OpenAI has released GPT-6 Sol and Luna, mid-tier and budget variants of its flagship Astra model. Sol delivers Astra-level performance on complex tasks at 9% of competitor costs, while Luna achieves comparable reasoning at 1/100th of Astra's price. Both use the same training approach as Astra, excelling in code generation, factual accuracy, and computer control. These cost reductions directly benefit SMEs and developers: Sol at $2/M input tokens ($10/M output) and Luna at $0.10/$0.50 represent permanent pricing that makes enterprise AI automation significantly more accessible and cost-effective for scaling workloads.
