is recorded as handling the task of language modeling/generation, Question answering. 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.
