Anthropic found that even frontier models fail 4 specific ways when you let them work longer than 5 minutes. I hit all of them before I figured out the fix. Not in theory. In practice. I had an agent that was supposed to build a working authentication module over a weekend. By …
OpenCode hit 160K GitHub stars and dethroned Cursor as the #1 AI dev tool. Claude Fable 5 launched with record benchmarks — then got suspended 3 days later. Here's what actually matters for your workflow.

Swapped between three AI models mid-task and learned which one handles structure vs. polish. 1,500 lines of CSS, 3 commits, one afternoon.
