Estimate from the version's published specs, benchmarks and reviews, 0-5; scores are only comparable within one criteria year. Scored as launched; family pin, flagship Llama 3.1 405B named (8B and 70B ship alongside; 23 Jul 2024). Reasoning/coding null: no AA Intelligence Index or Terminal-Bench figure at launch; Meta's headline benchmarks (e.g. MMLU, GPQA) are not comparable to the anchors. Context 128k (Meta blog) -> 1. Price: Meta published no list price; hosted launch-week price for 405B was Together Turbo $5.00 per 1M in/out (Wayback 30 Jul 2024; Fireworks listed $3.00) -> 3.5. Speed null. Modalities 1: text only (TechCrunch). Reviews are launch coverage and commentary relaying Meta's benchmarks (Simon Willison, Interconnects, The Register, Tom's Guide); no hands-on test of the 405B opened.[1]
it really is benchmarking in that GPT-4+ class, competitive with both GPT-4o and Claude 3.5 Sonnet.
The 405 billion parameter model is directly in the ballpark of Anthropic's Claude 3 and OpenAI's GPT-4o.
The result is a model that, at least according to Meta's benchmarks, is ahead of larger, more proprietary systems from OpenAI and Anthropic on a variety of benchmarks.
quickly gained a reputation as one of the most powerful and useful models available

A primeira entrada é sempre a fonte do pin. A confiança geral é uma média ponderada de quanto cada referência sustenta os horários de início e fim usados acima; uma referência conta metade a cada 180 dias a mais em relação à mais recente.
A publicação da Meta 'Introducing Llama 3.1: Our most capable models to date' é datada de 23 de julho de 2024 e diz que os modelos estavam disponíveis para download naquele dia; a carta aberta de Zuckerberg e o TechCrunch[6] têm a mesma data.
Meta's[1] model card: 15T+ pretraining tokens, 39.3M H100-80GB GPU hours (30.84M for the 405B), December 2023 knowledge cutoff, Llama 3.1 Community License and the instruction-tuned benchmark table.
Dates the line: Llama 3 on 18 April 2024 with 8B and 70B, Llama 3.1 on 23 July 2024 with 8B, 70B and 405B, Llama 4 in April 2025.[1]
The technical paper: dense 405B Transformer with a context window of up to 128K tokens, performance comparable to GPT-4 on many tasks, plus Llama Guard 3 and the not-yet-released multimodal work.[1]
Mark Zuckerberg's open letter published with the release: 405B is the first frontier-level open source model, inference at roughly 50% of the cost of closed models like GPT-4o, and the partners (Amazon, Databricks, NVIDIA, Groq, Dell, Scale.AI).[1]
Falta algo ou há um erro? Diga com suas palavras: um link que sustente este pin, uma data de início ou fim diferente e por quê, ou um fato que falta ou está errado. A IA confere isso com as fontes do pin, procura outras melhores e adiciona qualquer página que dê razão a você. As fontes do próprio pin continuam contando mais. Uma imagem que mostra outra coisa, ou mostra mal, também é analisada e rebaixada ou substituída.
