Hosting Large Language Models on Amazon Bedrock

Published On: 29 May 2025

The rise of Large Language Models (LLMs) like Claude, GPT, and Jurassic-2 has revolutionized how businesses automate, create, and serve customers. These models can write content, summarize data, generate code, and even hold contextual conversations. Their growing use across industries—healthcare, legal, education, finance—signals a shift in how organizations operate. From startups to Fortune 500 companies, the adoption of LLMs is rapidly accelerating, becoming a key driver of innovation and productivity in AI-powered workflows. like Claude, GPT, and Jurassic-2 has revolutionized how businesses automate, create, and serve customers. These models can write content, summarize data, generate code, and even hold contextual conversations. Their growing use across industries—healthcare, legal, education, finance—signals a shift in how organizations operate.

However, one of the biggest challenges remains: how do you host these powerful models efficiently, securely, and at scale?

Enter Amazon Bedrock—a serverless, fully managed service by AWS that allows you to build and scale generative AI applications using a selection of top-tier foundation models. This blog dives into everything you need to know to get started.

The Problem with Manual Social Selling

Understanding On-Demand, Batch, and Latency-Optimized Modes

Below is a comparison of the three primary inference modes in Amazon Bedrock:

ModeUse CaseBilling BasisAdvantages
On-DemandReal-time apps with dynamic loadPer 1,000 tokens or imageFlexible, scalable; no setup or commitment required
BatchLarge-scale predictions processed togetherPer 1,000 tokens50% cheaper than on-demand; input/output handled via S3
Latency-OptimizedInteractive apps needing instant responsesPer 1,000 tokensUltra-fast response; optimized for specific models (e.g., Claude 3.5 Haiku, Llama 3.1 405B/70B)

These modes allow teams to select the right trade-off between responsiveness, scale, and cost depending on their application’s requirements.

  1. On-Demand Mode: You pay only for what you use, with no time-based commitments. Charges are based on:
  1. A token is a basic unit of text (typically a few characters) used by models to understand and respond to prompts.

  2. Cross-Region Inference: Supported in On-Demand mode. Lets you manage traffic bursts using compute from multiple AWS Regions. No extra cost—pricing is based on your source region.

  3. Batch Mode: Ideal for bulk predictions. Submit multiple prompts via a file and receive batched responses in an S3 bucket. Batch inference is offered at ~50% lower cost than On-Demand mode for select models.

  4. Latency-Optimized Mode: Offers faster response times for interactive applications. Available for:

  1. Verified by model providers to deliver industry-leading speeds on AWS infrastructure.

VM Requirements and Cost for Model Hosting

When hosting custom models or using provisioned throughput on Amazon Bedrock, each model requires one or more Model Units, which determine the VM capacity needed to serve inferences reliably. A Model Unit is a compute bundle optimized for different model architectures and sizes. Here’s how VM sizing translates to model usage and estimated monthly costs:

Model NameEstimated Model UnitsHourly Rate (No Commitment)Monthly Cost (720 hrs)Use Case
Claude 3.5 Haiku1$0.001~$0.72Fast Q&A, basic chatbots

Limitations of Amazon Bedrock


Final Thoughts

If you’re looking to quickly build, test, and scale Large Language Model-powered apps without managing compute infrastructure, Amazon Bedrock is one of the fastest and safest ways to go live.

Its flexibility, model diversity, and serverless setup make it ideal for startups, enterprises, and developers who want to focus on innovation—not infrastructure.

By giving you access to the world’s leading Large Language Models, Bedrock removes the roadblocks that usually slow down AI development. You don’t need to manage GPUs, handle scaling logic, or patch together separate APIs. Instead, you can bring your generative AI use case to life in days—not months.
