Seriously. The pace of frontier model updates is insane. Most days I feel like I'm being punked.
According to Every, "It’s much faster than Opus 4.7, easier to collaborate with, better at writing than any OpenAI model we’ve used since GPT-4.5 and GPT-4o, and the strongest model we’ve tested on our new Senior Engineer Benchmark, which measures how well models can rewrite a slop-coded codebase the way a senior engineer would."
