Key points
- Sol is the flagship, Terra the balanced tier and Luna the cost-efficient tier.
- The preview described stronger cyber safeguards and automated red-teaming.
- Published performance statements are provider-reported and should not be read as independent replication.
Why it matters
Model families increasingly compete on cost, latency and safety controls alongside headline capability.
Possible impact
