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 | $0.22890 | $0.22890 |
| Opus 5.5 | $0.09156 | $0.09156 |
| Sonnet 5.5 | $0.04578 | $0.04578 |
| Haiku 4.5 | $0.02289 | $0.02289 |
Grade B, and why
omnisim AGENTS.md scanned grade B with 2 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 2d 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.
Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

AGENTS.md — Running OmniSim as an AI Coding Agent
This file is for AI coding agents (Claude Code, Codex, Cursor, custom agent harnesses) working inside a fresh clone of OmniSim. It tells you exactly what to do to get a demo running. The conventions below match the AGENTS.md open standard, and tools that respect that standard will load this file automatically.
If you are a human, this file also works as a quick "what does OmniSim do and how do I run a demo" cheat sheet — the README and the Developer Quickstart have the long form.
OmniLink access policy, 2026-09-22: The owner requires an OmniKey for every OmniLink AI experience, including Free. Do not restore keyless chat, automatic local-model selection, or basic-command fallback after connection errors. Ordinary OmniSim typed controls and Stop remain available. Use the current setup guide; it supersedes older keyless instructions in this file. Customer-facing pages must not reveal architecture. Cost comparisons are ALLOWED again (owner, 2026-09-27: cost is a competitive advantage — mention it): quote a measured benchmark with its conditions (workload, model, what was counted) and link the evidence, but never say or imply the AI layer itself costs nothing — an OmniKey and the user's own model-provider key are still required.
0. For agents: read this first (60 seconds)
Call it OmniSim, and know what it is for. The simulator is OmniSim — its own product, with substantial additions over the upstream Webots engine it forked from (URDF importer, agent-facing HTTP harness, capture / cinema pipeline, OmniLink agent runtime, omniworld procedural world generator, RL pipeline, CUDA granular-physics, multi-instance parallel runs, OmniSim Wire Protocol). When you talk to the user about the running simulator, the binary, the env vars, the URL scheme — say OmniSim. Use "Webots" only when explicitly referring to upstream (the GitHub repo, the file-format syntax inherited from VRML, the original PROTO conventions).
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.

omnisim AGENTS.md is an instructions file published in the GitHub repository omnilink-tech/omnisim (192 stars, last pushed 2d ago), licensed Apache-2.0. It adds 22,890 tokens to every session, about $0.0916 per session on Opus 5.5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
