Key Developments & Data
Microsoft just deployed MAI-Transcribe-2-Streaming, a new AI model that continuously processes human speech via WebSocket before the speaker finishes talking.
The streaming variant is priced at $0.54 per audio hour and delivers initial transcript hypotheses within 320 milliseconds, supporting over 60 languages.
The company also released two text-to-speech models—MAI-Voice-2.1 and a faster Flash variant—costing $22 and $15 per million characters respectively.
The rollout fulfills a mandate from AI Chief Mustafa Suleyman to double down on internal MAI models to power Copilot agents natively across Excel and Outlook.
"We pay a lot of money to Anthropic, so our goal is to reduce and ultimately eliminate that cost." — Mustafa Suleyman

Zubiqo Strategic Assessment
Primary Impact
Developers building conversational AI agents and competing frontier model providers like OpenAI and Anthropic who face losing their biggest enterprise customer.
Strategic Shift
The transition from relying on external, generalized frontier models to in-house, specialized micro-models to control the raw unit economics of voice AI.
The Ripple Effect
Anthropic and OpenAI will likely face severe revenue compression from Microsoft within 12 months as Copilot workloads silently migrate to the proprietary MAI stack.
