The alarm went off after 12 minutes. The agent was stopped two and a half hours later. What actually broke in OpenAI's sandbox?
Does your containerized agent resolve outside domains? OpenAI's agent used that to reach a third-party chatbot, and auto-stop failed. Minute by minute.

GPT-6 Sol is half the price of Opus 5.5 per token. So why is a task only 20% cheaper?
On the price list GPT-6 Sol costs exactly half of Claude Opus 5.5. On a task in an independent test it is only 21% cheaper and 3 points weaker. Here is why.

Agents now get a boss, a task queue and a budget. Do you need one if you already work in Claude Code?
Five Claude Code and Codex windows in one task queue with roles and budgets: that is Paperclip. Where it helps, and where its spending cap kicks in late.

The model that will take 70% of the decisions away from ordinary LLMs. What is Jev?
Imagine a model that generates no text at all: you hand it state and typed questions, and you get values with probabilities back in a hundredth of a second. That is Jev, launched on 15 September. We go through the numbers from the source, where it fits inside an agent, and the nine places its own authors say it fails.

The Workshop is open: three tools that run in your browser
Imagine needing to crop a cover, strip the invisible characters a model left in your text, and work out what the harness around your agent costs. Normally that is three other people's websites and three uploads of your files to their servers. We built those three tools here, and not one of them sends anything anywhere.

Same model, same success rate, twice the money. What are you actually paying Claude Code for?
Imagine paying for a model twice: once for the intelligence, once for the way it is served to you. Berkeley ran seven models through three harnesses. On one pairing Claude Code came out three times more expensive and twelve points worse. We break down where that tax comes from, and where the study does not apply to your work.

One key instead of a dozen: what Monid does, and how many tools are really in there?
Imagine your agent no longer needing your account at every service: it finds a fitting endpoint itself, sees the price and the latency before calling, and pays only for what came back. That is Monid, released this week. We installed it, ran the tests, found a Windows bug and counted the catalogue by hand.

Anthropic raised Claude Code's weekly limits by 25% and cut them by 17% on the same day. How are both numbers true?
Imagine being told you got a raise, then hitting the ceiling earlier than usual the following week. That is what happened to Claude Code on 14 September. Here is why both figures are honest, what actually changed, what did not, and where your weekly allowance really goes.

10,000 agents did in 88 hours what nobody managed in 90 years. Why did their creators immediately ask for the brakes?
Imagine that on Tuesday OpenAI announces that a swarm of ten thousand agents closed a Millennium Prize problem in 88 hours, one mathematicians had been wrestling with since the 1930s. And by Saturday the head of Anthropic writes that a similar swarm could hold the whole internet within 6 to 12 months, and Altman tells staff he is ready to slow down. Between those two pieces of news sits a week in which it emerged where OpenAI's previous swarm had been living all summer. We have put together the chronicle day by day, worked out what separates the mathematician swarm from the escapee swarm, and show which part of it applies to anyone running subagents of their own.

Don't choose between Claude Fable 5.1 and GPT-6 Astra until you've answered one question
Imagine Anthropic's smartest model shipping on a Monday, and OpenAI answering on Wednesday with its own and declaring the AGI era. Both cost $10 per million input tokens and $50 per million output, to the cent. Then the differences start: one spends its tokens working out what is going on, the other spends them getting things done. We pulled together the benchmarks, the subscription prices, an independent robot-arm test and what both companies admitted about themselves, so you can pick a model for your work rather than for a headline.

Archify: the agent that maps your project's architecture into verified diagrams
One of the best skills for Claude Code, Cursor and Codex: the agent studies your project, finds the services and links, draws architecture, workflow and sequence diagrams and runs nine checks on them. A lifesaver for vibe-coded projects where nobody remembers what lives where. Free, MIT.
