Agent Framework / shim to use Pydantic with LLMs

Kaggle is the world’s largest data science community with powerful tools and resources to help you achieve your data science goals.

The first generation of AI-powered products (often called “AI Wrapper” apps, because they “just” are wrapped around an LLM API) were quickly brought to market by small teams of engineers, …

An LLM Query Understanding Service Doug Turnbull recently wrote about how all search is structured now: “Many times, even a small open source LLM will be able to turn a search query into reasonable structure at relatively low cost.”

As more people start hacking around with implementations of MCP (the Model Context Protocol, a new standard for making tools available to LLM-powered systems) the security implications of tools built on that protocol are starting to come into focus.

If you've been wanting to learn MCP, this is a great place to start. In this tutorial you'll build a simple agent with PydanticAI, and then add an MCP server called fetch, which enables web browsing. Then we'll use the Postgres MCP server to add database querying to our agent. Then we'll use Riza's remote MCP server to add a code interpreter to our agent.

Pydantic Evals Brand new package from the Pydantic AI team which directly tackles what I consider to be the single hardest problem in AI engineering: building evals to determine if your LLM-based system is working correctly and getting better over time.

Everyone is starting to realize how big of a deal Claude’s Model Context Protocol (MCP) is - it’s the first ever “standard” for connecting LLMs with services like your database, Slack, GitHub, web search, etc. It’s VERY powerful and not well understood by many, so in this video I break down everything you need to know about MCP at a high level. I go quick here unlike my usual videos, but I call out a bunch of different resources you can use to dive into anything deeper that you’re curious about - MCP architecture, building your own MCP server, integrating your custom AI agent with MCP, etc. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Check out Stagehand, an incredible tool to crawl and scrape websites with natural language which I used in this video: https://github.com/browserbase/stagehand And here is the Stagehand MCP server that I showcased (you will need a Browserbase API key which is free to start!): https://github.com/browserbase/mcp-server-browserbase/blob/main/stagehand/README.md ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Documentation for Claude’s MCP: https://modelcontextprotocol.io/introduction List of MCP Servers on GitHub: https://github.com/modelcontextprotocol/servers Example n8n MCP Agent: https://github.com/coleam00/ottomator-agents/tree/main/n8n-mcp-agent n8n Community Node for MCP: https://github.com/nerding-io/n8n-nodes-mcp Example Pydantic AI MCP Agent: https://github.com/coleam00/ottomator-agents/tree/main/pydantic-ai-mcp-agent Dive deep into the architecture of MCP: https://modelcontextprotocol.io/docs/concepts/architecture ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 00:00 - MCP is Blowing Up 01:55 - What is MCP? 03:12 - Making MCP "Click" (Deep Dive with Diagrams) 05:33 - How Agents Work with MCP 07:16 - Word of Caution - What MCP Isn't 08:17 - Where You Can Use MCP 09:47 - MCP Servers You Can Use NOW 11:18 - How to Set Up MCP Servers 12:08 - Using MCP Servers in Claude Desktop 13:11 - MCP Demo in Claude Desktop (Brave + Stagehand) 14:09 - Building with MCP (Servers and Clients) 15:22 - Building Your Own MCP Server 18:09 - MCP with n8n AI Agents 20:10 - MCP with Python AI Agents 21:56 - The Future of MCP 23:51 - Outro ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Join me as I push the limits of what is possible with AI.

Note that DeepSeek-V2 paper claims a KV cache size reduction of 93.3%. They don’t exactly publish their methodology, but as far as I can tell it’s something likes this: start with Deepseek-v2 hyperparameters here: https://huggingface.co/deepseek-ai/DeepSeek-V2/blob/main/configuration_deepseek.py. num_hidden_layers=30, num_attention_heads=32, v_head_dim = 128. If DeepSeek-v2 was implemented with traditional MHA, then KV cache size would be 2*32*128*30*2=491,520 B/token. With MLA with a KV cache size of 576, we get a total cache size of 576*30=34,560 B/token. The percent reduction in KV cache size is then equal to (491,520-34,560)/492,520=92.8%. The numbers I present in this video follow the same approach but are for DeepSeek-v3/R1 architecture: https://huggingface.co/deepseek-ai/DeepSeek-V3/blob/main/config.json. num_hidden_layers=61, num_attention_heads=128, v_head_dim = 128. So traditional MHA cache would be 2*128*128*61*2 = 3,997,696 B/token. MLA reduces this to 576*61*2=70,272 B/token. Tor the DeepSeek-V3/R1 architecture, MLA reduces the KV cache size by a factor of 3,997,696/70,272 =56.9X. 2. I claim a couple times that MLA allows DeepSeek to generate tokens more than 6x faster than a vanilla transformer. The DeepSeek-V2 paper claims a slightly less than 6x throughput improvement with MLA, but since the V3/R1 architecture is heavier, we expect a larger lift, which is why i claim “more than 6x faster than a vanilla transformer” - in reality it’s probably significantly more than 6x for the V3/R1 architecture. 3. In all attention patterns and walkthroughs, we’re ignoring the |beginning of sentence| token. “The American flag is red, white, and” actually maps to 10 tokens if we include this starting token, and may attention patterns do assign high values to this token. 4. We’re ignoring bias terms matrix equations. 5. We’re ignoring positional embeddings. These are fascinating. See DeepSeek papers and ROPE.
