OpenAI’s general release of GPT-5.6 is important for reasons that extend well beyond another round of benchmark charts. Frontier AI has been moving toward permissioned access, trusted-user programs, government restrictions, and models whose most powerful capabilities are reserved for a small group of approved institutions. Making GPT-5.6 broadly available is a positive reversal of that trend.
Across our businesses, we have been running GPT-5.6 inside the Hermes agent harness. The improvement over GPT-5.5 is remarkable. It stays on task longer, uses tools more intelligently, follows complex workflows with less supervision, and is materially better at turning an objective into a finished product. In practice, it feels competitive with Anthropic’s Claude Fable 5, particularly when the model is paired with the right harness, tools, memory, and operating procedures.
That last part matters. A frontier model sitting behind a chat box is interesting. The same model inside a well-designed agent system can actually operate a business. Small companies now have access to intelligence and execution capacity that would have required entire teams a few years ago.
The most important feature of GPT-5.6 is that ordinary businesses can actually use it.
