For years since the GPT-2 paper, emergent in-context learning (ICL) from 'next-token' training has been treated as something deeply tied to ๐ก๐ฎ๐ฆ๐๐ง ๐ฅ๐๐ง๐ ๐ฎ๐๐ ๐. But โฆ is it?
Thrilled to share our latest result: ๐๐ฒ๐ป๐ผ๐บ๐ถ๐ฐ๐งฌ ๐บ๐ผ๐ฑ๐ฒ๐น๐ ๐๐ฟ๐ฎ๐ถ๐ป๐ฒ๐ฑ ๐ค๐ฃ๐ก๐ฎ ๐ผ๐ป '๐ป๐ฒ๐ ๐-๐ป๐๐ฐ๐น๐ฒ๐ผ๐๐ถ๐ฑ๐ฒ ๐ฝ๐ฟ๐ฒ๐ฑ๐ถ๐ฐ๐๐ถ๐ผ๐ป' ๐ฒ๐ ๐ต๐ถ๐ฏ๐ถ๐ ๐๐๐!
What's remarkable is that their overall pattern closely mirrors LLMs:
โ similar few-shot pattern induction
โ similar log-linear gains with more shots
โ similar improvement with model scale
... all learned purely from DNA (nucleotide) sequences.

We built a suite of symbolic bitstring-reasoning tasks and encoded them two ways: (1) genomic alphabet (A/T/C/G) and (2) linguistic alphabet (digits). This lets us compare Evo2 (genomic) vs Qwen3 (language) under matched few-shot prompts.

Huge thanks to @N8Programs for leading the work, and to collaborators @anqi_liu33 @aamixsh @mrevsine @mike_schatz.
We're extremely thankful to the Evo2 team ( @BrianHie @pdhsu @garykbrixi @mgdurrant @MichaelPoli6 etc.). Not only these models help advance biomed research, now we see that they can help AI community better understand the fundamentals of pre-training.
