Computed differences from catalog data
- The listed context windows are 512 tokens and 512 tokens; the larger is 1× the smaller.
- No shared benchmark labels are present in both catalog records.
- The first listed parameter quantities are 125M and 66M; the larger quantity is 1.89× the smaller. Total and active MoE parameters are not directly equivalent.
- A release-date gap cannot be calculated from the catalog values (Twitter RoBERTa Sentiment: 2021; DistilBERT SST-2: 2019).
Cost example: 1M input and 1M output tokens
A cost example for 1M input plus 1M output tokens cannot be calculated reliably because separate numeric input and output rates are not listed for both models.
