Strong disagree.

Llama 4's release in 2025 is (deservedly) panned, but Llama 3.1 405b does not deserve that slander.

Do not compare 2024 models to the current cutting edge. At the time, Llama 3.1 405b was the very first open source (open weights) model to come close to the closed source cutting edge. It was very very close in performance to GPT-4o and Claude 3.5 Sonnet.

In essence, it was Deepseek R1 before Deepseek R1.
