Model (LLM) \u2013 The Brain of the Agent<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The tutorial uses the free <strong>Gemini model<\/strong>.<\/li>\n\n\n\n<li>You can get an API key from <a href=\"https:\/\/aistudio.google.com\">Google AI Studio<\/a><\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2. Memory \u2013 Remembering Conversations<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Memory enables the AI to <strong>retain context<\/strong> across interactions.<\/li>\n\n\n\n<li>In this setup, &#8220;simple memory&#8221; is used with a <strong>session ID<\/strong> to store the last five messages.<\/li>\n\n\n\n<li>This allows the agent to provide coherent, context-aware responses.<br><em>(Timestamp: 06:43)<\/em><\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">3. Tools \u2013 Giving the Agent Superpowers<\/h3>\n\n\n\n<p>Tools define what the agent can <em>do<\/em> beyond chatting.
