## Model overview

`codellama-34b-instruct` is a 34 billion parameter large language model developed by Meta, based on the Llama 2 architecture. It is part of the Code Llama family of models, which also includes versions with 7 billion, 13 billion, and 70 billion parameters. These models are designed for coding and conversation tasks, providing state-of-the-art performance among open models. The models have infilling capabilities, support for large input contexts, and zero-shot instruction following ability for programming tasks.

Similar models include the [codellama-70b-instruct](https://aimodels.fyi/models/replicate/codellama-70b-instruct-meta) with 70 billion parameters, the [meta-llama-3-8b-instruct](https://aimodels.fyi/models/replicate/meta-llama-3-8b-instruct-meta) with 8 billion parameters, and the [meta-llama-3-70b](https://aimodels.fyi/models/replicate/meta-llama-3-70b-meta) and [meta-llama-3-8b](https://aimodels.fyi/models/replicate/meta-llama-3-8b-meta) base Llama 3 models.

## Model inputs and outputs

The `codellama-34b-instruct` model takes a variety of inputs, including prompts for code generation, conversational tasks, and instruction following. The model supports input sequences of up to 100,000 tokens.

### Inputs
- **Prompt**: The initial text or code to be used as a starting point for the model's response.
- **System Prompt**: An optional prompt that can be used to provide additional context or guidance to the model.
- **Temperature**: A parameter that controls the randomness of the model's output, with higher values resulting in more diverse and exploratory responses.
- **Top K**: The number of most likely tokens to consider during the sampling process.
- **Top P**: The cumulative probability threshold used for nucleus sampling, which limits the number of tokens considered.
- **Repeat Penalty**: A penalty applied to the model's output to discourage repetition.
- **Presence Penalty**: A penalty applied to the model's output to discourage the repetition of specific tokens.
- **Frequency Penalty**: A penalty applied to the model's output to discourage the repetition of specific token sequences.

### Outputs
- **Text**: The model's generated response, which can include code, natural language, or a combination of the two.
