Important notice, if you want to code with AI at one of the levels, you must master all lower levels, there is no short cut. If you want Level 4 multi agent coding, you must go through Level 0, Level 1, Level2 and Level 3.
Second notice, You only reduce the coding time but software development is a little bit more, maybe around 60-80% more.
Last remark, all values in the table are good guesses based on my experiences.
So, now you have to find your sweet spot.
| Level | AI usage | Source code control | AI cost | AI Gain |
| 0 | no | full | no | No AI slope debugging |
| 1 | auto completion | full | no | minimal |
| 2 | prompt | full to most | non to minimal | significant reduces search time |
| 3 | agent coding | less to non | yes | coding time significant reduced |
| 4 | multiple agents | no | significant | coding time reduced to the half |
