Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Pressbooks

  • Self-hosting is free in licence terms only; it requires WordPress multisite administration, upgrades and backups, which is a real staff cost most institutions underestimate.
  • Professional print PDF output depends on a commercial rendering engine that is licensed separately, so the genuinely free self-hosted route produces web and EPUB output but not press-quality print.
  • Design control is limited to the supplied themes unless someone writes custom CSS, so books tend to look recognisably like Pressbooks books.
  • There is no distribution, no ISBN service and no retail channel, so it produces files and web pages but plays no part in selling anything.
  • The editing experience inherits WordPress conventions, and authors working on long or heavily structured manuscripts find it slower than a dedicated writing application.

Together AI

  • Free tier limits not clearly specified in pricing documentation
  • Pricing varies significantly by model and use case
  • Requires account setup for production access
  • Batch API discounts apply only to non-urgent workloads

Answered from the vendors’ own pages

Pressbooks: Can I sell a book made in Pressbooks?

You can sell the EPUB or the printed book through any distributor, but Pressbooks itself provides no ISBN, no storefront and no distribution.

Together AI: What are Together AI's highest model prices?

Serverless inference pricing ranges from free for base models up to $4.40 per 1M input tokens for premium models. Video generation costs $0.14 to $3.20 per video depending on resolution.

Together AI offers up to 83% savings compared to commercial alternatives when using their Provisioned Throughput option with reserved capacity.

Source
