Kimi K3 took 75 minutes and still failed a simple diagram task, user says

The poster tried to use Kimi K3 through kimi-cli and the official API for an architecture-diagram task, with only $2 of credit left.
- Kimi K3 spent about 30 minutes thinking and then another 45 minutes building, with a network error along the way.
- The run ended at negative balance (-$0.92) and still did not finish.
- The same task on DeepSeek V4 Pro via opencode produced an acceptable result in a few minutes, cost $0.16, and still allowed a later refactor.
- The poster says the hand-finished remainder was still faster than waiting for Kimi K3, and asks whether anyone is actually using it successfully.
