Back from @modal eng hackathon in Mohonk. My team built a Portal-themed AI escape room, all running on Modal. The twist: your AI helper, GLaDOS, Is secretly trying to phish you for more permissions. 60+ eng played and we won “For the Love of the Game” category. Check it out:

I've been doing infratourism before I knew it was a concept. If you're fascinated by innovative ways humans have designed and built infrastructure (especially physical ones like water and transportation systems) to improve our quality of life, make it a focus on your next trip!

Qwen 3.8-Max is live on Modal, with the full 1M context window and a custom DFlash speculator under the hood. Love seeing our launch partner Modal go all in from Day 0!⚡️ 2.4T parameters. 1M context. Somehow, still just a Modal call away. @modal

The Github breach was due to a single employee using a poisoned VSCode extension. Compromising employees is often the easiest way into systems. If you want to work on cybersecurity at the forefront of the AI infra space, Modal has 3 open security roles! jobs.ashbyhq.com/modal?utm_s…

1/ We are sharing additional details regarding our investigation into unauthorized access to GitHub's internal repositories. Yesterday we detected and contained a compromise of an employee device involving a poisoned VS Code extension. We removed the malicious extension version, isolated the endpoint, and began incident response immediately.

Added a fun lil widget to the LLM Engineer's Almanac -- a "Token Timing Simulator" so you can get a visceral feel for what a benchmark perf number means. Here's @_dcw02's latest work with @zhijianliu's DFlash technique in @sgl_project -- ~1k TPS! modal.com/llm-almanac/token-…

Did GitHub start packing their Actions runners more tightly or give us worse hardware? For some reason the flake rate for integration tests in my team's monorepo that had certain assumptions about timing has increased along with other weird flakiness failure modes.
