On March 6, the global AI landscape shifted.
In today’s rapidly evolving AI landscape, two names stand out in the realm of conversational assistants—Anthropic’s Claude and OpenAI’s ChatGPT. Although both are built on large language models, they diverge sharply in design philosophy, technical implementation, safety protocols, and real‑world performance. This article examines their fundamental differences, reviews benchmark results, and outlines use case recommendations, providing a forward‑looking analysis for decision‑makers and developers alike.
The AI race just got more interesting.

Today, in the Calculated Risk Real Estate Newsletter: Final Look at Local Housing Markets in February and a Look Ahead to March Sales A brief excerpt: After the National Association of Realtors® (NAR) releases the monthly existing home sales report, I pick up additional local market data that is reported after the NAR. This is the final look at local markets in February. Tom Lawler’s estimate was very close (as usual). Sales averaged over 5.5 million SAAR for the month of February in the 2017-2020 period. So, sales were still about 23% below pre-pandemic levels. Here is a look at months-of-supply using NSA sales. Since this is NSA data, it is likely months-of-supply will increase into the Summer. There is much more in the article.

Sales of new single-family houses in February 2025 were at a seasonally adjusted annual rate of 676,000, according to estimates released jointly today by the U.S. Census Bureau and the Department of Housing and Urban Development.

New home sales were slightly below pre-pandemic levels. The months of supply decreased in February to 8.9 months from 9.0 months in January.

Sales were close to expectations of 680 thousand SAAR, however sales for the three previous months were revised down, combined. I'll have more later today.
