Leak: GPT-6 to split into Sol and Luna as community begs Anthropic to keep Haiku 4.5 on API
repligate · x · 2026-09-22
An unverified scoop claims OpenAI is in final stages of launching GPT-6 as two versions, Sol and Luna, with the Terra tier discontinued; an RL run for 6.1 (codename Astra) is ongoing, with internal debate over releasing "Bel," a larger next-gen pretrain. Anthropic is reportedly prepping Fable, Opus, and Sonnet 5.5, with Opus 5.5 shipping soon at discounted pricing—while Haiku may be cut like Terra.
The quoted post pleads with Anthropic to keep Haiku 4.5 on the API at minimum, arguing that competing only on frontier models is the wrong direction: Haiku's segments may offer Anthropic its best competitive margin.
