Amazon Bedrock has expanded its offerings to include OpenAI's GPT-5.6 models, now available across more than 25 AWS Regions with cross-Region inference (CRIS). This feature allows requests to be routed to the most available capacity, improving throughput and performance under load. Three GPT-5.6 variants—Sol, Terra, and Luna—support CRIS, each with different capabilities and cost structures, and can be accessed via OpenAI and Amazon Bedrock Converse APIs. AI
IMPACT Enhances scalability and performance for AI workloads by distributing inference across multiple AWS regions.
RANK_REASON This is a product/infrastructure update for an existing model on a cloud platform, not a new model release from a frontier lab.
