Root Cause

OpenRouter's live API now reports hy3-preview with context_length: 262144 (up from the original 256000 when the model first launched on 2026-04-20).

get_model_context_length("hy3-preview") hits the OpenRouter metadata cache at step 6 in the resolution chain (before reaching the stale static fallback at step 8), so it returns 262144. The test assertion and the DEFAULT_CONTEXT_LENGTHS static table both have the old value.

Fix Action

Fix

Update both:

  • tests/hermes_cli/test_tencent_tokenhub_provider.py: assert ctx == 262144

Code Example
