OpenAI has announced that all three variants of GPT-5.6, named Sol, Luna, and Terra, will be publicly available starting Thursday, July 9. The company received the green light from the Trump administration after additional testing and meetings with the government. Initially, the model was released only to a small group of trusted partners in late June, following a request from the AI cybersecurity executive order signed by President Trump in early June. That order asked companies to voluntarily submit their most powerful models for government review 30 days before public release.
According to Axios, the administration granted permission for a wider release after subjecting the model to further tests and conducting additional meetings with OpenAI. The Department of Commerce's Center for AI Standards and Innovation performed these tests, with company engineers sent to Washington to address potential questions and concerns immediately. OpenAI had stated that it did not believe this government access process should become the long-term default, but cooperated to ensure a swift release.

Three variants of GPT-5.6: differentiated power and pricing
GPT-5.6 consists of three variants with distinct features and prices. Sol is the most powerful model OpenAI has ever created, designed for complex tasks and advanced research. Terra is intended for everyday use and promises performance similar to GPT-5.5 but at half the cost. Luna represents the most economical option, accessible for developers and businesses with limited budgets. Pricing is per token: Sol costs $5 per million input tokens and $30 per million output; Terra costs $2.50 per million input and $15 per million output; Luna costs $1 per million input and $6 per million output. This differentiation allows OpenAI to cover a wide range of needs, from raw power to cost efficiency.

OpenAI's approach with GPT-5.6 mirrors strategies of other industry players. For example, Sam Altman's recent proposal to distribute OpenAI shares to American citizens raised questions about Europe's role in this new ecosystem. Similarly, incidents such as DeepSeek accidentally creating a ransomware technique highlight how delicate AI security is. OpenAI, for its part, followed a certification process involving the US government, a step that may become common practice for frontier models.
Implications for the AI market and regulation
The launch of GPT-5.6 marks a turning point in the relationship between Big Tech and regulation. Trump's executive order has set a precedent: companies must submit their most advanced models to government review before release. OpenAI accepted this condition to gain public access but expressed hope it would not become a permanent process. Meanwhile, Anthropic had to block access to its Mythos and Fable models to comply, later receiving permission to reactivate them. This scenario highlights a tension between innovation and safety that will characterize the sector in the coming years.

OpenAI's decision to release three variants at different price points could influence the generative AI market. With Sol, the company aims to compete with flagship models from Google and Anthropic; with Terra and Luna, it seeks to democratize access by offering low-cost solutions for developers and SMBs. According to experts, this strategy could accelerate AI adoption in sectors like healthcare, finance, and education. However, ethical and safety concerns remain, as demonstrated by the aforementioned DeepSeek incident.
