OpenAI's GPT-6 line now has three models: Astra for flagship work, Sol for coding and analysis at $2/$10, and Luna for high-volume tasks at $0.10/$0.50. We break down what each one is for, the benchmarks OpenAI published, and what the half-price API cut means for everyday users and developers.
GPT-6 Sol costs 20x more per token than Luna, but the benchmark scores land within two points on DeepSWE. We compare the pricing, the AutomationBench and DeepSWE results, and the cost-per-task math to show which workloads need the expensive model and which are wasting money on it.
xAI released Grok 4.7 on September 21 at the same $2/$6 pricing as Grok 4.6, built on a larger base model with longer reinforcement learning for long-horizon tasks. It nearly doubles its Terminal-Bench score but still trails Fable 5.1 on several tests, and it burns far more tokens per task.
Grok 4.7 keeps the same $2/$6 price as Grok 4.6 but rewrites the base model. Terminal-Bench nearly doubles, hallucinations drop from 34% to 29%, and accuracy stays flat. We compare the vendor table against independent testing, including the token usage that can offset the flat price.
