Yeah, it's a useful framework even with frontier. And it definitely lifts "cheap" frontier models like Haiku into more solid territory. I haven't done a ton of forge integrations into frontier (like pointing claude code into proxy mode) yet, but if you run into any issues let me know!
And we're off! It's working great with DeepSeek V4, although DeepSeek V4 Pro tends not to really run into problems anyway being near-frontier, but I definitely see improvement with Flash.
