No hay componentes del modelo, y las salidas incluyen <code>out_prompt</code>, <code>old_prompt</code> y <code>doc</code>.</p> <p>Ahora veamos el diccionario <code>params</code>:</p> <ul><li><p><strong><code>prompt</code></strong>: Un parámetro de entrada con <code>display: "textarea"</code> (se renderiza como un cuadro de entrada de texto), <code>label: "Prompt"</code> (se muestra en la interfaz) y <code>default: ""</code> (comienza vacío). El campo <code>type: "string"</code> es importante en Mellon porque determina qué nodos pueden conectarse entre sí: solo los tipos coincidentes pueden enlazarse con “noodles”.</p></li> <li><p><strong><code>out_prompt</code></strong>: La salida del prompt expandido. El prefijo <code>out_</code> se añadió automáticamente porque la entrada y la salida comparten el mismo nombre (<code>prompt</code>), evitando conflictos de nombres en la configuración. Tiene <code>display: "output"</code>, lo que se renderiza como un socket de salida.</p></li> <li><p><strong><code>old_prompt</code></strong>: Tiene <code>type: "custom"</code> porque no especificamos metadatos. Esto se renderiza como un punto simple en la interfaz. Dado que en realidad no queremos exponerlo en la interfaz, podemos eliminarlo.</p></li> <li><p><strong><code>doc</code></strong>: La salida de la documentación, añadida automáticamente a todos los bloques personalizados.</p></li></ul> <!--[2--><h3 class="relative group"><a id="making-adjustments" class="header-link block pr-1.5 text-lg no-hover:hidden with-hover:absolute with-hover:p-1.5 with-hover:opacity-0 with-hover:group-hover:opacity-100 with-hover:right-full" href="#making-adjustments"><span><svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" aria-hidden="true" role="img" width="1em" height="1em" preserveAspectRatio="xMidYMid meet" viewBox="0 0 256 256"><path d="M167.594 88.393a8.001 8.001 0 0 1 0 11.314l-67.882 67.882a8 8 0 1 1-11.314-11.315l67.882-67.881a8.003 8.003 0 0 1 11.314 0zm-28.287 84.86l-28.284 28.284a40 40 0 0 1-56.567-56.567l28.284-28.284a8 8 0 0 0-11.315-11.315l-28.284 28.284a56 56 0 0 0 79.196 79.197l28.285-28.285a8 8 0 1 0-11.315-11.314zM212.852 43.14a56.002 56.002 0 0 0-79.196 0l-28.284 28.284a8 8 0 1 0 11.314 11.314l28.284-28.284a40 40 0 0 1 56.568 56.567l-28.285 28.285a8 8 0 0 0 11.315 11.314l28.284-28.284a56.065 56.065 0 0 0 0-79.196z" fill="currentColor"></path></svg><!----></span></a> <span><!---->Realizar ajustes<!----></span></h3><!--]--><!----> <p>Elimina <code>old_prompt</code> de <code>params</code> y <code>output_names</code> porque no lo necesitarás.</p> <div class="code-block relative "><div class="absolute top-2.5 right-4"><button class="inline-flex items-center relative text-sm focus:text-green-500 cursor-pointer focus:outline-none transition duration-200 ease-in-out opacity-0 mx-0.5 text-gray-600 " title="code excerpt" type="button"><svg xmlns="http://www.w3.org/2000/svg" aria-hidden="true" fill="currentColor" focusable="false" role="img" width="1em" height="1em" preserveAspectRatio="xMidYMid meet" viewBox="0 0 32 32"><path d="M28,10V28H10V10H28m0-2H10a2,2,0,0,0-2,2V28a2,2,0,0,0,2,2H28a2,2,0,0,0,2-2V10a2,2,0,0,0-2-2Z" transform="translate(0)"></path><path d="M4,18H2V4A2,2,0,0,1,4,2H18V4H4Z" transform="translate(0)"></path><rect fill="none" width="32" height="32"></rect></svg><!----> <div class=" absolute pointer-events-none transition-opacity bg-black text-white py-1 px-2 leading-tight rounded font-normal shadow left-1/2 top-full transform -translate-x-1/2 translate-y-2 opacity-0 "><div class="absolute bottom-full left-1/2 transform -translate-x-1/2 w-0 h-0 border-black border-4 border-t-0" style="border-left-color: transparent; border-right-color: transparent;"></div> Copiado</div><!----></button><!----></div> <pre class="language-json "><!----><span class="hljs-punctuation">{</span>
