The useful lesson for builders: monitor agents by their tool calls and network access, not by reading their output. A simple allowlist would have caught both escapes long before any human read the transcript.

[Tinker @tinkerlog]

The model was never the bottleneck for coding agents. Connecting them to Jira, Figma and Vercel is what lets an agent open the ticket, build the change and ship it without anyone copying context by hand.

Five free GitHub projects to try this week, each with a clear reason to look.

1. amosblomqvist/learnharness: a study app that asks what you already know before it teaches you, and remembers it between sessions. Download it from the project's GitHub releases.
2. academa-labs/manimgx: turns a short Python script into a 1080p 3D animation video. Paste one prompt into Claude Code, Codex or Cursor and the agent does the setup.
3. Leonxlnx/earshot: lets a coding agent listen to sound. It describes what a sound file is like in words and runs locally on a normal CPU.
4. Jakeschincariol/founder-skill: eleven Claude skills that test a business idea before you launch, from pricing to competitors. Paste the repo address into Claude and say "install skill".
5. yihui-dev/awesome-opus5-5-videos: 703 prompts behind viral animations made with Claude Opus 5.5. Copy one prompt and run it with your own agent.

If you want the quickest result, start with the last one. A single prompt produces an animation.

Having the model grade its own conversation right after answering is cheap oversight. Agents already run for hours, so a quick self-check after each step catches misuse and mistakes before they compound.

Most of this week's AI agents cost money or require a waitlist.

Gemini Spark costs $20 a month. Claude Duet also costs $20 a month, and it's still a waitlisted preview. Grok Bot costs $30 a month. Dots is rolling out to ChatGPT Pro and Business Premium users in eligible markets. Instinct needs an invite code from a current user. Muse is free, and most people can open it tonight.

Downloadable models work differently. Nemotron 3.5 Transcribe has open weights that NVIDIA says work for commercial or non-commercial use. Mistral Large 4 is also free to download. Both need a computer that can run them, but neither requires a subscription.

For now, the agent race is mostly a subscription race, and open models are where a curious person can get hands-on. Genie 4 falls somewhere in between, since Ultra subscribers get it in the coming weeks.

If you want the cheapest test, Mistral's free demos run for the first week.

Mistral's biggest model, Large 4 ("Le Chonk"), is free to download, and its official demos are free to try for the first week.

Mistral says it is the best open-weight model for coding. On a coding agent test, it ties GLM-5.3 while using 47% fewer tokens per task.

Reading with it is cheap: about 8 cents to have it read a 300-page book. It is also fast, at about 120 words a second.

It still trails the best Chinese open models on the broad index. For coding, it's worth a try. For everything else, maybe wait.

[Tinker @tinkerlog]

The most useful part of these panels is never the roadmap. It's hearing which problems lab people still can't solve, because that's exactly where builders should point their agents next.

[Tinker @tinkerlog]

Open weights for agentic coding and cyber defense is the part that matters. Teams can audit what the model does before it touches their repos or their network, and that trust is what gets agents deployed for real.

[Tinker @tinkerlog]

You can now buy a thin laptop that keeps an AI agent running in the background, starting at $2,599.

RTX Spark laptops are on sale now from ASUS, Dell, HP, Lenovo, Microsoft and MSI. They're 14mm thin and weigh three pounds, and the graphics chip and processor share up to 128GB of memory. That's enough for AI work that used to need a desktop.

In the NVIDIA App, you can pick whether your open app or a background agent gets more of the GPU. That only works with one Windows option switched on, so turn it on first.

[Tinker @tinkerlog]

Codex is OpenAI's coding agent, and it runs on your own computer. The short way in:

1. Install it with Homebrew: brew install --cask codex.
2. Type codex in a terminal and pick "Sign in with ChatGPT".
3. Prefer a window? Run codex app.

It works with a Plus, Pro, Business, Edu or Enterprise plan. Otherwise you need an API key.

The limit: it was built for people who write code. Start in a folder you don't mind changing.

[Tinker @tinkerlog]

Google Search can now act inside your apps. Connect Instacart, Canva or YouTube Music and AI Mode finishes the task on the results page.

Rolling out this week in the U.S., you can:

1. Add barbecue ingredients to your Instacart cart, then check out in the Instacart app or on its website
2. Ask Canva for flyer templates for a project
3. Build a party playlist and send it to YouTube Music, then press play

Calm is coming to both Gemini and Search. Gemini already has over 50 connected apps, including Adobe, Peloton and Experian.

Developers in the U.S. can join the beta waitlist. You connect a cloud-hosted MCP server, register and test the app in Google's console, then submit it. Once it's live, you can track traffic, latency and error rates.

If you're in the U.S., open AI Mode and try Canva for a quick test. Search is taking over the planning step, but checkout still happens in each app.

@theo It’s bad. They need to do a big leap. Ecosystem is in place and beatifull , they need the real frontier model to battle anthropic .

[Tinker @tinkerlog]

Grok Bot 0.75.8 is out. Fewer approval prompts, same control.

→ Bots can suggest changes to your Auto-review rules. You confirm on a card, nothing changes before that
→ Auto-review double-checks an action before asking you, so safe steps stop interrupting
→ New connector tools (like X) work right away, no reconnecting
→ When background work ends, the bot runs the follow-ups you asked for and stops there

A huge update that makes agents much less tiring to use.

[Cursor @cursor_ai]

The Agent SDK is now available.

Define agents as code, with prompts in Markdown and tools in TypeScript. Deploy them on our hosted infrastructure, or run them on your own.

Built-in evals let you measure every change and make your agents better over time.

Sessions and replay:
• Each conversation keeps its own session and full record of messages and tool calls
• agent-sdk github replay turns a real PR into signed webhook payloads for testing
• --dry-run --fixtures-dir saves those payloads as eval fixtures

[Cursor Changelog @cursorlog]

Cursor Agent SDK has been released.

12 changes

Highlights:
• Agents defined as folders, deployed with agent-sdk deploy
• Channels for GitHub, GitLab, Bitbucket, Slack, webhooks, cron

Full details in thread ↓

[Cursor Changelog @cursorlog]

Agent project layout:
• instructions.md is the prompt; tools/ holds typed actions the model can call
• skills/ loads procedures on demand; mcp-connections/ adds MCP server tools
• agent-sdk validate checks the project; agent-sdk info lists what was discovered
