Google’s "Nano Banana" image editing model has gone viral, pushing the Gemini app to the top of the app store charts. In the US, Canada, the UK, and Germany, Google Gemini now holds the number one spot, ahead of ChatGPT at number two.

According to Google, Gemini reached nearly 450 million monthly active users in July, a number that has likely increased since then. During this time, the "Nano Banana" model, also known as "Gemini 2.5 Flash Image Generation," was used more than 500 million times.
OpenAI plans to give Microsoft a much smaller share of its revenue going forward, according to a report from The Information.
The company has reportedly told some investors that Microsoft's cut — currently just under 20 percent — will drop to around 8 percent by 2030. That shift would let OpenAI hold on to more than $50 billion in additional revenue to cover its massive computing costs. Under the original deal, Microsoft was guaranteed 20 percent through 2030.
In return, sources told The Information that Microsoft will get one-third of the restructured OpenAI entity, with another portion going to the nonprofit side. Microsoft still will not have a board seat. The two companies are also said to be negotiating over server expenses and contract terms around the potential use of artificial general intelligence (AGI).
Robby Walker, one of Apple's top AI executives, will leave the company next month, according to Bloomberg. Walker led Siri until earlier this year, when responsibility for the product shifted to software chief Craig Federighi. After that, he oversaw projects for a new AI-powered web search expected to launch in 2026, aimed at competing with services like ChatGPT and Perplexity. Most recently, he led Apple's "Answers, Information and Knowledge" team. His exit adds to a string of departures from Apple's AI division, including Ruoming Pang and Frank Chu, who left for Meta.
Nvidia is pulling back from direct competition with cloud providers like Amazon Web Services, according to The Information. Its GPU cloud service, DGX Cloud, will now be used mainly for Nvidia's own research. The service was originally pitched to banks, pharmaceutical companies, and other enterprises as a way to book computing power directly from Nvidia. But insiders say demand stayed low, partly because prices were higher than those of traditional cloud providers. Nvidia invested around $13 billion to rent back its own chips from AWS and other major clouds, then resold some of that capacity to customers like Amgen and ServiceNow. Publicly, Nvidia denies any shift in strategy. Company executive Alexis Black Bjorlin said DGX Cloud is fully booked and will continue to expand. At the same time, Nvidia has launched DGX Cloud Lepton, a marketplace where cloud providers can offer their own GPU resources.
OpenAI has rolled out a new "Developer Mode" for ChatGPT, giving Plus and Pro users on the web full access to MCP (Model Context Protocol) tools, including both read and write functions.
The beta feature lets developers connect their own remote servers, manage tools, and use them directly in chats. It supports OAuth authentication, HTTP streaming, and Server-Sent Events (SSE). To activate it, go to "Settings → Connectors → Advanced Settings → Developer Mode." Once enabled, you can add connectors directly through the chat input field.
OpenAI warns that Developer Mode comes with serious risks, including prompt injection, unintended write operations, and potentially dangerous tool execution. If an MCP server is compromised, it could access or alter user data. Any write action requires separate confirmation to proceed.
"It's powerful but dangerous, and is intended for developers who understand how to safely configure and test connectors."
AI startup Thinking Machines wants to make large language models more predictable. The team is studying why large language models sometimes give different answers to the same question, even when temperature is set to 0, a setting that should always return the most probable answer.

According to Thinking Machines, the problem isn't just GPU precision, which they say is "not entirely wrong" but "doesn’t reveal the full picture." Server load also affects how a model responds: when the system is under heavy load, the same model can produce slightly different results. To fix this, the team developed a custom inference method that keeps outputs consistent regardless of system load. More predictable behavior like this could make AI-supported research more reliable.
Adobe is bringing Google's new image AI, known as "Nano Banana" (officially Gemini 2.5 Flash Image), to Photoshop as an optional tool. The model is designed for editing existing images with a high level of consistency and reliability. Adobe's first demo video shows how Nano Banana works with the "Generative Fill" feature to expand or modify image content. The model is expected to roll out in September.
While Adobe's own Firefly image models support similar features, they don't reach the same level of quality. And if anyone from Adobe is reading: as a publisher, I'm no stranger to losing revenue to Big Tech. Feel free to reach out if you have questions.
