OpenAI GPT-6.1 Terra becomes generally available on Amazon Bedrock and GitHub Copilot

What happened

On 26 October 2026, AWS announced that OpenAI’s GPT-6.1 Terra is now generally available on Amazon Bedrock [2]. This model is part of the GPT-6 family and is designed to balance capability, speed, and cost efficiency for everyday workloads [2].

According to AWS, GPT-6.1 Terra features the following technical specifications and performance metrics:

• It provides detailed visual reasoning, accurate computer use, improved factuality, and natural writing compared to GPT-5.6 Terra [2].
• In OpenAI’s Agents’ Last Exam evaluation, it scored 15 percentage points higher than GPT-5.6 Terra [2].
• It performed on par with GPT-6 Astra and completed tasks more than three times faster than both GPT-6 Astra and GPT-6.1 Sol [2].
• The model supports a context window of up to 1 million input tokens and accepts text and image inputs [2].
• Input and output token prices are at least 50% lower than GPT-6.1 Sol and GPT-5.6 Terra [2].

Users can access the model through Amazon Bedrock APIs or by configuring ChatGPT Work and Codex to use it on the platform [2].

Simultaneously, GitHub announced that GPT-6.1 Terra is generally available in GitHub Copilot [3]. The model is intended for everyday agentic coding and terminal work at a lower cost than GPT-6.1 Sol [3]. In early testing, it solved more C# coding tasks and terminal tasks than GPT-5.6 Terra [3]. GitHub Copilot users are billed at provider list pricing under usage-based billing [3].

Who is affected

Developers and enterprise users can use GPT-6.1 Terra for tasks such as investigating codebases, interpreting technical drawings, drafting proposals, and building agents for business systems [2].

In GitHub Copilot, the model is available to the following user groups:

• Copilot Pro
• Copilot Pro+
• Copilot Max
• Copilot Business
• Copilot Enterprise

Administrators for Copilot Enterprise and Copilot Business can manage access via the model policy in Copilot settings [3]. The rollout for GitHub Copilot will be gradual [3]. The model can be selected in the model picker across several environments, including:

• Visual Studio Code and Visual Studio
• Copilot CLI and GitHub Copilot cloud agent
• GitHub Copilot app and github.com
• GitHub Mobile on iOS and Android
• JetBrains IDEs, Xcode, and Eclipse [3].
