OpenAI announced price cuts for its GPT-5.6 Sol model, lowering input to $4 and output from $30 to $20 per million tokens, representing a reduction of over 20% (33% for output). The company attributes this to improved model efficiency and infrastructure optimization. Analysts view this as a move to pressure Anthropic during its IPO roadshow and counter low-cost Chinese models. Meanwhile, Codex surpassed 20 million weekly active users.
