Models and prices checked .
Short answer
Claude Haiku 5.5 is the least expensive model that can run it: one run counts as 1 everyday message, plus 15 Claude Haiku 4.5 messages from the month. 19 of the 19 models can run it; each one's price is below.
The prompt
Research [question] and write a report I can share: a one-paragraph answer first, then the evidence with sources, where the sources disagree, and what's still unknown.
Replace the parts in [brackets] with your own. It's in the prompt library with the others.
What it needs from a model
A research report (paid plans): 15 Claude Haiku 4.5 messages (Standard) or 75 Claude Haiku 4.5 messages (Deep), on top of the message that starts it.
Which models, and what one run counts as
Start with the least expensive model that can run it, and move up only when the answer isn't good enough: the next model sees the whole chat.
| Models | One run on a paid plan | Runs on Pro |
|---|---|---|
| Claude Haiku 5.5, GPT-6 Luna, GLM 5.3 Flash, and DeepSeek V4.1 FlashEveryday model: from the daily count | 1 everyday message, plus 15 Claude Haiku 4.5 messages from the month | 16 a month |
| Mistral Large 4, DeepSeek V4 Pro, Gemini 3.8 Flash, Claude Haiku 4.5, GLM 5.3, and Grok 4.7 | 1 message of the model, plus 15 Claude Haiku 4.5 messages | 15 a month |
| Claude Sonnet 5.5, Claude Sonnet 5, GPT-6.1 Sol, GPT-6 Sol, Gemini 3.1 Pro (preview), and Kimi K3 | 1 message of the model, plus 15 Claude Haiku 4.5 messages | 14 a month |

Every limit is published. Paid plans also have a monthly fair-use limit on AI cost: Pro $7.50, Max $20, Ultra $42, Studio $85. Using every message on your plan at typical sizes stays under it; very large messages and heavy research use it faster. Every limit, explained.
What a report counts as
Researches a question on the web in the background and writes a cited report you can open and download. Standard runs about 10–20 searches; Deep uses Perplexity's deep research.
| Depth | One report |
