NT 2.5B, efficient inference implementation (Saadat and Fellay 2026)
NT 2.5B forward pass run with FlashAttention exact attention, padding-free sequence packing through the variable-length FlashAttention interface, and token-budget batching; attention stays exact and weights are unchanged.

Evidence
Source checking verifies the cited claim or transcription. It does not establish independent reproduction.
Evidence table
Inspect claims, sources and review details
Trace each statement to its source and review. A context-only reference supports the record generally; it does not verify an individual field. Source checking does not reproduce an experiment.
One row per statement and cited source. Multiple citations are not independent evaluations. Shared locators are labelled explicitly.

- provenance note
- Implementation and measurements by Saadat and Fellay (EPFL), who did not develop the model. Checkpoint identity is not stated, so the configuration stays at family level.
- missing metadata
- checkpoint: reason: unreported; note: The paper names the family and parameter count only. No Hugging Face repository, revision or pretraining dataset is given (several GENA-LM and Nucleotide Transformer checkpoints share these sizes).; version: reason: unreported; note: No code release or software versions are given in the PDF
- review
- reviewer: claude; reviewer note: Claude review agent; no human review claimed. Independent Claude (Opus 5.5) review agent, separate from the extraction agent that built this batch.
