✓ Good for

  • technical reasoning on science topics (#32 of 198 on GPQA Diamond)
  • calculation and problems with an exact answer (#37 of 186 on OTIS Mock AIME)

✕ Not the best for

  • answering short facts with little invention (#53 of 87 on SimpleQA Verified)
  • fixing bugs in real code (#17 of 32 on SWE-bench Verified)
  • when the input budget sits at the top of the table (input price in the highest 25% on OpenRouter)

This block follows a rule of this section, using source data: if the model is in the top 25% of the metric, the item goes under "Good for"; if it is in the bottom half, it goes under "Not the best for". The middle band appears in neither. Price and context use OpenRouter; scores use Epoch AI or OpenRouter Benchmarks, in the latest version we checked.
