OpenAI GPT-5.6 Sol, Terra, and Luna Are Now Generally Available on Amazon Bedrock

Amazon Web Services continues to expand its generative AI ecosystem. The new generation of OpenAI GPT-5.6 models is now officially available through Amazon Bedrock, enabling customers to access OpenAI's latest models using AWS's fully managed AI platform.

The new lineup includes three models:

• GPT-5.6 Sol;
• GPT-5.6 Terra;
• GPT-5.6 Luna.

Each model is optimized for different business use cases.

GPT-5.6 Sol

Sol is the flagship model in the new OpenAI family.

It is designed for:

• advanced reasoning;
• multi-step planning;
• autonomous AI agents;
• large-scale information analysis;
• complex business workflows.

This model is ideal for workloads requiring the highest level of reasoning performance and sophisticated decision-making capabilities.

GPT-5.6 Terra

Terra is designed as the general-purpose model for most production environments.

It delivers:

• high-quality responses;
• fast inference;
• approximately half the cost of the flagship model.

For most enterprise AI applications, Terra offers an excellent balance between performance and cost.

GPT-5.6 Luna

Luna is optimized for maximum speed and cost efficiency.

It is well suited for:

• conversational AI;
• high-volume request processing;
• large-scale inference workloads;
• customer-facing AI services.

More Value from Every Token

According to OpenAI, the GPT-5.6 family has been trained to deliver more useful work from every token processed.

For businesses, this translates into:

• higher productivity;
• lower inference costs;
• better overall return on AI investments.

Benefits of Running GPT-5.6 on Amazon Bedrock

Using the models through Amazon Bedrock provides all the advantages of AWS's managed AI platform:

• a unified API across multiple foundation models;
• seamless integration with AWS services;
• enterprise-grade security;
• no infrastructure to deploy or manage;
• access through Amazon Bedrock's next-generation inference engine.

AWS also emphasizes strong data protection. Prompts and model responses remain protected during inference, with zero operator access enforced at the chip level.

Financial Benefits

Pricing for GPT-5.6 models in Amazon Bedrock matches OpenAI's first-party pricing.

In addition, usage through Amazon Bedrock counts toward existing AWS Commitments, providing additional financial flexibility for enterprise customers.

Conclusion

The availability of GPT-5.6 Sol, Terra, and Luna on Amazon Bedrock significantly expands the capabilities available to organizations building generative AI solutions on AWS.

Businesses can now choose the model that best fits their workloads—from advanced reasoning agents to high-throughput, cost-efficient AI services—while benefiting from Amazon Bedrock's secure, scalable, and fully managed infrastructure.
