Across 144 repeated calls, +Jev reached 100.0% binary F1 with stable labels on all 48 cases. Compared with +Luna on the same calls, Jev was 4.8x faster at p50, 4.7x faster at p95, and +11.1x cheaper, while improving joint accuracy from 71.5% to 95.8%. + +A reasonable first canary policy is a symmetric `0.80` confidence gate: this +accepted 93.1% of calls at 100.0% binary accuracy in this run and would send the +remaining 6.9% to the existing classifier. Keep the deterministic source, +reply, and seeking-work filters, plus the production output validator, in front +of any model decision. Validate next on a sanitized, held-out sample of +historical posts and then with labeled live shadow traffic before raising +coverage. The OpenRouter Decisions route is currently under `/api/alpha`, so +pin and monitor its request/response contract before production use. + +Use Jev only for the binary decision initially. Its only errors were two +four-way posting-type classifications: it labeled a closed role and a +seeking-work post as `part_time`, while still correctly rejecting both as not +contractor-friendly. If the four-way type is operationally required, add an +explicit current-job-post gate or retain the existing normalizer for that +field. + +Luna's result measures the actual production prompt, schema, effective request +options, and normalizer, not unconstrained model capability. It still produced +41 binary false negatives across 144 calls, concentrated on contract and +part-time alternatives normalized as `full_time` or `unknown`. Improve that +contract before using this result to make broader conclusions about Luna. + +No production classification path was changed by this evaluation. + +## Results + +| Profile | Successful calls | Contractor F1 | Posting accuracy | Joint accuracy | Stable cases | Latency p50 / p95 / max | Input / cached / output tokens | Cost | +| --- | ---: | ---: | ---: | ---: | ---: | ---: | ---: | ---: | +| heuristic | 48/48 | 79.2% | 62.5% | 62.5% | deterministic | 0 / 0 / 1 ms | 0 / 0 / 0 | $0.000000 | +| jev | 144/144 | 100.0% | 95.8% | 95.8% | 48/48 | 428 / 616 / 3292 ms | 73650 / 0 / 10590 | $0.003093 | +| luna | 144/144 | 60.2% | 71.5% | 71.5% | 44/48 | 2046 / 2873 / 4602 ms | 56109 / 0 / 19221 | $0.034287 | + +The heuristic is local code, so its latency and zero cost are not an API-to-API comparison.

It deliberately over-represents negation, commercial uses of the word `contract`, non-posts, and prompt-injection-like text; it does not estimate live HN prevalence. +- Golden labels are exact and scoring is deterministic. No model judges another model. +- The experiment applies the classification-harness pattern described in LangChain's [Jev harness article](https://www.langchain.com/blog/building-a-harness-with-jev). +- The heuristic and Jev observations were captured at `2026-09-20T19:57:45.070955+00:00` on revision `3853befc65ddb6e37840084858a64fdb6204e5cf`. Luna was rerun at the report-assembly time on the harness revision above after its request options were aligned with production; the aggregate tables were then recomputed from both normalized observation sets. +- Jev uses OpenRouter's `/api/alpha/decisions` endpoint and the pinned [`typesafe/jev-1.13`](https://openrouter.ai/typesafe/jev-1.13/) request ID. The resolved dated snapshot is retained in the JSON observation report. +- The Luna baseline uses the production job-lead prompt and schema through direct OpenAI. A preflight through OpenRouter returned HTTP 403 under provider terms, so the report does not present an unsupported route as a benchmark failure. +- Luna's self-reported classification confidence is retained as diagnostic metadata, but it is not treated as a calibrated contractor probability or used in the Jev confidence-gate analysis. +- Latency includes successful and failed calls. Jev cost is provider-reported. For GPT-5.6 Luna only, missing cost is estimated from successful retained token usage at the official [$0.20/M input, $0.02/M cached input, and $1.20/M output rates](https://developers.openai.com/api/docs/models/gpt-5.6-luna); missing cost for a custom `--llm-model` or any profile with unpriced failed calls remains unavailable. +- Raw observations are generated under the gitignored reports directory; this Markdown summary intentionally excludes provider payloads and secrets. diff --git a/.env.example b/.env.example index 64bc9459..da45ad38 100644 --- a/.env.example +++ b/.env.example @@ -222,6 +222,18 @@ AGENT_REASONING_API_KEY= JOB_LEAD_CLASSIFIER_ENABLED=true JOB_LEAD_CLASSIFIER_MODEL= JOB_LEAD_CLASSIFIER_TIMEOUT_SECONDS=8.0 +# Optional Jev canary.
