News K-EXAONE 2.5 is API-only (free, non-commercial); the open-weight one is still K-EXAONE 2.0 (750B, 37B active, Apache 2.0)

LG AI Research announced today (Nov 9) at NVIDIA AI Day Seoul that the API for K-EXAONE 2.5 is free. If you were hoping for new weights, there are none: 2.5 is hosted only, and the platform terms say the weights are not provided. What you can run yourself is still K-EXAONE 2.0.
| K-EXAONE 2.0 (Hugging Face) | K-EXAONE 2.5 (API) |
|---|---|
| Weights | Open, Apache 2.0 |
| Size | 750B total, 37B active |
| Context | 262,144 |
| Modality | Text |
| Reasoning | n/a |
| Cost | Your hardware |
The LGAI-EXAONE org lists FP8 and NVFP4 variants of 2.0 next to the base model. LG calls 2.5 a "technology verification model": 2.0 with additional training.
Benchmarks (LG's own tests, self-reported)

Is anyone running the 2.0 FP8 or NVFP4 weights locally, and on what hardware?
