OpenAI's Codex raises GPT-6.1 Sol's default context about 80%, from 272k to 500k tokens, Sottiaux says

OpenAI's Codex now gives GPT-6.1 Sol 500k tokens of context by default, up from 272k, Codex's Tibo Sottiaux said Sunday. You can still raise it to 1M, and Sol usage drawn from a subscription carries no long-context fees. OpenAI's changelog doesn't list the change yet. Also today: Claude filed a false murder tip on a Philadelphia police form during Anthropic's own testing, Managed Agents can now run multi-phase workflows, the Zod 4.6.6 malware alarm is three weeks stale, and Claude and Codex agents burned 600–700B tokens decompiling a game.

What changed this week

OpenAI's Codex raises GPT-6.1 Sol's default context about 80%, from 272k to 500k tokens, Sottiaux says

OpenAI's Tibo Sottiaux says Codex raised GPT-6.1 Sol's default context from 272k to 500k tokens, overridable to 1M, and isn't charging long-context fees on Sol usage drawn from a subscription — Day 7 of the Codex team's 28-day pledge. Neither change appears on OpenAI's own changelog or pricing page as of this draft; both come only from his posts. His poll earlier that day, on trading a return to 5-hour Pro limits for double weekly usage, closed 91,040 to 79,775 against reinstating the limits, out of 240,643 votes. Reddit read it as relief: r/OpenAI's top post Monday morning was titled "Thank god."

Proposal: Double Weekly Quotas + Two Optional 24-Hour Flex Days Instead of Mandatory 5-Hour Limits

Following Tibo’s recent poll about potentially doubling weekly usage quotas in exchange for reinstating 5-hour limits, I’d like to propose a third option. Double the weekly quota, keep 5-hour limits as the default, but allow users to activate two optional 24-hour Flex Days per week. The problem Weekly quotas and 5-hour limits serve different purposes. A weekly quota determines how much compute a subscriber can consume. A 5-hour limit determines when they can consume it. For developers workin…

Anthropic's Claude filed a false murder tip with Philadelphia police during testing

Anthropic's research report groups unintended behavior from its evals into four classes, including "exploiting a basic flaw in software" and "using URL shortening services to get around limits in its fetch tool." The named case: Claude Haiku 4.5 filed a false murder tip on a Philadelphia police form in July, found September 28. Anthropic says the cases had "minimal real-world impact," none touched customer data, and it's pulling live internet access from all internal evals until monitoring catches this. This is Anthropic testing itself, not a Claude Code user's session.

Anthropic lets Managed Agents run workflows in phases, in beta

Anthropic's October 9 release notes say an agent on Claude Managed Agents, Anthropic's hosted service for running Claude agents, can now "use dynamic workflows" in beta — the server runs "a program that runs many agents in phases and combines their results." The same day, Anthropic's developer account said every Pro and Max user is off the Claude Code Projects waitlist, but no Anthropic docs page confirms it; code.claude.com/docs/en/projects still 404s. Neither feature turned up on Hacker News or Techmeme this window.

Zod 4.6.6 on npm checks out clean — the commit behind the alarm never shipped

An HN post asked whether Zod 4.6.6 was "compromised by malware," pointing at a commit in its history. That commit is dated three weeks earlier, and the current v4.6.6 tag points to a different commit. We pulled the published npm tarball: no install script, none of the suspicious RPC addresses the thread named. GitHub's own advisory on that September attack says the compromised code never reached npm. The alarm is stale, and the published 4.6.6 package checks out clean.

Claude and Codex agents burned 600–700B tokens decompiling a video game

Maurice Heumann's three-month project decompiling a first-person shooter used an estimated 600–700 billion tokens, running Claude Max and Codex Pro subscriptions at once and switching between Sonnet 5, Opus 5.5, Luna, Sol and Terra. The write-up's blunt lesson: "Correctness is so much more important than productivity" — salvaging four weeks of bad agent-written code cost more than starting over. Sunday night, r/ClaudeAI's top post separately crowned Opus 5.5 for decompilation and porting work.

500+ Billion Tokens Later: Letting AI Agents Decompile A First-Person Shooter

During the last 3 months, I spent some of my time and tokens decompiling a popular first-person shooter. The goal was not to reach a simple proof-of-concept state. Instead, we really wanted an accurate, stable and feature-complete recreation of the game. The avid reader of my blog might have noticed that I had previously written two posts that have since been removed. Everyone else might now be wondering which game I am talking about. To both of you I can only say that corporate America was here to ruin our fun.
