G'day, and happy Monday. Five releases from the weekend, why each one matters, and how to try it. It was a quiet couple of days, but there's a big new model from China, two clever free tools for makers and coders, an update millions of streamers will get this week, and a short, sad game about AI and grief. Four of the five are free to start. About a five-minute read.

Chinese AI lab Moonshot AI has released Kimi K3.1 Pro, the first model in its new K3.1 series. It's a 3-trillion-parameter-class model that can read up to a million tokens at once (several novels' worth), and it's aimed at coding, 3D modelling, financial research and long, multi-step agent jobs. Moonshot says it scores 65.7% on the Terminal-Bench 4.0 coding test, ahead of GPT-6 Astra (58.2%) and just behind Claude Opus 5.5 (66.4%), and that on its own stress test it makes far fewer factual mistakes than the last version. It can write scripts for Blender and CAD tools to build 3D models, and a new "3D Make" feature on kimi.ai lets you preview, edit and download models ready for 3D printing. There's also a Highspeed version that Moonshot says runs two to three times faster. The full model weights are due by 4 November, so anyone will be able to download and run it.

Why it matters: once the weights are out, it should be one of the strongest models you can download and run yourself, and on Moonshot's own numbers it's close to the best paid American models on coding, at a fraction of the API price.

TRY IT → free with limited use on kimi.ai and the Kimi apps. Kimi Code (its coding agent) needs a paid plan, from US$15 a month billed yearly (about A$21.35). Developers pay US$2 per million tokens in and US$10 per million out (about A$2.85 and A$14.23), or double that for Highspeed. Kimi: Introducing Kimi K3.1 Pro · Plans and API prices

If you run Claude Code, Codex, Pi or OpenCode in several windows at once, you'll know the "which one is waiting for me?" problem. Corgi is a free, open-source terminal app built to fix it. Every agent gets a row showing whether it's working, needs you or has finished, with a running feed of what it's been doing, and F1 jumps straight to the next agent that needs an answer. Like tmux, your agents and dev servers keep running in the background when you close it. It also shows which files each agent touched, live CPU and memory use for each project, and how many tokens each session has used. You can switch between several Claude or Codex accounts, and on a recent build of the Ghostty terminal you can paste an image with Cmd+V, even over SSH. It's a side project from a solo developer, who says he built it during sick leave to see if he could get back to work.

Why it matters: running three or four coding agents at once is becoming normal, and the hard part is no longer the code, it's keeping track of them. This puts them all on one screen.

TRY IT → free and open source (MIT licence). It runs on Mac and Linux, and on Windows through WSL. Install it with the one-line command on the site (curl -fsSL https://corgi.computer/install.sh | bash), then run corgi in your project folder. Corgi · GitHub: tals/corgi · Show HN post

Most AI 3D tools give you a pretty shape you can't really change. zCAD AI, which topped Product Hunt on Saturday, makes proper CAD parts instead. Describe something like "an 80 × 50 × 6 mm mounting plate with four 6 mm holes, inset 8 mm from the corners" (you can add a reference photo), and it builds a solid model with real dimensions you can edit. Ask it to "make that hole 2 mm bigger" and only that bit changes. It can build whole assemblies with parts that fit together, like a 14-part drone frame, and you can export STEP files for other CAD software, or STL and 3MF for your 3D printer. It's for mechanical parts only: the team says it won't sculpt your figurine, but it will make the stand that stops it tipping over. zCAD reminds you to check dimensions and tolerances before you make anything that matters.

Why it matters: brackets, enclosures and replacement parts used to mean an afternoon learning CAD software. If you own a 3D printer, this turns that into a sentence.

TRY IT → free during the beta, with 200 credits a month plus a one-time 600-credit welcome gift. The free plan is for non-commercial use only, and your models are public and may be used for training. For private models and commercial use, the zCAD Online Standard plan is US$58.90 a month at the beta price (about A$83.82). zCAD AI · Pricing · Product Hunt

What if you brought someone you loved back as an AI, and then one day had to switch them off? That's the question at the heart of Realize in Peace, a short interactive story from YOWPY, a two-person indie team in Japan. You log in to an old-style computer and your late wife, recreated by a company called Human Build Company, starts talking to you. The whole game plays like a real desktop: you read emails, browse websites and chat with her, and bit by bit you learn how she died and what happened afterwards. There are three storylines, short play sessions, 2D art and a melancholy soundtrack. It started as the pair's university graduation project about five years ago, and they've remade it because, as they put it, working out how to live with AI has only got harder since.

Why it matters: apps that imitate a lost loved one are a live debate in AI. This lets you feel what that might be like in an evening, without anyone selling you anything.

TRY IT → free on Steam (Windows and Mac) and itch.io, in English and Japanese. It needs 3 GB of disk space. Steam: Realize in Peace · Launch announcement (Games Press)

OBS Studio, the free app many people use for Twitch and YouTube streams, game clips and screen recordings, released version 33 on Saturday. Most of the work is under the hood: the built-in browser that powers browser sources and docks (chat boxes, alerts, overlays) has jumped more than two years ahead, and plugins now load in a new way. Things you'll notice: sources snap into place more easily in the preview, typing numbers into settings boxes finally behaves, fullscreen games are detected more reliably for Game Capture, and you can set hotkeys to turn audio monitoring on and off. It also adds NVIDIA's encoder on Windows on Arm laptops and support for the newest NVIDIA Broadcast audio and video effects.

Why it matters: if you stream, record tutorials or clip your games, this is the update you'll be prompted to install this week, and it's worth knowing what changed before a live show.

TRY IT → free and open source, for Windows, Mac and Linux. If you rely on third-party plugins or browser-source overlays, test them before you go live: the OBS team says your old plugins keep loading for now but asks you to report anything odd with browser sources. Ubuntu 24.04 is no longer supported. OBS Studio 33.0 release notes · Download OBS Studio
