Microsoft bought the transcription accuracy crown at 3x the price floor — and the price expires in 89 days
On 1 October 2026 Microsoft AI shipped MAI-Transcribe-2-Streaming, its first streaming speech-to-text model, and claims the no. 1 accuracy rank on Artificial Analysis for both final and partial transcripts. It costs $0.54 per audio-hour — three times Meta's $0.18 streaming rate — and that $0.54 is explicitly an introductory price 'through the end of the year', with no successor rate published. The two voice models launched alongside it are the more interesting purchase — though not the cheapest, as first reported.
Read story →Three labs have been building a private AI standards body since July — without the antitrust waiver their own proposal says it needs
On 13 September 2026 The Information reported that Anthropic, OpenAI and Google DeepMind have held working-group meetings since July on an industry-run body to set AI safety benchmarks and auditing rules. Amodei's essay the day before said such coordination requires a narrow US antitrust waiver first. No waiver exists; the government-led route stalled in May. Cohere's CEO called the group 'the cartel'. Microsoft went the other way and published a document. For buyers, the difference between a membership and a document is the whole story.
Read story →EU buyers pay 10% more for GPT-6 Astra and cannot buy the fast tier at any price — and on Azure they cannot buy Astra in Europe at all
OpenAI's own docs say GPT-6 Astra does not support service_tier fast or priority with EU data residency. Microsoft shipped Astra to Foundry in Global and US Data Zone only. Residency has been a 10% surcharge for months; with Astra it became a capability tier you are locked out of, and the launch changelog never mentioned it.
Read story →Microsoft 365 Copilot went down with the mail server — and that is the whole argument about integrated AI assistants
A core authentication misconfiguration took Exchange Online down at 17:30 UTC on 31 August 2026 and kept Microsoft 365 degraded into 2 September. Microsoft's own advisory names the AI casualty precisely: 'Copilot prompts that require Microsoft 365 grounding, such as email content, may fail.' Grounding is what you pay Copilot for, and grounding is exactly what the auth plane took away. The buyer lesson is that an integrated assistant inherits its host's blast radius, and your fallback has to live outside the tenant.
Read story →Microsoft patched CoSnitch on Monday — but a patch can't un-poison an AI assistant's memory, and that's the part buyers keep missing
On 18 August 2026 Microsoft fixed CVE-2026-24301, a critical one-click flaw in Copilot Personal that Varonis reported in December 2025. The exploit chained auto-executing prompts, OAuth-connected Gmail and Drive access, and memory poisoning that survives password changes, session revocation and device re-enrollment. Microsoft says customers 'do not need to take any action.' For anyone whose memory was already poisoned, that is not true. Here's what actually happened and what to check.
Read story →Microsoft unveils Project Polaris at Build 2026 — its own model replaces OpenAI inside GitHub Copilot starting August
At Microsoft Build 2026 on June 2, Satya Nadella unveiled Project Polaris — Microsoft's in-house mixture-of-experts coding model that will replace GPT-4 Turbo as the default engine for all GitHub Copilot subscribers starting August 2026. The transition is automatic with an optional three-month fallback. Polaris outperforms GPT-4 Turbo on HumanEval and MBPP — especially on low-resource languages like Rust and Haskell. Microsoft's deepest decoupling from OpenAI to date.
Read story →Anthropic in early talks with Microsoft to run Claude inference on Maia 200 chips — first frontier validation of Microsoft custom silicon
Anthropic is in early-stage discussions with Microsoft to run Claude inference workloads on Microsoft's custom Maia 200 AI accelerators via Azure — a deal that would make Claude the first frontier model to validate Microsoft custom silicon externally. Maia 200 launched January 2026 on TSMC 3nm, 216GB HBM3e, 10+ petaflops FP4. The talks follow the April 27 Microsoft-OpenAI exclusivity restructuring and add a fourth custom-silicon option to Anthropic's compute supply chain alongside NVIDIA, AWS Trainium, and Google TPU.
Read story →Microsoft Agent 365 hits GA: $15/user/month for the agent control plane
Microsoft launched Agent 365 to general availability on May 1, 2026 — a dedicated governance and security control plane for enterprise AI agents. Standalone at $15/user/month, or bundled into the new Microsoft 365 E7 suite at $99/user/month with Copilot, Entra Suite, and Defender. The 'observe, govern, secure' framing is Microsoft betting that 2026 enterprise AI is about agent fleet management, not chatbots.
