Credits
64 lessons draw on work by other authors. Each one carries its credit line under the lesson; this page collects them by source so you can see what each source contributes and where.
Each source shows its status: licensed (a licence covers it), permitted (the source allows this use, or the lessons only summarise its ideas in our own words) or being rewritten in our own words (the lessons stay up until their rewrite is published).
Draws on ideas from the third-party GenAI FDE Cost and Latency Optimization Playbook (Tobias Weissmann), summarised in our own words.
