OpenAI's Sol price cut isn't about Anthropic — it's about the model stack
GPT-56 Sol drops to $4 per million input tokens and $20 per million output, from $5 and $30, following cuts to Luna and Terra last month. Many read it as pressure on Anthropic ahead of its IPO, but the more likely driver: business customers won't just use the most expensive state-of-the-art model for everything anymore, and to the extent OpenAI has the compute to deliver frontier models cheaper, it makes sense to do so.
