Model overview
An open 4B decision model: send a state and typed options, get a calibrated probability for every option. Served through a Jev-compatible `POST /v1/systemone` API on your own GPU. - **Probabilities, not text:** a calibrated probability for every option, nothing to parse. - **Decision Index 0.3: 60.05** on the complete public suite (our run; v2.0: 54.18). - **Thinks only when unsure:** Auto 0.7 thinks natively on about half of the requests. - **Fast:** median **158 ms** (serial, one request in flight, warm, processing time, one RTX PRO 6000, 200 DI 0.3 requests). - **Web actions:** Mind2Web element selection **92.3 %** (test splits, 6 candidates; v2.0: 84.6 %). - **Reads images and video** zero-shot through Qwen3.5-4B's unchanged vision tower. Video (wald-serve 0.2.2): **87.4 %** on VisualDecisionBench video (7,143 questions, our run), 2.5 s for a 15-second clip with 24 questions (serial, one RTX 5090). - **Small and open:** 4B, Apache-2.0. Self-run, not leaderboard results; how each number was produced: evaluation/v2.1/. DI 0.3 run files: org2ai/Wald-Q4B-decision-index-results.

Limitations & considerations
Sources are insufficient to establish specific limitations. Verify task performance, latency, data policies, licensing and version lifecycle.
Source prices & cost analysis
Prices vary by channel, region and configuration. Channel quotes are listed independently and are not treated as a single official provider price.

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
