Crate bedrock_cost 

bedrock-cost

Calculate AWS Bedrock invocation cost across the non-Anthropic vendors that Bedrock hosts: Meta Llama, Mistral, Cohere, Amazon Titan, and AI21 Jurassic. For Anthropic Claude models on Bedrock, use the companion claude-cost crate, which handles the cache_creation / cache_read fields Claude exposes.

Bedrock IDs are normalized so cross-region inference profile prefixes (us., eu., apac.) and ARN paths resolve to the same base model.

Quick example

use bedrock_cost::{Usage, default_pricing};

let pricing = default_pricing("meta.llama3-70b-instruct-v1:0").unwrap();
let usage = Usage { input_tokens: 1_000_000, output_tokens: 500_000 };
let cost = pricing.cost_for(&usage);
assert!(cost > 0.0);

Cross-region inference profile

use bedrock_cost::default_pricing;
assert_eq!(
    default_pricing("us.meta.llama3-70b-instruct-v1:0"),
    default_pricing("meta.llama3-70b-instruct-v1:0")
);

Pricing is best-effort and dated; verify against https://aws.amazon.com/bedrock/pricing/ before using these numbers for billing.

Structs

Pricing

Per-model rates, USD per 1M tokens.

Usage

Token usage as returned by Bedrock Converse (inputTokens / outputTokens).

Constants

DEFAULT_PRICING_TABLE

Built-in pricing table. Source: aws.amazon.com/bedrock/pricing as of 2026-Q2 for the us-east-1 region. VERIFY before billing — Bedrock pricing varies by region.

Functions

default_pricing

Look up the price table entry for a Bedrock model id.

normalize_model_id

Strip ARN, inference-profile, and version suffixes from a Bedrock model id.
