Trajectory.ai's continual learning platform, using Self-Distillation Policy Optimization (SDPO), enables companies like Harvey to train models that improve from real-world user interactions, marking a shift from static to living AI systems.

Editor's Notes


This week's videos converge on the theme of AI systems that evolve with user input, from Trajectory.ai's continual learning for enterprise models to Hermes Agent's integration with Obsidian for personal knowledge management. The AIE World's Fair 2026 announcement underscores the industry's growing focus on post-training, memory, and vertical-specific AI engineering, reflecting a broader move toward adaptive, user-driven AI workflows.

Key Takeaways

  1. Evaluate continual learning platforms like Trajectory.ai for domain-specific model improvement using user interaction data.
  2. Integrate AI agents with personal knowledge bases (e.g., Obsidian) to create living, self-organizing systems for task automation.
  3. Plan for AIE World's Fair 2026 to explore new tracks in auto-research, inference, and vertical AI applications.
  4. Consider open-source concurrent training stacks to accelerate deployment of continual learning in production.
  5. Leverage techniques like Self-Distillation Policy Optimization (SDPO) to capture expert trajectories and user corrections.
  6. Adopt multi-device, persistent AI workflows using VPS and sync tools for seamless agent-augmented productivity.
  7. Engage with token billionaire programs and leadership tracks at major AI engineering events to stay ahead of industry trends.

⚡️Every product of the future will be a living system — Ronak Malde, Trajectory.ai

Trajectory.ai, founded by ex-DeepMind and Windsurf engineer Ronak Malde, provides a platform for continual learning that enables companies to train models on real-world user interactions. By capturing expert trajectories and user corrections, Trajectory helps companies like Harvey train domain-specific models that improve over time, using techniques like Self-Distillation Policy Optimization (SDPO). The company also open-sourced a concurrent training stack to accelerate continual learning deployment.

Hermes Agent + Obsidian = The Ultimate Second Brain

The Hermes agent integrated with Obsidian creates a powerful second brain system where markdown files become "living files" accessible to AI agents for automated tasks. By storing skills, notes, and context in Obsidian and syncing them via a VPS, users can visually manage their knowledge base while delegating organization and task execution to the agent. The setup uses a VPS (Hostinger), Obsidian Sync, and Hermes agent to enable persistent, multi-device AI-augmented workflows.

6 Things to Know about AIE World's Fair 2026

The AIE World's Fair 2026 is the largest AI engineering event yet, with a full extra day of content, four expo stages, and a 4x bigger expo floor. The event introduces new tracks like auto-research, inference, post-training, pre-training, memory, and verticals such as finance, healthcare, and GTM. Key initiatives include a token billionaire program for high-volume users, a leadership track, and side events like a new engineer orientation and a kids' event.
