Hello there!! 👋👋
Meet Grok-1, a cutting-edge language model from X, formerly Twitter and owned by Elon Musk, which advances AI. 🚀 He has promised to open source Grok-1, and it was dropped for public use yesterday.
Here are the highlights of this model: I explained each one separately below what each item means.
🚀 314B params MoE
💡 8 experts (2 active) - 86B active parameters.
🥞 64 layers
🔍 48 attention heads for queries
🔑 8 attention heads for keys/values
💾 Embeddings size: 6,144
🔄 Rotary embeddings (RoPE)
📝 SentencePiece tokenizer: 131,072 tokens
🚀 Supports activation sharding and 8-bit quantization
📊 Max seq length (context): 8,192 tokens
🛠 Base model.
📜 Apache 2.0 Licensed!
A Big Brain with Billions of Connections 🧠
Imagine Grok-1 as a massive brain with 314 billion tiny switches called "parameters." These parameters help Grok-1 learn and understand patterns in language. But here's the cool part: Grok-1 uses a special technique called "Mixture-of-Experts" (MoE) to make the most of its brain power. It's like having 8 expert teams (2 active at a time) working together, using 86 billion active switches to process information efficiently. 💡
Layers Upon Layers of Understanding 🥞
To make sense of complex language, Grok-1 has 64 layers of processing. Think of it as a 64-story building, where each floor helps refine and improve the understanding of the text. On each floor, Grok-1 has special attention units – 48 for asking questions (queries) and 8 for finding answers (keys/values). These attention units help Grok-1 focus on the most important parts of the text. 🔍🔑
Storing and Representing Words 💾
Grok-1 uses "embeddings" to store and represent words in a way that the AI can understand. Imagine a big closet with 6,144 shelves, where each word has its own unique spot. This helps Grok-1 quickly find and use the right words when needed. To make the word storage even more efficient, Grok-1 uses a special technique called "Rotary Positional Embeddings" (RoPE). It's like having a rotating system in the closet to easily access words based on their position in a sentence. 🔄
Breaking Down Text into Pieces 📝
To process text, Grok-1 uses a tool called the "SentencePiece" tokenizer. It's like having a special machine that breaks down sentences into 131,072 smaller pieces called tokens. This helps Grok-1 understand and work with text more efficiently.
Efficient Processing and Memory Usage 🚀
When Grok-1 is working on a task, it uses smart techniques like "activation sharding" and "8-bit quantization" to process information quickly and use memory efficiently. It's like having a well-organized workstation that saves time and space.
Understanding Long Text Passages 📜
Grok-1 can understand and work with long pieces of text, up to 8,192 tokens in length. That's like reading a long article or story and still being able to keep track of the main ideas and details. 📊
A Model for Everyone 🌍
The best part about Grok-1 is that it's open-source and licensed under Apache 2.0. This means that anyone can use, study, and build upon this incredible AI model. It's like having a powerful tool that everyone can benefit from and contribute to. 📜
Grok-1 is a remarkable AI language model that pushes the boundaries of what's possible. With its billions of connections, layered understanding, efficient processing, and open-source nature, Grok-1 is set to revolutionize how we interact with and benefit from AI. Get ready for a future where AI models like Grok-1 make our lives easier, more productive, and more fun! 🎉
Here is the link for code in github. Please do check the notes below on the requirements and limitations.
Note:
Due to the large size of the model (314B parameters), a machine with enough GPU memory is required to test the model with the example code.
The implementation of the MoE layer in this repository is not efficient. The implementation was chosen to avoid the need for custom kernels to validate the correctness of the model.
