Last week, I spent some time on the DeepSeek OCR paper with @LoganMarkewich and it was genuinely interesting.

It's definitely not just OCR - it's using vision as compression. 10x token reduction while maintaining accuracy.

This past Monday I had the pleasure of joining a panel about open-source and AI, hosted by Merantix at the London AI Hub.

We're opening up early access to LlamaAgents - which allows you to go from local LlamaIndex agent workflows to deployed agents in a matter of minutes.

Wrote about something I've been thinking about lately: how AI coding agents are changing how we build AI agents themselves

At LlamaIndex, we've been experimenting with using coding agents like Cursor and Claude Code to speed up build agentic workflows themselves + their UIs

We're making 𝐯𝐢𝐛𝐞-𝐥𝐥𝐚𝐦𝐚 with and for LlamaIndex a lot easier..

Last week we released vibe-llama, a tool developed by @cle-does-things.bsky.social

This is not GraphRAG, it comes before..

Last week, me and Tomaz (from neo4j) published another demo together. The idea: you have a bunch of unstructured documents (think legal, PDFs etc) and you want to construct a knowledge graph out of them.

OpenAI just dropped new open source models 🔥

My colleague Logan spent his morning testing gpt-oss-20b - which runs on consumer hardware, is Apache 2.0 licensed, and the reasoning quality is solid.

Also, full chain-of-thought access so you can see exactly how it's thinking.

Last week @cle-does-things.bsky.social and I created @llamaindex.bsky.social nodes for @n8n.io

Here's what we got:
· LlamaExtract: use extraction agents within n8n workflows
· LlamaParse: parse complex documents
· LlamaCloud: use your existing LlamaCloud indexes as knowledge bases within n8n

A new walkthrough for a research agent using Llamaindex and Google Gemini, fresh out the oven. Given a topic:

🌎 Use Gemini 2.5 pro with its server side google search tool
📝 Create an agent that takes notes as it gets results from its websearch

I like this new terminology around context engineering that's picking up. It's a good way to think about how to build actually effective agentic applications.

Since MCP there are questions about whether it removes the need for you to build your own RAG workflows with vector search. And my answer to that is:

Last week, we concluded the @gradio-hf.bsky.social‬ MCP hackathon with @hf.co‬. The project that one the @llamaindex.bsky.social prize was the "Nasa Space Explorer" 🔭🪐
3 servers that provide live data on:
☄️ Asteroids
🤖 the Mars Rover
🌌 Astronomy

Yesterday Zoom announced Zoom RTMS at the developer summit, which gives you real-time access to audio, video, and transcript data from Zoom Meetings.

🍕 Since the first @llamaindex.bsky.social‬ office hours with Logan a specific use-case kept popping up: incremental "form filling".
So, here's a pizzeria order taking assistant using just that with the new Artifact Memory Block and Artifact Editor Tool: colab.research.google.com/drive/13ORO...

A new oss image generation agent by mu colleague Clelia, that doesn't _just_ generate images.
Structured outputs with Google Gemini to check the generated image and evaluate whether it's ready for the user or not.

LlamaExtract (by @llamaindex.bsky.social) allows you to turn on citations and reasoning to check:
1️⃣ The underlying models reasoning for the assignment and
2️⃣ The citations from the source document

Numerous ways to build agents, numerous workflow patterns and applications.

On April 29th we will be hosting a live session where we dive into @weaviate.bsky.social agents, how you can use them, and all of our future agentic plans! Join us 👇

Build a personal shopping assistant in less than 5 minutes with the new @weaviate.bsky.social Query Agent!

👩‍🍳 To get started, try out the recipe! You’ll end up building an e-commerce assistant agent: colab.research.google.com/github/weavi...

There are valid concerns when it comes to how we use agents today and how we should prepare to use them in future.

1️⃣ AI agents as ‘research assistants’,
2️⃣ Agentic workflows, some involving human-in-the-loop systems.
3️⃣ Safety nets, such as ‘undo’.

Agents can seem a bit like wizardry, so I've been working on an intro 💚

🧙 The way I like to explain it is by comparing most LLMs in agentic AI applications today to a wizard with a spell book (tools). It's been granted instructions for bunch of spells 🪄

I built a 'game recommender service' with the new @deepseek.bsky.social model using Ollama 🦙 and @weaviate.bsky.social
😈 Here's the recipe and the fancy graphic I created for it

Stepping out of my usual content here and jumping in to Greek mythology. I’ve gotten really into it in the last few years and just finished Stone Blind by Natalie Haynes.

Beautifully written. Would highly recommend this retelling of the story of Medusa.

I have a new hobby that involves lots of fire 🔥 Behold my first ring that has a stone setting 💍

Gave my first first talk at @weaviate.bsky.social this past Wednesday 🚀

We created a mini Weaviate assistant agent by defining our own 2 tools:
· A Weaviate Docs RAG tool
· A Weaviate GitHub Issues RAG tool
I used @llamaindex.bsky.social for this demo

The best swag I ever got was from the GitHub HQ in SF. Grateful for this little ball of lip balm in the cold Amsterdam weather today.
