The bot directory has a two button switch at the top left: Standard and PRO. It changes how the bot cards are presented, and it is saved against your WordPress user account, so each administrator on the site can set it independently and it survives page loads.
In Standard mode:
Every card shows a single Open button pointing at the normal version of that bot. The thirteen multi model bots additionally show a short line noting that PRO unlocks five models, so you can see what is behind the switch without flipping it.
In PRO mode:
The thirteen multi model bots grow a row of five small model links underneath the Open button: Gemini, ChatGPT, Claude, LLaMa and DeepSeek. Each one opens a version of that same bot built around that model, so you can send the same task to a different model without hunting for the right page in the members area. Each pill carries the model's own mark and a tooltip naming it in full. If a particular model version is ever missing for a bot, that pill falls back to the standard version of the bot rather than breaking.
The Open button never changes. It always points at the standard version of the bot, in both modes.
Which bots have model choice?
Only the thirteen carrying the PRO pill. The three premium bots and the seven standard bots have one version each and their cards look the same in both modes.
Does switching to PRO give me access?
No. The switch is a display preference inside your own WordPress admin. It reveals links, nothing more. Whether any given bot opens for you is decided by your Results With Kevin members account when you land on the page.
Which model should I pick?
There is no single right answer, which is exactly why the row exists. The practical approach is to run the same brief through two or three of them for an important piece, then keep using whichever one suits your voice. Star that bot so it sits at the top of the grid next time.
