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 | $0.00215 | $0.00215 |
| Opus 5.5 | $0.00086 | $0.00086 |
| Sonnet 5.5 | $0.00043 | $0.00043 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
pi-tinker copilot-instructions.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.
What it actually says
pi-tinker repository instructions
- Read
AGENTS.mdanddocs/coding-agents.mdbefore changing workflows. - Pi is the primary UI; shell-based agents can run
node scripts/agent-cli.mjs <subcommand>. - Use official Tinker SDK, Tinker Cookbook, and
tml-renderers; do not create a parallel training framework. - Keep generated Python and data files normal, editable, and inspectable.
- Default to
thinkingmachines/Inkling; preserve support for explicitly selected alternative Tinker models. - For Inkling, use Python 3.11+, Tinker SDK 0.23+, and
tinker-cookbook. - Match baseline and checkpoint reasoning effort. Default Inkling SFT/eval effort is
0.9unless the user deliberately changes it. - Never trigger API usage or training without explicit approval. Smoke-test for two steps before scaling.
- Use
@trigger.dev/sdkv4 patterns if unrelated Trigger.dev code is encountered; never use deprecatedclient.defineJob.
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.
