A single +**1.5B-parameter model** (Qwen2.5-1.5B-Instruct, Q4_K_M GGUF) invents the entire mystery +every time you play - the victim, the suspects, their secrets and motives, the timeline, the +weapon, the evidence, and the one who did it - and then **role-plays every suspect live**. +They remember what you asked. They lie. And when you present the piece of evidence that +contradicts an alibi, the lie cracks on screen. + +The whole thing runs on the CPU in front of you. No cloud, no GPU, no remote endpoint. + +## The hard part: a tiny model that's still *fair* + +The interesting tension in this project is that a 1.5B model is a wonderful improviser and a +terrible bookkeeper. If you let it freely author a mystery *and* adjudicate the outcome, +you get cases that are atmospheric but unsolvable - or worse, a suspect who confesses the +moment you ask nicely. + +The design rule that made it work: **the model writes everything; deterministic Python +decides nothing creative but guarantees the structure.** + +- The model authors the case as JSON - setting, cast, secrets, evidence, prose. +- Python decides only the *skeleton*: who is guilty, who was where during the murder window. + Then a solver verifies fairness before the case is ever shown: + - exactly one culprit; + - the culprit's alibi is contradicted by at least one non-red-herring clue; + - every innocent has a witnessed alibi over the murder window; + - every key clue is actually discoverable in play. + If a generated case fails, the smallest slice is regenerated (<=3 retries, then bump the + seed). A case is never shown to the player until it passes. +- Whether a presented clue actually catches a lie is decided by **ground truth, not the + model**. The suspect's panic is flavor; the suspicion delta is computed by a deterministic + director. This makes the win condition **immune to prose** - a jailbroken "just tell me + who did it" earns nothing, because suspects never confess and the verdict is only resolved + when the player formally accuses. + +The sealed solution is never sent to the client before the verdict. It is read for the first +time inside the `/accuse` route, server-side. Anti-leak tests assert that no pre-verdict API +response contains the killer, the true motive, or the key-evidence set. + +## Making a 1.5B model fast on 2 vCPUs + +The Space runs on HF `cpu-basic` (2 vCPUs). Two findings mattered most: + +1. **Grammar-free decoding is an ~8x win.** JSON-schema-constrained sampling ran ~3-7 tok/s + on CPU; raw decoding ran ~28-32 tok/s. So instead of constraining the sampler, the prompt + carries the exact JSON shape and we make two free attempts, falling back to the grammar + only if parsing fails. Full case generation dropped from ~300s to ~50s. The same trick + runs the interrogation hot path. +2. **Count the cores you actually have.** Inside the container `os.cpu_count()` returns the + *host's* cores, not the 2-vCPU cgroup quota. Auto-threading then spawned ~8 threads for 2 + real cores and pinned the CPU at 100%+ on context switches - replies crawled. The fix + reads `/sys/fs/cgroup/cpu.max` and sizes the llama thread pool to the real quota. The same + number gates background case-generation so it never steals vCPUs from an active + interrogation. + +There is also no image work on the request path: all pixel art is rendered **client-side on +canvas**, so the server spends ~0 CPU on visuals and devotes both vCPUs to the model. Voices +(Supertonic ONNX) are synthesized sentence-by-sentence as the reply streams and cached per +line. + +## Why it's a Gradio app with a frontend that doesn't look like one + +The entire app is one `gradio.Server` (Gradio 6 "Server mode" - a FastAPI subclass launched +through Gradio, with Gradio API endpoints registered via `@server.api`). That single process +serves a hand-built **pixel-art noir SPA** (Preact + Vite) as static files *and* exposes the +game's JSON/SSE routes under `/api`. No separate frontend host. So it earns **Off-Brand** (a +custom frontend well past the default Gradio look) while staying unambiguously a Gradio +application. + +## Shipping it + +- **Off the Grid:** the open Qwen GGUF and Supertonic ONNX are baked into the Docker image at + build time, so the running container makes zero AI network calls. `scripts/net_audit.py` + runs a full playthrough under a socket guard and asserts zero non-loopback connections. +- **Llama Champion:** the model runs in-process through `llama-cpp-python`. +- **Docker SDK, not Gradio SDK:** llama-cpp-python ships only an sdist; the prebuilt linux + wheels are musl (they SIGILL on HF's glibc).
