Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00194 |
| Opus 5.5 | $0.00000 | $0.00078 |
| Sonnet 5.5 | $0.00000 | $0.00039 |
| Haiku 4.5 | $0.00000 | $0.00019 |
Grade A, and why
PP: Deep Research scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Overview Use Perplexity deep research mode for the most comprehensive and thorough investigation.
Features
- Most comprehensive research mode
- Extensively explores multiple sources and perspectives
- Takes longer but provides the most thorough answers
- Best for academic research, market analysis, and complex investigations
Steps
- Use
mcp__perplexity-mcp__researchtool with the user's query. - Set
mode: "deep research"explicitly. - Do NOT set
modelparameter (deep research mode does not accept model). - Set
language: "zh-CN"for Chinese responses. - Present the results with detailed analysis and sources.
Query: $ARGUMENTS
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

PP: Deep Research is a command published in the GitHub repository escapeWu/perplexity-ai (177 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 194 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
