Anthropic accidentally leaked a draft blog post revealing its next flagship model, Claude Mythos — a large, compute-intensive model that is "very expensive for us to serve, and will be very expensive for our customers to use," with the company working to make it "much more efficient before any general release." That's a notable admission for a model Anthropic itself describes as a "step change" above its existing Opus line.
The timing was awkward. The same week, Anthropic reduced the power of its service during peak hours to balance demand with its server capacity — drawing outrage from developers who pay up to $200/month for Max plans and found their sessions burning out in under 90 minutes. OpenAI moved swiftly: it doubled usage limits for its rival coding tool Codex for the following week.
Resolving the crunch will require capital. Anthropic may need to rent servers on the spot market rather than reserved capacity, which is typically far cheaper — a move that could erode gross margins. The longer-term fix: Google is in talks to provide construction loans for a $5 billion-plus data center in Hubbard, Texas, operated by Nexus Data Centers and leased to Anthropic. A consortium of banks is competing to provide project financing by mid-2026, with Google's backing expected to lower borrowing costs. The 2,800-acre facility is expected to deliver around 500 megawatts of capacity by late 2026, with long-term expansion potential to 7.7 gigawatts.
Bonus chaos
On the same day OpenAI closed its round, Anthropic accidentally published 512,000 lines of Claude Code's source code to the public npm registry — then issued DMCA takedowns targeting over 8,000 GitHub repositories to contain it. The irony was not lost on anyone: Anthropic had previously trained its models on millions of pirated books, ultimately settling with authors for $1.5 billion. As one TBPN guest put it — if someone rewrites the leaked Claude Code in another language, Anthropic likely can't touch them. That's exactly the argument Anthropic used to justify training on copyrighted books. The "ethical adult in the room" is now on the other side of the IP debate.
