  "account": "MoE, or Mixture of Experts, is a technique used in AI models that involves a large number of smaller networks working together to process information. However, not all experts are used for every input; instead, a router determines which experts should handle the current task. This approach allows for sparse activation, meaning only a subset of the experts is active at any given time.\n\nWhen considering the size of an MoE model, it's important to distinguish between total parameters and active parameters. Total parameters refer to the overall number of weights in the model, while active parameters are the weights that are actually being used for a specific token. For instance, a model with 8 experts, each containing 7 billion parameters, would have a total of 56 billion parameters. But, if only 2 experts are active for a particular token, the actual computational load would be significantly smaller.\n\nNow, let's talk about Edge Computing. This concept focuses on where computation takes place. Edge computing moves data processing closer to the source of the data or the user, instead of relying on centralized cloud servers. This can lead to faster response times and reduced bandwidth usage.\n\nEdge0 is an example that demonstrates how a large AI model can be run on a device like an iPhone with limited memory. The key here is that the model doesn't need to be entirely loaded into memory at once. Instead, only the necessary experts and their weights are loaded into RAM when needed, thanks to the router's decision-making process.\n\nIt's crucial to understand that MoE and Edge Computing are distinct concepts. MoE is about the architecture of the AI model, while Edge Computing is about where the computation occurs. An MoE model can run in the cloud, on a phone, or on any other edge device. Edge computing doesn't necessarily require an MoE model, as any AI model can be implemented on edge devices, depending on the specific requirements of the application.",
  "summary": "Recently, I came across an X demo of a 35B language model running on an iPhone using only 1–2.5 GB of peak memory. That sounds strange at first. A 35B model sounds like something that should need a lot of RAM and a powerful GPU. The project behind the demo, Edge0 , uses a technique called Mixture of Experts (MoE) to make this possible. This also made me realise that two terms can easily get mixed…",
