Building Otto

A series of technical posts written by CD Wang, Otto's CTO. Read more to learn about how Otto is built.
Every Gate Passed

Our maintenance loop filed a correct ticket about a fraud-decline error message, and the fixer implemented it faithfully. I still could not merge it. An account of why an automated harness can only ever verify execution rather than intent, what a real traveller lost to that gap, what we have changed in Connie since, and the one piece that would have caught it that we have not built.

Who Decides What's Worth Remembering? Notes in the Margin of a Memory Paper

A practitioner's margin notes on Meta's proactive memory-agent paper. The real question isn't what an agent stores — it's who decides a memory is relevant right now: the actor that owns the goal, or an observer that may notice what the actor forgot. Neither answer works cleanly.

What 100k autonomous travel conversations taught us about stateful API chains

How Otto, a fully autonomous travel agent, handles long chains of stateful supplier API calls, and the hard-won lessons (classify by the double-call test, reconcile never retry, enforce budgets at the transport boundary, discover expiry, model invalidation as a graph) now open-sourced as chain-re-action.

The Duck Test for AI Assistants: Why "You Are an Expert ___" Isn't Enough

A persona makes your Custom GPT or assistant look and quack like an expert for free — and that's the trap. A no-code build checklist first, then why each step matters.

Read more
The Loop Is the Product

Loop engineering is being framed as a coding-agent trick. The more important reading is that the loop is a product pattern: an autonomous agent is a loop closed over a human's goal tightly enough that they don't have to stay in the turn. A first-person, skeptical take, with Otto as the example.

When AI Handles Execution, Skin in the Game Lives Where the Reserves Live

Taleb argued that decision-makers should bear consequences. AI agents structurally cannot. So where does skin in the game live in an agentic product? An argument that insurance - field agent, underwriter, carrier, policyholder - is the right model for how Otto and its human travel agents share risk.

The Prompt Isn't Dead. The Goblins Proved It.

The Future Programming Language Is a Conversation

We've been versioning the wrong thing. The generated code is becoming a runtime artifact. The real work — the questions, the decisions, the context — is the conversation. And it's not under version control.

When Could Your Agent Just Buy the Ticket Itself?

You've thought about this: at what point should your AI agent just act? Book the flight, pick the hotel, send the message - without asking first. The obvious answer is "when it has permission." The right answer is more interesting. Agency isn't a permission level. It's the degree to which an agent has internalized what you actually care about. For decisions with competing tradeoffs, that calibration - not consent - is the real bottleneck. This piece is a problem statement, not a solution.

The Harness Architecture: How to Split Agents, Skills, and Tools

Everyone's talking about harness engineering. But if the harness is just the prompt, the context, and the eval pipeline - what exactly are we calling an "agent"? And here's the question to all those building agents: with a powerful foundation model and a set of API endpoints wrapped as tools, where do you build your moat, and what do you share? Look at Claude Code next to Grok for code. Similar underlying models capability, roughly. Wildly different results. I believe how you build the agent is turning out to matter as much as the model itself. This post is my attempt to make sense of where the lines should go.

Why BFS-Style Test-Time Search Isn’t Enough - and Why RLVR Matters for Reasoning Agents

Test-time BFS has become a popular way to boost reasoning in LLMs, but it secretly assumes a fixed and fully-known task distribution. Taleb showed why that assumption fails in real-world environments, where distributions shift and sampling fools us. RLVR updates the policy itself, so exploration becomes learned, cumulative, and cheaper over time.

Engram - maybe a New Axis for LLMs

Searching SF → NYC isn’t scrolling through 250 flights - it’s navigating 5,000+ possibilities! Every route, cabin, fare rule, and baggage policy spawns a new branch in the search tree, and that’s before loyalty status, seat availability, or the real question: do you at least get snacks?

Escaping LLM Collapse: Why AI Keeps Recommending the Same 3 Flights (and How We Broke It)

Model collapse happens when an LLM optimizes for probability instead of relevance - diversity dies and only the statistically common answers survive. To break that behavior, we override the model’s default priors with structured context, domain rules, and explicit constraints. Without that, Otto would still be suggesting “United at 9 AM and the Marriott by the airport” for every trip.
