A conference sold out three separate ticket tiers before the doors even opened. Not "almost sold out." Sold out — Leadership track, gone. Workshops, gone. Late bird tickets, gone. The organizers stopped counting around 6,000 attendees and said they'd officially call it once they crossed 7,000. That's the AI Engineer World's Fair in 2026, and if you've spent any time building with LLMs over the last three years, you already know the name even if you've never been able to get a ticket. I want to walk you through what's actually happening on the ground this week at Moscone West in San Francisco — not the marketing copy, but the track list, the speaker lineup, and the quiet signals buried in the schedule that tell you where AI engineering is actually heading next.

AI Engineer World's Fair is the flagship conference run by AI Engineer, the company behind a whole circuit of events — the AI Engineer Summit, Code Summit, and standalone editions in London, New York, Paris, Miami, Singapore, Shanghai, and Melbourne. The World's Fair is the biggest of them all: a four-day event with 29 tracks, 300 speakers, 100 expo partners, and more than 6,000 AI engineers, founders, and VPs of AI in attendance. The 2026 edition runs from Monday June 29 through Thursday July 2, with a Sunday evening orientation night tacked on for first-timers. It's held at Moscone West, 747 Howard Street, in San Francisco. This is the fourth year the event has anchored in San Francisco, and the organizers have leaned into that — discounted hotel blocks at the Marriott Marquis, Parc 55, and InterContinental, all walking distance from the venue. The person behind all of it is Shawn "swyx" Wang. He's the cofou

Of all the things involved in turning a woman's life into a 60-second reel, I assumed that the writing would be the easy part. Surely telling a good story in 150 words is exactly what a large language model should be good at; yet it proved surprisingly difficult. Draft after draft suffered from common AI weaknesses: a tendency to use hyperbole and inspirational language, to generalize, follow generic founder arcs ("built in a basement"), and focus on morbid details. (For this effort, I was using Sonnet 4.6, which I found to be better — more grounded, more true to facts, less inventive — than Opus 4.7 at creating longer bios.) Getting to something publishable took a significant amount of work. That said, the human in this story also found writing good short story arcs surprisingly challenging, so the effort spent on getting the system to do it decently was well worth it. Here's some context, then what I did. I've been publishing short biographies of notable women for a while now, on a website called Tycoona . Why notable women? Because in each field there are so many women who contributed so much and are little known. I've never understood why Corita Kent , the pop-artist nun, isn't as famous as Andy Warhol, why Hetty Green , the Gilded Age value investor called both the "Witch of Wall Street" and the "Queen of Wall Street," disappears into history behind Benjamin Graham and his protege Warren Buffett. The problem I faced is that no one was seeing my bios, so I decided to make short videos or reels in hopes of increasing my reach. Creating the technical infrastructure for the reels on top of my existing system was fun and relatively straightforward. Each reel consists of a series of "beats," and Remotion turns those beats into a vertical reel, complete with on-screen text and royalty-free images & attributions pulled from Wikimedia, Flickr, or Library of Congress. For content, the beat generator relies on the knowledge base of validated facts that my system creates f

Originally published on PrepStack . Everyone's first RAG pipeline is the same four boxes: documents, chunk, vector DB, LLM. It demos in an afternoon and then quietly betrays you in production — stale answers, no relationships, no governance, and a model guessing from fragments. The fix is not a bigger vector index. It is to stop storing documents and start storing knowledge . That is Open Knowledge Format (OKF). To be clear up front, because the title is deliberately provocative: OKF does not kill embeddings. Vectors still do the recall. What OKF kills is blind chunking — slicing opaque documents into context-free fragments and hoping cosine similarity reassembles meaning. On Mattrx , a multi-tenant marketing-analytics SaaS (.NET 9 + Azure SQL + a Python FastAPI AI service), replacing blind chunking with OKF + a Context Engine took the assistant's hallucination rate from 18% to 3% and stale-answer rate from 11% to 1.5% . TL;DR Dimension Documents → chunk → vector DB (before) OKF + Context Engine (after) Unit of knowledge Opaque chunk of text Typed, governed knowledge unit Structure None — chunks are islands Metadata + relationships + schemas Freshness Snapshot, rots silently valid_until + live API refs Rules Buried in prose, ignorable First-class data the engine enforces Retrieval Top-k cosine Hybrid + vector + graph Multi-hop questions Unanswerable Answered via relationships Results after the rebuild: Knowledge base restructured into ~11,000 OKF units (Markdown + metadata + relationships + APIs + schemas + business rules). Hallucination 18% -> 3% ; faithfulness 0.96 ; answer-relevance 0.91 . Context tokens/call 14k -> 3.5k — structure lets the engine attach the right thing, not everything. Outdated-answer rate 11% -> 1.5% ( valid_until + metadata freshness). Multi-hop questions unanswerable -> answered via graph retrieval. Deprecated-plan recommendations recurring -> 0 (business rules enforced as data). The one mental shift: a chunk is a fragment of text with no id

I got tired of manually writing MCP tools for every REST endpoint I wanted to expose to an LLM. So I automated it. mcpgen reads an OpenAPI JSON or YAML file and generates a complete, ready‑to‑run MCP server in Python. 🔧 What it does Parses OpenAPI 3.0 / 3.1 specs Creates one MCP tool per endpoint (with snake_case names) Handles auth automatically (API key, Bearer, etc.) Outputs a clean, human‑readable Python script Zero runtime surprises – just mcp and httpx 🚀 Quick start bash pip install mcpgen mcpgen my-api.json -o my-mcp-server python my-mcp-server/server.py The generated server runs over stdio – ready to plug into Claude Desktop or any MCP client. 🧪 Real‑world test Recently a contributor added an OpenAPI 3.1 fixture (Xquik API) with lookupTweet and getUser endpoints. The tool generated the correct tools, including path parameters and x-api-key auth, on the first try. All 18 tests pass. It works. 🤔 Why you might want it If you’re building LLM agents that need to interact with APIs, mcpgen eliminates the boilerplate. You don’t have to write a single @app.tool() decorator by hand. It also makes it dead simple to experiment – change your API spec, regenerate the server, and you’re done. 📦 Links GitHub: JnanaSrota/mcpgen PyPI: pip install mcpgen MIT licensed, open to contributions 🙏 Feedback If you try it with your own API spec and something breaks (or works beautifully), I’d love to hear about it.

Anthropic's Claude Science is a workbench that gives scientists one environment to do computational research, saving them from the need to bounce between databases, pipelines, and tools.

A year in, National Design Studio delays plan to update government web standards.

Last week we introduced Upsun Dispatch™: a platform for the agentic software development lifecycle, where workflow is the primitive , not the agent. Today, prerelease is open. Starting July 1, a founding cohort of design partners gets early access. This is not a traditional beta. We are looking for engineering teams already running AI workflows and hitting the limits of what individual tools can do: teams who want to help shape what Upsun Dispatch becomes, not just use what we ship. Design partners get direct access to the core team, real input on the roadmap, and charter terms that reflect a genuine partnership rather than a vendor relationship. Apply at upsun.com/dispatch . Read the full announcement: Upsun Dispatch™ is now open for prerelease Starting July 1, 2026, Upsun Dispatch™ is open to a founding cohort of design partners.

I was taking a break from the AIE Workshops on Monday and stepped out by the food stands to check out the crepes. That's when I saw a line literally wrapping the entire length of the Moscone West windows looking out onto Fourth Street. I couldn't imagine what a several-hundred-person line was for, and when I went to ask, they told me it was for the Context Engineering Workshop. That sent me down a rabbit hole exploring and understanding and learning. So now, for you, I will share what I got. For the past couple of years, the AI world was obsessed with prompt engineering, aka the art of speaking to a machine. But as developers move from simple chatbots to complex autonomous agents, a new discipline has taken center stage: context engineering. Mike Swift ( @theycallmeswift ), CEO of Major League Hacking ( @mlhacks ) , gave me some critical background. He pointed me to Dex Horthy of HumanLayer (who is actually speaking later this week), who basically coined the term at the first AI Engineer World's Fair. Dex's core thesis, said Swift, is that "agents get bad after about 100,000 tokens," which represents roughly 10% of their total available context window. So context engineering is essentially managing an AI's working memory. Context engineering, Swift noted, is "managing how many times the loop goes around to how much you have to remember every time you do it." It is a counterintuitive concept for humans; the more we talk about a subject, the deeper our shared understanding becomes. But models work the opposite way. They lose focus as their context window fills up. For many developers, meticulously curating this working memory is a practical necessity. I sat down with Ben Halpern ( @ben ), founder in residence at MLH and co-founder of DEV, who told me that context engineering is the "latest frontier of the optimization point" where developers can leverage their expertise. Beyond just keeping models coherent, Ben pointed out that developers who are doing product work ma

You have seen this loop before. An agent starts a “simple” task, say scrape listings, refactor a repo, research a market, or whatever. It fails, it retries, it re-reads context, it apologizes and tries all over again. Twenty minutes in and the dashboard shows six figures of tokens and zero useful outputs or deliverables. The model did not misbehave on purpose. The orchestrator never had a hard budget gate with an ROI in mind. Skillware v0.4.0 ships a new skill for exactly that gap: monitoring/token_limiter . It lets you monitor and limit any agent’s token budget in real time — Gemini, Claude, OpenAI, DeepSeek, Ollama, custom Python loops, you name it. Same skill, same JSON, any runtime. What Skillware is in a nutshell Skillware is an open registry of installable agent capabilities . Each skill is a bundle: skill.py — deterministic Python ( execute() returns JSON) instructions.md — when the model should call the tool manifest.yaml — schema, constitution, issuer Tests and docs — shipped in the wheel You load by ID, adapt for your provider, call execute() on tool use. The model decides when , the skill decides how , predictably, every time. That split matters for budget control. You do not want the LLM guessing whether it is “allowed” to spend more tokens. You want a small, auditable function that answers: continue, warn, or stop. Meet the Token Limiter This skill is a budget gate , not a kill switch wired into OpenAI or Anthropic. After each model turn, your host loop passes cumulative usage. The skill returns one of three actions: Action Meaning CONTINUE Under the soft threshold — keep going WARN Approaching the limit (default 80%) — tighten scope FORCE_TERMINATE Hard ceiling hit — stop the loop Important nuance: the skill does not cancel API sessions or kill processes. It returns a structured decision. Your orchestrator must act on it. That is by design — Skillware skills stay portable and provider-neutral. No skill-specific API keys. No network calls.
