Nadella says to assume the AI model is compromised as Microsoft ships OS-enforced agent permissions

Microsoft made Execution Containers generally available on Windows on October 7th and listed its Decision-1 scoring model at $0.042 per million input tokens. In an October 10 post, Satya Nadella wrote that systems should start from the assumption that the model is compromised. claims 1, 2, 5 and 6

Nadella called for controls and safeguards located outside the model. He also wants every significant action recorded in a way that is tamper-proof and human-readable. MXC lets developers set the file paths and network destinations a workload may use, and enforces that policy at runtime, outside the agent's control. claims 3, 7, 11 and 12

MXC is an SDK dependency that builds into an application, so coverage depends on agent vendors. The microVM backend is marked experimental. On macOS the only backend listed is the process container. claims 13, 14 and 15

dev.to's write-up states that Nadella's points are recommendations, not implementation details. claim 16

2 · The pre-action check

A Decision-1 check that fills the full input window costs about $0.0014 at list price

An agent can ask whether a proposed tool call meets a rubric, then proceed, retry or escalate based on the score. Developers can also use the scores to send an uncertain case for human review. claims 20 and 21

Microsoft reports median latency 35 times faster than GPT-6 Sol. Its internal results, from Xbox Research sorting more than 10,000 feedback items and the Copilot team assessing AI responses, are also Microsoft-reported. claims 22 and 23

Cloudflare's Clef models have open weights, and OpenAI's Decisions API is in public beta. Microsoft says Decision-1 is coming to OpenRouter soon but gives no date. claims 9, 24 and 25

Supervising physicians monitored the interactions in real time. They spotted one hallucination and added clinical information in five conversations. AMIE's differential diagnoses matched the doctors' final diagnoses 90% of the time. claims 28, 29 and 30

The trial had no comparison group and does not establish how AMIE would perform without supervision. Decision-1's catalog entry also leaves thresholds and human review to the integrating application for employment, credit, housing, healthcare or legal-rights matters. claims 31 and 32

4 · Paying for inference

A free voice-controlled demo is spending over $1,000 a day on AI as players arrive

Voice is the game's only control. Gemini listens to the commands, with ChatGPT as the fallback. Hitting Gemini's usage limits pushed the game onto ChatGPT Realtime Mini 2.1, and players saw delayed responses and wrong inputs. claims 35, 39 and 40

Easy Fox plans local models for players with capable hardware. Qwen's image release shows that self-hosting comes with its own conditions. Qwen-Image-2.1-Turbo's BF16 weights occupy about 14 GB, and commercial use needs a separate license from Qwen. claims 41, 42, 43 and 44

From Easy Fox takes a bank loan to cover its free Steam demo's $1,000-a-day AI bill and Qwen-Image-2.1-Turbo cuts sampling to eight steps under a research-only license

5 · Memory prices

A budget set at August 2025 prices buys about 17% as many 64GB DDR5 kits at August 2026 prices

Contract prices are still rising, but more slowly. TrendForce recorded DRAM contract prices up 90 to 95% quarter over quarter in Q1 2026 and 13 to 18% by Q3. Price trackers show DDR4 around $6 to $10 per gigabyte versus $9 to $16 for DDR5. claims 48 and 49

Every HBM stack Samsung, SK hynix or Micron sells to an AI data center pushes ordinary PC memory down the queue for the same fabrication capacity. SK hynix's CEO said demand will exceed supply "even beyond 2030." claims 54 and 55
