Microsoft wants you to watch your own AI agents like insiders.

Guardian Agents vets every agent action before it runs, and risky ones wait for a human sign-off.

Microsoft's security chief says frontier models "cannot be trusted"; Defender just added 35 agent types, 60 total including Claude Code, per Microsoft. Read why Microsoft wants agent monitoring kept apart from the model vendor.

Also in today's brief

  • Microsoft calls your own AI agents a threat
  • Nvidia's new agent model skips the cloud entirely
  • fal's quality claim doesn't survive independent testing
  • AWS just picked a fight with Nvidia
  • One Sheets prompt can burn your BigQuery budget
 
New: Pondero Labs

This week we started something new. Pondero Labs puts AI tools through real jobs and publishes everything: the setup, the screenshots, the answer key and the raw results.

No vendor demos and no paid results. We write the answer key before we run a test, so you can check our grading or rerun it yourself.

The first five labs:

•Exa vs Tavily vs Firecrawl: the same searches through three search APIs built for AI agents, and which one won in our test.
•Lindy AI review: real jobs in Slack, web research and scheduled routines, with the cost of each task.
•Lindy in Slack: can an AI assistant find a fact buried deep in a long, busy channel?
•Can an AI agent price AI tools? In our test, every wrong answer fell into the same trap.
•How to set up a Lindy routine: a weekly pricing-change tracker, built step by step from a real setup.

See every test on the Pondero Labs page. Want a tool tested next? Reply to this email and tell us which one.

Models & Releases
Nvidia Nemotron 3.5 Super VL and Bolt illustration

Nvidia squeezes a 74B agent model into 24GB.

Nemotron 3.5 Super VL is a 120B open agent model, and its Bolt sibling packs 74B into 24GB for cloud-free agents, per Nvidia. See the regulated jobs Nvidia is aiming Bolt at.

 
fal FLUX 3 Max video model illustration

fal pitches FLUX 3 Max as 22x faster than Seedance 2.5.

fal claims about 12 seconds per 10-second clip versus 278 for Seedance 2.5; an independent leaderboard ranks its quality anywhere from first to fifth. Check the leaderboard math before you switch video models.

 
Tools & How-To
AWS TorchNeuron Trainium PyTorch illustration

AWS moves PyTorch onto Trainium with one config line.

TorchNeuron lets existing PyTorch code run on Trainium2 and Trainium3 after a single config change, per Amazon, a direct shot at Nvidia's CUDA moat. See why AWS's 70% Deepgram figure is narrower than it sounds.

 
From the Pondero Stack
Gemini in Google Sheets for BigQuery illustration

Gemini in Sheets now queries all of BigQuery.

Ask Gemini a question in Sheets and it queries your full BigQuery table, then pins a live dashboard tab that refreshes on schedule. See which plans qualify and the one scan that eats your free tier.
