Only One AWS Region Supports Llama 3.3 70B Fine-Tuning on Bedrock

A developer querying all 33 Amazon Bedrock regions via the AWS SDK found that only us-west-2 supports fine-tuning of Meta's Llama 3.3 70B model, as of September 2026. Two other regions returned valid responses but lacked Llama 3.3 support, 17 regions reported zero tunable models, and 13 opt-in regions were inaccessible on the test account. Amazon Bedrock's public pricing page lists training costs for Llama 2 and several other models but omits any published rate for Llama 3.3 70B, despite the capability existing and generating real AWS charges. Third-party guides have been found incorrectly applying Llama 2 70B pricing to Llama 3.3 70B, which the developer warns could lead to inaccurate budget estimates. The author recommends deriving cost estimates from an actual training job rather than relying on figures inferred from documentation or community sources.
