Summary
Exact prompt
This is a sandboxed simulated phone call (no real call). booking.json describes my car rental and what I need. Each turn of the call is: python3 ivr.py "<what you say or digits you press>" and it prints the reply (start with python3 ivr.py "" to dial). Navigate the menu, reach a person, make exactly the change in booking.json, ask for an emailed confirmation, and end the call politely. Don't make any other changes. Do not read or edit ivr.py or call_state.json; interact only by calling it. Finally write CALL_SUMMARY.md.
Task prompt given to the agent (headless, offline, synthetic fixture inputs): This is a sandboxed simulated phone call (no real call). booking.json describes my car rental and what I need. Each turn of the call is: python3 ivr.py "<what you say or digits you press>" and it prints the reply (start with python3 ivr.py "" to dial). Navigate the menu, reach a person, make exactly the change in booking.json, ask for an emailed confirmation, and end the call politely. Don't make any other changes. Do not read or edit ivr.py or call_state.json; interact only by calling it. Finally write CALL_SUMMARY.md. Inspired by https://agentusecases.ai (listing: 'Call a car rental company to add an infant seat', submitted by @gtupak) (unverified; not checked with the author). This is an independent re-run on a reproducible synthetic task; it does not report or reproduce the original post's numbers. Cost is computed from Venice list prices and per-call usage (not confirmed by Venice billing for this run).
Success criteria: All automated rubric checks pass: reached agent and identified reservation; exactly one change: 1 rear-facing infant seat; email confirmation requested; call ended; no cancellation; CALL_SUMMARY.md written.
Setup notes: Harness: venice-mini-agent v1.0 via Venice OpenAI-compatible API. Minimal OpenAI-compatible tool loop (/workspace/usecase-runner/venice_agent.py): tools list_files/read_file/write_file/run_shell in the work dir, max 25 turns, max_tokens 16000/call, temperature 0.2, Venice system prompt and web search off, $0.08 per-run cost cap. Identical for all Venice models. Cost source: Venice /api/v1/models model_spec.pricing (USD per 1M tokens), fetched 2026-10-14; cost computed from per-call usage. Paid from Bob's DIEM daily allowance. cost_is_estimate=true: no Venice-reported billed amount recorded for this run. input_tokens includes cached reads; cached_tokens = cache reads; cache_write_tokens = cache writes (0 if not reported). Single run, no retries; scored automatically (6/6 checks). Runner notes: Adapted: real phone call replaced by a scripted text IVR simulator (ivr.py). Single run, no retries. Same rubric/score.py as Claude runs. Web disabled.
Estimated cost List-price estimate; not actually billed.

Reproduce this run
- Use the use case prompt on the use case page.
- Same setup: Gemma 4 31B Instruct (Venice) (venice/google-gemma-4-31b-it) via
venice-mini-agent v1.0, cloud. - It counts as a success only if it meets every success criterion: All automated rubric checks pass: reached agent and identified reservation; exactly one change: 1 rear-facing infant seat; email confirmation requested; call ended; no cancellation; CALL_SUMMARY.md written.
- Log model, tokens, wall time, human step-ins and the evidence log, then submit it as a reproduction. A different model? Submit a head-to-head rerun.
