Researcher uncovers 100,000+ phrases Apple blocks from iOS autocomplete

Researcher Derik Kauffman discovered a hidden list of over 100,000 words and phrases blocked from iOS autocomplete and swipe-typing across major languages, and published it online. The list includes slurs, sexual and drug terms, but also political phrases like 'dictator Trump,' 'sleepy Joe,' and 'covid was a hoax,' plus inconsistencies such as blocking 'bad girl' but not 'bad boy.' Kauffman extracted the list from a hash table buried in iOS using AI coding tools, and another researcher independently verified the findings; Apple told Reuters the keyboard avoids suggesting potentially offensive terms but doesn't stop users from typing them manually.

Simulation finds how high a 54-piece Jenga tower stands at various floor tilts

Using Codex and Claude Code to run simulated construction trials, an experiment determined the tallest stable Jenga tower achievable at floor tilts ranging from 0.1° to 25°. On a perfectly flat surface, all 54 blocks stood on end would reach 4.05 meters but collapse at just a 0.21° tilt; the AI-driven search instead found optimal heights for each tilt angle, ranging from 331.5 cm at 0.1° down to 19 cm at 25°.

New tool tmux-restore revives tmux sessions and AI agent chats after reboot

Developer Andrew Boldi released tmux-restore, an open-source tool that automatically saves tmux sessions, windows, panes, working directories and scrollback every minute and again at shutdown. It restores them on restart, and panes running coding agents like Claude Code, Codex, Gemini CLI, opencode or pi resume their exact prior conversations. The tool is installed via a shell script and builds on existing tmux-resurrect and tmux-continuum plugins.

Users report OpenAI's Codex silently re-enabled model training toggle

A developer reported that OpenAI's Codex tool had its 'Improve the model for everyone' data-sharing setting turned back on without their knowledge, despite having previously disabled it. Coworkers confirmed the same issue, and the poster noted the setting can be checked and disabled via OpenAI's data-controls and privacy pages. Other users on Hacker News had flagged similar behavior before.

deepsense.ai shares ten 'harness engineering' patterns for coding agents

deepsense.ai has published a playbook of ten patterns for structuring repositories and workflows around AI coding agents, developed after its team built HyperCode, a repository intelligence layer, during an OpenAI Codex hackathon. The patterns cover making repos agent-readable through documentation like AGENTS.md, compiling context just-in-time for tasks, and using validation loops to turn recurring agent mistakes into guardrails. The team tested these approaches internally across staff with varying experience using Codex and Claude Code.

Revolut switches ~2,000 engineers to self-hosted GLM for coding tasks

Revolut has migrated roughly 2,000 engineers to a self-hosted GLM model for coding, running it on 56 Nvidia B200 GPUs, according to David Abitbol, who leads AI operations at the company. Claude Code and Codex, previously the default tools from Anthropic and OpenAI, have been moved to an exception list, with Abitbol citing a blended cost of about 30 cents per million tokens, roughly a tenth of prior spend.

OpenAI sets January 2027 retirement date for ChatGPT Classic app

OpenAI is phasing out the original ChatGPT Classic desktop app, displaying a notice that it will be retired on January 30, 2027, with chat history carried over to the newer unified app. Separately, OpenAI is preparing to merge the Chat and Work tabs into one interface, consolidating their usage allowances.

OpenAI to merge ChatGPT's Chat and Work tabs in December

OpenAI announced it will combine ChatGPT's Chat and Work tabs into one unified interface starting in December, folding the agentic 'Work' capabilities into the main ChatGPT experience. The merged version will first roll out to select users for feedback before wider release, while Codex remains a separate tool within the desktop app.

OpenAI to merge ChatGPT's Chat and Work tabs

OpenAI is combining the Chat and Work tabs in its ChatGPT desktop app into a single interface, according to an email sent to select users for early feedback before wider rollout. The merged experience lets users move from idea exploration to task execution in one place, including building websites or presentations, while Codex remains separate. OpenAI also said ChatGPT and Codex will now share the same token allowance pool.

OpenAI to merge ChatGPT and Codex usage limits, test combined Chat-Work interface

OpenAI told subscribers by email that it will begin testing a unified Chat and Work experience in ChatGPT for a small group of users, letting them move from casual conversation to complex tasks like building websites or presentations without switching modes. The company is also merging usage allowances for ChatGPT and Codex into a single shared limit, though 'Unlimited Instant' conversations won't count against it, and Pro users have reportedly seen Work and Code usage limits doubled. Codex will stay separate within the desktop app for now.

OpenAI's GPT-5.6 Sol completes Factorio peaceful-mode run via Codex

Developer Ryan Madden reports that GPT-5.6 Sol, running in Codex with low thinking level, completed a peaceful (no-biters) Factorio playthrough through rocket launch in 13.5 hours of in-game time. Sol interacted with the game through a Python library that enforced the same GUI-style restrictions human players face, such as player reach and fog of war, and Madden tracked production statistics and science milestones throughout the run.

OpenAI doubles usage limits for ChatGPT Pro, Business Premium tiers after backlash

OpenAI announced it is doubling usage limits across its Pro 100, 200, and 500 tiers as well as Business Premium plans, effective immediately. The company said it will not cut usage limits for Pro 200 as previously planned, keeping Work and Codex usage unchanged, and will continue offering extended limits and separate usage tracking for its 'dots' feature.
