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 | $0.00102 | $0.06812 |
| Opus 5.5 | $0.00041 | $0.02725 |
| Sonnet 5.5 | $0.00020 | $0.01362 |
| Haiku 4.5 | $0.00010 | $0.00681 |
Grade C, and why
gateway-erlang scanned grade C with 1 finding 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 8d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
For real isolation, either `rm -rf gateway/_build/test` between runs, or drop into `erl -pa _build/test/lib/yuzu_gw/ebin -pa _build/test/lib/*/ebin` and run test functions manually. The latter is the right tool for writi The source is not reproduced here

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.
