PR #22975: fix: add jp. (Japan) region prefix for claude-sonnet-4-6 Bedrock

Description (problem / solution / changelog)

Description

Adds the missing jp.anthropic.claude-sonnet-4-6 entry to model_prices_and_context_window.json.

Problem

The Japan (jp.) Bedrock cross-region inference profile prefix was missing for claude-sonnet-4-6, while all other region prefixes were present:

  • us.anthropic.claude-sonnet-4-6 ✅
  • eu.anthropic.claude-sonnet-4-6 ✅
  • au.anthropic.claude-sonnet-4-6 ✅
  • global.anthropic.claude-sonnet-4-6 ✅
  • jp.anthropic.claude-sonnet-4-6 ❌ ← this PR adds it

Solution

Added jp.anthropic.claude-sonnet-4-6 with the same pricing/capabilities structure as au.anthropic.claude-sonnet-4-6, consistent with how other JP models are defined (e.g., jp.anthropic.claude-haiku-4-5-20251001-v1:0).

Closes #22972

Changed files

  • litellm/model_prices_and_context_window_backup.json (modified, +30/-0)
  • model_prices_and_context_window.json (modified, +30/-0)

Code Example

$ grep "jp.anthropic.claude-sonnet-4-6" model_prices_and_context_window.json

What happened?

model_prices_and_context_window.json is missing the jp. (Japan) Bedrock cross-region inference profile prefix for claude-sonnet-4-6.

Other region prefixes are present:

  • us.anthropic.claude-sonnet-4-6 ✅
  • eu.anthropic.claude-sonnet-4-6 ✅
  • au.anthropic.claude-sonnet-4-6 ✅
  • global.anthropic.claude-sonnet-4-6 ✅
  • jp.anthropic.claude-sonnet-4-6 ❌ missing

The jp. prefix exists for other models (e.g., jp.anthropic.claude-sonnet-4-5-20250929-v1:0, jp.anthropic.claude-haiku-4-5-20251001-v1:0), so it appears this was simply overlooked for claude-sonnet-4-6.

Expected: jp.anthropic.claude-sonnet-4-6 should be added to model_prices_and_context_window.json with the same structure as the other region-prefixed entries.

Steps to Reproduce

  1. Open model_prices_and_context_window.json
  2. Search for jp.anthropic.claude-sonnet-4-6
  3. No entry found

Relevant log output

$ grep "jp.anthropic.claude-sonnet-4-6" model_prices_and_context_window.json
(no results)

Fix Plan

To fix the issue, add the missing jp. prefix entry for claude-sonnet-4-6 to model_prices_and_context_window.json.

Here are the steps:

  • Open model_prices_and_context_window.json in a text editor.
  • Add the following JSON object with the same structure as other region-prefixed entries:
{
  "model": "jp.anthropic.claude-sonnet-4-6",
  "price": <price_value>, // Replace with the actual price value
  "context_window": <context_window_value> // Replace with the actual context window value
}
  • Save the changes to model_prices_and_context_window.json.

Verification

To verify the fix, run the following command:

$ grep "jp.anthropic.claude-sonnet-4-6" model_prices_and_context_window.json

This should now return the newly added entry.

Extra Tips

  • Make sure to replace <price_value> and <context_window_value> with the actual values for the claude-sonnet-4-6 model.
  • If you're using a version control system, commit the changes to model_prices_and_context_window.json with a descriptive commit message.
