Searching images through patterns: An AI-powered serverless solution (DEV204)

Here's a detailed summary of the video transcription in markdown format, broken down into sections for better readability:

Current State of Generative Models

  • Tremendous advancements in the last two years (2023-2024) with new generation of models from companies like Meta, OpenAI, Anthropic, etc.
  • Newer models have better capabilities, higher quality, and are more cost-effective.
  • Key advancements:
    • Improved GPU technology enabling scaling of models to billions of parameters.
    • Advancements in data sets and training techniques, including use of synthetic data and multilingual models.

Key Features of Newer Models

  • Larger context windows (up to 300,000 tokens)
  • Multimodality - ability to process and generate content in text, image, audio, and video formats
  • Improved reasoning and inference capabilities, going beyond simple question answering
  • Agentic workflow - models becoming intelligent agents capable of interacting with external systems and performing autonomous actions

Text Models vs. Multimodal Models

  • Text models are designed to ingest and generate text based on patterns in textual data.
  • Multimodal models can process information from multiple modalities (text, image, audio, video) and integrate visual and auditory context.

Zero-Shot Prompting

  • Zero-shot prompting allows models to perform tasks immediately without requiring prior examples or task-specific training.
  • Benefits for business use cases:
    • Extracts information without needing previous examples
    • Allows faster implementation of new applications and features
    • Saves time and cost on data preparation and model training

Visual Examples

  • Visual question answering
  • Diagram interpretation
  • Image captioning
  • Grounding (identifying object locations in an image)

Customer Use Case

  • Digital printing company that creates and prints designs on fabrics for garments.
  • Key challenges:
    • Large, unstructured design file repository (few terabytes)
    • Manual process for creating mood boards and finding inspiration images
    • Reliance on external resources for images, incurring additional costs
  • Requirements:
    • Create a searchable attribute database of design files
    • Maintain privacy and security of the design files
    • Implement a low-cost, low-maintenance solution

Solution Approach

  1. Pre-processing on-premises: Segmenting and sampling images on local infrastructure to reduce processing costs.
  2. Generative AI model: Using Anthropic's Clover 3 (Haiku) model on AWS Bedrock for attribute extraction, instead of a machine learning model.
  3. Serverless Architecture:
    • Uploading image segments to S3
    • Processing images and storing attributes in Aurora Serverless database
    • Implementing a searchable interface using API Gateway, Lambda, and DynamoDB

Key Takeaways

  • Rapid development and implementation of the solution using serverless and managed services.
  • Generative AI models proved effective in extracting accurate attributes from a large, unstructured design file repository.
  • Pay-as-you-go pricing model and leveraging free tiers helped keep the solution cost-effective.
  • Constant feedback and a simplified, low-maintenance approach were crucial for the successful implementation.
  • Newer capabilities like prompt routing in services like Bedrock open up more possibilities for future use cases.
  • Cost is a significant factor, and intelligent use of cloud infrastructure can help reduce costs drastically.
