Technical metadata and extraction receipts
Stable ID: catalog-model-evo-2
- areas
- dna-genomes; microbes-communities
- method types
- foundation model
- entity level
- family
- version
- 7B
- reported name
- Evo 2
- access
- Public checkpoints; official local inference needs CUDA hardware and substantial memory.
- method type
- foundation model
- historical missing metadata
- checkpoint revision: not_yet_extracted; training data: not_yet_extracted; licence: not_yet_extracted
- metadata review scope
- historical_missing_metadata preserves the original discovery state. Current descriptive evidence and missingness are recorded in profile.facts; numerical-result review is separate.
- entity classification
- review date: 2026-09-17; rationale: The cited profile describes a named learned biological predictor or representation model/family. Preserve this identity separately from task-specific fitting, individual checkpoints, pipelines and hosted access.; source ids: evidence-official-a248990b44d481814f47; evidence-official-849b751ed4bf88622749; evidence-official-b8df803e8f55324a4eb5; evidence-official-8717ffb993cc8f7eddec; source locator: Evo 2 paper: architecture, training, and data, Figure 1 and Discussion; official checkpoints table and evo2_7b licence metadata; ambiguities: None recorded
