  • Provides visual grounding by highlighting bounding boxes and snippets.
  • Offers a developer-friendly SDK with automatic handling of long documents, parallel batching, and retry logic.
• Unique Features: Interprets layout, visual context, and structure, rather than just reading text.

5. Project 4: Embabel Agent Framework

• Main Topic: Intelligent agentic flows for JVM with AI-powered planning.
• Key Points:
  • Designed for building autonomous agents on the JVM (Java Virtual Machine).
  • Combines strong typing, domain modeling, and intelligent planning.
  • Defines goals, actions, and conditions, and uses a non-LLM AI planning algorithm to dynamically generate action sequences.
  • Supports replanning on the fly based on state re-evaluation.
  • Employs strongly typed domain models, conditions, and actions for better code quality.
  • Integrates with Spring and Spring AI, offering dependency injection, transaction support, and MCP (Model Context Protocol) integration.
• Unique Features: Dynamic, adaptable agent framework with AI planning, type safety, and JVM integration.

6. Project 5: Agents from Scratch

• Main Topic: Building AI agents with Langchain and Langraph.
• Key Points:
  • Focuses on hands-on learning and modular design.
  • Shows how to build agents step by step from the core up, providing control over every piece of the agent's functionality.
  • Uses Langraph's agent architecture, offering memory, human-in-the-loop pauses, and structured streaming.
  • Includes practical examples in Python and TypeScript (e.g., email assistance with triage, memory, and review workflows).
• Unique Features: Transparent ground-up approach to agent building with flexible modularity and advanced features.

7. Project 6: 20 (Twenty)

• Main Topic: Open-source alternative to Salesforce for customizable CRM.
• Key Points:
  • Offers freedom, flexibility, and community empowerment.
  • GPL licensed, self-hostable, and fully customizable.
  • Allows customization of objects and fields to match specific business needs.
  • Intuitive modern interface inspired by Notion and Airtable.
  • Includes workflows with triggers and actions, email/calendar integration, webhooks, APIs, and granular permissions.
• Unique Features: Community-driven approach with open roadmap and developer contributions.
