Variant A
0tokContext0.0%
Variant B
0tokContext0.0%
How to use
- Pick one target model so both panes use the same tokenizer and context window.
- Edit A and B independently (text or ChatML). Token bars update per side.
- Use Swap to flip variants, or load from / send a side to the Editor.
- Copy or download ChatML JSON for each side before shipping to an API.
FAQ
Do A and B share one draft with the Editor?
No. Compare keeps its own localStorage draft. Use “Editor → A/B” or “A/B → Editor” to transfer intentionally.
Why is the model shared?
A fair A/B token comparison needs the same encoding and context window. Edit each side’s content independently.
What does Copy ChatML export?
ChatML mode exports the message array. Text mode wraps the plain text as a single user message JSON payload.
