Just finished week 1 at @Fern_Labs . The goal? Build agents that can build and run startups autonomously. But before that, I need to see what Fern can actually do. While most SWE agents can build UIs, I’m skipping that and going straight to complex, AI-powered ideas from my head. 🧵Let’s see what Fern can do so far 🧠


We often use "Make Slack" as an internal benchmark. Absolute joy as I'm in Japan this week to get a ZERO LATENCY AUDIO CALL on a Fern-built Slack clone from the @Fern_Labs team in London! This is a full end-to-end private hosted audio call, built entirely by Fern agents! This full Slack clone took Fern 5 hours (with ~10 mins input time from the user) to build from SCRATCH. NO templates. NO special prompting. Pure Fern agents that work. I asked Tofunmi, our cracked engineer who made this, how long it took him, how much he had to prompt. "Oh prompting, maybe like 10 minutes in total, taken ~10 round trips, should've been ~7 though, prompts have been really short i.e. "... isn't working"" t-minus 3 weeks till we deprecate our Slack? We'll open-source the full repo when we do if your org would like to host your own - comment below if interested! @Fern_Labs agents built this entirely from scratch with @flydotio.

Kimi has identity issues in English. Consistently claims to be Claude from Anthropic when using tools. Could have a few different causes, but also bad for Moonshot as Kimi keeps attributing its work to Claude. Repro and deep-dive in thread 🧵

They don’t want you to know you can watch White Lotus while an army of @Fern_Labs agents builds your weekend project



App Spotlight: Reading Comprehension Exercise Generator Great app made by a teacher. It's hard to find good targeted reading comprehension materials for middle schoolers. Fern made an app that creates texts, questions, and answer schemes that you can print out to use in class! Prompt to live app took ~20 minutes. We'll now be generating similar apps for IB/A-level/AP, ping if you have other ideas!
