OneSoil and Rainbow Weather Partner on AI Rainfall Forecasting for Farmers

Jun 5, 2026
Zurich-based OneSoil has partnered with Polish startup Rainbow Weather to add a hyperlocal precipitation forecast feature to its farming platform, offering rainfall predictions for specific field coordinates within four-hour windows.

OneSoil has partnered with Rainbow Weather to integrate hyperlocal rainfall forecasting into its precision agriculture platform, announced in a press release. The collaboration introduces a new feature called Hyperlocal Precipitation Forecast, which predicts rainfall probability and intensity within a four-hour time frame for specific field coordinates.

The feature extends OneSoil's existing Virtual Weather Station capability, which already tracks wind speed and temperature. Powered by machine learning models, the system analyzes radar, satellite, and atmospheric data to identify precipitation patterns. According to Rainbow Weather co-founder Alexander Matveenko, this method enables high accuracy in detecting and forecasting short-term rainfall events.

OneSoil CEO Stepan Zulynskyi said the update provides crucial information for farmers managing weather-sensitive tasks such as fertilization and spraying. The feature is already used by more than 15,000 farmers each month. Rainbow Weather’s technology is available globally and supports over 120,000 active users through its forecasting API.

Tensordyne Napier: What If One Rack Could Do the Work of Nine?

Tensordyne

This Tensordyne whitepaper presents Napier, an inference-focused AI processor and rack-scale system based on the company’s TDN Math logarithmic number system. It examines infrastructure requirements for large mixture-of-experts and agentic models, compares major inference architecture approaches, and details the TDN AIP processor, TDN72 pod, TDN Link fabric, and Napier Ultra configuration. The paper reports simulation-based performance, cost, and accuracy-validation results, including Tensordyne’s projected comparison of one Napier rack with a nine-rack Nvidia Rubin plus Groq deployment; the chip is reported as taped out and in fabrication.
