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 | $0.03672 | $0.03672 |
| Opus 5.5 | $0.01469 | $0.01469 |
| Sonnet 5.5 | $0.00734 | $0.00734 |
| Haiku 4.5 | $0.00367 | $0.00367 |
Grade A, and why
Lesma 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 2mo 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.

This file gives future agents (and humans) a quick reference for how the Lesma compiler works, how to build it, and how to validate changes.
What Lesma is
Lesma is a compiled, statically typed, imperative, object-oriented language that targets LLVM. The compiler is C++23 and uses LLVM for code generation, optimization, JIT, and object-file emission. The standard library is written in Lesma (.les files in src/stdlib/).

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.

Lesma AGENTS.md is an instructions file published in the GitHub repository alinalihassan/Lesma (20 stars, last pushed 6mo ago), licensed MIT. It adds 3,672 tokens to every session, about $0.0147 per session on Opus 5.5. 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.
