GPTkeras

GPTkeras aims to solve the struggles of guessing model configurations and hyperparameters when developing machine learning projects. Instead of manually tuning architectures and settings, you simply provide your training data (x and y), and this library leverages large language models (LLMs) specifically ChatGPT to automatically generate suitable layers and hyperparameters for your dataset.

The workflow is as follows:

• You provide your training data.
• The library uses ChatGPT to draft a Keras model architecture and select hyperparameters tailored to your data.
• It runs a training session and evaluates the results.
• The training results are then passed back to the LLM, which attempts to further improve the model configuration in subsequent iterations.

Another major challenge in machine learning experimentation is tracking changes to models and understanding how those changes affect results. GPTkeras addresses this by using the LLM to log and manage conversational context, so you can see how each modification impacts performance over time.

This toolkit wraps the OpenAI Chat Completions API and provides helpers for drafting model architectures, managing experiments, and logging conversational context when iterating on training runs.

Installation

pip install GPTkeras

Quick start

from GPTkeras import GPTkeras
