Building on the solid foundation laid by its predecessor, Llama 2, CodeLlama 70b takes a step further by offering enhanced coding capabilities. It outshines its predecessors by handling more queries with an impressive accuracy of 53% on the HumanEval benchmark, surpassing GPT-3.5’s 48.1% and nearing the 67% mark achieved by GPT-4. This marked improvement in performance is a testament to the strides made in the field of AI-powered coding, demonstrating the potential of AI in transforming the coding landscape. The evolution from Llama 2 to CodeLlama 70b is a clear indication of the rapid advancements in AI technology, and the potential it holds for the future of coding.
Training and Fine-tuning Strategy
CodeLlama 70b was developed by fine-tuning Llama 2 using a higher sampling of code. It was trained on sequences of 16k tokens and shows improvements on inputs with up to 100k tokens. This allows it to efficiently process large blocks of code.
The model was trained on 1T tokens, which is a staggering amount of data. This extensive training has allowed CodeLlama 70b to reach state-of-the-art performance among open models on several code benchmarks.
The 7B and 13B base and instruct models have also been trained with fill-in-the-middle (FIM) capability, allowing them to insert code into existing code. This means they can support tasks like code completion right out of the box.
