Unsustainable Subsidies

不可持续的补贴

Google, OpenAI, and Anthropic diverged on model pricing: Gemini 3.1 Pro is priced at $2 input and $12 output, GPT-5.5 at $5 and $30 after a short subsidy, and Claude Opus 4.7 stayed at $5 and $25.

Why it matters: HKR-H/K/R all pass, but this is Tom Tunguz commentary on pricing rather than a primary model release. The concrete price spread makes it featured, not must-write.
