05a051dbe9 fix tokenization bug, there should be no space before first letter. sigh 2025-10-24 15:06:06 +00:00

8892470f29 add the SpellingBee task so that nanochat can count r in strawberry etc. along the way we had to add a bunch of new functionality, e.g. extend the calculator to support the count function of python. possibly the current TaskMixture uses way too many synthetic examples of SpellingBee because the eval gives us exactly 100% performance on spelling. We can tune this later to reclaim some wall clock time here I think 2025-10-24 14:02:48 +00:00
