Data collection and pre-processing

The structured and cleaned data are then used to build predictive models and derive insights from the datasets.

Model architecture

Next, we choose the best-suited model architecture based on your specific use case, whether it requires advanced natural language processing, image generation, or code assistance. This involves selecting the right foundation model (e.g., GPT-3.5 Turbo, Davinci, CLIP) and determining the structure of how it will operate within your product.
