  #### Summary
86
 
87
- - **Mean:** blink-8M has the highest mean (55.35), just ahead of lattice (55.24) and about 1 point ahead of bekko (54.38).
88
  - **Retrieval-type tasks:** blink-8M is best on retrieval, reranking and pair classification. On retrieval it scores 38.86, against 38.01 for lattice and 31.22 for potion-base-8M. Note that this task has significant overlap with BEIR, see below.
89
  - **Other tasks:** the potion-base models are best on classification (70.48 and 70.41) and potion-base-8M on summarization (25.14), with blink-8M at 67.88 and 22.48. Bekko is best on STS and lattice on clustering.
90
  - **Against potion-base-8M:** at roughly the same size, blink-8M is 2.05 points higher on the mean and 7.64 points higher on retrieval, but 2.53 points lower on classification.
