• Original title: Open Sauce 2026 | TheStandup

The Standup crew recaps two conferences they split up to attend — Better Software Conference in Sweden and Open Sauce in California — with Casey Muratori doing an impression bit and the bulk of the episode on Prime's Open Sauce main-stage event: 2,000 audience members collectively prompting LLMs to write Python bots that played Super Smash Bros. Melee live. It is a story about crowd-sourced AI chaos, a live on-stage production bug, and why the demo worked anyway.

Two conferences, one recap

The episode opens with Casey riffing on the name "Open Sauce" (New England accent gags, a fake computerenhance.com ad). Casey and Beginbot went to Better Software Conference in Sweden; Prime went to Open Sauce in California. Open Sauce is a maker/science-YouTuber convention now in its fourth year, filling the gap left after Maker Faire shut down — a place where people show off homemade builds: a self-positioning International Space Station model, 40-mph wheelchairs, backyard rockets, and dangerous-chemistry channels. Prime name-drops attendees: Michael Reeves, Doug Doug, William Osman, Backyard Scientist, Nile Red, Styropyro (Drake), Comment Etiquette, Code Bullet, Bash Buddy.

The main-stage event: 2,000 people prompt Melee bots

Prime got a 45-minute Saturday main-stage slot. The premise: a real GameCube runs Super Smash Bros. Melee on the big screen, but the four characters are driven by Python bots. Bots start as empty shells; the audience is split into four sectors, each scans a QR code, and everyone prompts an LLM to write their bot's code. Prompts are capped at 140 characters (OG-Twitter style). All prompts in a sector are mushed together, summarized by an LLM, then turned into bot code that is hot-swapped in.

Mechanics: the bots don't do screen vision — they read the game's internal state via libmelee, a mature library (heavily improved by the Melee community during COVID for lag-free, frame-perfect online play) that exposes full game state and allows frame-perfect inputs like wave-dashing. The LLM operates directly on that state. Getting from cold start to a running match takes ~6 seconds. Aggregating prompts took ~45 seconds to summarize and ~90 seconds to write code, using Grok 4.5 Fast for speed.

The four sectors were led by planted YouTuber "volunteers" with megaphones — Doug Doug, Eric (Comment Etiquette), Bash Buddy, and Code Bullet — who walked their sections shouting instructions.

The live production bug

TJ/Teach wrote most of the code and was still prompting last-minute styling changes minutes before going on stage, despite the system passing ~20 tests that morning. On stage, in front of 2,000 people, a never-before-seen bug hit: Cloudflare started returning errors. The fix was pure vibe-debugging — TJ opened the Cloudflare panel, copied the error, pasted "cursor WTF" plus the stack trace, hit enter, and it started working. Prime describes it as one of the most stressful moments of his life, stalling the crowd for 3-4 minutes. A second scaling problem: 2,000 people hitting the same site on mobile networks simultaneously nearly failed to load, and the QR codes weren't big enough for the back of the room to scan.

Highlights and outcomes

• Doug Doug (Donkey Kong): his audience made him grab Jigglypuff, put it on his head, and walk off the edge — killing both — a crowd favorite.
• Code Bullet (Fox) had a terrible early round but his audience re-ran with no changes; because everyone else changed their bots, he survived and won.
• Jigglypuff dominated early with "rest" spam; Prime thinks Fox is currently the strongest bot.
• The final came down to Captain Falcon timing out on a cloud, walking off, and dying — Fox won essentially by accident after ~45 seconds of both bots doing repetitive dance-like loops.
• Prompt chaos: people ignored instructions constantly. One losing prompt was just "rigged." A "for Elise" megaphone jingle became a recurring gag ("win for Elise"). The crowd repeatedly wanted Donkey Kong and Jigglypuff to kiss. Since bots were blocked from internet/tool calls, they couldn't just clone an existing best-bot repo; the training data theoretically contains strategy but is hard to coax out.

Wrap-up

The noise from the crowd was loud enough to interrupt green-room conversations. Prime teases a future Twitch-only version — Twitch chat vs. YouTube chat, or four streamers each mapped to a character in a "best chat" battle — and plans to force Casey (who has never played Melee) to be one of the prompters. Running theme: this crowd-sourced, last-minute, barely-tested spectacle was the exact "antithesis of a Better Software Conference," and it worked anyway.
