Claims drawn from cited facts, not live model generation.
Developed by Meta AI and released in 2026, this model represents Meta's continued investment in open AI research.
2 cited facts
This model is scored on four tracked benchmarks. It holds no current top score on any of them. The record is unverified: neither independently reproduced nor contradicted by outside evaluation, so treat the numbers as unconfirmed claims.
3 cited facts
Based on avg_sota_gap, this model trails the leader by 28.82 points on average, a wide gap that places it well behind the leaders rather than at the frontier. Its sota_leader_count is 0, meaning it holds the top score on none of the evaluated benchmarks, so it has no genuine category leadership.
