Chinchilla (language model)
Chinchilla is a family of
It claimed to outperform
Chinchilla has an average accuracy of 67.5% on the
Chinchilla contributes to developing an effective training paradigm for large autoregressive language models with limited compute resources. The Chinchilla team recommends that the number of training tokens is twice for every model size doubling, meaning that using larger, higher-quality training datasets can lead to better results on downstream tasks.[5][6]
Architecture
Both the Gopher family and Chinchilla family are families of
In particular, they are essentially the same as
The Gopher family contains six models of increasing size, from 44 million parameters to 280 billion parameters. They refer to the largest one as "Gopher" by default. Similar naming conventions apply for the Chinchilla family.
Table 1 of [2] shows the entire Gopher family:
Parameter count | Layers | Number of heads | Key/Value size | Internal dimension | Max learning rate | Batch size |
---|---|---|---|---|---|---|
44M | 8 | 16 | 32 | 512 | 6 × 10−4 | 0.25M |
117M | 12 | 12 | 64 | 768 | 6 × 10−4 | 0.25M |
417M | 12 | 12 | 128 | 1,536 | 2 × 10−4 | 0.25M |
1.4B | 24 | 16 | 128 | 2,048 | 2 × 10−4 | 0.25M |
7.1B | 32 | 32 | 128 | 4,096 | 1.2 × 10−4 | 2M |
Gopher 280B | 80 | 128 | 128 | 16,384 | 4 × 10−5 | 3M → 6M |
Table 4 of [1] compares the 70-billion-parameter Chinchilla with Gopher 280B.
Parameter count | Layers | Number of heads | Key/Value size | Internal dimension | Max learning rate | Batch size |
---|---|---|---|---|---|---|
Gopher 280B | 80 | 128 | 128 | 16,384 | 4 × 10−5 | 3M → 6M |
Chinchilla 70B | 80 | 64 | 128 | 8,192 | 1 × 10−4 | 1.5M → 3M |
