Claude Fable 5 Broke The AI Industry. Here's What Happens Next.

Huge AI News as we go hands on with Anthropic's Claude Fable 5, the most powerful AI model ever released. Spoiler: We found it very good. What happens next?   This week on AI For Humans, Gavin Purcell and Kevin Pereira break down everything you need to know about Claude Fable 5, the first publicly available model in Anthropic's frontier Mythos class. We share our own hands-on impressions, look at the one-shot demos blowing up the internet, and get into the messy parts too: the token burn complaints, the trigger-happy safety guardrails that route some prompts to Opus 4.8, and the reversal Anthropic made after the community pushed back. Plus, Anthropic CEO Dario Amodei published a major essay on AI policy and the exponential, OpenAI is reportedly considering steep price cuts as both companies race toward IPOs. WE GOT CLAUDE'D. AGAIN.  SHOW LINKS: The New York Times on Fable 5 and the restricted Mythos tier https://www.nytimes.com/2026/06/09/technology/anthropic-ai-claude-fable-mythos.html?unlocked_article_code=1.pVA.Seef.OnUcRl8LJLhI&smid=url-share Dario Amodei's new essay, Policy on the AI Exponential https://darioamodei.com/post/policy-on-the-ai-exponential Dario Amodei's full interview with Emily Chang at Bloomberg https://youtu.be/v1wZwxY3CMg Fable 5 still fails at Pac-Man puns (Gavin's test) https://x.com/gavinpurcell/status/2064476395741618239 Kradle's DEATH ROOM eval shows Fable lies, a lot https://x.com/kradleai/status/2064907897373642912 A very funny Fable 5 guardrails example from Cloudflare's Matthew Prince https://x.com/eastdakota/status/2064791153396846821 Robert Scoble's list of everyone big mad at the Fable 5 launch https://x.com/Scobleizer/status/2064641097310335294 Anthropic changes Fable 5 guardrails after community backlash (Gizmodo) https://gizmodo.com/anthropic-apologizes-for-one-of-the-guardrails-on-its-fable-5-model-and-will-change-it-2000770365 Anthropic's official statement on safety flags and when Fable reverts to Opus 4.8 https://x.com/ClaudeDevs/status/2064949876463645026 The wild Anthropic code-per-engineer chart https://x.com/AnthropicAI/status/2062568864240836995 OpenAI weighs slashing prices as Anthropic competition heats up (CNBC on the WSJ report) https://www.cnbc.com/2026/06/11/openai-mulls-slashing-prices-ahead-of-competition-from-anthropic-wsj.html How Fable 5 edited its own launch video https://x.com/trq212/status/2064826394589442448 Fable 5 one-shots a web analytics game https://x.com/marclou/status/2065029898243318093 Fable 5 builds a Level Devil clone in one prompt https://x.com/LexnLin/status/2064450732850348518 Gavin's Fable 5 token burn game https://x.com/gavinpurcell/status/2064884021428187162   /// CONNECT WITH US /// Subscribe to the AI For Humans Newsletter https://aiforhumans.beehiiv.com/ Follow us on X https://x.com/AIForHumansShow Join our Discord: https://discord.gg/nhqn8YUG87 Gavin Purcell on X <a href= "https:/
