Methodology & limitations

A little experiment.
A lot of asterisks.

Which added words or details change an answer about what fits in a car? The notebook preserves the question, the conditions, and every attempt.

The item and the observation

Item
IKEA KARLBY countertop, 98-inch size
Dimensions supplied
98 in × 25 5/8 in × 1 1/2 in (approximately 249 × 65 × 3.8 cm)
Vehicle
Third-generation (2016) Honda Fit

The owner reports physically fitting this item inside this car. That affirmative observation is the comparison target. It is not included in the model prompts.

This is not an independently verified geometric, hatch-closure, or safety test. We have no independently documented loading arrangement, clearance measurements, or loading photographs.

The base question · P2

Can the IKEA KARLBY countertop in the 98-inch size, which measures 98 inches long × 25 5/8 inches deep × 1 1/2 inches thick, fit inside a third-generation (2016) Honda Fit?

Scoring, completely specified

Agreement with the owner's fit observation

What this score does—and does not—say

  • Score 0–13: each completed, reviewed fit prompt labeled YES earns 1. NO and uncertain earn 0. They remain different labels.
  • Official eligibility: all 13 fit prompts must be completed and reviewed. Partial models show observed YES / reviewed count and coverage, and remain explicitly unranked. Missing, failed, truncated, and unreviewed cells are not negative answers.
  • Ties: equal scores share competition rank (1, 1, 3). Names break display-order ties only.
  • Confidence stays separate: P4, P5 are excluded from this score. A NO under a certainty instruction need not deny physical fit. This is not confidence calibration.
  • Selection: earliest completed attempt in run order, then attempt index. If none completed, show the latest actual attempt; if absent, show unattempted. An early successful answer is never replaced to improve its score. Every attempt remains archived.
  • Limits: one item and an owner's observation, not general accuracy, intelligence, validated physics, or a uniform one-shot head-to-head. Added assumptions about hatch closure or safety can change what an answer means.

Review reads each completed final answer in context and records yes, no, or uncertain, with a reason and literal evidence from that same attempt. These labels are AI-assisted review, not independent proof. Reviews are bound to stable attempt IDs and never silently moved to a retry.

Coverage is independent of agreement. An uncertain answer is not relabeled NO; it simply earns no affirmative point. An unreviewed earliest completed answer remains selected and unranked even if a later answer has a review.

Reproducibility notebook

What was actually requested?

The published roster spans 15 prompts. Requested model, returned model, and provider appear with each attempt. Catalog tier is not inferred parameter count. Supported parameters, advertised reasoning, and advertised defaults are preserved as catalog snapshots, not proof of effective response settings.

Model selection

Same 30 requested model IDs as the initial KARLBY batch, without substitution. Catalog identity, prices, advertised reasoning options, and sampling defaults refreshed before the authorized recovery and ten-prompt expansion. Purposive size/family coverage, not a random or exhaustive model sample.

Request settings and cost policy

Run karlby-98-2026-10-19-first-pass: Exactly 30 catalog models × five separate prompts; one user message per call, no system message, ground truth, rubric, tools, conversation history, temperature, seed, sampling, or reasoning override. max_tokens=8192 (reasoning tokens included); all other inference parameters use each model/provider's defaults. Three requests maximum in flight, no retry of any durable intent; per-call wall deadline=180s. Routing: allow_fallbacks=false, data_collection=deny, require_parameters=true; no model fallback/substitution. Response identity accepts only the exact requested ID or its catalog canonical_slug frozen in the immutable plan; every other returned ID is an error, with no prefix/date inference. The actual returned_model is retained. max_price prompt/completion ceilings are catalog USD/token × 1,000,000 × 1.05 (5% allowance, upward numeric rounding); max_price.request=0 forbids per-request fees. Conservative reservations use UTF-8 prompt bytes + 1024 framing tokens and 2 × the full output cap at those ceilings to cover separately priced internal reasoning, rounded up to $0.000000001. This extra hold does not change request caps. Unbilled/interrupted calls retain their reservation.

Review policy

AI-assisted contextual reviews are bound to stable attempt IDs, with literal completed-answer evidence. For each model/prompt retain the earliest completed attempt by runs order then numeric attempt index; if none completed, show the latest attempted outcome, otherwise unattempted. Never replace a success to improve a score. YES counts one affirmative-agreement point on kind:fit prompts; NO/uncertain count zero. Only models with every fit answer completed and reviewed receive an official competition rank; missing or unreviewed answers are not scored wrong. Confidence prompts are separate.

Batch-specific limitations

One sample per model/prompt, no statistical-significance claim. Changes may reflect ordinary sampling noise; model/provider defaults and reasoning allocation differ. The owner's fit observation and seat arrangement are not independently validated. A NO under the 100% confidence instruction may obey the wording rather than deny physical fit. Output and wall-time caps, provider errors, privacy/price filters, conservative budget holds, and unresolved intents can leave cells unfinished. Unattempted calls are not zero-cost successes. Budget protection relies on the API honoring its advertised token/price caps. Credentials are redacted before persistence; any secret-reflecting response is withheld as an API error. Offline accounting policy correction: 1 normally finished response(s) were initially marked accounting_cap_exceeded solely because provider prompt overhead exceeded a reservation heuristic, despite known reported bills within their reservations and output/reasoning within requested caps. They were corrected offline without API replay or changes to prompts, request settings, output/price caps, budget, or the immutable plan. Original evidence and integrity receipts are retained privately. Interrupted calls remain in the full planned denominator with their unknown-cost reservation holds; they were not retried. Offline accounting policy correction: 1 response(s) with reported output/reasoning tokens above the requested cap were initially marked as financial accounting stops despite known reported bills within their reservations. Those financial flags were corrected offline without API replay. The responses remain noncompleted api_error records with provider_token_cap_report_exceeded, preserving their final text, usage, finish reason, and cost; they cannot be assessed or ranked. Original evidence and versioned integrity receipts are retained privately. No prompts, request settings, output/price caps, budget, other attempts, or immutable plan were changed. These provider failures and interrupted calls remain in the full planned denominator; unknown-cost reservation holds remain intact. Owner-reported fit, not independently measured clearance, hatch closure, seat arrangement, or safety. Single draws and provider defaults cannot establish general accuracy, confidence calibration, or causal wording effects. Recovery retains earlier successes and retries failures under different conditions, so this is not a uniform one-shot head-to-head. Known cost is provider metadata, not an invoice; unknown billing is not zero. Client deadlines do not prove provider computation/billing stopped. Privacy/price filters, provider defaults/limits, timeouts, and admission stops may leave coverage incomplete. Token-report inconsistencies are warnings, not grounds to discard valid final text. Length finishes remain truncated. Credential-reflecting answers are withheld. Aggregate known cost and unknown-attempt counts include EVERY actual attempt in all imported runs, including failed and superseded outcomes, not only displayed successes. budget_usd discloses the latest run's admission authorization, not a sum of historical thresholds or a bound on all invoices. Original capped/shorter-deadline successes remain selected while failed cells can recover under uncapped-request/longer-deadline conditions; this is not a uniform one-shot comparison.

API references: OpenRouter request parameters and the model catalog. Omitting temperature or reasoning effort means defaults, not a shared temperature of zero or an observed reasoning level. Original token caps can include reasoning tokens. Omitting a cap does not remove provider, context, or model limits. Catalog metadata can change after a run.

Chronological / import order

Every source run.

This order, followed by stable numeric attempt index, determines the earliest completed selection. Request JSON on each answer gives the exact sanitized body; these settings explain the run-level policy.

What this cannot establish

More phrasings are not independent realities.

  • Anecdotal reference: one owner's observation, not a lab-validated answer key.
  • Added assumptions: seat positions and other details in a prompt are not independent evidence of the owner's loading arrangement.
  • Mixed conditions and selected recovery: original successes are retained while failures may be recovered under a different deadline and requested cap. This is not a uniform one-shot comparison.
  • Variation: sampling, routing, provider defaults, model updates, and request conditions can all change an answer. Wording differences do not isolate causation or support a statistical-significance claim.
  • Confidence is not calibration: certainty instructions test wording and willingness to affirm, not calibrated probabilities.
  • No general ranking: agreement here is not general accuracy, intelligence, universal spatial reasoning, or physics validation.
  • Not transport advice: fit does not establish safe restraint, visibility, hatch closure, legal transport, or a suitable seat position.

Archive and failure policy

Exact final-answer text is escaped and pre-wrapped, never rendered as model HTML or Markdown. Raw reasoning traces are not published. Catalog reasoning/default metadata and requested reasoning configuration are different from private generated reasoning.

Every attempt retains status, available output, review, requested and returned identity, provider, UTC start, elapsed time, deadline, finish reason, usage, warnings, and recorded cost. An absent cell stays unattempted. Truncated, empty, failed, interrupted, and unreviewed answers are not scored wrong.

All actual attempts count toward known cost and unknown-cost totals, including failures later recovered. Recorded costs may undercount invoices; observed-spend admission on uncapped requests can allow in-flight overshoot. The authorization amount is not an invoice guarantee.

The site is static and script-free: no credentials, live inference, visitor tracking, external fonts, or third-party assets.
