Rate limits and availability. A rate-limit message does not mean your prompt is invalid. Models marked free run on a provider pool shared by every OpenRouter user, so they return HTTP 429 whenever that pool is saturated — which is common and unpredictable. This is not your account's quota, and buying credits does not raise it. For anything you plan to run live in class, select a paid model. The explorer retries retryable failures up to three times; if a paid model still fails, wait briefly and try again, shorten the prompt, or fall back to Cached Examples.

View request. Appears under each generated response. The first block is the JSON this page sent to the Worker; the second is what the Worker forwarded to the model provider, including the response cap and logprob settings the page cannot change. Everything in both blocks left your browser.

Privacy, retention, and training. Do not enter confidential, privileged, personal, or client information. Everything you submit — prompt, system prompt, and the returned response — leaves this browser, passes through this site's Cloudflare Worker and OpenRouter, and reaches a third-party model provider. Assume it is retained and used to train future models. Free models are commonly offered on the condition that prompts may be logged and used for training; paid providers vary, and some contractually do not train on API traffic, but neither this site nor your instructor controls or can audit what a provider retains. Use the View request panel under any response to see exactly what was transmitted.

Results. Generated text and token probabilities come from the selected live model and can vary between requests. Responses are capped at 60 generated tokens and prompts at 8,000 characters. Cached Examples are real captures from the live model — genuine text and genuine probabilities — recorded once and committed to the repository so class time never depends on the network. Regenerate them with scripts/capture-cached-examples.mjs.

Acknowledgment. This exercise was inspired by Rebecca Fordon's TokenExplorer.

Setting the prompt. ⚙ Settings → Exercises → Hallucinated Citations sets the instruction students see — for example, narrowing the round to a family law case. Saving pushes it to phones already sitting on the form and echoes it on this screen under the heading. Blank restores the default. Changing the prompt never clears the board; archive the round first if you want a clean slate.

Clearing and exporting. Clear archives the current class and empties the board — it is not a delete. Export downloads one CSV of every citation ever collected: each archived round plus whatever is on the board now, one row per citation, tagged with its session, the prompt that was in effect, and the student who submitted it. Names are collected on the form but never shown on the board — they only appear in the export. Aggregate across classes in a spreadsheet without keeping anything on screen.

Sample data. The sample toggle shows citations from a past class (names removed) so the exercise can be rehearsed or demonstrated with nobody submitting. Live submissions stay in Firebase while it is on — they are only hidden.

Sub-processes. Some parts of a process are processes of their own. Claims is an input to drafting a complaint, but it is also the output of researching claims, exercising legal judgment, and choosing which to plead. Mark a card as a sub-process with its ⧉ button (hover over the card to see it): it gets a stacked look and a line where you can name the process that produces it. Click the line to edit it. Press ⧉ again to hide the line — the stack and the ⧉ button stay visible, so the card still reads as a process of its own. Remove, at the end of the line, turns it back into a plain card.

Arrows. Hover over a card, click the dot on its right edge, then click another card to draw an arrow (dragging from the dot works too; Esc or a click on empty space cancels) — for example, from Client's story to Organize the facts. Any card can point at any other, as many times as you like, including a function that leads to another function. Select a card to highlight its arrows. Click an arrow to select it, then click its × or press Delete to remove it. Deleting a card removes its arrows.

Saving. The board saves automatically in this browser and is still there after a refresh. Nothing is sent anywhere, so a board built on the classroom computer stays on that computer. Clear empties the board; Example loads a sample complaint-drafting board for rehearsal.
