Armin Ronacher's "P(doom)" post responds to a viral week of AI-risk discussion, citing Dario Amodei's apparent 10-25% probability of something bad happening and a Wikipedia page on 2026 OpenAI agent cyberattacks.

It targets users generating videos from timed prompts who want to check how closely the model follows intended actions and scenes.

A Reddit user measured MiniMax H3 text-to-video runs across four GPUs at four providers using identical weights, graph, and seeds, spending $1.67 on the runs. The test generated 5-second clips at 864x480 (0.4 MP).
