Data curation for post-training

Odyssey AI is an AI lab headquartered in Palo Alto that builds general-purpose world models. These models predict outcomes in physical space, unlike large language models that focus on text prediction. Odyssey's technology creates interactive video streams that respond to user inputs in real time, simulating real-world scenarios. Key applications include robotics training, gaming, autonomous vehicles, scientific research, and national security.

Trajectory builds a platform for continual learning, letting companies post-train open-source AI models on real user interactions so products improve weekly instead of staying static between major model releases. Founded in 2025 by former Google DeepMind, Apple, OpenAI and Meta Superintelligence Labs researchers, it works with AI-native customers including Decagon, Clay and Harvey to ship narrowly-tuned models that outperform frontier labs on customer-specific tasks.
