Claims drawn from cited facts, not live model generation.
This model comes from Meta AI and was released in 2026, placing it in a distinctly recent vintage rather than a legacy lineage. Because this model's origin and release year are the only scale-relevant facts available, its recency is the whole story here: a 2026 build from Meta AI speaks to an actively maintained line rather than a frozen, older generation.
4 cited facts
This model is scored on six tracked benchmarks. Of those, it currently holds the top score on one. Its record can be taken at face value: the results have been independently reproduced by outside evaluation rather than left as vendor-claimed figures.
