We are thrilled to team up with Timescale to bring the community our newest challenge. We think you'll like this one.
Running through November 10, the Open Source AI Challenge with pgai and Ollama provides an opportunity to build with AI and experience the power of Postgres – all within the open source ecosystem!
Whether you’re new to coding or have been in the industry for years, this will be a fun way to learn something new and stretch your creativity. There is one prompt for this challenge but four ways to win.
We hope you give it a try!
Our Prompt
Your mandate is to build an AI application using open-source tools and the open-source database PostgreSQL as your vector database, using two or more of the following related tools: pgvector, pgvectorscale, pgai, and pgai Vectorizer.
PostgreSQL offers a number of extensions for AI (pgvector, pgvectorscale, and pgai) making it possible to power AI applications like search, RAG, and AI Agents without using a separate vector database.
Additional Prize Categories
In addition to being able to win the overall prompt, we have three additional prize categories you can work towards!
- Open-source Models from Ollama: Awarded to a project that utilizes open-source LLMs via Ollama for embedding and/or generation models.
- Vectorizer Vibe: Awarded to a project that leverages the pgai Vectorizer tool for embedding creation in their RAG application.
- All the Extensions!: Awarded to a project that leverages all three of the PostgreSQL extensions for AI: pgvector, pgvectorscale, and pgai.
Be sure to indicate all the categories your project may qualify for as part of your submission.
Judging Criteria and Prizes
All three prompts will be judged on the following:
- Use of underlying technology
- Usability and User Experience
- Accessibility
- Creativity
- If applicable, additional prize category requirements
Overall Prompt Winner (1) will receive:
- $1,500 USD
- 6 Month DEV++ Membership
- Exclusive DEV Badge
- A gift from the DEV Shop
Prize Category Winners (3) will receive:
- $500 USD
- 6 Month DEV++ Membership
- Exclusive DEV Badge
- A gift from the DEV Shop
All Participants with a valid submission will receive a completion badge on their DEV profile.

pgvectorscale
A complement to pgvector for high performance, cost efficient vector search on large workloads.
pgvectorscale
pgvectorscale builds on pgvector with higher performance embedding search and cost-efficient storage for AI applications.
pgvectorscale complements pgvector, the open-source vector data extension for PostgreSQL, and introduces the following key innovations for pgvector data:
- A new index type called StreamingDiskANN, inspired by the DiskANN algorithm, based on research from Microsoft.
- Statistical Binary Quantization: developed by Timescale researchers, This compression method improves on standard Binary Quantization.
On a benchmark dataset of 50 million Cohere embeddings with 768 dimensions
each, PostgreSQL with pgvector and pgvectorscale achieves 28x lower p95
latency and 16x higher query throughput compared to Pinecone's storage
optimized (s1) index for approximate nearest neighbor queries at 99% recall
all at 75% less cost when self-hosted on AWS EC2.
To learn more about the performance impact of pgvectorscale, and details about benchmark methodology and results, see the pgvector vs Pinecone comparison blog post.
In contrast to pgvector, which…

pgai
A suite of tools to develop RAG, semantic search, and other AI applications more easily with PostgreSQL
pgai allows you to develop RAG, semantic search, and other AI applications directly in PostgreSQL
pgai simplifies the process of building search Retrieval Augmented Generation (RAG), and other AI applications with PostgreSQL. It complements popular extensions for vector search in PostgreSQL like pgvector and pgvectorscale, building on top of their capabilities.
Overview
The goal of pgai is to make working with AI easier and more accessible to developers. Because data is the foundation of most AI applications, pgai makes it easier to leverage your data in AI workflows. In particular, pgai supports:
Working with embeddings generated from your data:
- Automatically create and sync vector embeddings for your data (learn more)
- Search your data using vector and semantic search (learn more)
- Implement Retrieval Augmented Generation inside a single SQL statement (learn more)
- Perform high-performance, cost-efficient ANN search on large vector workloads with pgvectorscale…

This looks awesome! I love hackathons!
Good luck everyone!
I don't think my 5 years old laptop with 512mb of GPU ram will be able to run a 7B LLM 😂
YAY!!!
Is this compatible with the Open Source AI Definition just ratified by the OSI, please? I don't see Ollama on the list of endorsements there.
Depends on the model you are using. Ollama is basically just a wrapper for llama.cpp and llama.cpp serves as a host for the interference with an LLM. Both, Ollama and Llama.cpp are published under open source licenses, but there are models which are not open source.
Yes, so the answer is (I think) that this contest is not compatible with the OSI Open Source AI Definition. Thanks.
If we want to utilize Ollama model, does that mean that we have to host the model ourselves and open the access to public?
Did you get an answer for your question? I think we have to deploy the model, otherwise how would the judges try the mout?
So many questions since I'm not familiar with LLMs at all:
hell yeah
