New feature on @ChapterPal: the reader can now add a quiz on demand and choose what content it should cover. Previously, quizzes could only be created for the entire chapter by asking a multi-agent system to identify the topic to test and the places to put the quizzes. Some users wanted more quizzes and more granular ones. Now the user can test themselves as often as they feel as they progress in the reading. ChapterPal is without a doubt the best app to learn from scientific literature. AI is there to unblock you when you are stuck and to challenge you to test your understanding. The *active reading* approach, where the reader decides when to reveal the content and when to ask questions, blurred terms that prevent superficial skimming, highlights and note-taking, all this provably contributes to better retention.

The syllabus further explores deep learning through the lens of robust uncertainty estimation, out-of-distribution detection, and anomaly identification, ensuring learners can distinguish between reliable model outputs and unexpected edge cases. The curriculum concludes with advanced methods for model interpretability and feature attribution, providing the diagnostic tools necessary to audit model logic, build stakeholder trust, and fulfill essential production readiness standards. chapterpal.com/curriculum/fcf… Use the Subscribe button to receive email updates to this curriculum.

Several @ChapterPal users mentioned to me that they use Obsidian for notes, and they asked how to move their highlights, annotations, and Q&As from ChapterPal to Obsidian. Unfortunately, Obsidian doesn't have an API, so I showed a couple of screenshots to Codex today, and now ChapterPal has a new Obsidian-like Notes feature. The user can create beautiful notes from their highlights/annotations/Q&As they generate when reading a paper or a book chapter. They can even use AI to combine several messy highlightings or annotations into a single coherent note. Then, of course, these notes can be downloaded straight into the user's offline Obsidian vault. This feature was a single-day work. All important Obsidian features are already implemented, including the graph view, backlinks, hotkeys, and non-standard markdown commands. Any volunteers familiar with Obsidian to test ChapterPal's Notes and send me feedback on what isn't working or what's missing?

A new curriculum on @ChapterPal: Prep reading for the model serving and inference interview This curriculum provides a comprehensive technical foundation for understanding the architecture and deployment of modern machine learning models, specifically focusing on the lifecycle of large language models (LLMs) from foundational design to high-throughput inference serving. Learners will first engage with the Transformer architecture before transitioning to system-level optimizations, including custom compiler frameworks like TVM and Triton, memory-efficient attention algorithms such as FlashAttention and PagedAttention, and sophisticated serving strategies like disaggregated prefill-decode architectures and speculative decoding. Furthermore, the curriculum addresses practical deployment challenges such as hardware-aware quantization techniques (LLM.int8(), SmoothQuant, GPTQ, AWQ) and the efficient multi-tenant management of fine-tuned adapters using methods like S-LoRA, ultimately equipping engineers with the expertise to build scalable, low-latency, and cost-effective model serving infrastructures.

If you are an author or just write regularly and Markdown is your system of choice, try my @ChapterPal platform in the Editor mode. It's a WYSIWYG Markdown editor that I've built for myself, and I've added lots of cool AI features that simplify writing and achieve high writing quality with minimal effort. It supports individual articles and multi-chapter books and generates reference numbers automatically, with support for cross-chapter references. If you try it, please send me your feedback. Here's just one example of what ChapterPal's editor can do. In the right screenshot, there's the "Link" option. When you type LINK between two paragraphs, then select these two paragraphs and then choose "Link," the AI will replace LINK with a paragraph or a sentence that logically links the two selected paragraphs so that the reading flow is smooth.
