Andrej Karpathy built a video platform in a weekend using Claude and H - OpenSmartRoute
Andrej Karpathy created a new video platform in just one weekend. He used artificial intelligence (AI) tools to do it quickly. The platform, called HackerTube, shows videos based on two decades of Hacker News comments. This project shows how AI can speed up building new online services. It also offers a different way to recommend videos, which could improve user experience. The work highlights how AI can help developers make useful tools faster than before.
Details of HackerTube - data sources and features
HackerTube gathers data from a large collection of comments on Hacker News. Hacker News is a website where people share and discuss technology news. It has been active for over 20 years. Karpathy used an AI model to analyze 43 million comments from this site. From this analysis, the AI selected 6,454 videos to recommend. These videos are chosen to match what users might find interesting.
The platform has several features. It does not require users to log in. Instead, it shows a single frame from each video, instead of a thumbnail. This makes browsing faster and simpler. The videos are recommended based on AI filtering, not just popularity. The site stores some information locally in the browser. This helps keep the experience smooth and fast. Overall, HackerTube offers a curated, easy-to-use video experience based on a large, historical data set.
Use of Claude's Opus 5.5 model - capabilities and role
Karpathy used a specific AI model called Claude's Opus 5.5. This model is designed to understand and process large amounts of text. It can analyze comments, identify relevant content, and generate summaries or recommendations. In this project, the model filtered and distilled the comments into video suggestions.
Claude's capabilities include understanding context, summarizing information, and making recommendations. It can handle complex data analysis tasks that would normally take a lot of time. Karpathy relied on this model to do nearly all the work involved in creating HackerTube. The AI filtered millions of comments and selected videos without manual effort. This shows how powerful AI models are becoming for building data-driven applications.

Building TristanTube - process and tools used
After creating HackerTube, Karpathy built another platform called TristanTube. This site was made using a different AI tool, Claude Code. He used this tool to generate the site in just three minutes. TristanTube features 47,000 videos, which were selected from a list of YouTube channels. The process was fast because the AI handled most of the work.
Karpathy used a simple process to build TristanTube. He provided the AI with a list of channels and asked it to generate a site that displays their videos. The AI took care of setting up the server, organizing the videos, and creating the user interface. The only manual steps involved were getting a Google Cloud API key, renting a server, and buying a domain name. This shows how AI tools can dramatically reduce development time.
Automation and speed - how AI reduces project time
Karpathy emphasizes that AI can cut project time from weeks to hours. He used Claude to analyze data and generate websites quickly. Most of the work was automated, with minimal manual input. This speed allows developers to test ideas faster and iterate more often.
Using AI for automation also reduces errors. Since the AI handles complex tasks, it can produce consistent results. Developers can focus on defining goals and reviewing outputs instead of doing repetitive work. This approach makes building new tools more accessible and less costly. It also enables rapid prototyping, where new ideas can be tested in a matter of hours.
Background on Claude and Hacker News - context for newcomers
Claude is an AI model designed to understand and generate human-like text. It can analyze large datasets, summarize information, and assist with decision-making. The Opus 5.5 version is one of its latest releases, known for its ability to handle complex tasks efficiently.
Hacker News is a social news website focused on technology and startup topics. It has been active for more than 20 years, accumulating a vast archive of comments and discussions. These comments reflect the interests and trends in the tech community over time. By analyzing this data, AI models can identify popular topics and relevant content for various applications.
This project shows how AI models like Claude can process large, unstructured data sources to create new services. It also demonstrates how existing online communities can be leveraged for data-driven content curation.
Implications for AI development - benefits of rapid prototyping
This example highlights the advantages of using AI for rapid prototyping. Developers can create functional prototypes in hours instead of weeks. AI tools handle data analysis, content generation, and even site setup. This reduces the time and effort needed to test new ideas.
Rapid prototyping helps teams learn quickly what works and what does not. It allows for faster feedback and iteration. This approach can accelerate innovation in AI and software development. It also lowers the barrier for smaller teams or individual developers to experiment with new concepts.
AI-driven prototyping can lead to better products. It enables more experimentation and creativity. As AI tools improve, building and testing new applications will become even faster and more efficient.
How OpenSmartRoute helps
OpenSmartRoute is an open-source router designed for AI requests. It directs each request to the best-fit model, agent, or tool from a predefined catalog. It scores candidates based on quality, cost, speed, and safety. Teams can set weights for each factor to match their priorities.
OpenSmartRoute supports models from any provider compatible with OpenAI. It can serve open-weight models locally and work with tools and agents. The router learns from outcomes, giving more traffic to successful models. It also tracks costs and performance in a savings ledger. This helps teams optimize AI request routing for speed, cost, and safety.
Using OpenSmartRoute, teams can efficiently manage multiple AI models. They can quickly adapt to new models and set rules for data privacy and regional restrictions. This makes it easier to build scalable, cost-effective AI applications.
How it compares - what existed before, what this changes and what stays the same
Before, building a curated video platform required many manual steps. Developers had to gather data, analyze it, and set up servers. This process could take weeks or months. They often relied on traditional content filtering and recommendation algorithms. These methods used basic metrics like views, likes, or simple keyword matching.
What Andrej Karpathy did changes this process. He used Claude, an AI model, to analyze large amounts of data quickly. Instead of manual filtering, Claude distilled 20 years of Hacker News comments into a small set of videos. This approach reduces the time needed to create a curated platform from weeks to hours. It also improves the quality of recommendations by using AI to understand content better.
This new method keeps some things the same. The goal of providing relevant, engaging content remains. The use of cloud services and APIs continues. The need for a domain and basic server setup stays the same. However, the way data is processed and recommendations are generated now relies heavily on AI models like Claude.
The change mainly lies in automation and speed. AI handles tasks that used to require manual effort. This allows for faster iteration and more personalized content curation. Teams can now build similar platforms or tools in a fraction of the time.
