## Caveats

- Public training gyms for agent RL; sandbox environment sale is plausible, but price and self-serve admission not published in captured pages. Quote-led, no CPU/RAM tariff.
- Null values mean unknown, not free/unlimited. No model-token cost, tax or unverified ancillary charge included.
- Native browser/device/task/credit prices with unknown CPU/RAM are deliberately non-priceable. Check regime before interpreting any partial resource estimate.
- Also offers Trajectories: a model-agnostic computer-use harness inside Harbor with uploaded-job inspection and shareable URLs; no price published.

## Verified billing facts and gotchas

1. Public training gyms for agent RL; sandbox environment sale is plausible, but price and self-serve admission not published in captured pages. Quote-led, no CPU/RAM tariff.

## Worked example

Requested: 4 vCPU/8 GiB, 50 simultaneous × 8 h/day × 22 days = **8,800 instance-hours**, 30% CPU; 50 GiB snapshots and 100 GiB egress. A month is 730 hours only when explicitly used in rate conversion.

**Total: unknown.** This product does not publish a verified complete 4-vCPU/8-GiB tariff and/or the service bills a different unit. Fifty concurrent instances and eight-hour sessions are not automatically supported. Neither 30% utilization nor retained snapshots can be converted into free resources. Use the native plan terms above and request the missing CPU/RAM, retention, egress and concurrency quote.

Page captures and documentation indexes/bundles are in `raw/`; provider JSON lists the evidence paths. HN query results were captured separately as `<id>--hn.txt`; they are discovery leads, not current tariff authority. Downloaded docs do not imply every feature was verified; unsupported assertions remain null.
