Compare two prompts
Shorter prompts often save more than model shopping alone.
A prompt token diff compares two prompts on token count and projected monthly dollars across models. It answers whether compressing a system prompt actually saves money. A shorter prompt that triggers longer completions can still cost more, because output tokens are often priced higher than input.
Use it in prompt-compression reviews. Keep temperature and tools identical when you compare production prompts.
Diff two prompts on token count and projected monthly dollars. Ideal for prompt compression reviews and “does this system prompt pay for itself?” checks.
Paste prompt A and prompt B, choose models and traffic, then run the diff. Read token and monthly dollar deltas. Tokenization is local. Catalog prices are list rates. The models are not called.
Paste prompt A and prompt B.
Choose models and traffic assumptions.
Run the diff to see token and $ deltas.
Completion tokens often cost more than input tokens. Cutting 200 input tokens that causes 400 extra output tokens can raise the bill. Dollar diff on your real traffic is the decision, not a raw token count.
Use LLM Cost Calculator to size a prompt pack against several models. Use Prompt Token Diff when the question is “does this rewrite of the same prompt pay for itself?” Same traffic, two texts, one table.
A prompt token diff compares two prompts on token count and projected monthly dollars across models. It answers whether compressing a system prompt actually saves money. A shorter prompt that triggers longer completions can still cost more, because output tokens are often priced higher than input.
Output-heavy models price completion tokens higher. A shorter prompt that triggers longer answers can still cost more.
