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.

Build Text-to-SQL systems with open source Arctic models and agentic workflows 🚀

Our own @tuana.dev is speaking at Snowflake Build to show you how to create powerful data analysis agents that can handle complex, multi-part questions:

An interesting overlap exists between memory and context. And a new(ish) memory block that was added as an integration to @llama_index is (imo) - a great demonstration of that 👉 the Artifact Memory Block

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.

Ok this is prettyyy cool, another ‪@llamaindex.bsky.social‬ workflows implementation from @cle-does-things.bsky.social 👇
July 25, 2025 at 5:28 PM
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
July 14, 2025 at 8:40 PM
Watch as Claude acts as a document agent using LlamaCloud MCP tools to:

- Query any index with custom parsing.
- Use LlamaExtract agents to pull structured data based on LlamaCloud's schema.

The demo features extraction agents for invoices and technical resumes.

With all of this "context engineering" chatter, I've been thinking about how much of LLM performance hinges not just on model architecture, but on how you feed it context a lot lately.

So, co-authored a piece on Context Engineering with Logan:
Here it is:

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.

Today we're announcing the first stable release of @llama_index workflows. A lightweight framework for building complex, multi-step agentic AI applications in Python and Typescript

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:

Tomorrow, I'm joining Laura for a discussion on memory.
Note: not all applications that are 'agentic' necessarily _need_ memory. And what type of memory you need also depends on the use case.

Order Completion Agent with Artifact Editor by @tuana.dev:

Fill out structured forms as the user talks! Checking the completeness along the way:
✅ ArtifactEditorToolSpec to define structured artifacts
✅ ArtifactMemoryBlock to track progress

🍕 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...

We’ve started to host more regular office hours now. Come along to ask anything LlamaIndex 👇
Since you loved it last time, @tuana.dev and Logan are hosting another office hours in the LlamaIndex Discord this Thursday.

This time, the topic of choice will be creating MCP servers with LlamaIndex, and per popular request - form filling agents:
