Strengths
- ✓ Listed at $0 in and $0 out per million on the day we read it
- ✓ 262,144-token window; 25B active parameters out of 560B in a hybrid reasoning mixture-of-experts
- ✓ A free text row with a window big enough for real documents rather than a demo
Limitations
- ! Text only — no images, files or audio
- ! Free listings on this catalogue have been withdrawn before, so $0 here is a reading with a date on it, not a promise
- ! 32,768-token output ceiling, the smallest here after Nano Banana
