# Atlas with Amazon Nova Pro in 2026 > Amazon Nova Pro offers a 300K token context window at $0.80 / $3.20 per Mtok, making it a cost-effective choice for Atlas. Amazon Nova Pro is an excellent choice for Atlas developers in 2026 seeking a cost-effective model with deep AWS integration. It provides a substantial 300K token context window at $0.80 per Mtok for input and $3.20 per Mtok for output, making it ideal for tasks where price and existing AWS infrastructure are key considerations within Atlas's terminal-native AI coding agent. ## Key takeaways - Amazon Nova Pro offers a 300K token context window for Atlas. - Pricing is $0.80 / $3.20 per Mtok (input / output), roughly a sixth of Claude Opus 4.8's rate. - Billed through existing AWS accounts, simplifying procurement and IAM. - Trails Claude and GPT-5 in raw agentic coding capability. - Atlas authenticates Bedrock via standard AWS credential chains. - Region-prefixed model IDs (us., eu.) can be a misconfiguration point. ## What is Amazon Nova Pro best at with Atlas? Amazon Nova Pro excels within Atlas for developers prioritizing cost efficiency and direct AWS integration in 2026. With its 300K token context window and pricing at $0.80 / $3.20 per Mtok, it offers a significant financial advantage, roughly a sixth of Claude Opus 4.8's rate. Amazon Nova Pro's primary strength for Atlas users is its highly competitive pricing and deep integration with the AWS ecosystem. At $0.80 per Mtok for input and $3.20 per Mtok for output, it presents a compelling cost-benefit, especially when compared to other frontier models. This model bills directly through your existing AWS account, eliminating the need for new vendor contracts and simplifying procurement, IAM, and data residency management. Atlas authenticates Bedrock through standard AWS chains, including AWS_ACCESS_KEY_ID, AWS_PROFILE, AWS_BEARER_TOKEN_BEDROCK, or web identity token files, ensuring a smooth setup for developers already operating within AWS. Atlas's ability to switch the active model and provider on the fly means developers can leverage Nova Pro for cost-sensitive tasks and easily transition to other models as needed. ## What are the cost and context tradeoffs of Amazon Nova Pro with Atlas? Amazon Nova Pro offers a substantial 300K token context window and highly competitive pricing at $0.80 / $3.20 per Mtok for Atlas users in 2026. However, its main tradeoff is that its raw agentic coding capability trails other leading frontier models. While Amazon Nova Pro provides a generous 300K token context window, allowing Atlas to process large codebases and extensive documentation, and boasts an attractive price point of $0.80 per Mtok for input and $3.20 per Mtok for output, developers should be aware of its performance tradeoffs. The model's strength lies in its cost-effectiveness and procurement simplicity through AWS, not in its current agentic coding capabilities. For complex, highly nuanced agentic coding tasks, Amazon Nova Pro clearly trails models like Claude and GPT-5. This means that while it is excellent for many routine or cost-optimized operations within Atlas, it may not be the top choice for scenarios demanding the absolute highest level of autonomous problem-solving or intricate code generation. ## When should I choose a different model over Amazon Nova Pro for Atlas? Developers should consider alternative models for Atlas when the highest tier of agentic coding capability is paramount, even if it means a higher cost than Amazon Nova Pro's $0.80 / $3.20 per Mtok rate. Nova Pro's capability trails leading models like Claude and GPT-5 in 2026. If your Atlas workflow demands the absolute best in agentic coding performance, particularly for highly complex or novel programming challenges, you should consider models that surpass Amazon Nova Pro's current capabilities. While Nova Pro offers a 300K token context window and excellent pricing, its performance in agentic coding clearly trails models such as Claude and GPT-5. For tasks requiring advanced reasoning, intricate multi-step problem-solving, or highly creative code generation, the superior capability of these alternative models might justify their higher cost. Additionally, developers switching regions should be mindful that Bedrock model IDs are region-prefixed (e.g., us., eu.), which can lead to misconfiguration if not handled carefully, potentially prompting a switch to a model with a simpler ID structure. ## How does Atlas leverage Amazon Nova Pro's capabilities? Atlas effectively utilizes Amazon Nova Pro's 300K token context window and cost-efficient pricing to enhance various coding workflows in 2026. Features like Axis, Atlas's hybrid semantic and keyword code search, benefit from the model's ability to process large code indexes without incurring prohibitive costs. Atlas is designed to maximize the utility of models like Amazon Nova Pro. With its 300K token context window, Nova Pro allows Atlas to maintain a comprehensive understanding of large codebases, supporting features such as Axis, the hybrid semantic and keyword retrieval fused by reciprocal rank fusion. Atlas indexes code by AST declarations using tree-sitter, not blind line windows, which, combined with Nova Pro's large context, enables more precise and relevant code interactions. The model's cost-effectiveness makes it practical for Atlas to perform extensive operations like drafting plans in a read-only plan agent, computing unified diffs for every file edit, and fanning out work to subagents, all while keeping costs manageable. Atlas's ability to switch models on the fly means developers can use Nova Pro as a default for many tasks, only switching to more expensive, higher-capability models when specific, demanding agentic coding tasks require it. ## Setup 1. Configure AWS credentials as usual: export AWS_PROFILE=my-profile and export AWS_REGION=us-east-1 2. Enable the Nova Pro model in the Bedrock console for that region (models are opt-in per account) 3. Run atlas models amazon-bedrock to confirm Atlas resolved it 4. Select amazon.nova-pro-v1:0 from the /models dialog ## FAQ ### What is the context window size for Amazon Nova Pro with Atlas? Amazon Nova Pro provides a substantial 300K token context window when used with Atlas, enabling the processing of large codebases and extensive documentation. ### How much does Amazon Nova Pro cost per token for Atlas users? For Atlas users, Amazon Nova Pro is priced at $0.80 per Mtok for input and $3.20 per Mtok for output, offering a cost-effective solution compared to many other frontier models. ### Does Amazon Nova Pro integrate with existing AWS accounts for Atlas?
