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 | $0.03194 | $0.03194 |
| Opus 5.5 | $0.01278 | $0.01278 |
| Sonnet 5.5 | $0.00639 | $0.00639 |
| Haiku 4.5 | $0.00319 | $0.00319 |
Grade A, and why
OpenNOW 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.

Core Priorities
- Performance first.
- Reliability first.
- Keep behavior predictable under load and during failures, including session restarts, reconnects, partial streams, device loss, and graphics-surface recreation.
If a tradeoff is required, choose correctness and robustness over short-term convenience.
Active Product Scope
- The supported desktop product is the Qt 6 application in
opennow-qt/backed bynative/opennow-core/andnative/opennow-streamer/. - Interpret unqualified references to OpenNOW, the desktop app, the client, the stream view, or the streamer as referring to this Qt/native stack.
- Electron implementations, Node-based desktop shells, browser renderer processes, preload scripts, and Electron IPC are legacy or out of scope. Do not modify, restore, build, test, or copy architecture from them unless the user explicitly requests historical comparison or a migration task.
- Do not introduce Electron, an embedded web application, or a second desktop runtime to solve a Qt problem. JavaScript tooling may still be used for repository-only tasks such as localization validation; it must not become part of the desktop application's runtime architecture.
Repository Layout
opennow-qt/is the current OpenNOW desktop application. C++ shell/runtime integration lives insrc/, Qt Quick UI lives inqml/, packaging assets live inpackaging/, and Qt tests live intests/.native/opennow-core/is the Rust application core. It owns settings, credentials, NVIDIA/GFN account and session orchestration, catalog services, CloudMatch, diagnostics, and updates.native/opennow-streamer/is the in-process native NVST streaming workspace. Its focused crates own protocol, transport, platform decode/audio/input, the engine, and the C FFI consumed by Qt.locales/contains localization sources and generated Crowdin output. See Localization before editing.docs/contains the protocol, migration, acceptance, and streamer-comparison references.OpenNOW-Site/is a separate repository when present; do not modify it from OpenNOW tasks unless explicitly requested.
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.

OpenNOW AGENTS.md is an instructions file published in the GitHub repository OpenCloudGaming/OpenNOW (3,555 stars, last pushed 2d ago), licensed MIT. It adds 3,194 tokens to every session, about $0.0128 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.
