I've been having an amazing time using v4. I started out with pro and it genuinely feels like a perfectly capable frontier model. I spent 50 cents for an hour of very heavy use.
Then I decided to checkout flash for the speed gains. I'm speechless. When setting the thinking to max, it feels extremely capable and it's lighting fast. But that's table stakes at this point. What blew my mind is that it cost me only 5 CENTS for 4 whole hours of heavy heavy use that incorporated intensive subagent loops.
I'm genuinely not understanding the lack of market reaction happening right now. My theory is that people feel like they overreacted to R1 and now they're less jumpy. But I'm left wondering how a trillion dollar industry is gonna justify such premiums when you can let it rip on like a cent an hour with an open source harness like opencode.
Edit: Also, I'm on opencode go, so I'm not even getting the massive deepseek discount.
