18cdf567df fix(logging): zero out response_cost for cache hits in _process_hidden_params_and_response_cost 
When a cached response had `response_cost` pre-calculated in its `_hidden_params`
(from the original response), `_process_hidden_params_and_response_cost` was using
it directly without checking `cache_hit`, so cached responses were reported with
non-zero cost instead of 0.

Fixes test_cost_tracking_with_caching.

fix(tests): use monkeypatch.setenv for Redis pool max_connections tests (#21834) 
Replace patch('litellm._redis._get_redis_client_logic') with monkeypatch.setenv
in test_max_connections_url_config and test_max_connections_url_config_string_value.

The mock was unreliable in CI (REDIS_URL is set to the real Redis Cloud server),
causing the pool to silently use the real config instead of the test config.
Using monkeypatch.setenv tests the full env-var→pool chain more robustly and
matches the actual production code path.

fix(tests): isolate auth in vertex passthrough and spend logs date range tests (#21824) 
test_vertex_passthrough_with_default_credentials and
test_view_spend_logs_with_date_range_summarized fail intermittently when a
prior xdist worker sets master_key — auth then rejects the unauthenticated
test requests before the code under test is reached.

- mock user_api_key_auth in test_vertex_passthrough_with_default_credentials
  (same pattern used for test_vertex_passthrough_with_no_default_credentials
  in #21810)
- wrap test_view_spend_logs_with_date_range_summarized in
  app.dependency_overrides[ps.user_api_key_auth] with try/finally cleanup
  (same pattern used for the other spend log tests in #21810)

fix(tests): isolate litellm.cache and CLI env vars in flaky tests (#21821) 
- TestSpendLogsPayload: save/restore litellm.cache in setup_method/teardown_method
  so tests that run after a cache-setting test don't see a non-None cache and get
  a hash instead of "Cache OFF" in the cache_key field
- test_use_prisma_db_push_flag_behavior: apply clean_env pattern (strip DATABASE_URL/DIRECT_URL,
  then set DATABASE_URL to test value) inside the with block instead of using @patch.dict
  decorator, matching the pattern from test_skip_server_startup to avoid Click 8.3.x

causing a mismatch. Clear both env vars via monkeypatch at the start of each test.

fix(test): add timeout to flush() call to prevent 300s hang in CI (#21819) 
GLOBAL_LOGGING_WORKER.flush() calls queue.join() which blocks until all
items are task_done(). In CI with pytest-asyncio, each test gets a fresh
event loop so the worker reinitializes its queue - items from a previous
test never get task_done(), causing an infinite hang.

Fix: wrap flush() with asyncio.wait_for(..., timeout=10.0).

5f0bef3133 fix(ui): preserve logging_settings in key metadata on update 
The logging_settings condition used a bare truthiness check which
failed when the form field was undefined or not properly synced
from the EditLoggingSettings component. Changed to explicit
Array.isArray() check consistent with the tags field pattern.

feat(router): Add complexity-based auto routing strategy (#21789) 
* feat(router): Add complexity-based auto routing strategy

Adds a rule-based routing strategy that classifies requests by complexity
and routes them to appropriate models - with zero API calls and sub-millisecond
latency.

## Features

- **Zero external API calls** - all scoring is local
- **Sub-millisecond latency** - typically <1ms per classification
- **Weighted multi-dimensional scoring** across 7 dimensions:
  - Token count (short=simple, long=complex)
  - Code presence (code keywords → complex)
  - Reasoning markers ("step by step" → reasoning tier)
  - Technical terms (domain complexity)
  - Simple indicators ("what is" → simple, negative weight)
  - Multi-step patterns (numbered steps)
  - Question complexity (multiple questions)
- **Configurable tier boundaries** and model mappings
- **Reasoning override** - 2+ reasoning markers force REASONING tier

## Usage

```yaml
model_list:
  - model_name: smart-router
    litellm_params:
      model: auto_router/complexity_router
      complexity_router_config:
        tiers:
          SIMPLE: gpt-4o-mini
          MEDIUM: gpt-4o
          COMPLEX: claude-sonnet-4
          REASONING: o1-preview
```

Inspired by ClawRouter: https://github.com/BlockRunAI/ClawRouter

- litellm/router_strategy/complexity_router/complexity_router.py - Main router class
- litellm/router_strategy/complexity_router/config.py - Configuration and defaults
- litellm/router_strategy/complexity_router/__init__.py - Package exports
- litellm/router_strategy/complexity_router/README.md - Documentation
- tests/test_litellm/router_strategy/test_complexity_router.py - Test suite (37 tests)

## Files Modified

- litellm/router.py - Integration with pre_routing_hook
- litellm/types/router.py - New config params

* feat(router): Add complexity-based auto routing strategy

Adds a new rule-based routing strategy that classifies requests by complexity
and routes them to appropriate models - without any external API calls.

## Features
- Weighted scoring across 7 dimensions: token count, code presence, reasoning
  markers, technical terms, simple indicators, multi-step patterns, questions
- Maps to 4 tiers: SIMPLE, MEDIUM, COMPLEX, REASONING
- Each tier configurable to a different model
- Zero API calls, <1ms latency
- Inspired by ClawRouter

## Configuration
```yaml
model_list:
  - model_name: smart_router
    litellm_params:
      model: auto_router/complexity_router
      complexity_router_config:
        tiers:
          SIMPLE: gemini-2.0-flash
          MEDIUM: gpt-4o-mini
          COMPLEX: claude-sonnet-4
          REASONING: claude-opus-4
```

## Use Cases
- Cost optimization: route simple queries to cheaper models
- Quality optimization: route complex queries to capable models
- Zero configuration: works out of the box with sensible defaults

```

- Cost optimization: route simple queries to cheaper models
- Quality optimization: route complex queries to capable models
- Zero configuration: works out of the box with sensible defaults

* feat: add enterprise presets for complexity router

Adds preset configurations for different cloud providers:
- bedrock: AWS Bedrock (Claude models)
- vertex: Google Vertex AI (Gemini models)
- azure: Azure OpenAI (GPT + o1)
- standard: Direct API (OpenAI + Anthropic)
- cost_optimized: Maximum savings (Gemini Flash + cheaper models)

Usage:
```yaml
complexity_router_config:
  preset: bedrock  # or vertex, azure, standard, cost_optimized
```

* feat(ui): update auto router submit handler for complexity router

- Handle complexity_router model type in submit handler
- Generate correct litellm_params for complexity router:
  - model: auto_router/complexity_router
  - complexity_router_config: { tiers: { SIMPLE, MEDIUM, COMPLEX, REASONING } }
- Keep existing semantic router handling intact
- Add success notification with router type name

* docs: update PR description with UI changes

* chore: remove preset feature, keep simple tier config

* fix: exclude complexity_router from auto_router check

The _is_auto_router_deployment() was matching all auto_router/* models,
causing complexity_router to fail initialization. Now it explicitly
excludes auto_router/complexity_router which has its own handler.

* fix(complexity_router): Address Greptile review feedback

Fixes 5 issues flagged in code review:

1. **Mutable singleton mutation bug** - Now always creates a new
   ComplexityRouterConfig instance instead of reusing DEFAULT_COMPLEXITY_CONFIG
   singleton, preventing cross-instance config pollution.

2. **Substring matching false positives** - Added word boundaries (spaces)
   to short keywords like 'ok', 'try', 'api', 'git', 'node', 'java', 'vue'
   to prevent matching within longer words (e.g., 'capital' matching 'api').

3. **Redundant message extraction** - Simplified to single reverse loop that
   extracts both last user message and last system prompt efficiently.

4. **Unused imports** - Removed unused DEFAULT_CREATIVE_KEYWORDS and
   DEFAULT_MULTI_STEP_PATTERNS imports.

5. **Missing async_pre_routing_hook tests** - Added comprehensive tests for:
   - Multi-turn conversations
   - List-type content handling
   - No user message case
   - Empty string content
   - Message preservation
   - Singleton mutation prevention

* fix(complexity_router): Address Greptile review feedback

- Use word boundary matching for short keywords (<5 chars) to avoid
  false positives (e.g., 'api' matching 'capital', 'git' matching 'digital')
- Remove 'ok' from simple keywords (too many false positives)
- Add tests for keyword false positive prevention
- Fix test expectations for edge cases (empty string content, list content)

Addresses: 2/5 Greptile score feedback on PR #21789

* docs(auto_routing): Add complexity router documentation

- Add Complexity Router section to auto_routing.md
- Include comparison table with semantic auto router
- Add Python SDK and Proxy Server configuration examples
- Document all configuration options (tier boundaries, token thresholds, dimension weights)
- Explain how complexity scoring works

* feat(complexity_router): Add eval suite + tune scoring parameters

Added comprehensive evaluation suite with 29 test cases covering:
- SIMPLE tier: greetings, definitions, factual questions
- MEDIUM tier: technical explanations, comparisons, debugging
- COMPLEX tier: architecture design, complex coding
- REASONING tier: explicit reasoning requests
- Regression tests: substring false positive prevention

Tuned scoring parameters based on eval results:
- Lowered tier boundaries (0.15/0.35/0.60) for better tier distribution
- Increased code/technical weights (0.30/0.25) for complex prompts
- Reduced simple indicator weight (0.05) to avoid over-penalizing
- Fixed 'hey'/'hi' keywords to require leading space

Eval results: 29/29 passed (100%)

* fix(complexity_router): Address Greptile review round 2

1. **Empty user message handling** - Changed from falsy check to None check
   to properly distinguish 'no user message' from 'empty string message'

2. **ReDoS prevention** - Changed 'first.*then' to 'first.*?then' (non-greedy)
   to prevent regex backtracking on pathological inputs

3. **Documentation sync** - Updated README.md to match actual config values:
   - Tier boundaries: 0.15/0.35/0.60 (not 0.25/0.50/0.75)
   - Dimension weights: tokenCount=0.10, codePresence=0.30, technicalTerms=0.25,
     simpleIndicators=0.05, multiStepPatterns=0.03, questionComplexity=0.02

4. **Missing UI component** - Added ComplexityRouterConfig.tsx with:
   - Tier-to-model dropdown selectors
   - Descriptions and examples for each tier
   - How classification works explanation

5. **Inline import comment** - Added explanation for why ComplexityRouter
   import is inline (matches AutoRouter pattern, avoids circular imports)

* docs(auto_routing): fix dimension weights and tier boundaries to match config.py defaults

* fix(complexity_router): skip empty string content in async_pre_routing_hook

* fix(router): remove or {} masking None complexity_router_config

* fix(config): remove unused DEFAULT_MULTI_STEP_PATTERNS and DEFAULT_CREATIVE_KEYWORDS exports

* fix(complexity_router): use word boundary matching for all single-word keywords, avoid double-scanning reasoning keywords

* fix(router): clarify circular import comment for ComplexityRouter

* docs(README): fix token thresholds to match config.py defaults

* test(complexity_router): add false positive tests for error/class/merge keyword matching

* fix(complexity_router): align .get() fallbacks with config.py defaults, document system prompt scoring

* fix(config): deduplicate keywords across code and technical lists

fix(logging): resolve cache_hit before hidden_params short-circuit in _response_cost_calculator (#21816) 
Cached responses carry response_cost in _hidden_params from the original call.
_response_cost_calculator was returning that pre-computed cost before checking
cache_hit, so cached responses were billed instead of returning 0.0.

Fix: move cache_hit resolution and early-return to top of the function.

Regression introduced in bdf01fa283 (fix mypy error).

fix(tests): isolate auth in spend logs and vertex passthrough tests (#21810) 
* fix(tests): add app.dependency_overrides for auth in spend logs tests

test_ui_view_spend_logs_with_status, test_ui_view_spend_logs_with_model,
test_ui_view_spend_logs_with_model_id, and test_view_spend_logs_summarize_parameter
all send Bearer sk-test without mocking user_api_key_auth. When a prior test
in the same xdist worker sets master_key, the auth check fails for sk-test
and the test fails intermittently.

Fix: use app.dependency_overrides[ps.user_api_key_auth] to bypass auth,
same pattern as other tests in the same file.

* fix(tests): mock user_api_key_auth in test_vertex_passthrough_with_no_default_credentials

vertex_proxy_route calls user_api_key_auth internally. When a prior test in the
same xdist worker sets master_key, the auth check fails for the test request
and create_pass_through_route is never called, causing assert_called_once_with to fail.

Fix: patch user_api_key_auth as an AsyncMock in the with mock.patch() block.

Previously made a real Vertex AI call with a Wikimedia URL that intermittently
failed with URL_REJECTED-REJECTED_FC_TIMEOUT.

Now mocks HTTPHandler.post and VertexBase._ensure_access_token so the test
verifies the translation (OGG -> file_data with audio/ogg mime_type) without
any real network calls. Runs in ~0.36s instead of ~60s.
