【#Tech24H】OpenAI has officially announced the full global rollout of its GPT-5.6 series models. As the most powerful model family from OpenAI to date, this release not only includes multiple versions, but also further integrates advanced coding capabilities directly into the GPT app. With upgrades spanning coding agents to working agents, this round of product design improvements is widely regarded as a direct challenge to Anthropic. The GPT-5.6 series adopt a new celestial naming framework, with three distinct models differentiated across performance, cost-effectiveness and other dimensions. The flagship GPT-5.6 Sol (Sun) is designed for complex reasoning, code development, scientific research and cybersecurity high-end scenarios. The balanced GPT-5.6 Terra (Earth) fits daily general workloads, achieving performance comparable to GPT-5.5 at half the cost. The lightweight GPT-5.6 Luna (Moon) features superior speed and cost advantages, suited for high-frequency invocation scenarios.
