Talk "Teaching a Weak Code Model to Improve with Reinforcement Learning"โ
โ๐ค Daniel (Thi) Graviet, Machine Learning Engineer at Daytona
โโโโโโโโOutline:
โWhat happens when you give a small, weak code model a way to learn from its mistakes?
โIn this live demo, we'll use Group Relative Policy Optimization (GRPO) to fine-tune a code model through trial and error. The model will generate solutions to coding tasks, run them in isolated Daytona sandboxes, and receive rewards based on whether its code passes the tests.
โWe'll walk through the full loopโfrom generating completions and grading them in parallel, to feeding the rewards back into training and watching the model improve over just a few steps. Along the way, we'll explore why reinforcement learning for code is challenging, how sandboxed execution makes automated feedback possible, and what it takes to make these systems reliable enough for a live stage demo.
โYou'll leave with a practical look at:
โ- How GRPO trains models without traditional labeled answers
- Using Daytona sandboxes as safe, parallel code graders
- Designing simple, explainable rewards for coding tasks
- Observing a model's performance improve in real time
โโ๐ 5:50 pm โ 6:05 pm
Talk "Build a Team of AI Specialists - from Slack"
โ๐ค Ryan Cooke, Engineer Manager at WorkOS
โโโโโโโโOutline:
โAI tools give everyone the same general-purpose assistant. Atlas lets everyone at WorkOS create specialists and recurring workflows specific to their tasks at hand, directly from Slack.
โIn this live demo, Ryan will show real tasks across connected systems, easily turn it into scheduled automation, and create a named AI teammate with its own instructions, memory and restricted tool access.
โThis turns successful conversations into durable agent operations, workflows that keep running and specialists anyone can call by name.
โโ๐ 6:05 pm โ 6:20 pm
Talk "Self-Improving Agents from Behavioral Exhaust"
โ๐ค Edward Irby, Staff Software Engineer at You.com
โโโโโโโโOutline:
โAn agent that improves itself by reading its own traces. Every event selected, every thread suspended, every deadlock encountered becomes training data for its own behavior โ not through weight updates, but through structured iteration across two mutable surfaces: behaviors and skill instructions.
In a Daytona sandbox space, the agent authors candidate behaviors and skills, and a deterministic gate scores each variant from the trace alone โ pass, fail. The winners are promoted into a space as plugins; the rest are discarded. The kernel itself never rewrites in place โ it grows by composition.
Behavioral programming makes this native: behaviors compose as independent scenarios that the arbiter re-evaluates fresh each step, so adding or removing one never corrupts the rest. Every candidate is verified for deadlocks before it runs โ self-modification can't break confluence.
The result is a neuro-symbolic harness: neural generation proposes, symbolic verification disposes โ and the exhaust is the teacher.
โโ๐ 6:20 pm โ 6:35 pm
Talk "Give Your Agent a World, Not a Mock"
โ๐ค Ritiz Tambi, Senior AI Engineer at Veris AI
โโโโโโโโOutline:
โSandboxes hand an agent a computer in seconds. Coding agents are fast, and a fleet turns out a week of changes in an afternoon. Verification is the constraint now. An agent's code calls Stripe, or Postgres, or the CRM, and nothing answers. So it writes a mock, asserts against its own mock, and hands the PR to a human to check. The more services the code touches, the more of it nobody has actually run. Mocks can't close that gap because they hold no state, staging can't because a fleet can't share one, and a vendor's test mode won't fail when you need it to. So we built the other half. Not mocks, a world. Every agent gets its own. A full stack of everything it depends on, where the clock, the failures, and the credentials behave like the real ones. It seeds the history it needs, runs the flow, breaks it on purpose, checks what actually happened. Then it promotes that world so the rest of the fleet starts from something closer to production, catches the bugs that only show up there, and ships PRs that hold.
โโ๐ 6:35 pm โ 6:45 pm
Talk "How Sandboxes Power a Software Factory"
โ๐ค Daria Shifrina, Member of Technical Staff at Obvious
โโโโโโโโOutline:
โYou've gotten AI to write code for you. Where does all that code run? At Obvious, thousands of isolated sandboxes turn our product from a fast pair programmer into a software factory. I'll cover how that architecture looks, why we put an OS provider layer underneath it, and where this goes: a sandbox marketplace for your software factory.
โโ๐ 6:45 pm โ 6:55 pm
Talk "Stop talking to your AI Agent! Teach it instead."
โ๐ค Marina Trajkovska, GTM Engineer at Vellum
โโโโโโโโOutline:
โThe way we interact with AI agents is broken. You type instructions, they follow them, you repeat yourself. Companion mode changes that. You talk, you type, you demonstrate on your machine while the agent watches your screen. It learns the skill from what you do, not what you say.
โโโโโโโโโโโโโโโโ๐ 6:55 pm - 8:30 pm
