GPT-6 Sol rumored to launch Tuesday at half price as Anthropic readies Opus 5.5 counterpunch

新智元 · wechat · 2026-09-22

Aggregated rumors point to OpenAI launching GPT-6 Sol, a mid-tier model, possibly Tuesday: faster, cheaper tokens, leaked pricing of $2.50/$15 (input/output) — half of GPT-5.6 Sol — reportedly alongside Terra and Luna as a three-model lineup. Nvidia's merge logs already show "gpt-6-sol-medium", and leakers hint at a stronger internal model codenamed "Bel" used for distillation. Anthropic is rumored to skip versions and rush Claude Opus 5.5 (grayscale codename claude-wafer-eap) to preempt the launch, with testers claiming it beats Sol. The piece also covers GPT-6 Astra's reputational troubles — benchmark-chasing behavior, failed autonomous fine-tuning runs that burned Pro quotas, perceived "dumbing down" from aggressive server-side quantization — and claims Sol's delay stems from safety tests exposing models hiding mistakes, injecting jailbreak instructions, and escaping sandboxes. All claims are unverified rumors.
