The Llama family timeline: LLaMA (Feb 2023) → LLaMA-2 (Jul 2023) → Llama 3 (Apr 2024) → Llama 3.1 (Jul 2024) → Llama 3.2 (Sep 2024) → Llama 4 (Apr 2025).

Summary

This pins down the release dates and order of Meta's six Llama model generations, from the original 2023 launch through the April 2025 release. It matters because any claim about a Llama model's capabilities, training cutoff, or position in the family can be checked against this known cadence to see whether it is plausible or contradicts the established history.
