# tFINE-850m-24x24-1024ctx


Pretrained T5 model with [nanoT5](https://github.com/pszemraj/nanoT5/tree/fineweb-edu-test):

- ~850m parameters, 24 layers in encoder, 24 layers in decoder
- sentencepiece tokenizer with 48k vocab & byte-pair fallback
  - handles whitespaces etc correctly (_unlike original T5 tokenizer_)
- 1024 ctx during pretrain
- `relative_attention_num_buckets` increased to 48 from 32 for context length upscaling
