test_rerank.py sets litellm.api_base = "http://localhost:4000" which leaked
to all subsequent tests on the same xdist worker, causing connection failures
across every provider (Cohere, Azure, OpenAI, etc.).

The revert of 9711e3adfe left xdist tests without proper state isolation.
Module-level assignments like `litellm.num_retries = 3` in 12+ test files
pollute shared globals, and the fixture was saving/restoring contaminated
values instead of resetting to true defaults.
- Capture true litellm defaults at conftest import time and reset before
each test (local_testing + llm_translation)
- Make llm_translation/conftest.py xdist-safe (skip reload under xdist,
add state isolation)
- Replace asyncio.sleep(2) with polling in cooldown handler tests

The conftest fixtures were saving/restoring the current (potentially
contaminated) values of litellm globals like num_retries instead of
resetting to true defaults. Under xdist, module-level assignments
(e.g. `litellm.num_retries = 3` in 12+ test files) pollute the
shared module state and leak across tests in the same worker.

before each test (local_testing + llm_translation)
- Make llm_translation/conftest.py xdist-safe (skip reload, add
state isolation)
- Replace asyncio.sleep(2) with polling in cooldown handler tests
- Add @pytest.mark.flaky to tests making real API calls under xdist

Router tests: expand conftest save/restore to cover all globals mutated
by router tests (default_fallbacks, tag_budget_config, request_timeout,
enable_azure_ad_token_refresh, num_retries_per_request, model_cost,
token_counter). These were leaking across xdist workers.
Proxy tests: move test_proxy_utils.py (169 parametrized) and
test_proxy_server.py (72 parametrized) from part2 to part1, balancing
~370 vs ~360 tests (was ~129 vs ~600).

The test intermittently fails in CI due to Redis cache write propagation
delays, causing the second call to miss the cache and hit OpenAI directly.

test_parallel_function_call_anthropic_error_msg was flaky because other
tests set litellm.modify_params=True without resetting it. When True,
the validation adds a dummy tool instead of raising UnsupportedParamsError.
Fix: save/restore modify_params around the test.
test_vertex_ai_llama_tool_calling failed on intermittent 404 from the
Llama model endpoint in us-east5. Fix: skip on NotFoundError like
the existing RateLimitError handling.

The test asserts that a ttl=0 cached entry expires immediately, so the
second call should not return cached content. Both calls used the same
mock_response text, making the content != assertion always fail. Use
different mock_response values so a cache hit is distinguishable.

- Replace real OpenAI/Anthropic/Bedrock API calls with mock_response in
~20 cache tests to eliminate network-dependent flakiness
- Remove -x (fail-fast) from caching_unit_tests so all failures are reported
- Add parallelism: 2 with circleci tests run --split-by=timings
- Improve pip dependency cache key (v2-caching-deps) with fallback key

Llama-3.2-3B-Instruct-Turbo is no longer available as a serverless model
on Together AI. Switch to Llama-3.3-70B-Instruct-Turbo which is still
available and has cost data in the model prices map.

Add num_retries=0 to the async acompletion call to prevent retries

request payload format, not retry behavior.

- test_router_context_window_check_pre_call_check_out_group: replace deprecated
gpt-3.5-turbo-1106 (removed from model_cost, returns max_input_tokens=0) with
gpt-4.1-mini + mock_response
- test_async_fallbacks: filter "Task was destroyed but it is pending" messages
that leak from parallel test execution in CI

test_post_call_rule_streaming in test_rules.py sets
litellm.post_call_rules but never cleans up. Since
pytest_collection_modifyitems sorts tests by name across modules,
the leaked rule causes failures in test_streaming.py,
test_register_model.py, and test_sagemaker.py.
Add pre_call_rules and post_call_rules to the isolate_litellm_state
fixture's save/restore and clear lists.

The test relied on a global side effect (customLogger initialization in
litellm_logging.py) from prior tests' success callbacks to dispatch
failure callbacks. When tests run in parallel by file, no prior test
initializes customLogger, so the Router's deployment_callback_on_failure
was never invoked and cooldowns were never set.
Rewrite to directly call deployment_callback_on_failure with a proper
RateLimitError containing retry-after headers, testing the cooldown
logic without depending on the logging callback chain.

- test_hanging_request_azure: mock httpx.AsyncClient.send to simulate slow
response instead of racing real network latency against a 10ms timeout.
The old non-existent deployment (gpt-4o-new-test) returned 404 faster
than the timeout, causing NotFoundError instead of APITimeoutError.
- test_completion_together_ai_llama: update model from deprecated
Meta-Llama-3.1-8B-Instruct-Turbo to Llama-3.2-3B-Instruct-Turbo
(Together AI removed the old model from serverless).
- conftest.py: clear litellm.callbacks list before each test to prevent
proxy hooks (SkillsInjectionHook, VirtualKeyModelMaxBudgetLimiter)
from leaking across tests via Router initialization.

The test was failing because it depended on real API calls to deprecated
models. Now uses mock_response to validate streaming through the router
without external dependencies.

- test_async_fallbacks_streaming: replace deprecated gpt-3.5-turbo fallback
with gpt-4o-mini, fix use of module-level kwargs variable
- test_ausage_based_routing_fallbacks: remove Redis dependency to prevent
shared state across parallel CI containers (test already uses mock_response)

* feat: add sagemaker_nova provider for Nova models on SageMaker
Add support for custom/fine-tuned Amazon Nova models (Nova Micro, Nova Lite,
Nova 2 Lite) deployed on SageMaker Inference real-time endpoints.
Nova uses OpenAI-compatible request/response format with additional
Nova-specific parameters (top_k, reasoning_effort, allowed_token_ids,
truncate_prompt_tokens) and requires stream:true in the request body.
Nova endpoints also reject 'model' in the request body.
Changes:
- New provider: sagemaker_nova/<endpoint-name>
- SagemakerNovaConfig inherits from SagemakerChatConfig
- Override transform_request to strip 'model' from request body
- Override supports_stream_param_in_request_body (True for Nova)
- Extend get_supported_openai_params with Nova-specific params
- Refactored SagemakerChatConfig to use custom_llm_provider param
instead of hardcoded strings (backwards-compatible)
- Consolidated main.py routing for sagemaker_chat and sagemaker_nova
- 22 unit tests + 9 integration tests (skip-gated)
- Documentation with SDK, streaming, multimodal, and proxy examples
- All tests verified against live SageMaker Nova endpoint
* fix: move integration tests to tests/local_testing/ per test directory policy
* fix: remove unused module-level SagemakerNovaConfig instance
The sagemaker_nova_config singleton was never imported or used — the
ProviderConfigManager creates its own instance via the lambda registered
in utils.py. Removing this leftover boilerplate.

Fix genuine regression in responses_api_bridge_check where the second
call assigned to `model_info` instead of `responses_api_model_info`,
preventing gpt-5.4 + tools + reasoning_effort from routing to the
Responses API bridge.
Also update outdated tests:
- Vantage tests: match "csv" file key and use supported column names
- Anthropic caching test: add "type": "custom" to expected tool payload
- Claude Agent SDK test: remove non-deterministic LLM content assertion

The test used fallbacks=[{"gpt-3.5-turbo": ["123"]}] where "123" is a
model_id, but the fallback mechanism treats values as model group names.
This caused a ValueError since no model group "123" exists. Additionally,
mock_response propagates to fallback calls, making mock-based fallback
tests unreliable.
Simplified the test to verify that a RateLimitError doesn't permanently
cool down a deployment for subsequent requests.

The test_chat_completion_low_budget test was flaky because async spend
tracking couldn't reliably catch up within 50 calls with 0.5s sleeps.
Increased to 200 calls with 0.1s sleeps (same total time budget) to
give more opportunities for budget enforcement to trigger.

The recent commit 2a997993d4 replaced httpx.AsyncClient() with
get_async_httpx_client() in ui_sso.py, but the PKCE tests still
patched the old httpx.AsyncClient path. Updated all 10 affected
tests to mock get_async_httpx_client and removed unnecessary
context manager setup since AsyncHTTPHandler is returned directly.

Audio streaming responses may not always report token counts, leading to

gemini-1.5-pro and gemini-1.5-pro-001 were removed from the model
pricing JSON. Tests referencing these models fail because capability
lookups (supports_response_schema, supports_system_messages) return
False when the model isn't in the map. Updated to gemini-2.0-flash.

Keep both sets of tests: upstream's OAuth2 token injection test and
our case-insensitive tool matching tests. Use upstream's version of
the bedrock output_config test (more comprehensive).
gemini/gemini-2.5-flash lacks cache_creation_input_token_cost in the
model cost map, causing a TypeError when the test multiplies
cache_creation_input_tokens by None. Use claude-haiku-4-5 instead,
which has the required prompt caching cost fields.

The test calls OpenAI's gpt-4o-audio-preview model which sometimes
doesn't return usage data in the streaming response. Fixed by:
- Adding @pytest.mark.flaky(retries=5, delay=2) for retry handling
- Fixing usage_obj loop to check chunk.usage is not None
- Skipping gracefully when OpenAI doesn't return usage data

- Replace ModelResponse(stream=True) with ModelResponseStream in
test_unit_test_custom_stream_wrapper_repeating_chunk — stream=True
stores delta as a plain dict causing AttributeError in CustomStreamWrapper
- Accept MidStreamFallbackError alongside InternalServerError in the
repeating-chunk safety check assertion
- Add @pytest.mark.flaky(retries=3) to the live OpenAI audio output
usage test
test_standard_logging_payload_audio: the response field in standard_logging_object
is now a ModelResponse choices dict (since d84e5e381a), not {text: redacted-by-litellm}.
Update both audio and non-audio variants to check choices[0].message.content instead.
Audio is still correctly redacted - the new code creates a fresh ModelResponse with no
audio field, so audio bytes never appear in the payload.
test_partner_models_httpx_streaming: remove qwen3-coder-480b (us-south1) from the
parametrize list - same treatment as llama-4-scout which was removed earlier.
The endpoint is unavailable in CI and the test has been consistently failing.
