Your laptop doesn't need CUDA to ship GPU workloads. @runpod's Flash now ships a Nix flake: `nix run github:runpod/flash`. No clone, no virtualenv. Nix pins your local toolchain, Flash runs your code on a GPU.

Last week our co-founder and CEO @ronefroni joined “The Case for Open Source Models” panel at Leverage Israel during SF Tech Week. Big thanks to his fellow panelists and moderator for a great conversation on why open models matter, and what it takes to run them in a way teams can actually trust and reproduce. Thanks to Leverage, Onyx Security and @speedrun for bringing the room together!

What happens when you point a coding agent at a real, messy codebase and ask it to sort out the dev environment? Justin (Our DevRel Lead <3) put our `floxify` skill to the test on Mastodon, a challenging repo (with Ruby, Node, PostgreSQL, Redis, native dependencies, multiple services) to build from source. The skill went through the repo, figured out what it needed, built the Flox environment, checked it, hit a few problems, fixed them, and kept going until `flox activate` worked. All in just a couple of minutes. The result: a declarative, reproducible Mastodon environment without using containers, and without Justin (or an agent) having to reverse-engineer the setup from scratch. He also tried the `flox` skill for a new project, starting from what he wanted to build rather than an existing codebase. Two different starting points, same idea: Give the agent what it needs to quickly set up the runtime environment. This way it spends tokens running and testing code instead of debugging setup. Justin wrote up the whole experiment, including what worked, what broke, and what the skills did about it 👇 buff.ly/VBYNYQc

Flox v1.16 is out, with two additions: `flox run` and a new plugin system for secrets management. `flox run` lets you run packages from the Flox Catalog without creating an environment or installing anything: `flox run jq` Flox resolves the package that provides the command and runs it on-demand. If multiple packages provide the same command, you can select one and Flox will remember your choice. Or you can specify it explicitly with `--package`. This is especially useful in CI: `flox run --package python312 -- python hello.py` The new secrets plugin system provides pre-built integrations with 1Password, HashiCorp Vault, OpenBao, Infisical, and other providers. Secrets remain with the upstream provider; Flox retrieves + makes them available in the environment at activation. No custom logic required. Learn more about `flox run` and secrets management with Flox plugins 👉 buff.ly/FdFbDLN

Wrapping @DevOpsDaysPDX 2026! TL;DR: the platform work you've already done is what saves you when AI hits your pipeline. Best talk for me: Daniel Sauble's Nix ignite. Containers fix reproducibility yet wreck DX. Nix fixes both, down to glibc. Also got to meet the Flox folx IRL!
