I've been out of the game for a bit but it's great to hear.

I worked at fb, and I'm 100% certain we sponsored VLC and OBS at the time. It would be strange if we didn't sponsor FFMPEG, but regardless (as the article says) we definitely got out of our internal fork and upstreamed a lot of the changes.

I worked on live, and everyone in the entire org worships ffmpeg.

i don’t think if you actually knew him as a person you’d think this was a reasonable perception.

1/ crypto signing is totally the right way to think about this. 2/ I'm limiting prompt injection by using chain of command: https://model-spec.openai.com/2025-12-18.html#chain_of_comma...

we have a "gambit_init" tool call that is synthetically injected into every call which has the context. Because it's the result of a tool call, it gets injected into layer 6 of the chain of command, so it's less likely to be subject to prompt injections.

Also, relatedly, yes i have thought EXTREMELY deeply about cryptographic primitives to replace HTTP with peer-to-peer webs of trust as the primary units of compute and information.

Imagine being able to authenticate the source of an image using "private blockchains" ala holepunch's hypercore.

hard to explain… we’ll keep going.

thinking about ways to deal with that but we haven’t yet done it.

you can set up really complex validation.

thanks for checking it out!!

Gambit hopefully solves some of that, giving you a set of primitives and principles that make it simpler to communicate intent.

I look at Gambit as more of an "agent harness", meaning you're building agents that can decide what to do more than you're orchestrating pipelines.

Basically, if we're successful, you should be able to chain agents together to accomplish things extremely simply (using markdown). Mastra, as far as I'm aware, is focused on helping people use programming languages (typescript) to build pipelines and workflows.

So yes it's an alternative, but more like an alternative approach rather than a direct competitor if that makes sense.
