À propos de Dify
Dify est une plateforme open-source de développement d'applications LLM. Son interface intuitive combine un flux de travail IA, un pipeline RAG, des capacités d'agent, la gestion des modèles, des fonctionnalités d'observabilité et plus encore, vous permettant de passer rapidement du prototype à la production.
Fonctionnalités
1. Flux de travail: Créez et testez des flux de travail IA puissants sur un canevas visuel, exploitant toutes les fonctionnalités suivantes et plus encore.
2. Support complet des modèles: Intégration transparente avec des centaines de modèles LLM propriétaires / open-source de dizaines de fournisseurs d'inférence et de solutions auto-hébergées, couvrant GPT, Mistral, Llama3, et tous les modèles compatibles avec l'API OpenAI. Une liste complète des fournisseurs de modèles supportés peut être trouvée ici.
3. IDE de Prompt: Interface intuitive pour créer des prompts, comparer les performances des modèles et ajouter des fonctionnalités supplémentaires comme la synthèse vocale à une application de chat.
4. Pipeline RAG: Des capacités RAG étendues qui couvrent tout, de l'ingestion de documents à la récupération, avec une prise en charge intégrée de l'extraction de texte à partir de PDF, PPT et autres formats de documents courants.
5. Capacités d'agent: Vous pouvez définir des agents basés sur l'appel de fonction LLM ou ReAct, et ajouter des outils préconçus ou personnalisés pour l'agent. Dify fournit plus de 50 outils intégrés pour les agents IA, tels que Google Search, DALL·E, Stable Diffusion et WolframAlpha.
6. LLMOps: Surveillez et analysez les journaux et les performances des applications au fil du temps. Vous pouvez améliorer continuellement les prompts, les jeux de données et les modèles en fonction des données de production et des annotations.
7. Backend-as-a-Service: Toutes les fonctionnalités de Dify sont accompagnées d'API correspondantes, vous permettant d'intégrer facilement Dify dans votre propre logique métier.
