I think one of the hallmarks for success in product design in the age of AI is wrangling ever-increasing complexity and model capabilities, into products that are more accessible and easy to adopt. Example: Antigravity's "inbox" feature to drive and understand multi-agent state.
large monorepos break most language servers. we hit the same wall, dug into what was going on, and ended up with a 10x speedup from an embarrassingly small change. full write-up is here: nuanced.dev/blog/how-we-ma… anyone who has worked in a huge monorepo knows how critical…
It also seems vastly easier to think about sandboxing and permissions when dealing with TypeScript APIs instead of REST. I illustrated this in this talk I gave recently: youtube.com/watch?v=xUj4HQ…

👀 Animals have been assigned. Scheduled to print fall 2026! We have iterated on this with over 3k students (and continue to do so). We give our students access to the full draft as part of our evals course (link in bio).
if you're vibe coding refactors, you need @nuanced_dev. I recorded a demo (link ⬇️) showing a refactor in Claude Code with and without Nuanced MCP. Same refactor, same prompt, run twice. The results: - Nuanced is more accurate on the first go - 35% faster - uses 32% less…
We have done 2 cohorts and ~800 people have meaningfully engaged with the AI evals course. Hamel shared a bunch of testimonials with me yesterday. I was really astounded that they are not just generic testimonials; people mentioned very specific results and concepts. It seems…
Today, we're announcing our first hosted infrastructure product: pyx, a Python-native package registry. We think of pyx as an optimized backend for uv: it’s a package registry, but it also solves problems that go beyond the scope of a traditional "package registry".
Fall semester is starting, and many universities are rolling out AI engineering courses. If you teach an AI engineering course at your university, email me at [email protected] or DM me for a free copy of our 11-chapter, 166-page course reader to share with your…
Today we're launching Nuanced MCP for TypeScript, available to individual developers. 🚀 Developers kept asking for an MCP server they could drop into Claude Code/Cursor--so we built it. It gives AI a compiler-grade call graph for grounded edits and fewer tokens. Links to our…
As market usage of AI tools increases, the diversity of goals and intentions increases. As AI tools begin incorporating a “spectrum of autonomy” into their interaction design, Karpathy’s scenario here hints at another axis of “spectrum of effort”.
Two situations: 1 I wave a co-worker to my monitor to show them a file I have open. "Is this right"? 2 I sit down someone at a table. They have 2 hours to respond. This is an exam. The stakes are high. "Is this right?" The humans collaborator knows 1 vs 2. The LLM doesn't know…
GPT-5: "The model provided an ambiguous search string to replace" Me: dawg the function is right there. This is why we built Nuanced, so your AI can see the actual structure of your code, not just tokens. Call graphs. Symbol maps. Static analysis.
Nuanced provides compiler-grade context for AI coding. We just launched our explainer video: 📽️ youtu.be/674AwhMVoSE

Nuanced: compiler-grade context for AI coding
I prompted Claude Code to center a div and it had a meltdown. why? because your LLM is guessing with grep, not reasoning. I wrote about how programming languages are precise, but prompts aren’t. And how we fix that at Nuanced. (link below) 👇

Woot, Elixir's v1.18 type system found dead code, for free (no changes to code required):
Or if your net worth is over $100 million and your effective tax rate is < 25%, you sell some stock to get your effective tax rate to 25%. Why is anyone talking about jail?
Taxing unrealized capital gains might place Silicon Valley entrepreneurs like myself in jail. Udacity stock went up and down (on paper!), but at its "unicorn" prime I would not have been able to pony together the cash necessary to pay those taxes. Jail time for people who build?…
Cool job alert -- @aymannadeem is hiring founding engineers for her YC company Nuanced. They are working on a deep + hard problem at the center of AI and the future of trust on the internet, if you are passionate about either you should apply. ycombinator.com/companies/nuan…
