# Not Your Weights, Not Your Workflow

*I left a multi-agent refactor running overnight. By morning the model was gone, pulled out from under me by a government I don’t even vote for, on the other side of an ocean. This isn’t really a story about Anthropic. It’s a story about who’s actually holding the off-switch, and right now it probably isn’t you.*

So here’s how my morning went.

I had a job running. Not a toy, a proper codebase-wide refactor that had been grinding away continuously for the best part of two days. Multi-agent setup, left to run overnight, the kind of long, messy, long-horizon task that every model before this one just fell over on. [Claude Fable 5](https://www.anthropic.com/news/claude-fable-5-mythos-5) was handling it like it was nothing. Anthropic’s own launch notes talk about it compressing months of work into days, and honestly, on my own codebase, that wasn’t marketing. It was just what was happening.

Then I woke up. And the model was gone.

Not rate-limited. Not having a wobble. Gone. The thing I’d built two days of momentum on simply did not exist any more.

Turns out that on the 12th of June [the US government issued an export-control directive](https://www.anthropic.com/news/fable-mythos-access) telling Anthropic to cut off all access to Fable 5 and Mythos 5 for any foreign national. And because you can’t exactly sort a global user base by passport in real time, that meant pulling it for everyone. Including me, sat in Tyrol, watching my overnight run go cold.

Anthropic did the right things, for what it’s worth. They complied fast, they said out loud that they disagreed, and they’re fighting to get it back. About as well as a vendor can behave in that situation.

(As I write this it’s still down. Anthropic reckon it’s a misunderstanding and they’re trying to get it restored, so maybe by the time you read this it’s back up. Doesn’t change a single thing about the point I’m making.)

And it made absolutely no difference to me. That, right there, is the whole point of this post.

## The offer was the trap

Wind back a few days. Fable 5 dropped as the best model anyone had shipped, and the offer was lovely: [free on Pro, Max, Team and Enterprise from launch right through to the 22nd of June](https://www.anthropic.com/news/claude-fable-5-mythos-5), with paid credits only kicking in on the 23rd. Use the shiny new thing, get the rewards now, pay later. Simple. Who’s saying no to that?

So you don’t say no. You wire it in. You let it run your big jobs overnight. And your investment in the ecosystem gets deep, fast, because that’s exactly what a free window is designed to do. Then something completely outside your control happens, and the tool you’ve come to lean on just evaporates halfway through something that mattered. Boom. 💥 Now what?

And here’s the bit I want to be honest about, because the lazy version of this argument falls apart the second anyone clever pokes it.

I could not have run this job on open source. There’s no open-weights model out there today that touches Fable for this kind of long-horizon agentic work, and even if there was, I don’t have a room full of NVIDIA cards humming away in my workshop. Self-hosting frontier capability, as a one-man shop, is financially mental. So no. “You should’ve just used Llama” is not the lesson here. Anyone telling you that hasn’t tried it.

The lesson is smaller and a lot harder to wriggle out of. The only thing nobody can switch off is the thing you already hold.

Closed frontier models sell you capability, and the price is control. That’s a fine trade right up until the day it isn’t, and you don’t get to pick the day. Weights sat on your own disk can’t be recalled by a pricing committee, a quiet change of terms, or a letter from some agency. Everything else, you’re renting. On terms that can change while you sleep.

## None of this is new. It’s just my turn now.

If you’ve built on platforms for any length of time, you’ve watched this exact thing happen to other people. Now it’s my turn. The shape never changes: you build on someone else’s ground, and one day they move the ground.

Twitter, January 2023. Third-party clients [stopped working overnight](https://techcrunch.com/2023/01/12/third-party-twitter-apps-tweetbot-twitterrific-echofon-down/), no warning, no announcement, the API just quietly cut off. Tweetbot and Twitterrific, apps with twelve-plus years behind them and millions of users, [got yanked from the App Store and shut down for good](https://techcrunch.com/2023/01/19/twitterrific-tweetbot-app-store-removal-twitter-api). Tapbots said it best in their goodbye: closing “due to circumstances beyond our control.” Then a [pricing wall](https://www.socialmediatoday.com/news/twitters-new-api-access-charges-could-price-many-apps-and-researchers-out/644775/) came along and finished off whatever was left standing.

Reddit, June 2023. New API pricing meant Apollo, one of the best mobile apps anyone ever built, would’ve cost its solo developer [somewhere around 20 million dollars a year](https://techcrunch.com/2023/06/08/popular-third-party-reddit-app-apollo-is-shutting-down-as-a-result-of-reddits-new-api-pricing/) to keep running. So it didn’t. Gone on the 30th of June. Years of craft, ended by a line on a pricing page.

Facebook. Anyone who built on the Graph API lived through the [v1.0 deprecation](https://github.com/facebookarchive/fbconsole/issues/33) and then the [2018 lockdown](https://www.theregister.com/2018/04/06/facebook_shoots_itself_in_the_api/) after the Cambridge Analytica mess, where “scheduled deprecation” suddenly became “your working app is broken as of right now.” Refactor on their clock, or die on it.

And Shopify, which is the one closest to home for me, given I spend my days in e-commerce. Merchants get terminated for some alleged terms violation [with zero warning](https://dilendorf.com/blog/shopify-suspended-account-key-tips-for-merchants.html). Storefront dark, business stopped, that morning. And if they were on Shopify Payments, [the money gets frozen for anywhere from 120 to 365 days](https://easysellapp.com/blogs/wiki/shopify-store-suspended-appeal-recover). Years of work and your own cash, held hostage to a decision you had no say in.

Different platforms, same lesson every single time. You rented capability on someone else’s terms, and the terms changed.

## Why open still wins on the bit that matters

I’m not going to sit here and tell you open source is more capable than the frontier labs right now. It isn’t. Pretend otherwise and you lose every technical reader in the first paragraph. But capability isn’t the only thing that matters, and for anything you genuinely depend on, it isn’t even the main thing.

Open source wins on control, flat out, because it’s distributed. There’s no central kill switch. No single outfit, vendor or government, can reach across the network and wipe it off every machine at once. Once those weights are on your disk, they’re yours.

(Caveat for the pedants, and they’ve got a point: GitHub has geo-blocked sanctioned regions before, and there’s a live policy fight right now about restricting open model weights. So “impossible to block” is too strong. “Massively harder to block, and impossible to claw back once you’ve got it” is the honest version. It still wins.)

There’s a second thing closed systems can’t give you either. When the source is open, the whole world finds and fixes the bugs. You’re free to break it yourself, sure. But you’re also free to fix it yourself, and so is everyone else. With a closed model you’re not even allowed to lift the bonnet, never mind pick up a spanner.

## So where does that leave people like me?

You’d think a model that compresses months of engineering into days makes a developer like me pointless. This week argued the exact opposite, and loudly.

Who sets up a pipeline so that when the main model disappears overnight, it limps along instead of dropping dead? Who keeps the orchestration, the prompts, the data, the eval setup under their own roof, so the model is a part you can swap and not a single point of failure? Who picks up a half-finished refactor when the tool that was running it becomes literally illegal somewhere between midnight and breakfast?

Not the model. The person who planned for an off-switch they knew they didn’t control.

That’s the actual job now. Not typing the code, because for big stretches the AI genuinely is better at that than I am, and I’ve made my peace with that. The job is judgement. Knowing what you’re allowed to depend on, and building so that the rug-pull, when it comes, and it always comes, is an annoying Tuesday and not the end of your business.

This AI moment is genuinely amazing and also, let’s be honest, nowhere near as all-powerful as the hype keeps insisting. Will the robots take over the world? Maybe. But only for as long as the vendors are allowed to sell them to you. And this week showed exactly how fast that permission can be pulled, through no fault of the vendor, with you stuck halfway through something that mattered.

Don’t build on rented ground if you can help it. And where you can’t help it, which for frontier AI today is basically all of us, at least build like you know the landlord can change the locks while you’re asleep.

Because this morning, mine did.
