AI News, Nov 6: Opus 5.5 doubts, an email leak in Claude Code, and free code that doesn't sell

Developers say Opus 5.5 got worse and costlier

A post on r/ClaudeCode (1,168 upvotes, 459 comments) says Opus 5.5 now takes longer to get things right and burns more tokens than at launch. The most upvoted reply (422 votes) guesses Anthropic quantized the model to free compute before a new release. Nothing confirms it.

If your pipelines run on Claude, pin the model version, keep a small regression test you can rerun, and set a token budget per job, so a silent change shows in your numbers before it shows in your output.

Limit: No statement from Anthropic; the only benchmarks found are on secondary blogs and unverified. Source: r/ClaudeCode ↗

Claude Code may put your email in its web requests

A GitHub issue (#107757, 300 reactions) and a Hacker News thread (865 points) report that Claude Code sends a User-Agent header containing the user's email when it searches the web. The issue's author says it brings dozens of spam emails a day.

For agencies running agents on client work: check what your automations send in your name, and give agents a dedicated address, not your main inbox.

A free open source clone of a SaaS found no users

On r/vibecoding, a builder vibe-coded an open source alternative to a popular SaaS, with parity on the core features, and got no traction. Top reply (158 votes): why not host it and charge less than the incumbent? Another (63): most people don't want to be sysadmins.

Code is getting cheap to write. People still pay for convenience: hosting, security, support. Sell that part.

Readers are tired of READMEs written by Claude

A post on r/ClaudeAI (463 upvotes) asks vibe-coders to rewrite the READMEs Claude generates for them. Looking for VR headset scripts, the author found every README dense, padded and hard to read. A reply with 164 votes jokes that READMEs are now written for other Claudes.

A README is a first pitch, like a landing page. Write the opening yourself: what it does, who it's for, how to start, in three lines.

OpenAI says GPT-6 Cyber patched 948 Linux kernel flaws

OpenAI announced GPT-6 Cyber: 48.5% on ExploitGym, against 32.1% for GPT-5.6 Cyber. According to OpenAI, an autonomous pipeline validated and patched 948 privilege-escalation flaws in the Linux kernel in one run, for about $1.2M of API, roughly $1,000 per flaw according to Greg Brockman. OpenAI researcher Eric Wallace says human researchers find about 20 such flaws a year.
