They talked AI slowdown — then OpenAI and Anthropic dropped cheaper models the same day
On 22 September 2026, about 90 minutes apart per TechCrunch, Anthropic released Claude Opus 5.5 with lower prices and Fable-level performance claims, and OpenAI expanded the GPT-6 generation with Sol and Luna at roughly half the API cost of the 5.6 Sol/Luna series, stressing efficiency and fewer mistakes on internal evals. Fortune framed the dual drop as a price war against recent “AI slowdown” talk. Reporting only from TechCrunch and Fortune — not independent third-party benchmarks, not Astra as the lead, and not a funding round. This is the same-day Opus 5.5 and GPT-6 Sol/Luna story, not Plugin4Shell and not CLOSEDQUORUM.
