The upcoming Llama-3-400B+ will mark the watershed moment that the community gains open-weight access to a GPT-4-class model. It will change the calculus for many research efforts and grassroot startups. I pulled the numbers on Claude 3 Opus, GPT-4-2024-04-09, and Gemini.

Very nice analysis on long context vs RAG. I believe the way of future will be βsoftβ methods that interpolate between pure retrieval and pure long context. Some form of spreading neural activations across a giant unstructured database.
Over the last two days after my claim "long context will replace RAG", I have received quite a few criticisms (thanks and really appreciated!) and many of them stand a reasonable point. Here I have gathered the major counterargument, and try to address then one-by-one (feels like

FlashAttention-2 was released today, which is 5-9X faster than vanilla attention and 2X faster than FlashAttention-v1. Given that many of the top open-source LLMs leverage FlashAttention, this is an important advancement that can make existing models much more efficient during
Announcing FlashAttention-2! We released FlashAttention a year ago, making attn 2-4 faster and is now widely used in most LLM libraries. Recently Iβve been working on the next version: 2x faster than v1, 5-9x vs standard attn, reaching 225 TFLOPs/s training speed on A100. 1/

The license of the Falcon 40B model has just been changed toβ¦ Apache-2 which means that this model is now free for any usage including commercial use (and same for the 7B) π
LLaMa is dethroned π A brand new LLM is topping the Open Leaderboard: Falcon 40B π© *interesting* specs: - tuned for efficient inference - licence similar to Unity allowing commercial use - strong performances - high-quality dataset also released Check the authors' thread π
