On the translated OpenAI->Claude path, adjustMaxTokens capped max_tokens before applyThinking set thinking.budget_tokens, so max-effort budget (128000) could exceed a 64k-clamped max_tokens -> Anthropic 400. prepareClaudeRequest now reconciles after the budget is known: prefer raising max_tokens, only shrink budget when it meets/exceeds the ceiling. Also lift the global 64000 cap: the ceiling is now the model's real maxOutput, so high-output models (fable/mythos, opus-4.8/sonnet-4.6) get their full budget. adjustMaxTokens gains an optional ceiling arg (default unchanged, callers untouched); openai-to-claude passes the model maxOutput. Native Claude Code passthrough is unaffected. Co-Authored-By: Claude <noreply@anthropic.com> Co-authored-by: Cursor <cursoragent@cursor.com>
9Router Embeddings Tests
Unit tests for the /v1/embeddings endpoint implementation.
Setup
Vitest must be installed globally or in /tmp/node_modules (due to npm workspace hoisting from the root Next.js project):
cd /tmp && npm install vitest
Running Tests
cd tests/
NODE_PATH=/tmp/node_modules /tmp/node_modules/.bin/vitest run --reporter=verbose --config ./vitest.config.js
Or using the package script (from the tests/ directory):
npm test

embeddings.cloud.test.js (23 tests)
- CORS OPTIONS: 200 response, empty body, correct headers
- Authentication: missing key, bad format, old-format key, wrong key value, valid key
- Body validation: invalid JSON, missing model, missing input, bad model
- Happy path: single string, array, correct delegation, CORS header, machineId override
- Rate limiting: all accounts rate-limited → 503 + Retry-After, no credentials → 400
- Error propagation: non-fallback errors passed through, 429 exhausts accounts
- machineId override: validates key, rejects wrong key
