Amazon has completed its $50 billion investment in OpenAI by deploying the final $35 billion in two tranches over recent months, according to a securities filing released Friday.

OpenAI has cut prices on two models in its GPT-5.6 series: Luna by 80% to $1.40 per million tokens combined, and Terra by 20% to $14 per million tokens combined, while introducing a premium Fast mode for its flagship Sol model at double the standard price. The moves come days after Anthropic released Claude Opus 5 at competitive pricing and Google launched lower-cost Gemini models, signaling a shift in AI competition toward cost and speed rather than capability alone. Luna now competes directly with the market's low-cost inference tier, though it remains more expensive than some alternatives like DeepSeek's flash model.
