OpenAI Launches GPT-6.1 Terra With Faster Speed, Lower Cost and Computer-Use Capabilities

OpenAI has begun rolling out GPT-6.1 Terra, the latest addition to its GPT-6 model series, offering significantly faster performance at a fraction of the cost of comparable models. The release marks a notable step in agentic AI, with Terra capable of understanding screens, navigating apps and automating everyday tasks.

The model delivers performance at the Astra level on the Agents' Last Exam benchmark, runs more than three times faster than its predecessor and costs roughly one-tenth as much per token. Its context window reaches 1.05 million tokens, enabling handling of large and complex workloads in a single pass.

OpenAI priced Terra at $1 per million input tokens, $0.05 per million cached input tokens and $5 per million output tokens for standard API access. The model is being deployed to Code Arena and Agent Arena for public benchmarking and is coming to the API and Codex, expanding its availability to developers building automated and coding workflows.
