OpenAI launches GPT-6 Sol, halving errors and cutting costs by 99%

OpenAI launched its next-generation AI models, GPT-6 Sol and GPT-6 Luna, three months after the release of GPT-5.6.

GPT-6 Sol reduces error rates by approximately 50% compared to its direct predecessor.

GPT-6 Luna matches the performance of the high-tier GPT-5.6 Sol at 1% of the cost.

The dual-release strategy targets high-end performance and cost-sensitive applications to broaden AI adoption and intensify market competition.
