🚨 Ex-OpenAI CTO Just Launched a New AI Platform

AI took a turn toward personalization this week.

Mira Murati, OpenAI’s former CTO, is back with Tinker — a new platform that lets anyone fine-tune and own their own models.

Perplexity released Comet, a fully AI-powered browser now open to the world that blends search, chat, and intelligence into one experience.

OpenAI quietly bought Roi, an AI finance app built to personalize ChatGPT and bring “memory” to money. And Elon Musk is building Grokipedia, a bold attempt to rebuild Wikipedia through xAI’s lens.

Let’s get into it.

”I believe AI has the potential to democratize creativity on an unprecedented scale. AI tools could lower the barriers and allow anyone with an idea to create.”

^{– Mira Murati, Former CTO of OpenAI}

📈 5 Must-Know AI Tools

Glambase – Build your own AI influencer. Customize their look, generate content, and earn money from fans.

MagicPath AI – Turn ideas into full brands, landing pages, or online courses with one prompt. Instantly generate UI, decks, and launch-ready assets.

n8n – Build no-code automations that actually scale. From content workflows to complex backend logic, n8n connects 500+ apps to automate anything you dream up.

MindStudio – Launch your own AI agent or assistant without touching code. Drag, drop, and deploy AI apps powered by OpenAI, Claude, or Gemini—all from one sleek builder.

ElevenLabs – Clone your voice, narrate scripts, or generate lifelike dialogue in 30+ languages. Perfect for creators, devs, and anyone needing pro-grade AI voices

Ex-OpenAI CTO Launches Tinker — An Open Platform for Fine-Tuning AI

Mira Murati — the former CTO behind ChatGPT and DALL·E — has launched Thinking Machines Lab, debuting its first product: Tinker, a fine-tuning platform that lets developers shape foundation models like LLaMA 3 or Qwen without closed APIs or heavy compute.

Built for openness and control, Tinker brings enterprise-grade customization to individual creators, startups, and research teams that want to own their models end-to-end.

🧩 What It Does

• Open-weight models: Train, download, and deploy anywhere.

• No infrastructure hassle: Compute and scaling handled automatically.

• Multiple modes: Supports supervised fine-tuning and RLHF.

• Transparent results: Includes experiment tracking and checkpoints.

• Free beta: Available now; usage pricing rolls out later this year.

⚙️ How It Works

Upload data → choose a base model → define goals like tone, accuracy, or domain expertise.
Tinker handles optimization and returns a tuned model ready for API use or self-hosting.

It sits between Hugging Face and OpenAI Fine-Tuning — but with a stronger focus on autonomy. You don’t just access a model; you own the one you train.

💡 Why It Matters: As big labs tighten control, Tinker re-opens the field — giving builders the tools to modify and deploy their own models responsibly. It shifts AI creation from closed platforms to open participation, empowering teams of any size to innovate on their own terms.

Perplexity’s Comet Browser — The Internet, Rewritten

Perplexity has officially released Comet, its AI-powered browser now available to everyone worldwide — for free. Initially invite-only, Comet became the year’s most in-demand AI product, blending real-time search, assistant integration, and distraction-free design into one seamless browsing experience.

At its core, Comet is built around a single idea: the internet should answer questions, not sell products. It reimagines browsing as a space for curiosity and productivity — not click funnels.

🚀 What’s New

• Comet Browser now public: free download for all users.

• Built-in Comet Assistant: an AI that browses with you — handling research, writing, coding, and e-commerce tasks in real time.

• Background Assistants: autonomous AIs that work across tabs or apps while you focus elsewhere.

• Email Assistant: cc it on any thread to auto-schedule, draft replies, and summarize inboxes.

• Mobile preview incoming: Comet’s AI interface coming soon to phones with voice-native control.

💡 What You Can Use It For

• Research smarter: browse sources, summarize, and save answers without switching tabs.

• Boost workflow: draft emails, plan tasks, and manage documents directly in-browser.

• Shop efficiently: ask for recommendations or alternatives instantly as you browse.

• Declutter the web: block noise, ads, and clickbait — focus purely on content.

Comet isn’t just a browser. It’s a statement about where the internet is heading. At a time when most platforms compete for clicks, Comet recenters the web around questions, knowledge, and curiosity. It blends the utility of an AI assistant with the openness of a browser, creating a space where asking and learning happen side by side. In short, Comet isn’t trying to replace the internet. It’s trying to fix it.

OpenAI Buys Roi to Power Its Personal AI Push

OpenAI quietly acquired Roi, a New York-based personal-finance startup that used AI to track users’ portfolios across stocks, crypto, and real estate. Roi will shut down on October 15 and delete all user data. Only its CEO Sujith Vishwajith is joining OpenAI.

It’s the latest in a string of small acqui-hires—including Context.ai, Crossing Minds, and Alex—showing how OpenAI is collecting teams that already know how to make AI feel human, adaptive, and personal.

🧩 What Roi Built

Founded in 2022 and backed by Balaji Srinivasan, Spark Capital, and Google’s Gradient Ventures, Roi unified a user’s entire financial footprint—stocks, crypto, DeFi, NFTs—into one conversational dashboard.

Users could even define how they wanted the AI to talk. One sample prompt read:

🔍 Why OpenAI Cares

Roi’s approach fits perfectly with OpenAI’s expanding consumer apps division, led by former Instacart CEO Fidji Simo. That team already owns products like:

• Pulse – personalized daily news digests

• Sora – a TikTok-style app of AI-generated video content

• Instant Checkout – shop directly inside ChatGPT

Roi’s personalization tech and its founder’s Airbnb-honed product instincts could strengthen these apps’ ability to learn tone, style, and preference—core ingredients of ChatGPT’s coming personal agent era.

💡 Why It Matters

This isn’t a finance play, but it’s personalization as infrastructure. Roi’s idea that software should evolve with you mirrors where OpenAI is heading: AI that remembers, adapts, and builds context over time. Each small acqui-hire adds a missing piece to that puzzle. The takeaway: OpenAI isn’t buying apps, it’s buying people who know how to make AI feel like yours.

Grokipedia: Musk’s AI Rival to Wikipedia

Elon Musk’s xAI is building Grokipedia, an AI-powered encyclopedia designed to rival Wikipedia and “fix” what Musk calls its bias. The project is positioned as a new foundation for online knowledge, powered by Grok’s language model and Musk’s broader plan to make X the center of both news and search. Grokipedia is live in early form and framed as a “massive improvement” that aims to reimagine how information is created and trusted.

The pitch is bold but risky. Wikipedia has two decades of community editing, transparency, and verification behind it. Grokipedia will need to prove it can avoid both misinformation and algorithmic bias while earning public trust. Musk’s history of shaping discourse on X makes this launch more than another AI product—it’s a direct attempt to redefine who writes and owns the internet’s source of truth.
