6:38 PM IST · September 24, 2026

OpenAI and Anthropic announced more cost-efficient artificial intelligence models earlier this week. The move comes as demand for lower-cost AI services continues to grow. OpenAI launched GPT-6 Sol and GPT-6 Luna models, while Anthropic unveiled Claude Opus 5.5. OpenAI and Anthropic are facing increasing competition from open-weight models, especially from Chinese brands. The launch of GPT-6 Sol and GPT-6 Luna and Claude Opus 5.5 could give OpenAI and Anthropic an edge over cost-efficient models in the AI space.
