LangChain's 2024 AI report reveals trends in LLM usage, highlighting the rise of open-source models and AI agents, along with shifts in infrastructure and performance optimization.
The LangChain State of AI 2024 report sheds light on key trends shaping the artificial intelligence landscape, particularly in the realm of Large Language Models (LLMs). According to LangChain, the past year has seen significant shifts in how developers utilize AI technologies, with open-source models gaining traction and a notable rise in the adoption of AI agent applications.
Infrastructure and Model Usage
OpenAI continues to dominate as the most utilized LLM provider among LangChain users, maintaining its lead over other providers such as Ollama and Groq. This trend underscores the growing demand for flexible deployment options and customizable AI infrastructure. Ollama and Groq, which focus on local and cloud execution of open-source models, respectively, have notably entered the top five providers, reflecting a shift towards more adaptable AI solutions.
Open-source model providers like Ollama, Mistral, and Hugging Face have maintained a significant presence, collectively accounting for 20% of the top LLM providers based on organizational usage. This highlights an ongoing interest in open-source solutions within the AI community.
Development Trends and AI Agents
The report indicates a shift from traditional retrieval workflows to more complex, agentic applications. Developers are leveraging LangChain’s frameworks to build dynamic applications, with observability extending beyond LangChain-specific tools. Interestingly, 15.7% of LangSmith traces originate from non-LangChain frameworks, demonstrating a trend towards interoperability in AI development.
Python remains the dominant language for LLM app development, although JavaScript is gaining popularity, driven by the need for web-first applications. The JavaScript SDK’s usage has tripled over the past year, accounting for 15.3% of LangSmith usage.
AI agents are becoming more prevalent, with LangGraph, LangChain’s agent framework, seeing increased adoption. Since its release in March 2024, 43% of LangSmith organizations have started utilizing LangGraph, indicating a growing interest in applications that involve complex, orchestrated tasks.
Performance Optimization and Evaluation
Developers are increasingly focusing on balancing complexity and performance. The average number of steps per trace has more than doubled, rising from 2.8 in 2023 to 7.7 in 2024, indicating more sophisticated workflows. However, the average number of LLM calls per trace has only slightly increased, suggesting that developers are optimizing their applications to achieve more with fewer resources.
To ensure the quality of LLM-generated responses, organizations are employing LangSmith’s evaluation capabilities. Using LLM-as-Judge evaluators, developers are testing for relevance, correctness, and helpfulness, ensuring that AI outputs meet specific criteria. Human feedback remains integral to the development process, with annotated runs increasing 18-fold over the past year.
Conclusion
The LangChain State of AI 2024 report highlights a year marked by increased complexity in AI applications, a focus on efficiency, and enhanced quality control measures. As developers continue to innovate, the AI ecosystem is set to evolve with smarter workflows, improved performance, and greater reliability.
