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 | $0.02377 | $0.02377 |
| Opus 5.5 | $0.00951 | $0.00951 |
| Sonnet 5.5 | $0.00475 | $0.00475 |
| Haiku 4.5 | $0.00238 | $0.00238 |
Grade A, and why
nagi-bench AGENTS.md 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.
How it starts
The opening of the file, as written. The whole thing — 205 lines — stays where its author put it; the contents beside it link to each section on GitHub.

What this repo is
The public data repo: community-contributed one-shot LLM eval artifacts. You add a model's raw output for a case; the site renders it verbatim. This repo holds data only — no site code, no build of the page you see.
A contribution is exactly two files
- The artifact — the raw model output, dropped at
outputs/<artifactDir>/<case-id>.<ext>(e.g. a single-file.htmlor.svg). - The registration —
models/<model-id>.jsondeclaring it.
Do not touch anything else. In particular:
- Do not edit
README.md/README.en.md. The Registry tables are generated frommodels/*.jsonand synced automatically after merge. Hand edits are overwritten. - Do not edit
cases.json. Cases are maintainer-owned.

Naming rules
- The filename IS the entry id — lowercase letters, digits and dashes only
(
deepseek-v4-flash-reasonix). It is the stable voting key and the defaultoutputs/folder, so name it after the model, not the harness. Bad:reasonix-reasonix-max. Good:deepseek-v4-flash-reasonix. artifactDirmay be one or two dash-case segments (deepseek-v4-flash/reasonix-max); set it when several entries share a model folder. Leave it out to default to the id.
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.
