This is a simplified guide to an AI model called Codellama-34b-Python maintained by Meta. If you like these kinds of analysis, you should join AImodels.fyi or follow us on Twitter.

Model overview

codellama-34b-python is a 34 billion parameter language model developed by Meta that has been fine-tuned for coding with Python. It is part of the Code Llama family of models, which also includes variants with 7 billion and 13 billion parameters, as well as instruction-following variants. These models are based on the Llama 2 language model and show improvements on inputs with up to 100k tokens. The Code Llama - Python and Code Llama models are not fine-tuned for instruction following, while the Code Llama - Instruct models have been specifically trained to follow programming-related instructions.

Model inputs and outputs

codellama-34b-python takes text prompts as input and generates continuations of that text. The model supports input sequences up to 100,000 tokens long and can be used for a variety of programming-related tasks, including code generation, code completion, and code understanding.

Inputs

Prompt: The text prompt to be continued by the model.
Max Tokens: The maximum number of tokens to be generated in the output.
Temperature: A value controlling the randomness of the generated output, with lower values producing more deterministic and coherent text.
Top K: The number of most likely tokens to consider during sampling.
Top P: The cumulative probability threshold to use for sampling, which can help control the diversity of the generated output.
Repeat Penalty: A value that penalizes the model for repeating the same tokens, encouraging more diverse output.
Presence Penalty: A value that penalizes the model for generating tokens that have already appeared in the output, also encouraging diversity.
Frequency Penalty: A value that penalizes the model for generating tokens that are already highly frequent in the output, further encouraging diversity.
