How systems change through use.
We study how an AI system can learn from experience without drifting away from the person it serves.
Learning without driftRifty is an independent research lab studying agents, adaptive systems, and the new forms of software developing around them.

Harness engineering with Codex starts with one coding task: supply usable context, bound its actions, inspect its changes, and leave a clear handoff.

Predictive, generative, agentic, and physical AI differ by what they produce, what they can change, and the controls their consequences demand.

Agentic AI in banking needs a six-class authority test for access, approvals, audit evidence, verification, and recovery.

Copilot spans prompt-led generation, agent builders, workflows, and autonomous code changes; the Agency Test shows which capabilities count as agentic.

Copilot Studio multi-agent orchestration needs narrow roles, bounded tools, tested handoffs, traceable execution, and a defined stop path.
ReadToday's software encodes a workflow and asks people to follow it. As agents become more capable, that relationship can change. Systems can learn from the people they serve, reshape themselves around real work, and improve without waiting for another product release. The model supplies general intelligence. The surrounding system gives that intelligence a place, a memory, and a way to change. Today, that system is usually called a harness. We think it will become a new form of software.
Our work focuses on the systems that allow agents to learn, act over time, and become particular to the people and organizations they serve.
We study how an AI system can learn from experience without drifting away from the person it serves.
Learning without driftWe study what should survive across tasks and how past experience should shape future work.
Across tasksWe study how agents pursue longer-running work across tools, interruptions, and changing conditions.
Long-running workWe study how to distinguish useful improvement from a system that has merely changed.
Evidence of progressWe study how intent, taste, and judgment can guide a system without being reduced to a settings page.
Human directionWe study what becomes possible when software is formed around a particular person or organization.
Particular systemsPeople spend too much time preparing work for AI: moving information into a chat, restating context, and translating a job into language the model can follow. Better systems should take on more of that burden.
Two companies may use the same model and still need very different memory, tools, permissions, and ways of making decisions.
A system that changes itself is not necessarily getting better. Improvement only means something relative to the person, organization, or purpose it serves.
Models will keep improving and being replaced. The accumulated understanding of how a company works should survive those changes.
Operating environments contain missing information, changing standards, delayed consequences, and decisions that do not have one correct answer.
Rifty maintains a private agent system that operates across tools, companies, and work that continues over time. It gives us a place to study what happens when tasks are ambiguous, requirements change, and the effects of a decision may not appear until days later. The system is not publicly distributed. We publish the parts that can stand on their own: findings, methods, evaluations, guides, and experimental tools.
Research questions come from operating work rather than constructed demonstrations.
Failures, corrections, and changing requirements become new experiments.
Work that generalizes beyond the private system is separated, documented, and published.
Findings and arguments from our work on adaptive agent systems.
Closer examinations of system behaviour, experiments, and design choices.
Methods for people building systems around their own work.
Ways to test memory, adaptation, reliability, and long-running agency.
Small releases for exploring one idea without adopting an entire system.
Problems we do not yet have good answers to, published so others can investigate them too.
