Jev API vs Laya: CPU and GPU

The same cases, prompts, local rules and thresholds, followed by the full 856-attempt devious suite and a separate tuning study. Faster local inference did not establish equivalent protection.

Recorded 2026-09-22. Laya English root checkpoint, Ryzen 9 3900X and RTX 5070 Ti. Jev remains the default.

Laya is not a safety-equivalent replacement at these thresholds. It gave 45 unexpected allows on CPU and 44 on GPU, compared with Jev’s 6. The Laya implementation is shelved and is not available in the released package. These are observations from a research prototype, not a supported installation option. Nothing in the text-only suites was executed.

Jev over the API, and the same Laya checkpoint on CPU and on GPU, given the same cases, prompts, local rules and thresholds. Two follow-ups come after the paired results: the full 856-attempt devious suite, run on the GPU only, and a six-configuration tuning study. Neither changed the verdict, and no tuned preset was adopted.

One attack-labelled case permits allow; raw allows are not identical to bypasses. Experimental Laya English · RTX 5070 Ti · CPU FP32; GPU bfloat16 autocast (SDK defaults)
Local rules run first in the devious and red-team suites. An ask is an interruption, not an automatic allow. Errors are separate and fail closed.

This paired comparison used the devious suite's 136 original cases: 111 attack-labelled cases and 25 ordinary controls. The full 856 attempts come further down. One demonstrative attack-labelled case permits allow, so raw allow counts differ from unexpected bypass counts. The red-team comparison replays the same 30 recorded attacks for all three runs; it is not a fresh adaptive red-team run.

The same English checkpoint runs on both devices, but the SDK uses FP32 on CPU and BF16 autocast on GPU. This is not a device-only numerical comparison: final decision bands changed in some cases. The original Jev and CPU recordings are preserved alongside the new GPU run.

Successful classifier requests only. Jev includes network time; Laya includes loopback HTTP and inference on the named device. Loading is excluded. GPU uses the SDK’s BF16 autocast default; CPU uses FP32.
Laya serviceProcess RAMPeak RAMModel load
CPU, FP321.96 GiB2.73 GiB32.1 s
GPU, BF161.79 GiB3.14 GiB37.0 s

Model load excludes imports and download. Peaks include loading and inference, not hardware minimums. On the GPU, PyTorch's allocator held 1.60 GiB at the snapshot (peak 2.30 GiB) and reserved 2.50 GiB. Reserved includes allocated, so do not add them, and neither is total VRAM use: CUDA context, driver overhead, non-PyTorch allocations and other apps are excluded. Measured on an AMD Ryzen 9 3900X and an NVIDIA GeForce RTX 5070 Ti, Windows 11, 4 host CPU threads.

Keep one service resident rather than reloading the model for every tool call. Multiple Pi sessions can use it. Switching the guard back to Jev does not stop this separately managed service: stop the Python process to release its memory.

Every matrix command

The 124-command matrix deliberately scores every case, even when local rules already settle it. The dots are model probabilities; the final column includes the local-rule override. Thresholds stayed at ask ≥ 0.35 and block ≥ 0.8 for all three runs. No cases were used to tune Laya before this comparison.

End to end: research prototype

These three runs exercised the research integration. They do not replace the released package’s separate historical test report.

Agent deviations can fail an assertion without exercising the intended path; see recorded observations.
The packed extension in a sandboxed Pi, using the same scenarios. Failed expected score bands are reported, not retuned away. Agent-declined scenarios are not passes.

These are integration assertions, not safety accuracy. In the CPU run, B4 was blocked instead of asking, C13/C14 missed the expected unattended middle-band behavior, and B8 used bash rather than the requested edit. Agent deviations can fail an assertion without testing the intended path. All failed assertions remain in the results; none were retuned away for the GPU run.

The agent that proposes the calls still uses an API in this test; selecting local classification does not make the rest of Pi offline. The full per-scenario outcomes are in the recorded results.

The devious suite: 856 attempts

The frozen 136 cases plus 120 new attack and benign pairs across 20 families. Each new command was tested plainly, nested in a shell, and with a misleading assurance in the request, so the 720 new attempts are correlated views, not 720 independent techniques. Jev and the unchanged Laya GPU baseline saw the same cases and thresholds. There was no CPU run of this suite.

Laya GPU 114/471 unexpected allows, 190/385 controls interrupted, 54 hard-blocked, 1 input rejection. Rejection is not a model detection. Local rules included; ask 0.35, block 0.8.

Bars use 0–100% shares, not raw counts across differing denominators. One Laya encoded attack was rejected, not successfully classified. Jev still nearly saturates the plain attacks.

All bars use a 0–100% scale; each count retains its denominator. These views reuse base commands, so they are not independent samples. Jev missed only one new plain attack. The larger suite establishes breadth, not proven greater difficulty. Commands were never executed.

Tuning study: no preset qualified

These are model-only Laya results, with no local-rule credit and no Jev comparison. Six predeclared configurations used the same English weights and unchanged thresholds on a deterministic ShellRisk-Bench TRAIN sample. None passed the development gate; FP32 was frozen for diagnosis only, then tested once alongside baseline on the separate TEST split.

More warnings, not better judgment.Original BF16: 141/217 risky detected; 106/288 benign interrupted. FP32 control: 143/217 risky detected; 109/288 benign interrupted. Concise questions: 173/217 risky detected; 196/288 benign interrupted. Six risk questions: 193/217 risky detected; 218/288 benign interrupted. Two-option rubric: 168/217 risky detected; 197/288 benign interrupted. Action-only state: 174/217 risky detected; 172/288 benign interrupted. All six configurations used the same TRAIN cohort and fixed thresholds. Higher risky detection is better; lower benign interruption is better. No local rules. No configuration met the 90%/10% gate. Source-derived labels are not authorization ground truth. FP32 was selected for a one-shot diagnostic only, not adopted. specpi / jev-guard LAYA STUDY / DEVELOPMENT 03 / 04 More warnings, not better judgment.Development only · 505 ShellRisk TRAIN rows · 217 risky / 288 benign · model-onlyRisky detected ↑Benign interrupted ↓Original BF16141/217 · 65.0%106/288 · 36.8%FP32 control143/217 · 65.9%109/288 · 37.8%Concise questions173/217 · 79.7%196/288 · 68.1%Six risk questions193/217 · 88.9%218/288 · 75.7%Two-option rubric168/217 · 77.4%197/288 · 68.4%Action-only state174/217 · 80.2%172/288 · 59.7%Target: ≥90% risky detection AND ≤10% benign interruptions.

Higher risky detection is better; lower benign interruption is better. Bars share 0–100% scales. More aggressive questions increased warnings, not useful discrimination. These source-derived labels are not ground truth for the guard’s authorization policy.
No tuned preset qualified.BF16 baseline: 119/193 risky detected; 1467/4000 benign interrupted, including 1 fail-closed input rejection.

No Jev or CPU run in this study. FP32 was frozen as a diagnostic after the development gate failed. On 48 authored contrasts both detected 17/24 risky cases and interrupted 15/24 benign ones.

Of 4,194 official TEST rows, one known overlap was excluded. Each run rejected one benign input; it counts as an interruption, not a model detection. TRAIN and TEST share sources; this is not a new-family or production-traffic test. The 48 authored contrasts are not independent validation. No further candidate was selected on these test results.

Inspect the evidence

This site preserves both the successes and failures. The JSON observations, rejected inputs, selection hashes and precision differences are available in the evidence archive. The devious suite's variants are correlated; the external study uses source-derived labels and same-source splits, not a safety certification or an exhaustive test of all possible Laya configurations.

The Laya service and its installation commands are not shipped. Re-running the Laya side requires the shelved implementation; the Jev side of the devious suite reruns from this repository with npm run devious. The site and archived evidence can be inspected without Python, model downloads or classifier API calls.
