STRATA v1
An atmospheric transformer with 331.7 million parameters for emulating SCREAM at roughly 4.9 km resolution, using tiles and ten-minute steps. The strata_v1 checkpoint and auxiliary files were published on November 2. Its inputs and outputs are geophysical tensors, not text or images.

Atmospheric simulation research and experimental short-range forecasting on the SCREAM grid.
The code README still announces a future release, but the official repository already contains the public checkpoint. The code documents a known issue with ice precipitation. This is not an operational weather service and does not guarantee quality against real observations.

Weights use OpenMDW 1.1 and code uses Apache 2.0. Some auxiliary fields require CC BY 4.0 attribution. No API pricing is verified; costs depend on GPUs, data and infrastructure. We did not download weights or run the model for this profile.
i Prices change and may depend on level, region or context length. Check the source before making a decision.
05 / EVALUATIONS
How to read the results
“
The paper reports 741 simulated days per wall-clock day on 512 H100s and 48 simulated days per MWh. These measure the research system, not guaranteed checkpoint performance on other infrastructure. It describes 24-hour stability and increasing biases; Inferama has not reproduced the tests.
| Benchmark | Result | Metric | Source |
|---|---|---|---|
| STRATA global throughput | 741 | Simulated days per day | View source ↗ |
| STRATA energy efficiency | 48 | Simulated days per MWh | View source ↗ |
Inferama only highlights a “best result” when the metric, test set, configuration, and date allow for an equivalent comparison. The supplier's figures are presented as claims from its own source.
