Adam Mosseri, Head of Instagram, still wasn't sure how people would use Instagram's TV app on Amazon Fire the day before the integration rolled out. The team knew they would get things wrong, but they were ready to learn and iterate quickly. Instagram is likely to change dramatically in the next few years. The platform plans to let users proactively shape content on their feeds in a way that will feel fundamentally different.

Apple's Foldable iPhone is rumored to have an aspect ratio similar to that of Apple's largest iPads when viewed in landscape mode. It is expected to arrive in the fall of 2026 along with the iPhone 18 Pro. A wider foldable could help distinguish the device from Android book-style foldables. Samsung is apparently planning to release its own foldable with a wide aspect ratio in Q3 2026 to compete with the foldable iPhone.

Laptop designs need to be upgraded to make running AI models locally possible. The average laptop is underpowered for large language models. The most obvious way to boost a PC's AI performance is to place a powerful NPU alongside the CPU. Another upgrade required for PCs to run AI models is a unified memory architecture that provides all system resources to the same pool of memory over a fast, interconnected memory bus.

Lazy eye, or amblyopia, can occur when one eye is deprived of vision early in life. The lack of input disrupts synapse formation in the brain's primary visual cortex, weakening vision in that eye. A new mouse study has found that briefly and reversibly anesthetizing the retina of an amblyopic eye for just a few days can restore the brain's visual responses to that eye. While it is clear that the treatment seems to reset the way the brain engages with specific neurons, scientists still haven't figured out exactly why this is happening.

2025 was the year of agents. The year saw huge developments with large language models and tool execution. Developers can now build a lot of their own tools rather than depending on services. However, this has surfaced some problems, like a lot more unreviewed AI slop in pull requests.

Vercel's AI SDK is the leading TypeScript toolkit for building AI applications. It provides a unified API that allows developers to integrate with any AI provider. The SDK enables developers to build everything from chatbots to complex background agents. Version 6 introduces agents, tool execution approval, DevTools, full MCP support, reranking, image editing, and more.

This post contains 12 predictions for 2026 from a venture capitalist. 2026 will be the year enterprises productionize AI. It will be a record year for liquidity, though AI budgets will receive scrutiny for the first time. Labs will stop competing on every frontier as Google distances itself from competitors. Cloudflare will become the gatekeeper for agentic payments.

Riley Walz is known for his many creative projects. He always has over 50 ideas in his backlog at any point, so there's always something for him to do. Walz only works on ideas he thinks are fun. If you reject your own ideas, the part of the brain that comes up with ideas is going to stop. Making your ideas a reality again and again is the only way to generate better ones over time. There's no such thing as an impossible idea.

The combination of Rising Expectations and the perception of Rising Requirements has left an entire generation defining 'success' as something almost no one achieves, while also treating 'success' as something one needs in order to start a family.

The deal will help address the near-insatiable demand for energy to power the AI expansion.

Larry Ellison has agreed to provide an irrevocable personal guarantee of $40.4 billion of the equity financing for the offer and any damages claims against Paramount.

Claude Code shipped native Language Server Protocol support last week, enabling the IDE to actually understand code.

The instability in address/reputation pairing has implications for how well security threat mitigation services can perform.

Singapore-based AI firm Megaspeed has evolved into the single largest Southeast Asian buyer of Nvidia's chips in less than three years.
