Anthropic vs Amazon Bedrock
Bedrock serves Claude at roughly direct-API prices inside the AWS security model. The real question is whether you want Anthropic alone or Claude plus 100+ other models behind IAM.

Anthropic vs Amazon Bedrock: key differences
Claude is the headline model on Amazon Bedrock, and third-party analyses put Claude at price parity with Anthropic's own API, a notable exception to Bedrock's usual 20 to 35% markup on other models. So cost rarely decides this one. What differs is the wrapper. Anthropic's API is a lab selling its own lineup, from Haiku 4.5 to Fable 5.1, with Batch at 50% off and very cheap Fable cache reads. Bedrock routes every call through IAM, PrivateLink, KMS encryption and CloudTrail logging, and provider models never train on customer data. It also puts GPT-6 Astra, Nova, DeepSeek and Mistral one model ID away.
Regulated enterprises already on AWS usually land on Bedrock, since procurement and security review are largely done and AgentCore adds a serverless agent runtime, an MCP gateway and Cedar-based policies outside the model. Provisioned throughput at 20 to 40% off with a commitment helps steady traffic. Anthropic direct suits teams that are not tied to AWS, want one relationship with the model maker, and do not need model availability to vary by region or managed add-ons like Knowledge Bases that can run up idle charges.
What Anthropic and Amazon Bedrock do
Anthropic
Anthropic sells the Claude family of closed models through its own API, Amazon Bedrock, Google Vertex AI and Microsoft Foundry. The public lineup today runs from Claude Fable 5.1 at the top, released September 1, 2026, through the Opus and Sonnet tiers down to Haiku 4.5. List prices span a tenfold range, from $10 in and $50 out on Fable to $1 in and $5 out on Haiku. The top three tiers include a 1M token context window at standard pricing with no surcharge past 200K.
Example models: Claude Fable 5.1, Claude Haiku 4.5
Full Anthropic profileAmazon Bedrock
Amazon Bedrock is AWS's managed model service and has become the default AI control plane for many enterprises. One API reaches 100+ models from 18+ providers, including Anthropic's Claude family, Meta, Mistral, DeepSeek, Amazon's own Nova models, and, since an April 2026 partnership expansion, OpenAI models up to GPT-6 Astra. Switching models is usually just a new model ID. Every call inherits IAM, PrivateLink, KMS encryption and CloudTrail logging, and provider models never train on customer data.
Example models: Claude Opus, GPT-6 Astra
