GPT-6 Sol and GPT-6 Luna land on Arena, API pricing 50% below GPT-5.6 promo rates

GPT-6 Sol 和 GPT-6 Luna 上线 Arena，API 定价比 GPT-5.6 促销价低 50%

OpenAI dropped GPT-6 Sol and GPT-6 Luna on Arena, both built on GPT-6 Astra tech. The pitch is faster, cheaper inference with better caching for high-volume workloads. API pricing is 50% below GPT-5.6's promotional rate. The post doesn't disclose benchmark scores or latency numbers, so I'd wait for third-party benchmarks before getting excited.

Why it matters: OpenAI drops two GPT-6 models on Arena with API pricing 50% below GPT-5.6's promo rate — strong price signal. But no benchmarks or latency data in the post, so can't tell if performance took a hit. Score stays below 85 until third-party tests land.
