Which Claude, When

Which Claude, When is the complete 2026 guide to two problems every Claude user runs into: which model to use, and how to stop hitting your limits. If you never quite know whether to reach for Haiku, Sonnet, Opus, or Fable, this 100-page premium guide gives you a clear decision framework to match the right model to any task. And if you keep running out of usage before you are done, it delivers exhaustive, practical tactics to stretch your limits across claude.ai (chat), Claude Code, and the API. Inside you will find deep dives on each model, a quality-speed-cost mental model, context-management tactics (the single biggest lever), the token math of everyday work, model-routing and escalation strategies, and cost control for teams and heavy users. It is rounded out with 16 before-and-after case studies, cheat sheets, a 30-day optimization plan, an FAQ, and a glossary. Built for 2026, with every exact number clearly dated and the durable method underneath, so it stays useful as the model lineup evolves. Written for everyone from casual users to developers and teams. Premium PDF, A4, with a clickable navigable table of contents, PDF bookmarks, and fully searchable text. Instant access after purchase, lifetime, for personal use. Independent educational product by NoCodeNation.
