News for hackers. Stuff that matters.

You're right about the transparency. I am selling training data for iOS 26 - $19.99 for the bundle.

The post demonstrates a real problem (LLMs don't know iOS 26 exists) and offers a solution I created. The urgency is genuine - iOS 26 releases September 15 and developers are finding their AI tools useless for Foundation Models work. Some dev somewhere is praying they don't have to work through Labor Day weekend debugging Foundation Models without AI help. We're all now used to AI assistance - losing it for new frameworks hurts.

Regarding posting frequency - I posted about this in July when I first created it, now again 6 weeks later because the landscape paradoxically hasn't changed: Claude 4.1 and GPT-5 both released post-WWDC yet still don't know iOS 26.

The value proposition is straightforward: Aggregating and structuring iOS 26 documentation saves developers countless hours of searching and piecing together fragments. At $19.99, it's less than 15 minutes of developer time.

I appreciate the direct feedback.

The post could have been more upfront about the commercial aspect while still demonstrating the technical problem.

Web search helps but has drawbacks. For individual developers: each search adds latency and compute costs (API calls, processing, synthesis). The training dataset aggregates all that searchable information once, structures it for AI ingestion, then eliminates redundant processing. Instead of search-wait-paste cycles with inconsistent fragments, you get comprehensive framework knowledge instantly. This captures deeper insights (like constrained decoding architecture and ToolOutput patterns) that aren't easily found through search.

Front-loading the knowledge processing means every subsequent interaction is faster and lighter than triggering new searches.

This touches on an interesting concept - knowledge arbitrage - this information has a shelf life, once the SOTA LLMs know about iOS 26 my files turn into the Beta Max of training data.

Here's how i did it:

iOS 26 Launches Sept 15 – Even GPT-5 Doesn't Know It Exists

iOS 26 releases September 15. I asked every major LLM about it today.Prompt: "Without conducting any research or inference, what is iOS 26?" GPT-5: "iOS 26 does not exist within my training data" Claude 4.1: "I don't have any information about iOS 26" Gemini: "I cannot answer your question about iOS 26"They don't know it exists, let alone Apple Intelligence updates.Try asking for actual...

I created a new training dataset for stale SOTA LLMs

I ran into a common problem building with Apple's new iOS 26 Foundation Models framework. Every major LLM (GPT-4, Claude, Gemini) knows nothing about it due to training cutoffs.Rather than wait months for model updates, I spent 2 hours building custom training data:Research: Used Gemini's deep research to crawl all available docs, forums, GitHub repos, Reddit threads, YouTube transcripts....

The computational cost of corporate rebranding

Coke Classic, er, I mean HBO Max is Back!This got me thinking about how corporate rebranding creates unexpected costs in AI training and inference.Consider HBO's timeline: - 2010: HBO Go - 2015: HBO Now - 2020: HBO Max - 2023: Max - 2025: HBO Max (they're back)LLMs trained on different time periods will have completely different "correct" answers about what Warner Bros' streaming service is...

Exactly! We're in a transition period where technical knowledge exists but AI can't access it. This bridges that gap until models retrain. The methodology works for any new framework - Foundation Models just happens to be the current example.

I used AI research tools to systematically extract and organize Foundation Models knowledge from over 100 sites that wasn't in any training data. The value is in the methodology and validation, not just raw output.

LLM-Ready Training Dataset for Apple's Foundation Models (iOS 26)

https://rileyhealth.gumroad.com/l/bwoqe

I've been working with iOS 26 and Apple's new Foundation Models Framework. I realized every major LLM (GPT-4, Claude, Gemini) currently knows nothing about it—because training cutoffs predate its release.So I created a structured training dataset specifically for LLM ingestion. It covers: - Core API usage (SystemLanguageModel, LanguageModelSession, Tool protocol) - Advanced implementation...
