r/OpenSource just banned projects that use AI in any way. Built with AI help, AI-written code, AI tools: out. Violators get permanently banned.

Linus Torvalds himself is now writing kernel patches with help from Claude Code.

Is the Linux kernel banned now?

Running Claude through the Agents SDK? Your 5-hour limit drains faster than it should.

Theo confirmed it's a bug on Anthropic's side and reported it. Weekly limits are fine. Claude Code used directly isn't hit.

Check the harness before blaming the model.

Spent a lot of time on this today. I confirmed it's a real bug on Anthropic's side. To be clear: this does not affect weekly limits.

All Agents SDK usage will drain your 5h limits faster than using Claude Code directly.

I have reported this to Anthropic, hoping for a fix soon.

Quiet detail in Anthropic's help docs: Opus 5.5 falls back to Opus 5 on some frontier LLM work, like kernel development for certain ML accelerators.

My read: within a year, every top lab gates help on building rival models.

Fair safety call, or protecting the moat?

Hot take: vibe coding isn't the problem. Vibe shipping is.

Prompting your way to a prototype is fine. Merging code nobody read into production is how you get paged at 3 AM.

Where do you draw the line?

My read: Anthropic answers OpenAI's discounts before it lists. Cheaper Opus or bigger limits, by end of November.

Signals: Rippling's coding work went 57% Anthropic to 18%, Opus 5.5 users keep hitting limits, and the IPO is reportedly weeks away.

Price cut or limits bump first?

Codex or Claude Code. You only get one for the next 30 days.

Which one, and what's the one thing that decided it?

The PR had 1,200 lines, a clean description, and an approval from the AI reviewer.

The senior engineer approved it in four minutes.

Nine days later it took down checkout for two hours.

Nobody on the team had actually read it.

The ticket was simple: add retries to the payment client. A junior engineer, the fastest shipper on the team that quarter, asked the agent to do it. The agent did more. Refactored the client. Added a cache. Wrote 40 tests. All green.

The AI reviewer left three style comments. The agent fixed them. Approved.

The senior had 23 PRs in his queue that day. Great description. Tests passing. Bot approved. Merge.

What nobody noticed: the new logic also retried on timeouts. Under load, every slow payment call became three calls. Then nine. The provider started rate-limiting. Checkout died.

The postmortem got awkward fast. Who wrote the bug? The agent. Who approved it? A bot, and a human who trusted the bot. Who understood it? No one.

The fix was one line. Finding it took two hours, because nobody knew the code. The agent had already moved on to its next ticket.

Fiction. But if your team ships with agents, you've seen a version of it.

An approval should mean a human understood the change. If nobody did, it's not a review. It's a rubber stamp with extra steps.

So who takes the blame here: the junior, the senior, or the bot?

Prediction: Kimi K3.1 Pro's weights land Nov 4 as promised, and it's the best open model you can download.

Signals: it's already 4th on Artificial Analysis's Intelligence Index, ahead of every open model, at half Opus 5.5's price.

Self-host it or stick to the API?

inclusionAI released an open healthcare model, Ling-3.0-flash-Sante.

124B params, 5.1B active, 256K context. Weights on Hugging Face, free on Vercel's AI Gateway. Research only, not a medical device.

Hospitals can't ship patient data to an API. Open weights fix that.

17 new AI billionaires added $87B in the first nine months of 2026, reaching $221B combined, per the Bloomberg Billionaires Index.

Seven are Anthropic co-founders. Others include Yan Junjie of MiniMax and Liang Wenfeng of DeepSeek.

The real AI salary is the cap table.

The Bank for International Settlements checked who funds AI firms.

2021-2025: 55.2% of the money flowing into AI firms came from other AI firms. In 46.4% of AI-to-AI deal value, the two were also supplier and customer.

Part of the AI boom is financing its own customers.

Higgsfield says it crossed $1B in annualized revenue 18 months after launch. Nvidia and TCV just invested.

The stat that matters: its announcement puts generative video at $30 to $150 per million equivalent tokens. Text: $0.15 to $0.60.

Text is the loss leader. Pixels pay.

GPUs are still renting above a standard 6-year depreciation schedule, per a16z.

H200: +143%
B200: +111%
H100: +54%
A100: +9%

Most of the gap opened after April, when token demand took off.

The GPU glut people keep predicting isn't here.

Harvard pitted Claude Opus 4.8 against paid expert peer reviews of 124 papers, reviews authors rated highly.

Three former journal editors, blind, picked the AI review in 26 of 30 judgments.

Wrong claims: 5.5% for AI, 15.9% for humans.

Reviewer 2 has competition.

Ask Claude Opus 5.5 to reverse engineer a binary and you may not get Opus 5.5.

Exploit generation, binary vuln scanning and pentesting get rerouted to Opus 4.8. You get a notice and the chat stays on 4.8.

Verified security teams can't get 5.5 yet.

Read the model label.

When your coding agent fails, what do you blame first?

- The model
- The prompt
- The harness
- The codebase

Be honest. My bet: it's the codebase far more often than people admit.

There are now enough AI agents living in iMessage, WhatsApp and SMS that TechCrunch needed a list.

They book things, remember context and follow up without you opening an app.

The next big interface is the one you already check all day.

Would you text an agent?

Meta planned to shrink some teams by up to 60% and hand the work to AI agents.

Internally it was called Project OT.

Then Meta's own numbers started coming in.

Hours before a big round of layoffs, Zuckerberg called off planning for the next wave.

The idea, per a Reuters investigation: make Meta "AI native." Agents do much of the daily work. Smaller, "talent-dense" groups of humans oversee them.

The agents did produce. Code changes to internal platforms and infrastructure were up 220% year over year, according to a post by CTO Andrew Bosworth.

Changes that became new or upgraded features for users? Up 36%.

That was the good news.

Staff were angry too. Meta had installed tracking software to record their keystrokes and clicks to train its agents. Believing they might be training their own replacements, employees pushed back.

As early as March, infrastructure teams had flagged "reliability warning signs" from the AI coding surge. One internal post said unchecked agents were taking "large-scale, disruptive actions that humans are unlikely to execute."

Major technical and security incidents rose 40% from the year before. Time staff spent firefighting them rose 70%.

Meta confirmed Project OT exists. It says the 60% applied to scenarios for some teams, not the whole company.

My read: this doesn't prove agents don't work. It proves agents without people who deeply understand the system create mess faster than humans can clean it up.

Would you give an AI agent production access at your company?

Volkswagen Group put Copilot in front of 330,000+ employees.

Copilot Chat hit 300,000+ monthly users first. More than 26,000 agents were active across the Group last month.

Adoption is solved. Knowing what 26,000 agents are doing isn't.

The fired OpenAI safety researchers gave their first interview.

Tomek Korbak says OpenAI acted broadly in good faith, but METR's investigation was "quite restricted." His fix: auditors embedded like employees, with unrestricted access.

An audit on the lab's terms is a demo.
