The site is https://lmjtfy.fun, bare (the owner's domain, on Cloudflare, 2026-10-03). It began at https://lmjtfy.deizel.workers.dev, which stays on, and www.lmjtfy.fun is attached, only so the Worker can send their visitors, link previews and clones on with a permanent redirect (moved in src/lib.rs). No per-version preview addresses beside them.

A pinned model: jev-protocol refuses aliases, because the answers behind an alias change without a change here.

22JEV_MODEL = "jev-1.13.0"

The LLM that writes Jev's questions: the cheapest candidate that passed every case of tools/eval (2026-10-02: 14/14, about 16 neurons a call; the one cheaper model, granite-4.0-h-micro, passed 11). Rerun the eval before changing it.

27LLM_MODEL = "@cf/qwen/qwen3-30b-a3b-fp8"

The most all visitors together may spend on Jev in a UTC day, in dollars. The LLM's own budget is not set here: it is Workers AI's free allocation (llm::FREE_NEURONS_PER_DAY). A dollar is about 25,000 requests at $0.00004 each (the owner, 2026-10-02: "they will never hit it anyway").

32JEV_DOLLARS_PER_DAY = "1"

Workers AI. There is no local emulation: wrangler dev calls the real models on the real account, so it needs the account's token (lmjtfy-wrangler, from the devshell).

37[ai]
38binding = "AI"

The day's budgets, shared by every visitor (src/meter.rs).

41[[durable_objects.bindings]]
42name = "BUDGET"
43class_name = "Budget"

Every request that was answered, and what people asked (src/archive.rs). It also makes the calls, so the same request is never sent twice.

47[[durable_objects.bindings]]
48name = "ARCHIVE"
49class_name = "Archive"

The key is a secret, not a var. Declaring it makes wrangler dev read it from the process environment (op-env-run puts it there) and makes wrangler deploy refuse if the deployed Worker lacks it.

Cloudflare's own record of what the Worker did (the owner, 2026-10-02): every invocation logged, with what it logged, and every request traced (fetches, Durable Object calls, the handler). Kept in the account's dashboard: logs 3 days (Workers Free: 200,000 events a day), traces 7 days. Traces count towards Cloudflare Observability billing from 2026-12-01; lower head_sampling_rate before then if they would.
