OpenAI launches o3 and new o4-mini
Better than Gemini?
OpenAI has released two new models as competition with Google’s Gemini intensifies. The models — o3 and o4-mini — are designed to improve performance in math, logic, coding, and visual understanding. O3 is positioned as OpenAI’s most advanced reasoning model yet, while o4-mini is optimized for faster, cheaper inference, targeting lighter workloads and competing directly with Gemini 1.5. Can OpenAI reassert itself as the clear frontrunner?

You’ve heard the hype. Now it’s time for results
After two years of siloed experiments, proofs of concept that fail to scale, and disappointing ROI, most enterprises are stuck. AI isn't transforming their organizations — it’s adding complexity, friction, and frustration.
But Writer customers are seeing a positive impact across their companies. Our end-to-end approach is delivering adoption and ROI at scale. Now, we’re applying that same platform and technology to bring agentic AI to the enterprise.
This isn’t just another hype train that doesn’t deliver. The AI you were promised is finally here — and it’s going to change the way enterprises operate.
See real agentic workflows in action, hear success stories from our beta testers, and learn how to align your IT and business teams.
OpenAI could acquire Codeium for $3 billion
Codeium
OpenAI is acquiring Codeium, now rebranded as Windsurf, in a deal valued at approximately $3 billion. Windsurf is an AI-powered coding assistant that offers real-time code suggestions and supports a wide range of programming languages, with a focus on Git integration. The tool is designed to improve code writing and debugging efficiency.
Following the acquisition, OpenAI is expected to incorporate Windsurf's technology into its existing suite of developer tools. This will likely enhance products such as the ChatGPT code interpreter and further develop OpenAI's competitive offerings in the AI-assisted coding space, including potential improvements to tools like GitHub Copilot.
