OpenAI Releases GPT-6.1 Series Including Terra, Sol, and Astra Models
Something you can actually use or run today.
On October 26, 2026, OpenAI released the GPT-6.1 series, which includes the mid-range model 'Terra' for agentic workflows, alongside 'Sol' and 'Astra' for enterprise and technical tasks.
The release signals OpenAI's move toward models that can navigate standard user interfaces rather than just processing text or API calls.
Terra fills a critical gap in the mid-range model market, offering enough reasoning for agents to handle UI tasks without the latency of a flagship model. It confirms that the next battleground for LLMs is 'computer use' reliability.
