Code Llama 7B, developed by Meta, is a specialized language model designed for code generation and completion tasks. With 7 billion parameters, it offers a balance between performance and resource requirements, making it suitable for developers and teams looking to enhance their coding productivity without the need for high-end hardware. The model excels in generating syntactically correct and contextually relevant code snippets, which can significantly speed up development processes. Its context length of 16,384 tokens allows it to handle complex and lengthy codebases, ensuring that it can maintain context over extended sequences.
In its size class, Code Llama 7B punches well above its weight. It delivers comparable performance to larger models while requiring less computational power, making it an efficient choice for local deployment. This efficiency is particularly evident in its VRAM requirements, ranging from 4.3 to 7.2 GB, which means it can run smoothly on mid-range GPUs. Developers and small teams with limited resources will find this model especially useful, as it provides robust code generation capabilities without the need for expensive hardware upgrades. Realistically, any system with a decent GPU and at least 8 GB of RAM should be able to run Code Llama 7B effectively, making it a versatile tool for a wide range of coding environments.

Throughput is a sub-linear estimate: doubling users adds ~70 % of single-user TPS until ~8, then plateaus on memory bandwidth. MoE models scale concurrency much better because each user activates a different subset of experts.
