quick question, what the fuck
Supposedly this does not work anymore since last Codex update. I overheard a prompt that may fix it, in the replies.
everyone thinks codex computer use only works inside codex
it doesn't, it's a local mcp server in the chatgpt mac app and claude code can just call it, even headless with claude -p
same 8-task test: opus 5.5 on codex's engine got 6/8, codex itself got 6/8, cua driver got 3-4/8 at 4x the cost
cua's background mode on mac only goes through accessibility, so canvases and drags just don't land
codex's engine sends real clicks and drags to the app without touching my cursor
no hover though, and it's unofficial, so enjoy it until a chatgpt update breaks it
give this to your claude:
"Set up Codex's computer use as an MCP server for you on my Mac. Find the "cua_repl" entry in ~/.codex/plugins/cache/openai-bundled/unified-computer-use/<newest version>/.mcp.json and register it as a user MCP server called "codex-cu" with the same command, args and env. Then test it by using Calculator in the background to work out 12 × 12."
Rename the helper .app so Spotlight can tell it apart. Copy the plugin's .mcp.json and repoint every ChatGPT.app and ~/.codex path, including require-browser-access.mjs. Set CODEX_HOME, CODEX_CLI_PATH, PATH, SKY_CUA_SERVICE_PATH and SKY_CUA_SERVICE_NATIVE_PIPE_PATH.
The Aliens edit each other now.
We asked GPT-6 Astra to edit Qwen3.5-0.8B weights to improve math.
It directly changed only 0.016% of weights, fixing 0.8B's reasoning loops & improving math up to 6x and even instruction following 3x, without gradients or training.
We call this Weight-Space Programming: frontier LLMs can now natively read/write neural network weights! 🧵

Readers added context they thought people might want to know
LLM was given weights explicitly as text in prompt and used code/forward passes (per authors' logs) to ablate Qwen looping direction, a known thinking-mode issue per model card. Primarily fixed repetition in that mode, not general 'natively' improving weights/math.

Slop everywhere! Prevent weird conflicts with AGENTS .md, and stay DRY:
"autoMemoryEnabled": false
Claude no longer reads or writes the memory folder.
"autoDreamEnabled": false
the background step that tidies memories is off as well.
in ~/.claude/settings.json
Claude Desktop's task list and wrap-up boxes confusing and in your way? Add to ~/.claude/CLAUDE.md:
"Don't use the task list (update_plan) or the wrap-up box (wrap_up). Reply in plain linear chat; ask questions in the message text."
Probably keeps context cleaner too 🙌
"A few vblanks" - good old times!
I had a similar reaction. Everyone should applaud performance improvements, but gauge against the “speed of light”, not just a sloppy competitor. If you are measuring in seconds, you may have already anchored yourself incorrectly.
Structure the UI so you can put locally cached media up just a few vblanks after the process launches.
Structure the server so it can return everything necessary for the dynamic UI in one single query that was kicked off in parallel with the Gfx API initialization, branching to a modern transport protocol for large media files.
You should be able to double click on the launcher and have it responsive before your muscle memory can slam the pointer to a location to click on.
. @steipete included the follow-claude-desktop feature into CodexBar, as per my tickets ❤️
I made a tiny macOS usage bar for Claude Desktop. It follows whichever account you're signed into, all accounts at a glance.
Couldn't find one that did this, so I built it:
github.com/flutterrausch/cla…
Not a single use case in the comments.
You better turn off this "lose context" thing.

Most usage trackers are built for Claude Code, not the desktop app. They don't follow its account switches, so they keep showing the old account.
Greetings to your clanker.
