Code Llama

Code Llama, Meta's open-source coding model built on Llama 2, is a strong contender in the AI coding space. Available in 7B, 13B, 34B, and 70B parameter variants, it offers impressive flexibility for different hardware constraints and use cases. The model excels at code generation, completion, and debugging across popular languages like Python, C++, and Java, with a specialized Python-tuned variant for data science workflows. Being fully open-source and free is a massive advantage"developers can self-host, fine-tune, and integrate it without licensing costs or API fees. It supports up to 100K token context windows in certain configurations, which is excellent for large codebases. However, it falls short of GPT-4 and Claude in complex reasoning tasks and multi-step problem solving. The lack of a polished hosted API from Meta means setup requires more technical effort compared to commercial alternatives. Community support through Hugging Face is robust, and the model runs well with tools like Ollama and vLLM. For teams prioritizing data privacy and cost efficiency, Code Llama is an excellent choice.
