This Thursday, OpenAI finally launched its Sol and Sol Ultra models (the GPT-5.6 family). The release arrived not because of, but in spite of the authorities: the technology was essentially wrestled from the grip of the US Department of Commerce and the AI Innovation Center. Since late June, the models have been languishing in "closed testing" while officials struggled to assess the risks of such progress. OpenAI has already offered a biting critique of the delay, arguing that administrative barriers simply deprived businesses of the market's most powerful tools while regulators performed a charade of diligence.
The Numbers That Matter
Technological dominance is proven by data, not press releases. According to the TerminalBench 2.1 benchmark, Sol Ultra scores 91.9%, decisively outperforming Anthropic’s Claude Mythos 5, which sits at 88%. The base Sol model follows closely at 88.8%. However, real-world efficiency is the more compelling story:
In cybersecurity tasks, Sol matches Mythos 5’s performance while utilizing three times fewer tokens. For the corporate sector, this translates beyond "smart chat" to a radical reduction in computational overhead for complex audits.
The Price War
The project’s economics look like a formal declaration of war against competitors. Priced at $5 per million input tokens and $30 per output, Sol is exactly half the price of Anthropic’s Fable 5 ($10/$50). When you factor in architectural efficiency—the model consumes fewer resources for the same task—the gap in the final bill for enterprise clients becomes even more dramatic.
However, it is too early to celebrate: the industry is suspended in a legal vacuum. OpenAI rightly points to the lack of clear safety standards under the latest Trump executive order.
Officials currently hold the power to block releases without providing transparent testing criteria. While the State Department and the Department of Commerce play a game of safety without rules, businesses are left to wonder if every future AI iteration will become a hostage to administrative whim, or if the market will finally break through the bureaucratic machine.
