Fastino launches Training API with day-zero Nemotron 3.5 Super VL support

Fastino launches the Fastino Training API, a low-level post-training API for running SFT and RL loops on hosted GPUs, with day-zero support for NVIDIA's Nemotron 3.5 Super VL model.

Fastino says switching from Tinker can reduce post-training costs by 25% to 85%. The company is also offering a limited-time discount on training Nemotron 3.5 Super VL on the API, and is releasing two open-weight models fine-tuned from that model with the API, one for finance and one for healthcare. NVIDIA AI shared Fastino's announcement on X.
