Introducing Claude Opus 5. It's a thoughtful and proactive model that comes close to the frontier intelligence of Fable 5 at half the price.

Tried recreating Fall Guys using the exact same prompt with Claude Opus 5.0 (Claude Code) and Kimi K3 (Kimi CLI). Kimi K3 nailed the gameplay out of the box. Physics, movement, and the overall feel were surprisingly solid Opus 5.0 had a shinier UI, but movement was broken, it kept adding unnecessary visual effects, lagged during gameplay, and spent most of its time reiterating instead of converging Runtime and cost : - Kimi K3: ~9 min, ~$4.4 - Opus 5.0: ~17 min (still iterating), ~$13+ That's roughly 2× the time and 3× the cost, yet Kimi produced the more playable result with the exact same prompt.

We removed ~80% of the Claude Code system prompt for our newest models, this is what we've learned about writing system prompts, skills and Claude.MDs for them.

Lying on the bed and talking to ChatGPT Voice to do work in codex is pretty great. To do this well I think you have to remember the names of all your long running threads.

People of @pidotdev! Pi-Codex-Conversion has now been updated to fully support dictation and realtime voice thanks to amazing work from @OpenAI and @OpenAIDevs pi install npm:@howaboua/pi-codex-conversion 1. /codex voice dictation 2. Clanker will set it up for your devices. If your audio setup is weird and shows "device busy", ask the Clanka to figure it out. Then run /codex voice dictation again. Do NOT /reload until you run /codex voice dictation. (this should now have a better error message and the /command dance should be simpler. The routing issue cannot be avoided tho) 3. Clanka will tell you about the system prompt. More below. 4. Push To Talk Ctrl+alt+D to dictate. Ctrl+alt+space for realtime voice (toggle). /codex voice => change from PTT to toggle. It also tells you where the keybinds are. Change your preferred voice there as well. That's it, it just works. Hopefully. You can use it with any main agent model. There's an option to turn on only voice features and use on all models in /codex. Now about that ./pi/agent/REALTIME-SYSTEM-PROMPT.md - this is NOT your AGENTS.md and NOT your typical system prompt. This teaches the voice model how to communicate. You can tweak it, but do not overcook it. It does contain bits about personality - change those. Or add a section. Just don't alter too much or you'll end up submitting an issue. We don't want that. The extension supports per folder .pi/REALTIME-SYSTEM-PROMPT.md files (you have to create them). The folder-level one gets appended to the main one. Again, this is not about your coding style etc, so don't overload it. These markdown files are for PERSONALITY. Anyway, I've got one small issue to fix (stupid system messages with dictation mode, but none of you is here for dictation amirite?) (now fixed) Do NOT fire up realtime voice control for more than Pi instance, you've been warned xD Otherwise, happy clanking! Submit issues here: Also, yes I did try to record a video, but the agent output sounded far too low in the recording and due to how complicated my setup is, I am not redoing it rn xD

New in Hermes Agent: a credential firewall for Docker sandboxes. Your real keys never enter the sandbox. It runs on stand-in tokens, and a local proxy swaps in the real keys at the network boundary. Tokens from a compromised sandbox are useless elsewhere. > hermes egress setup

Your bank statements don’t need a trip to the cloud. Vikram Vaswani paired Goose with Docker Model Runner + Gemma to analyze personal finances entirely on his laptop. No API costs, no token counting, no financial data leaving the nest. 🔒🪿
