Omnii-1 genome model launched; AI-designed phage given to human patient for first time
On October 21, the exnx team released Omnii-1, a new multimodal genomic language model, along with a world-first announcement: an AI-generated bacteriophage designed by Omnii-1 has been administered to a human patient with an antibiotic-resistant infection for the first time under compassionate use. The team calls Omnii-1 the most powerful genomic language model to date and positions it as "a major step toward general biological intelligence."
Confirmed
- Omnii-1 unifies 28 biological modalities including DNA, RNA, proteins, and epigenomics, trained on trillions of biological data tokens
- An AI-generated phage designed by the model was used to treat a drug-resistant infection patient under compassionate use — a global first
- Related accounts (@exnx, @JosephJacks, etc.) announced the news on the same day
Unconfirmed
- Posts differ on who is behind the release: Michael Poli (Liquid AI), Exnex, RadicalNumerics, and EvolutionaryScale have all been named; the original posts (m4, m5) point to the exnx team, but the company affiliation awaits official clarification
- The patient's treatment outcome and clinical details were not disclosed; only the fact of administration is known
Why it matters
- This is the first time an AI-generated biological sequence has entered human therapy, marking a key milestone as generative models move from design to clinical application
- Phage therapy is seen as a potential answer to antibiotic resistance, and AI design could greatly accelerate the discovery and optimization of candidate phages
- Covering 28 biological modalities, the model — if its capabilities hold — pushes genomic modeling toward "general biological intelligence"
