Preliminary experiments ently large language models are able to ”I’m not the cleverest man in the world, but like they say in French: Je ne suis pas un imbecile [I’m not a fool]. In a now-deleted post from Aug. 16, Soheil Eid, Tory candidate in the riding of Joliette, wrote in French: ”Mentez mentez, il en restera toujours quelque chose,” which translates as, ”Lie lie and something will always remain.” “I hate the word ‘perfume,”’ Burr says. ‘It’s somewhat better in French: ‘parfum.’ If listened carefully at 29:55, a conversation can be heard between two guys in French: “-Comment on fait pour aller de l’autre cot´ e? -Quel autre cot´ e?”, which means “- How do you get to the other side? - What side?”. If this sounds like a bit of a stretch, consider this ques- tion in French: As-tu aller au cin´ ema?, or Did you go to the movies?, which literally translates as Have-you to go to movies/theater? 例: 英語 ⇒ フランス語 以下のようなテキストがWebには たくさんある → ここから ⾔語モデルを学習 ※ GPT-2の論⽂から引⽤

All models were trained for a total of 300 billion tokens. 2.1 Model and Architectures We use the same model and architecture as GPT-2 [RWC+19], including the modified initialization, pre-normalization, and reversible tokenization described therein, with the exception that we use alternating dense and locally banded sparse attention patterns in the layers of the transformer, similar to the Sparse Transformer [CGRS19]. To study the dependence of ML performance on model size, we train 8 different sizes of model, ranging over three orders of magnitude from 125 million parameters to 175 billion parameters, with the last being the model we call GPT-3. Previous work [KMH+20] suggests that with enough training data, scaling of validation loss should be approximately a smooth power law as a 1GPUだと数⼗〜数百年 (そもそもモデルがGPU メモリに乗らないので 不可能) GPT-2 ≒

As a consequence, although G 10x larger than RoBERTa-Large (355M params), both models took roughly 50 petaflop/s-days of e-training. Methodology for these calculations can be found in Appendix D.
