Spotlight: Qodo Innovates Efficient Code Search with NVIDIA DGX
Qodo, a multi-agent code integrity platform, built its AI agents on retrieval-augmented generation powered by a state-of-the-art code embedding model trained on NVIDIA DGX. Qodo fine-tuned two embedding models, Qodo-Embed-1-1.5B and Qodo-Embed-1-7B (based on Qwen), achieving state-of-the-art accuracy on the Hugging Face MTEB CoIR leaderboard in their size categories. In a collaboration with NVIDIA, Qodo's code indexer, RAG retriever, and embedding model were substituted into NVIDIA's internal RAG solution (Genie) for searching private code repositories, integrated into NVIDIA's internal Slack system, yielding more detailed and accurate responses to technical questions from expert C++ developers than the original pipeline, evaluated using Ragas-generated synthetic questions against RTXDI, RTXGI and RTXPT SDK repositories.

Inspect the highlighted sourceThe challenge
Large language models help developers write code faster, but face limitations understanding the nuances of programming languages, complex dependencies, and codebase-specific context, which can lead to lower-quality code and bottlenecks; general-purpose embedding models focus on language patterns rather than code-specific elements like syntax, variable dependencies, control flow and API usage, leading to imprecise code retrieval.
The solution
Qodo built its AI agents on retrieval-augmented generation (RAG), a code-specific indexing pipeline with language-specific static analysis for chunking, and a state-of-the-art code embedding model trained on an NVIDIA DGX 8x A100 80GB node using bfloat16 precision and large micro-batch sizes. Qodo fine-tuned two embedding models, Qodo-Embed-1-1.5B and Qodo-Embed-1-7B, based on the Qwen open-source LLM. In collaboration with NVIDIA, Qodo's code indexer, RAG retriever and embedding model were substituted into NVIDIA's internal Genie RAG pipeline for searching private code repositories, integrated into NVIDIA's internal Slack system.
Reported business value
Qodo's fine-tuned embedding models achieved state-of-the-art accuracy, leading the Hugging Face MTEB CoIR leaderboard in their respective size categories. In a case study evaluated with Ragas-generated synthetic questions against the RTXDI, RTXGI and RTXPT SDK repositories, the Qodo-based pipeline yielded more detailed and accurate responses to technical questions from expert C++ developers than NVIDIA's original Genie pipeline.

HP crafts marketing campaigns that resonate with customers using Databricks and Uniphore
HP centralized first-party customer data on the Databricks Data + AI Platform with Delta Lake and Unity Catalog, and connected it to Uniphore's HybridCompute for federated query pushdown, cutting campaign setup from 2 weeks to 2 hours and processing 400 million records in seconds.
Building a safer and more sustainable world
Novade, a construction management software company, partnered with Databricks to modernize its analytics and ML infrastructure, moving from a homegrown Apache Airflow stack to the Databricks Data + AI Platform with Delta Lake, Unity Catalog and MLflow. The move reduced total cost of ownership by 60% and supported a 100% increase in new clients, while enabling ML models for predicting incident risk affecting worker safety and project delivery schedules.
SafeGraph optimizes geospatial data processing with Databricks and Delta Sharing
SafeGraph used the Databricks Data + AI Platform, Delta Lake, Delta Sharing and MLflow to process petabytes of geospatial data and feed predictive models, achieving 2x-10x faster spatial querying, indexing and partitioning and a 50% reduction in peak memory consumption compared to other platforms, while reducing data access time for partners from months to minutes via Delta Sharing.
Transforming Weather Forecasting with Lakeflow Jobs
AccuWeather migrated from on-premises infrastructure to Databricks and Lakeflow Jobs, working with Datadog for observability, to unify diverse weather data formats and orchestrate 4,500+ weekly jobs. Lakeflow Jobs coordinates the ingestion of multiple weather models, triggers machine learning processes that weight and blend different forecasts, and manages complex job dependencies for reinforcement training workflows used in AccuWeather's proprietary forecasting engine. AccuWeather reports 3x faster dataset development (three months to one month per dataset), a 50% reduction in unactionable alerts, and 50% cost savings on serverless job usage.
