fix(bedrock): align Bedrock prices with AWS Price List (Titan, Claude Instant, Nova regional, Nova Premier/Sonic)

[myrison]

TLDR

Problem this solves:

• Eight Bedrock entries in model_prices_and_context_window.json do not match the AWS Price List
• eu. / apac. Nova 2 Lite carry US prices (AWS charges 30% / 20% more there)
• Titan Text Express/Lite and regional Claude Instant are 2x to 6.5x too high
• amazon.nova-premier-v1:0 and amazon.nova-sonic-v1:0 have no Bedrock key at all

How it solves it:

• Sets each price to the AWS Price List on-demand value, citing the SKU
• Adds the two missing models with the same field shape as their siblings
• Keeps litellm/model_prices_and_context_window_backup.json identical to the root file

User Flow

Before: a proxy admin routing Nova 2 Lite through the EU profile sees spend that is 30% below the AWS bill

1. They route bedrock/eu.amazon.nova-2-lite-v1:0 and send POST https://litellm-domain/v1/chat/completions
2. The response header x-litellm-response-cost prices 1M input tokens at $0.33 and 1M output at $2.75
3. https://litellm-domain/ui/?page=logs shows that spend, and the month-end AWS invoice is 30% higher

After: the same request is priced at the AWS EU rate, so the logs page matches the invoice

1. They route bedrock/eu.amazon.nova-2-lite-v1:0 and send POST https://litellm-domain/v1/chat/completions
2. x-litellm-response-cost now prices 1M input tokens at $0.429 and 1M output at $3.597
3. https://litellm-domain/ui/?page=logs shows spend that matches the AWS invoice

Changed values

Prices are USD per 1M tokens, old → new (input / output, cache read where noted). Source: AWS Price List on-demand terms, AmazonBedrock offer version 20261006144726 and AmazonBedrockFoundationModels offer version 20261008235637.

Notes for reviewers:

• eu. and apac. keys are cross-region inference profiles whose member regions have different prices. The EU value follows the convention already used by the eu.amazon.nova-{lite,micro,pro}-v1:0 rows (eu-central-1). For Nova 2 Lite, ap-northeast-1 is the only APAC region with an on-demand SKU in the offer files.
• apac.amazon.nova-{lite,micro,pro}-v1:0 were checked and left unchanged; they equal ap-southeast-2 on-demand exactly.
• Kimi K2 Thinking was checked and left unchanged; the regional values already match AWS on-demand terms.
• Bare Claude keys (for example anthropic.claude-sonnet-4-5-…) and batch, priority and flex tiers are deliberately untouched. Those are modelling decisions outside this PR.
• Nova Premier cache pricing is not added, to keep the new row to sourced fields.

Pre-Submission checklist

• I have added meaningful tests — data-only change to the price JSON; no code path changes. The existing schema check and root-equals-backup check cover it.
• The handful of test files covering my change pass locally: python -c "import json; json.load(open('model_prices_and_context_window.json'))", root file byte-equal to the backup, jsonschema validation against model_prices_and_context_window.schema.json reports 0 errors, git diff --check clean
• My PR passes all required CI/CD checks
• My PR's scope is as isolated as possible; it only solves 1 specific problem
• I have received a Greptile Confidence Score of at least 4/5 before requesting a maintainer review

Screenshots / Proof of Fix

Each new value was read directly from the AWS Price List offer file for the region named above, terms.OnDemand → priceDimensions.pricePerUnit.USD, and multiplied by 1,000 (AWS lists per 1K tokens) to compare with the per-1M figures shown. Example for eu.amazon.nova-2-lite-v1:0 input:

$ curl -sO https://pricing.us-east-1.amazonaws.com/offers/v1.0/aws/AmazonBedrock/current/index.json
$ python3 - <<'EOF'
import json
offer = json.load(open("index.json"))
print("offer version", offer["version"], "published", offer["publicationDate"])
for sku, p in offer["products"].items():
    if p["attributes"].get("usagetype") == "EUC1-Nova2.0Lite-input-tokens":
        for term in offer["terms"]["OnDemand"][sku].values():
            for dim in term["priceDimensions"].values():
                print(dim["unit"], dim["pricePerUnit"]["USD"], term["effectiveDate"])
EOF
offer version 20261006144726 published 2026-10-06T14:47:26Z
1K tokens 0.0004290000 2026-10-01T00:00:00Z

0.000429 per 1K tokens = 4.29e-07 per token, which is the new input_cost_per_token in the diff.
