Description
DeepSeek, founded in 2023, focuses on researching world-leading foundational models and technologies for general artificial intelligence, tackling cutting-edge AI challenges. Leveraging self-developed training frameworks and extensive computing resources, they have rapidly open-sourced multiple large models, including DeepSeek-LLM, DeepSeek-Coder, and China's first DeepSeek-MoE in January 2024. These models show superior performance in benchmarks and can be accessed via API.
LangChain provides the engineering platform and open-source frameworks for developers to build, test, and deploy reliable AI agents. It offers SDKs in Python, TypeScript, Go, and Java, along with tools for analytics, AI-driven insights, and reusable evaluation methods. The platform supports human-in-the-loop interactions and scalable, distributed runtimes for complex agent swarms.
