RUNTIME LABS

About

Runtime Labs anchors language models in time and location. Our work is grounded in the conviction that time is the foundational primitive for memory and planning, the substrate where natural language intent can compile into deterministic, coordinated action.

Óra is our first release, an Integrated Planning Environment (IPE) for scheduling and discovering events on a shared timeline.

Research

We develop the infrastructure that enables language models to reason over time and operate on structured representations of real-world events. This includes systems for temporal indexing, memory persistence, and context retrieval.

Our objective is to build environments where models function as time-aligned partners in scheduling and planning.

Application

Óra is the first implementation of our work, moving language models toward event-based grounding in a persistent, time-structured state.

Óra is an environment where you can commit events and conversations to a shared timeline, storing memories and photos across digital and physical activities. Conversations and notes are saved as time-stamped event commits and durable records for personal and professional milestones.

Values

  • We commit to clear objectives and build for years, not cycles.
  • We exercise discipline in product release and external outreach. We maintain urgency in daily execution.
  • We allocate resources for compute, capital, and time thoughtfully and deliberately.
  • We value open-mindedness to diverse perspectives. The burden of proof is on inventors to build their inventions. The burden of utility is on the market to determine value.
  • We adapt quickly when diminishing returns in product or research become evident.
  • We embrace self-supervision and agency in learning and building: clear ownership and personal initiative.
  • We maintain a respectful environment that treats criticism and feedback as essential input to the process of invention.
