Mike Hostetler on Jido v3

<p>Mike Hostetler, creator of Jido and ReqLLM, is back for round three. Jido 2.0 hit the top of Hacker News and took his docs server down with it, and Jido v3 betas are already on Hex. We get into agentic back pressure, why models write better declarative Elixir, why most actors don't need an LLM at all, durable workflows with Jido Flow, and the multiplayer harness he's building on OTP.</p><p>Plus Grok Bots and personal agents, reverse engineering bad IoT apps, and live questions from chat.</p><p>00:00 - Introduction</p><p>02:56 - The Jido 2.0 launch and a Hacker News hug of death</p><p>06:27 - Lessons from Ralph Wiggum loops</p><p>08:51 - Why models write better Elixir</p><p>11:44 - Agentic back pressure</p><p>14:22 - Jido v3's Spark DSL</p><p>20:48 - When do you need 10,000 agents?</p><p>26:28 - Q&amp;A: A public actor mesh?</p><p>27:59 - Actors vs agents: Jido without an LLM</p><p>30:38 - Halo 2 NPCs and classical AI</p><p>33:36 - What's new in Jido v3</p><p>35:03 - Durable workflows with Runic and Jido Flow</p><p>39:34 - Property and fuzz testing with agents</p><p>42:27 - Who's building on Jido</p><p>44:27 - Q&amp;A: TermUI and the Jido harness</p><p>48:28 - DASP, the Durable Actor Session Protocol</p><p>50:39 - Q&amp;A: Pods, topologies, and the signal bus</p><p>55:01 - Grok Bots, Dots, and personal agents</p><p>57:20 - Reverse engineering IoT apps with an LLM</p><p>1:06:24 - LLMDB and LLM Catalog</p><p>1:07:51 - 600 PRs a month and vibe coded PRs</p><p>1:12:12 - The Founder Playbook skills repo</p><p>1:14:37 - Teaching and community after LLMs</p><p>1:17:31 - Will AI replace engineers?</p><p>1:22:57 - A hard lesson migrating Killswitch data</p><p>1:25:01 - What's next for Jido and the harness</p><p>Resources Mentioned:</p><p>- Jido: <a href="https://jido.run/?utm_source=elixir-mentor" rel="noopener noreferrer nofollow">https://jido.run/?utm_source=elixir-mentor</a></p><p>- Runic: <a href="https://github.com/zblanco/runic?utm_source=elixir-mentor" rel="noopener noreferrer nofollow">https://github.com/zblanco/runic?utm_source=elixir-mentor</a></p><p>- LLM Catalog: <a href="https://llmcatalog.dev/?utm_source=elixir-mentor" rel="noopener noreferrer nofollow">https://llmcatalog.dev/?utm_source=elixir-mentor</a></p><p>- Founder Playbook: <a href="https://github.com/getagentseal/founder-playbook?utm_source=elixir-mentor" rel="noopener noreferrer nofollow">https://github.com/getagentseal/founder-playbook?utm_source=elixir-mentor</a></p><p>- Killswitch: <a hr
