Llama models are also still best in class for specific tasks that require local data processing. They also maintain positions in the top 25 of the lmarena leaderboard (for what that's worth these days with suspected gaming of the platform), which places them in competition with some of the best models in the world.
But, going back to my first point, Llama set the stage for almost all open weights models after. They spent millions on training runs whose artifacts will never see the light of day, testing theories that are too expensive for smaller players to contemplate exploring.
Pegging Llama as mediocre, or a waste of money (as implied elsewhere), feels incredibly myopic.
