Decode (AI)
The 'writing' phase in an LLM's process, where the model generates a response one token at a time. This phase is memory-bandwidth constrained and is Groq's architectural strength.

Summary
Decode (AI) refers to a critical phase of artificial intelligence processing, specifically during the inference stage of large language models (LLMs). While the 'Prefill' phase handles the initial ingestion and processing of input data, the 'Decode' phase is responsible for the sequential generation of output tokens. This technical distinction has become a cornerstone of AI infrastructure development, with companies like Groq specializing in dedicated inference chips designed to optimize the Decode phase for speed and cost-efficiency. The importance of this processing stage is highlighted by the $20 billion Groq-Nvidia deal, which seeks to balance Nvidia's dominance in GPU-based Prefill processing with Groq's specialized decoding hardware. Beyond technical infrastructure, the term is also used in educational and industry contexts, such as the 'AI Decoded' initiative by ITS America, to explain the practical applications and internal mechanics of machine learning to a broader audience.

words are first tokenized they turn into numbers is a position in a dictionary of all of the words that the model handles the tokens are then passed into an embedding layer and mapped into vectors which are highly dimensional space where each token occupies a unique location within that space these tokens of course represent the words and those words are related to each other those words that are related to each other are located close to each other in the embedding space and the distance [...] for a machine and to perform this type of task we'd need a much more complex network of neurons but in our simple example we can give each Neuron a score out of 10 relating to its input weight and if the input was over five then the neural neuron will fire so we have an activation on a tail because we can see one of those so that's quite confident it's an eight out of 10 and an activation on fur also that's less confident but still six out of 10 so still quite quite confident so these combined [...] and improve at a task over time and this is done by using mathematical and statistical techniques to identify patterns to optimize systems and to make predictions from data this can be applied to solving different classes of problems such as identifying objects in pictures recommending TV programs or even booking seats on a train another important definition is generative Ai and one that's arguably getting the most attention at the moment so this is a type of artificial intelligence capable of
