  • To actually read how they did it, here is there model page: https://huggingface.co/gradientai/Llama-3-8B-Instruct-Gradient-1048k

    Approach:

    • meta-llama/Meta-Llama-3-8B-Instruct as the base
    • NTK-aware interpolation [1] to initialize an optimal schedule for RoPE theta, followed by empirical RoPE theta optimization
    • Progressive training on increasing context lengths, similar to Large World Model [2] (See details below)

    Infra

    We build on top of the EasyContext Blockwise RingAttention library [3] to scalably and efficiently train on contexts up to 1048k tokens on Crusoe Energy high performance L40S cluster.

    Notably, we layered parallelism on top of Ring Attention with a custom network topology to better leverage large GPU clusters in the face of network bottlenecks from passing many KV blocks between devices. This gave us a 33x speedup in model training (compare 524k and 1048k to 65k and 262k in the table below).

    Data

    For training data, we generate long contexts by augmenting SlimPajama. We also fine-tune on a chat dataset based on UltraChat [4], following a similar recipe for data augmentation to [2].






  • One of the most enlightening moments for me recently has been when a sociology researcher attempted an experiment on youtube to prove that we can organize without hierarchy. His main point was not what was interesting to me.

    His experiment was actually flawed in a major way: he proposed a task to a group of 100 that was doable even by a single person. In such a case, organization is easy. But what I found interesting is that even in such a setting hierarchies emerged: people took some organizational power and others followed. Even if that was clearly unnecessary. And the crowd following his channel are probably less authoritarian than average.

    It was a revelation to me: to have flat structures, you not only need to make it possible to organize without hierarchy, but you also need a process to constantly weed out emerging hierarchies. Another theory is that you should rather explicit some lesser-evil hierarchies to prevent the emergence of others, in the same way you may let one weed grow to prevent the emergence of other less desirable ones.

    I still don’t have a theory or a praxis that goes with it, but that has been good food for thought.







  • That’s according to a peer-reviewed study funded by the Ford Motor Company, a company that makes most of its profits from gas-powered vehicles.

    If you want to see if a tech is part of a renewable future, it is direct emissions that should be counted. EVs are at zero. They don’t emit CO2 when running, when being produced or when being disposed of. They use electricity and transport, two things that we can provide without emitting CO2. They are a piece of the puzzle of a sustainable society, something thermal cars will never be, and something these graphs hide.

    Of course we will be better off without cars and trucks, but the road towards them being totally gone is long, and it is time we don’t have.
