The first frontier-scale open-weight language model
Llama 3.1 405B is Meta's 405-billion-parameter dense open-weight model, released in July 2024. It was the first openly available model to reach frontier-level performance on reasoning, coding, and multilingual tasks, with a 128K-token context window and native tool-use support.
Why: Llama 3.1 405B remains a landmark open release: it proved open weights could compete with proprietary frontier models and still serves as a high-quality baseline for research and synthetic-data generation.
