What moved
GPT-6 Astra was the only GPT-6-generation model in the registry → GPT-6 Sol and GPT-6 Luna added to the registry, with a model page for GPT-6 Sol; no tracked OpenAI plan prices either yet
OpenAI released the GPT-6 mid and low tiers on 2026-09-22: GPT-6 Sol (gpt-6-sol) at $2/$10 per 1M tokens with cached input $0.20 and cache writes $2.50, and GPT-6 Luna (gpt-6-luna) at $0.10/$0.50, both with a 1.05M-token context and 128K max output. Astra stays the $10/$50 frontier tier above them. Both identifiers are live on OpenAI’s own model and pricing pages; they enter the registry here, and the plans that serve them are being checked provider by provider, so no plan model list, price or cap changed in this entry.
