This model represents a step-function improvement on many benchmarks, and its training is ongoing.
Our internal model group arrived at the Navier–Stokes solution in 88 hours, using around 10,000 coordinating AI agents.
Throughout the effort, we maintained the strict safeguards—including monitoring and isolation—that we apply to all our frontier evaluations.
If you want to test Opus 4.7 in a proper harness like Pi and Claude Pro/Max auth is being weird, use this: https://t.co/kEsyaxO1RM
Install:
`pi install npm:pi-claude-oauth-adapter`
It’s the Anthropic OAuth / Claude Code compatibility adapter we use for Pi.
Quick demo of a (legal) way of using Claude Code subscriptions in Pi. Also a show n' tell of my little slopchop diff reviewer. Enjoy this sweet, sweet taste of Pi.
@robzolkos Yup they do, and I have a pipeline that automatically maps all the telemetry and fingerprinting, so that extension gets very close to the real cc shape without adding the system prompts, and gets around the filtering
Obviously there’s a ban risk; hence the disclaimer

Anthropic has started doing some very desperate filtering to filter out third party clients lol
They do a similar thing with pi (they check for pi docs in your system prompt lol)
Take a look at this if you wanna get around it and use your sub on pi: https://t.co/kEsyaxO1RM
THIS GUY LOST $200 IN ONE DAY BECAUSE THE STRING "HERMES.md" WAS IN HIS GIT COMMITS
HERMES.md is a real convention used in AI agent projects. it's a system prompt specification file. not some obscure edge case
he's on claude max 20x at $200 a month. yesterday claude code hit him with "you're out of extra usage" out of nowhere
his dashboard showed 13% weekly usage. 0% current session. 86% of his plan was sitting there untouched
but $200.98 in extra usage already burned through what should have been covered by his subscription
he tried logout & login, different models, fresh installs and nothing worked
anthropic support sent the ai bot (four rounds of the same scripted response). eventually they just gave up on him
so he started binary searching repos and commits manually on his own time until he found the trigger
the string "HERMES.md" in a recent git commit message
uppercase, with the .md extension, anywhere in your commit history
that's it
claude code includes recent commits in its system prompt and something server side flags HERMES.md and quietly routes you off your max plan onto API rate billing
> AGENTS.md? fine
> README.md? fine
> HERMES without .md? fine
> lowercase hermes.md? fine
> uppercase HERMES.md? you're getting charged API rates
he reported it. anthropic support acknowledged the bug three times, called it an "authentication routing issue", thanked him for finding it
then refused to refund the $200
so the man pays $200 a month for max, lost another $200 to a billing bug they confirmed, did anthropic's QA work for free on his weekend, and got a "thank you for your patience" in return
check your commit history before claude code quietly drains your account too
@om_patel5 lmfao they’ve started fucking regexing strings to detect third party clients
They do the same thing with pi docs (if it’s in the system prompt)

@robzolkos cause you notice a drastic improvement when agents only have exactly what they need and not more, esp skills, even 5.4 gets confused after like 15 skills (one trick is to leave breadcrumbs and not the entire list so they can find it) and define the high level philosophy
@robzolkos I feel like that’s way too many skills for most users, is there a way users can configure it /go through a setup wizard with an agent who knows the system so it can configure only the things they need? I’ve been putting together something similar but with just the must haves
