Heard, Chef!
Heard Chef is a voice head chef that runs the timing of a whole multi-dish dinner, for cooks whose hands are busy and eyes are on the pan. Pick a menu and a serving time: Chef plans every dish backwards and calls each step out loud when it's due. When something slips, just say "Hey Chef, the curry needs ten more minutes" and the whole dinner re-plans: serving flips from 8:00 to 8:10 and every step slides. You can interrupt Chef mid-sentence, ask cooking questions, and add or drop dishes mid-cook. Off-topic questions get steered back to dinner. Talk your own family recipe through, and Chef turns it into a timed recipe with suggestions. Built on two AssemblyAI products in one static web page. Universal-Streaming is the always-on "Hey Chef" ears and recipe dictation. The Voice Agent API is Chef's brain and voice, with seven in-browser tool calls and a text-in recipe scribe. A deterministic planner does the maths, backed by 313 tests and 16 live API tests.

The Specialist-Options market-maker+convexity desk
Most trading agents guess direction — will a stock go up or down over a few days? Over a short competition window, that's close to a coin flip. The Specialist doesn't guess. It runs two independent strategies side by side on Alpaca paper trading. Specialist Mode acts like a real market maker: it posts resting limit quotes on liquid, near-the-money options across a small basket (SPY, QQQ, AAPL, NVDA, TSLA), capturing the bid-ask spread whichever way the underlying moves. Every fill triggers an immediate equity hedge, keeping the book close to delta-neutral. Convexity Mode runs in parallel, selling defined-risk vertical spreads and iron condors when implied volatility looks rich, so the account keeps generating real trading activity even on a quiet day for market-making fills. An LLM (via Featherless) decides which symbols to quote and how wide, reads scheduled macro events and live news sentiment into a risk posture — but it never places an order. A deterministic risk gate sits underneath every decision: hard caps on portfolio delta/vega/gamma, a daily drawdown circuit breaker, a kill switch, and reconciliation logic that specifically guards against Alpaca's documented ~10% random partial-fill rate on multi-leg orders, which can otherwise leave a spread as an unbounded naked position overnight. Everything is written to an append-only SQLite ledger and rendered on a static dashboard with zero credentials in the browser. Several of its safety rules exist specifically because running it live — not reading documentation — surfaced real platform constraints (Alpaca rejects naked short calls; it blocks a resting buy and sell on the same contract at once) that shaped the final design.
