Si l’approche pour construire un agent est simple, comme une chaîne de <em>prompts</em>, utiliser du code simple peut suffire. L’avantage est que le développeur aura <strong>un contrôle total et une compréhension de son système sans abstractions</strong>.</p> <p data-svelte-h="svelte-mw7a37">Cependant, lorsque le <em>workflow</em> devient plus complexe, comme laisser un LLM appeler des fonctions ou utiliser plusieurs agents, ces abstractions commencent à devenir utiles.</p> <p data-svelte-h="svelte-1270tfb">En considérant ces idées, nous pouvons déjà identifier le besoin de certaines fonctionnalités :</p> <ul data-svelte-h="svelte-1ivq4n5"><li>Un <em>moteur LLM</em> qui alimente le système.</li> <li>Une <em>liste d’outils</em> auxquels l’agent peut accéder.</li> <li>Un <em>analyseur</em> pour extraire les appels d’outils de la sortie du LLM.</li> <li>Un <em>prompt système</em> synchronisé avec l’analyseur.</li> <li>Un <em>système de mémoire</em>.</li> <li>Des <em>mécanismes de journalisation des erreurs et de réessai</em> pour contrôler les erreurs du LLM.</li></ul> <p data-svelte-h="svelte-1usrhap">Nous explorerons comment ces sujets sont résolus dans divers <em>frameworks</em> comme <code>smolagents</code>, <code>LlamaIndex</code> et <code>LangGraph</code>.</p> <h2 class="relative group"><a id="unités-des-frameworks-agentiques" 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="#unités-des-frameworks-agentiques"><span><svg class="" 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>Unités des frameworks agentiques</span></h2> <table data-svelte-h="svelte-bt3swt"><thead><tr><th><em>Framework</em></th> <th>Description</th> <th>Auteur de l’unité</th></tr></thead> <tbody><tr><td><a href="./smolagents/introduction">smolagents</a></td> <td><em>Framework</em> d’agents développé par Hugging Face.</td> <td>Sergio PANIEGO - <a href="https://huggingface.co/sergiopaniego" rel="nofollow">HF</a> - <a href="https://x.com/sergiopaniego" rel="nofollow">X</a> - <a href="https://www.linkedin.com/in/sergio-paniego-blanco" rel="nofollow">Linkedin</a></td></tr> <tr><td><a href="./llama-index/introduction">Llama-Index</a></td> <td>Outils de bout en bout pour déployer un agent IA augmenté par le contexte en production</td> <td>David BERENSTEIN - <a href="https://huggingface.co/davidberenstein1957" rel="nofollow">HF</a> - <a href="https://x.com/davidberenstei" rel="nofollow">X</a> - <a href="https://www.linkedin.com/in/davidberenstein" rel="nofollow">Linkedin</a></td></tr> <tr><td><a href="./langgraph/introduction">LangGraph</a></td> <td>Agents permettant l’orchestration étatique des agents</td> <td>Joffrey THOMAS - <a href="https://huggingface.co/Jofthomas" rel="nofollow">HF</a> - <a href="https://x.com/Jthmas404" rel="nofollow">X</a> - <a href="https://www.linkedin.com/in/joffrey-thomas" rel="nofollow">Linkedin</a></td></tr></tbody></table> <a class="!text-gray-400 !no-underline text-sm flex items-center not-prose mt-4" href="https://github.com/huggingface/agents-course/blob/main/units/fr/unit2/introduction.mdx" target="_blank"><svg class="mr-1" 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="M31,16l-7,7l-1.41-1.41L28.17,16l-5.58-5.59L24,9l7,7z"></path><path d="M1,16l7-7l1.41,1.41L3.83,16l5.58,5.59L8,23l-7-7z"></path><path d="M12.419,25.484L17.639,6.552l1.932,0.518L14.351,26.002z"></path></svg> <span data-svelte-h="svelte-zjs2n5"><span class="underline">Update</span> on GitHub</span></a> <p></p>
