GLaM 8B/64E (MoE) is a closed-weights language model from Google, released December 2021. Its published size is 143B parameters (9.8B active per token). Licence: proprietary.

Catalogue identity notes

Google's GLaM 8B/64E mixture-of-experts model (Du et al., arXiv:2112.06905, Table 4: 143B total / 9.8B activated parameters), trained on the GLaM dataset. Research size from the same paper. Never released. Not the same checkpoint as LaMDA-PT even where sizes match. Comparison-only.

$ how the score was worked out · GLaM: Efficient Scaling of La… 99%

Each result implies a score on its own, after adjusting for how hard its test is and who ran it. The score is their weighted average, with a small pull toward the middle for thinly tested models. Each test's weight is its counts column above; here it's added up by who ran the tests. How it works
