Not yet benchmarked
Claims drawn from cited facts, not live model generation.
Developed by swiss-ai, this model was released in 2025 with 8.05 billion parameters, placing it at the compact-to-mid-size scale. That scale implies relatively efficient deployment and lower cost, though with less headroom than frontier-scale models.
4 cited facts
This model is not yet benchmarked, so it holds no current top scores.
2 cited facts
This model holds the top score on none of the tracked benchmarks, so it shows no category-leading result yet. The average gap to state-of-the-art scores is unknown, so no frontier-position band can be derived from that measure.
