Learn - PraisonAI

learn extracts durable learnings after each turn and folds them back into the next system prompt.

Quick Start

Enable agentic learning

import { Agent } from 'praisonai';

const agent = new Agent({ instructions: 'Assist the user', learn: 'agentic' });
await agent.chat('Remember I prefer metric units');
await agent.chat('How tall is Everest?'); // answer respects the learned preference

learn: true is the same as learn: 'agentic'.

Propose instead of applying

const agent = new Agent({ instructions: 'Assist', learn: 'propose' });

Modes

Mode	Behaviour
`'agentic'`	Extracts and applies learnings automatically.
`'propose'`	Extracts learnings as proposals rather than applying them.
`'disabled'`	Off (same as omitting `learn`).

Injection and nudges

After a turn, the manager extracts learnings and injects a Learned Insights block into the next system prompt. Two fields on LearnConfig add periodic reminders:

Field	Default	Effect
`nudgeInterval`	`0`	Turns between `[System nudge]` reminders (0 disables).
`nudgeMinToolIters`	`3`	Minimum tool iterations before a nudge fires.

import { Agent } from 'praisonai';

const agent = new Agent({
  instructions: 'Assist',
  learn: { mode: 'agentic', nudgeInterval: 5, nudgeMinToolIters: 3 },
});

An unsupported learn value disables learning with a warning rather than throwing — e.g. learn: 'sometimes' logs Unsupported learn= value "sometimes"; ... Learning disabled.

Reading the manager

import { Agent } from 'praisonai';

const agent = new Agent({ instructions: 'x', learn: 'agentic' });
console.log(agent.getLearnManager()); // the lazily-built manager, or undefined
