The P.A.M. or Predictive Analytic Machine is a sophisticated AI located at the Railroad HQ in Fallout 4.

Background
The development of the Predictive Analytic Machine, abbreviated P.A.M., was a joint project between the Defense Intelligence Agency and the military to develop an advanced artificial intelligence program capable of accurately predicting hostilities. Wired to an assaultron body, the robot could be dismantled and relocated in the event of an enemy attack.

On January 28, 2077, P.A.M. predicted that there would be a 12% chance of the DEFCON level increasing within the month, stating that “In order to increase global stability a diverse set of detailed strategies must be adopted." It was not destroyed during the Great War, and was later found by members of the Railroad in the Switchboard. Railroad operatives reprogrammed P.A.M. to support Railroad initiatives, relocating it to the Railroad HQ below the Old North Church.

Other interactions

 * P.A.M. provides the player character with her own Jackpot missions and occasionally provides information about other Railroad missions.
 * P.A.M. will not initiate Railroad radiant quests once the quest Tactical Thinking has started, but will talk again if that quest fails (for example doing The Nuclear Option (Railroad) or The Nuclear Option (Minutemen)).
 * Even after the completion of Tactical Thinking and the total destruction of the Railroad, P.A.M. will still give out some Railroad radiant quests to the player character, such as Variable Removal quests.

Appearances
P.A.M. appears in Fallout 4.

Bugs

 * Selecting the "Maybe later" response may lead to it not giving any more quests and the player will not be able to speak to it beyond the initial greeting.
 * One can use the console command to fix this.
 * On console, loading a save before the interaction will fix this issue.
 * Responding with the "not interested" reply after P.A.M. briefs you about a mission may lead to her constantly being busy and not initiating dialogue, even when you are prompted to speak to it by Drummer Boy.
 * P.A.M. will sometimes send the player to Far Harbor prior to the start of Far From Home as well as Nuka-world prior to starting All Aboard for a radiant quest.
 * If P.A.M. is reprogrammed and brought back to the Prydwen after the completion of Tactical Thinking, the quest Variable Removal will still be given.
 * One can use the console command to fix this.
 * If Blind Betrayal is completed, she will go into lockdown mode even if the Sole Survivor hasn't talked to Lancer Captain Kells or become an enemy of the Railroad. This makes it impossible to receive or complete quests where P.A.M. must be talked to. This can be fixed by becoming an enemy of the Brotherhood of Steel, but not by having Danse as a companion to temporarily be an enemy of the Brotherhood of Steel.
