LangGraph: Building a Flexible, Opinionated AI Coding Assistant

2025-03-24

Qodo built an AI coding assistant using the LangGraph framework, balancing flexibility with adherence to coding best practices. Initially, they used predefined workflows for coding tasks, but with the advent of more powerful LLMs like Claude Sonnet 3.5, they shifted to LangGraph's graph-based approach. LangGraph allows building agents ranging from completely open-ended to fully structured deterministic flows, enabling Qodo to adjust the structure of their flows based on LLM capabilities. The framework's clean API, reusable components, and built-in state management simplified development and support persistence, checkpoints, and branch points. While documentation and testing present some challenges, LangGraph provided a solid foundation for Qodo to build a robust AI coding assistant.

Qodo Gen 1.0: Agentic AI Coding with LangGraph and MCP

2025-03-18

Qodo Gen 1.0 introduces agentic workflows in its AI coding and testing IDE plugin, enabling AI to dynamically decide how to navigate complex coding tasks. This was achieved by restructuring the infrastructure using LangGraph for structured workflows and Anthropic's Model Context Protocol (MCP) for standardized external tool integration. The architecture supports asynchronous communication, on-demand context retrieval, and enhanced error handling and reliability, allowing the AI to operate autonomously, retrieve real-time data, and adapt strategies based on tool execution results. LangGraph provides flexibility and control, while MCP simplifies external tool integration. The result is more intelligent automation, an extensible system, and a structured approach to AI autonomy.

Qodo-Embed-1: A Family of Efficient, Small Code Embedding Models

2025-03-03

Qodo announced Qodo-Embed-1, a new family of code embedding models achieving state-of-the-art performance with a significantly smaller footprint than existing models. The 1.5B parameter model scored 68.53 on the CoIR benchmark, surpassing larger 7B parameter models. Trained using synthetic data generation to overcome limitations of existing models in accurately retrieving code snippets, Qodo-Embed-1 significantly improves code retrieval accuracy and efficiency. The 1.5B parameter model is open-source, while the 7B parameter model is commercially available.

Building a Robust Evaluation Framework for RAG Systems

2025-02-14

Qodo built a Retrieval Augmented Generation (RAG)-based AI coding assistant and developed a robust evaluation framework to ensure accuracy and comprehensiveness. Challenges included verifying the correctness of RAG outputs derived from large, private datasets. The framework evaluates the final retrieved documents and the final generated output, focusing on 'answer correctness' and 'retrieval accuracy'. To address the challenges of natural language outputs, they employed an 'LLM-as-judge' approach and built a ground truth dataset with real questions, answers, and context. For efficiency, they leveraged LLMs to assist in dataset construction and used LLMs and RAGAS to evaluate answer correctness. Ultimately, they built their own LLM judge and combined it with RAGAS for improved reliability, integrating it into their workflow with regression testing, dramatically reducing the effort to verify code changes' impact on quality.

Qodo Merge 1.0: AI-Powered Code Review Evolves

2025-02-02

Qodo Merge 1.0, an AI-driven code review tool, addresses inherent challenges in AI-assisted coding after over a year of development. The new version features a focus-on-problems mode prioritizing critical issues like bugs and security flaws; dynamic learning that refines suggestions based on accepted changes; real-time ticket context integration; and a `/implement` command to translate feedback into actionable code changes. Qodo Merge 1.0 makes code review more precise, adaptive, and efficient.

Effective AI Code Suggestions: Less is More

2025-01-29

Qodo (formerly Codium) discovered a crucial lesson in using LLMs for code review with its AI-powered tool, Qodo Merge. Initially, prioritizing bug detection over style suggestions proved ineffective; the model got overwhelmed by the easier-to-find style issues, leading to suggestion fatigue among developers. The breakthrough came from simplifying the model's task: focusing solely on finding meaningful bugs and problems. This laser focus increased bug detection rates and the signal-to-noise ratio, resulting in a 50% jump in suggestion acceptance rates and an 11% increase in overall impact. The key takeaway: sometimes, eliminating distractions is more effective than complex prioritization.
