OpenAI launches GPT-5.6 with three models: Sol, Terra, and Luna
OpenAI has launched the GPT-5.6 family with three models optimized for different use cases. Sol is the flagship with strong capabilities in coding and agents, while Terra and Luna offer more cost-effective alternatives. Pricing starts from $1 per million tokens with new caching features that offer 90% discounts on cache reads.
WHY IT MATTERS
Sol positions itself as a competitor to Claude models on coding tasks at roughly one-third of the cost, and the launch of ChatGPT Work and multi-agent beta features signal OpenAI's focus on agentic AI as the next frontier for AI products.
