OPEN SOURCE AI

Nvidia, Microsoft, Meta, OpenAI, and 30+ signatories published an open letter arguing that open-weight AI models are essential to American AI leadership. The letter draws battle lines that divide Silicon Valley.

Microsoft's PHI-4 is an MIT-licensed 14 billion parameter model that matches Llama 3.3 70B and Qwen 2.5 72B on key benchmarks. Here is what makes it special, how to run it locally, and why small language models are increasingly practical for real development work.

Meta surprised the AI community with Llama 3.3, a 70 billion parameter model that delivers 405B-class performance at a fraction of the cost. Here is what the benchmarks show, where to run it, and why this release matters for developers building with open-source models.
