To be honest, I am surprised by how good DeepSeek V4 Flash is. I use Claude Code and Codex on Claude 5 Opus and GPT-5.6 Sol most of the time, but when I use DS V4 Flash I don't feel like it's really that bad. And with oh-my-pi and just plain pi it's pretty good. To be honest the frontier models are much better at tool calling so in an assistant flow they're better but I did the dumb thing and optimized the harness for the model instead, rewriting the tools so they match what it guesses at, and DS V4 Flash does just fine.
The TTFT and tok/s are much higher on the small model so that makes it competitive for a bunch of things. It feels like what old Sonnet used to by the end of last year which is honestly damned good.
