Sticker research · Supply Bench

Frontier models on multi-vendor procurement workflows

We evaluate computer-use agents from approved request through supplier ordering, line allocation, exception handling, and reconciliation. Every task is deterministic and scored from final system state against programmatic rubrics.

Procurement judgment

The data behind this pilot

Visible product specifications, pack quantities, inventory, delivery dates, contract pricing, shipping thresholds, and clinic policies drive every accepted outcome. Tasks permit plausible wrong purchases to submit so the verifier captures concrete procurement mistakes.

  • 17% pass@1 across 18 graded attempts.
  • Claude Fable 5 passed 1/9 graded attempts with 65% mean reward.
  • GPT-5.5 passed 2/9 graded attempts with 61% mean reward.
  • 5/18 attempts ended without a terminal disposition; 12 completed purchases across both suppliers, and 4 submitted a reconciled outcome.

Methodology: cohort v3-final-100step; target 3 attempts per task-model. Strict pass = a submitted, fully defensible procurement outcome. Mean reward = the average weighted verifier score from 0 to 1. Near-perfect identifies reward ≥ 0.95 and does not count as a strict pass. V2 and V3 results are never combined.

Observed failure modes

Patterns across the selected v3 cohort.

  • Incomplete execution. 5 attempts stopped before committing a terminal procurement disposition.
  • Cross-system execution. 12 attempts successfully created orders with both supplier portals.
  • Post-order recovery. 4 attempts completed discrepancy resolution and submitted reconciliation.

Environment details

Platform

Sticker coordinates approved requests across HEALTH SUPPLY and BUSINESS SUPPLY, then records supplier orders, allocations, escalations, and reconciliation.

Harness

Stagehand v3 CUA owns the browser loop in local headless Chromium at 1280×800. The exact model ID and every deduplicated frame are retained.

Scoring

Hard gates cover structure, product policy, authorization, deadline, financial objective, escalation quality, reconciliation, and terminal integrity.

Run selection

The fixed cohort includes every selected OpenAI and Anthropic attempt. Provider or authentication errors are excluded from the graded denominator.
