I am migrating my company to private open source AI and building custom tooling, orchestration, an IDE and harness around it. The commercial labs have show it’s far too risky to build on top of them.
With the labs moving into the app layer every interaction with the API related to product development or innovation is data they will steal and use to compete against you by adding those features to their everything apps. No one would hire a knowledge firm (law firm, accountants, management consultants) if they could steal your information and give it to your competitors. Their actions have remained me that we can’t tolerate that with AI systems.
With spaceX buying cursor and Google buying windsurf, and gathering all the developer interaction as training data, there is too much risk that development process itself will be rug pulled.
Here's a copy of the letter that Commerce sent to Anthropic (note who it'a NOT addressed to...)

June 30, 2026
Tom Brown Chief Compute Officer Anthropic 548 Market Street San Francisco, CA 94104
Dear Mr. Brown:
Since the issuance of my previous letters, dated June 12, 2026 and June 26, 2026, Anthropic has taken steps in close coordination with the U.S. government to address the risks associated with Claude Mythos 5 and Claude Fable 5. Among other things, Anthropic has agreed to proactively detect and address security risks associated with the models; to work diligently with the U.S. government on protocols and standards and releases for Mythos, Fable, and future models; and to inform the U.S. government of any malicious activity.
In light of these actions and commitments, as well as the Bureau of Industry and Security's evaluation of the diversion risks now presented by Claude Mythos 5 and Claude Fable 5, the controls in the June 12 letter are withdrawn. A license is no longer required for the export, reexport, or in-country transfer, including deemed export or deemed reexport, of the Mythos or Fable models.
Commerce reserves the right to reevaluate the decisions made in this letter and the necessity of reimposing a license requirement, should circumstances change or should Anthropic fail to adhere to its commitments.
If you have any questions about this letter, please contact me or the Under Secretary of Commerce for Industry and Security, Jeffrey Kessler, at (202) 255-1864.
Sincerely,
Howard W. Lutnick

Jeff is now going to have to change his number. Can’t imagine all the calls or messages he must be getting now
For those who haven't been following this closely, who is the missing addressee?
Dario Amodei (Anthropic's CEO) had previously been directly liaising with the government and apparently it wasn't going well.
Any news why?
They don't speak the same [proverbial] language essentially. Dario and the WH talk about this stuff completely differently.

To be fair is quite hard to actually understand what this White House is saying most of the time
Incoherence is a feature, not a bug, of authoritarians
(not necessarily implying it's conscious strategy, authoritarians tend to be actual incoherent dumbasses)
I'm fairly certain which side of the conversation I'd have trouble understanding. I have trouble understanding it all the time.
He's the one who led the choice to refuse working with the gov for surveillance or defense, and it led to that block right after.
I have no proof but I assume he believes at least some of what he's preaching (which doesn't mean he won't fold, at the end of the day it's an american company anyway).
Brown is probably more of a diplomat, "Sure, but not now" goes a lot further than "No, never", though it has the issue of kicking the can down the road.
> He's the one who led the choice to refuse working with the gov for surveillance or defense
This is false and just Anthropic being good at PR. He's happy to let it be used for airstrikes on Iran for example, just wants to keep a human in the loop. So the AI will say 'I am extremely sure this building (a girl school) is a military base' and the human will say 'I am being asked to carry out more airstrikes and who am I to question AI' and will bomb a school with Amodei then washing his hands.
You've mentioned the Iran airstrike twice now. Do you have a source for them using an LLM for their "intelligence" / decision making?
You can find a source for it being used here [1] though parent is misrepresenting it either on purpose or by lacking understanding, I stand to my point above, the timeline is
1. the US used it, in venezuela then to prepare Iran
2. it became public through journals reporting it, but they didn't really hide from it afterwards and told explicitely what and who they used, naming anthropic
3. Diego (the CEO) answered by saying this violate terms and the US is not allowed and should stop that immediately, publicly
4. They have a talk, and while concessions are made it blocks not about war with ennemies but about surveillance at home, which Diego refuses to let go
5. Trump reacted by calling Anthropic a "Radical Left AI company run by people who have no idea what the real World is all about"
6. Peter Hegseth annonce they will stop using it but asked for a stop gap deal "Anthropic will continue to provide the Department of War its services for a period of no more than six months to allow for a seamless transition."
7. Open AI annonce a deal with the governement four and a half HOURS later, with totally cool safeguards "We think our agreement has more guardrails than any previous agreement for classified AI deployments, including Anthropic's", journals note that "OpenAI's new Pentagon deal doesn't explicitly prohibit collecting Americans' publicly available information - a sticking point that rival Anthropic says is crucial for ensuring domestic mass surveillance doesn't take place"
8. In totally unrelated news, Anthropic new models get banned for exports in a move the US has never done before, no other company has their models banned
And now
9. Anthropic change the person talking with the gov to Brown
10. After a bit anthropic models start being unbanned

What part am I misrepresenting, Anthropic CEO explicitly states he's ok with military use as long as there's a human in the loop[1].
He states the Iran school strike 'doesn't even violate our red lines'.
Can you clarify what am I misrepresenting please?
Thanks for the break down. I somehow missed the 2nd point. Crazy that they just used an LLM like that.
