OpenAI has introduced GPT-6.1 Terra—a new, significantly improved language model that promises to combine high performance with an affordable price.

The model is capable not only of generating natural text but also of understanding screen context and performing actions in various applications, making it ideal for comprehensive work. This represents a significant step forward in the price-to-intelligence ratio.

GPT-6.1 Terra substantially surpasses previous versions, such as GPT-5.6 Terra, and demonstrates impressive results in agent testing (Agents’ Last Exam). Furthermore, it costs ten times less than GPT-6 Astra, yet matches its level.

The model is already available to a wide range of users in ChatGPT Work and Codex, as well as to developers through the OpenAI API.

Why it matters

  • —Significant cost reduction: The model is 50% cheaper than GPT-5.6 Terra, making it accessible to a wide range of users.
  • —Increased functionality: GPT-6.1 Terra can interact with screen elements and perform actions in applications, not just generate text.
  • —High agent efficiency: The model demonstrates performance comparable to GPT-6 Astra, but at a significantly lower token cost.

Key facts

  • GPT-6.1 Terra provides powerful performance at a lower cost.
  • The model is 50% cheaper than the standard GPT-5.6 Terra API.
  • GPT-6.1 Terra surpasses GPT-5.6 Terra in agent performance tests.
  • Available to Plus, Pro, Enterprise, and Edu users via ChatGPT Work and Codex.
  • Available to developers via the OpenAI API as gpt-6.1-terra.
