šµMulti-Model Wars, Shadow AI Reality, and the Rise of Voice Interfaces
October 2nd Edition 2025. ChatGPT Becomes an App Platform, Claude joins Copilot, shadow AI outperforms, and voice becomes core enterprise tech.

š Welcome
Welcome to this week's edition of the Business AI Newsletter.
Whatās Inside This Edition:
ChatGPT Becomes an App Platform & AgentKit Arrives
Microsoftās Bold AI Shift ā Anthropicās Claude joins Microsoft 365 Copilot, breaking OpenAIās monopoly.
Shadow AI vs. Enterprise ROI ā MIT reveals why 95% of corporate GenAI projects failāand how employees are quietly outperforming official pilots.
Voice Is the Next Keyboard ā Why AI-driven speech tech is crossing into business infrastructure and unlocking untapped data.
š ChatGPT Becomes an App Platform, and AgentKit Enters the Stage
OpenAI announced two major shifts that redefine how weāll use and build with AI:
š¢Apps Inside ChatGPT ā From Assistant to Platform

- Apps are now embedded directly in ChatGPT conversations, so you can interact with services without leaving chat.
- Early partners include Booking.com, Canva, Coursera, Expedia, Figma, Spotify, Zillow (with DoorDash, OpenTable, Target, Uber and more on the way).
- Developers get access to a preview SDK to start building apps, with an app directory and review process coming later.
- The result: seamless in-chat experiences where AI can surface the right tools in contextāwhether for booking, design, or search.
Availability: Rolling out globally now, with EU support coming soon.
šµ AgentKit ā Build Agents Without the Glue Work

Think of AgentKit as OpenAIās āall-in-one toolkitā for turning agent ideas into real, working systems. Instead of stitching tools together yourself, AgentKit provides:
- Visual Builder ā drag-and-drop workflow canvas for designing agent flows
- Built-in Integrations ā connect to data (via MCP), use ChatKit widgets, and tap into OpenAI models
- Configurable Guardrails ā set boundaries for safe, reliable behavior
- Logic & Data Components ā handle transformations and decisions inside the flow
- Templates ā jump-start with prebuilt patterns for common use cases
- Preview & Test Mode ā see how your agent behaves before going live
- One-Click Deployment ā push agents into production without custom plumbing
- Deep API Integration ā works seamlessly across OpenAIās ecosystem
Availability:
- ChatKit + new Evals ā General Availability
- Agent Builder ā Beta
- Connector Registry ā Rolling out in beta to API, Enterprise, Edu customers
Why It Matters?
Together, these launches transform ChatGPT into a platform for apps and agentsāblurring the line between conversation, action, and integration.
The opportunity for developers and businesses?
Build apps that meet users where they already are: in ChatGPT.
Deploy agents that are reliable enough for enterprise-grade workflows.
Microsoft just made a bold AI move: Embraces Anthropic's Claude
Microsoft just made a game-changing AI move: itās officially bringing Anthropicās Claude into Microsoft 365 Copilot.

Until now, Copilot was powered almost entirely by OpenAIās GPT models. Thatās over: enterprises now get a multi-model choice inside the same product experience.
Why it matters:
ā Enterprise Choice ā Pick Claude or GPT depending on the task
ā Performance Fit ā Claude shines at reasoning & structure; GPT at creativity
ā Multi-Platform ā Rolling gradually out across 365 Copilot, Copilot Studio, and Azure Databricks
ā ļø Admin Note ā Admins must explicitly opt-in for Anthropic in Microsoft 365 (Researcher Agent / Copilot Studio), and itās hosted outside Microsoft (on AWS)
Claudeās Meteoric Rise. The numbers tell a compelling story:
$183B valuation as of September 2025 (vs $61.5B in March 2025)
45% of API calls now come from enterprise platforms
30M+ monthly active users globally in Q2 2025 (40% YoY growth)
25B+ API calls per month as of June 2025
This isnāt just a Microsoft updateāitās the official start of the multi-model enterprise era.
š° From Shadow AI to Real ROI
MITās State of AI in Business 2025 Report just droppedāand the results are sobering:
95% of GenAI projects yield zero measurable ROI.
Only 5% of AI pilots deliver meaningful outcomes.
Employees using āShadow AIā tools independently are often outperforming official corporate initiatives.

The GenAI Divide ā Buyers (enterprises stuck in pilots) vs. Builders (AI-native startups scaling at speed).
Where the Money Really Is:
Operations & finance
Document processing automation
Cutting external agency spend
What Leaders Should Do Now:
Start distributed experimentationādonāt wait for perfect use cases
Learn from shadow AI patterns inside your workforce
Focus on back-office optimization (where ROI is emerging fastest)
Build adaptive systems with memory & learning baked in
Translation: Stop chasing shiny demos. Follow the workflows where employees are already winning with AI.
šļø Voice Is the Next Keyboard

Typing is optional. Speaking is inevitable.
The AI voice generator market is set to hit $20.4B by 2030, growing 37% annually (MarketsandMarkets). With speech-to-text hitting 95ā98% accuracy, voice AI is crossing from novelty to enterprise infrastructure.
Key Insights:
1. Voice AI bridges human + machine workflows / Friction Removal
šøField workers, doctors, and lawyers resist typing into systemsābut they'll talk to them. Voice interfaces dramatically lower the friction barrier to digital tool adoption across industries where keyboards are impractical or intrusive.
šøBusiness implication: Voice AI isn't just a featureāit's a change management strategy that drives adoption of digital workflows.
2. Conversations: Business's Richest Untapped Dataset
Most companies record calls but never analyze them systematically. Voice AI can surface actionable patterns:
šøWhy customers churn
šøWhat objections block sales
šøHow top performers communicate differently than average reps
Business implication: Leaders who mine conversations for insights outperform those who merely automate them.
3. Hybrid Sweet Spot:
Letting AI to handle the first 2ā3 simple, repetitive turns (FAQs, status checks), then seamlessly route complex issues to human agentsācapturing ~70% cost savings while freeing humans to focus on higher-value interactions.
Why This Matters for Business:
Voice = the most natural, hands-free interface
Unlocks new signals: tone, urgency, emotion
Expands digital adoption into industries where typing fails
Key Players:
Infrastructure: ElevenLabs, Deepgram, Retell AI
Enterprise Platforms: PolyAI, Twilio
š Whatās Next: The Agentic Web
MIT warns of a coming Agentic Webāautonomous AI agents transacting across the internet, unlocking an estimated $2.3T in latent labor value.
Final Thought
The future of business AI isnāt about a single model, tool, or feature. Itās about choice, adaptability, and learning from the bottom up.
If you found this useful, forward it to a colleague whoās also navigating the AI shift.
