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 | $0.00139 |
| Opus 5 | $0.00000 | $0.00069 |
| Sonnet 5 | $0.00000 | $0.00028 |
| Haiku 4.5 | $0.00000 | $0.00014 |
Grade A, and why
new-service 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 7d 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
Help me create a new service for the Blackfish platform.
The service name is: $ARGUMENTS
Guide me through creating:
- Service class in
lib/src/blackfish/server/services/extendingBaseService - API routes in
lib/src/blackfish/server/asgi.py - CLI commands in
lib/src/blackfish/cli/services/ - Frontend route in
web/src/routes/{service-name}/(registered inweb/src/router.jsx) - Tests for the new service
First, examine the existing services (text_generation, speech_recognition) to understand the patterns, then create the new service following those patterns.
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.

new-service is a command published in the GitHub repository princeton-ddss/blackfish (24 stars, last pushed 11d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 139 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 2026-09-01.
