OpenAI has significantly reduced the prices for its GPT-5.6 model family, with the Luna tier now 80% cheaper and the Terra tier 20% less expensive. This cost reduction was largely driven by engineering optimizations, including the GPT-5.6 Sol model autonomously rewriting its own inference kernels to improve efficiency. These gains in serving costs are expected to make more AI applications, such as high-volume classification and agentic tasks, economically viable at scale. AI
IMPACT Accelerates adoption of AI agents and complex workflows by drastically reducing the cost of inference.
