It’s interesting how almost every model released in 2025 has specifically targeting coding. That focus has clearly been paying off: these coding models are getting really good now.

I still contend that this sort of task is uniquely positioned to show off LLMs. The idea that they'll turn into agents that can do real-world tasks remains a fantasy. Despite how impressive this is, they're losing money and have no real path to profitability.

Look up Ed Zitron's newsletter and podcast for more info on why the industry is a bubble. I'm genuinely impressed with this specific example, but our economy is gonna suffer when the bubble bursts.
