Summary

  • fast-forward the fork branch to upstream main
  • bring the fork in sync with LiteLLM 1.82.6 and the upstream responses/reasoning fixes landed before and around 2026-03-22

Verification

  • upstream divergence check: git rev-list --left-right --count HEAD...upstream/main -> 0 0

  the same base path but differ in include_subpath
- Clean up _registered_pass_through_routes in the test finally block to
  prevent stale entries from polluting subsequent tests on failure

- Add 'Contributing to Guardrails' category with links to:
  - Generic Guardrail API (integrate without PR)
  - Adding a New Guardrail Integration tutorial
  - Adding Guardrail Support to Endpoints

- Add 'Team Bring-Your-Own Guardrails' link for team BYOG workflow

These docs existed but were only accessible from the 'LiteLLM AI Gateway'
sidebar. Now they're also accessible when browsing the 'Guardrail Providers'
section.

docs: add Contributing to Guardrails section to Guardrail Providers sidebar
Adds `default_api_key_tpm_limit` and `default_api_key_rpm_limit` to
`GenericLiteLLMParams` so operators can set per-deployment rate limit
defaults in config.yaml. When a key has no model-specific tpm/rpm limit
configured, the proxy falls back to these deployment defaults (Case 2 in
spec). Key-level limits always take priority (Case 1).

- Extends `get_key_model_tpm_limit` / `get_key_model_rpm_limit` with a
  `model_name` param and a priority-4 deployment-default fallback
- Passes `model_name=requested_model` in the parallel request limiter so
  the fallback is triggered at enforcement time
- Adds `"limit"` to `SensitiveDataMasker` non-sensitive overrides so
  `*_limit` fields are not masked in `/model/info` responses
- Adds 17 unit tests covering both spec cases and the `/model/info` path

…82.3 changelog

Helicone (PRs BerriAI#19288, BerriAI#22603) and Langfuse (BerriAI#22390) were present in the
v1.82.0-stable...v1.82.3-stable diff but omitted from the AI Integrations
logging section. Also updates the AI Integrations diff summary count from 2 to 4.

- Use min() across all matching deployments instead of first-wins when
  resolving default_api_key_tpm/rpm_limit for a model group, so
  load-balanced setups with different per-deployment limits always apply
  the most conservative value
- Replace the global SensitiveDataMasker non_sensitive_overrides change
  with a targeted excluded_keys set at the remove_sensitive_info_from_deployment
  call site, avoiding unintended suppression of other fields
- Update the v1 parallel request limiter to pass model_name to
  get_key_model_tpm/rpm_limit so deployment defaults apply there too
- Add 4 tests covering multi-deployment min semantics

Compute get_key_model_tpm/rpm_limit once before the guard condition
instead of calling each function twice (once to check non-None, once to
retrieve). Removes 2 extra llm_router.get_model_list() calls per request
when deployment defaults are active.

…ult limits

async_log_success_event only updated the per-model cache counter when
model_rpm_limit / model_tpm_limit were present in key metadata or
model_max_budget was set. For the new deployment-default path
(default_api_key_tpm_limit / default_api_key_rpm_limit), none of those
conditions held, so current_tpm stayed at zero and tpm enforcement was
never applied across multiple requests.

Extend the guard condition to also trigger when the model group has a
deployment-default tpm or rpm limit, and import the two helpers at
module level.

Co-Authored-By: Claude (claude-sonnet-4-6) <noreply@anthropic.com>
Replace bare _get_deployment_default_tpm/rpm_limit calls in the
async_log_success_event condition with get_key_model_tpm/rpm_limit
(model_name=model_group). The higher-level getters short-circuit on
key/team metadata hits before ever reaching the router, so requests
that don't use deployment defaults incur no extra router lookup. Remove
the now-unused bare helper imports.

Also fix invalid `int = None` type hints in test helper signatures
to `Optional[int] = None`.

BerriAI#23931)

- Change chunk["id"] to chunk.get("id") for compatibility with MiniMax
- ModelResponseStream auto-generates id when None is passed
- Add regression test test_chunk_parser_without_id_field
Move pre-call checks (rate limits, guardrails, budget) to run BEFORE
polling ID creation in the background streaming flow. This prevents the
edge case where a rate-limited request receives a polling ID that
immediately fails.

Changes:
- Add skip_pre_call_logic parameter to base_process_llm_request to allow
  skipping pre-call checks (avoiding double-counting of RPM/parallel requests)
- Run common_processing_pre_call_logic before generating polling ID in the
  responses API endpoint. If rate limits/guardrails fail, return error
  immediately without creating a polling ID
- Background streaming task passes skip_pre_call_logic=True to avoid re-running
  pre-call checks that were already done before polling ID creation
- Add tests verifying skip_pre_call_logic parameter works correctly

Fixes the edge case where polling_via_cache would return a polling ID
for a request that immediately fails due to rate limiting.
- Guard logging_obj for None when skip_pre_call_logic=True: raise ValueError
  if litellm_logging_obj not in data, preventing AttributeError downstream
- Add model=None to common_processing_pre_call_logic call in endpoints.py
  to match style of other call sites
- Add test verifying rate-limited request never receives polling ID
…) directly

Previously the test called common_processing_pre_call_logic in isolation,
making generate_polling_id.assert_not_called() vacuously true. Now the test
calls responses_api() end-to-end so it actually verifies that a rate-limited
request never receives a polling ID.

Enable deployment_affinity, responses_api_deployment_check, and session_affinity to be configured per model group via router_settings.model_group_affinity_config, falling back to global settings for unconfigured groups.

- Add model_group_affinity_config parameter to Router and DeploymentAffinityCheck
- Add _get_effective_flags helper to resolve flags per model group
- Update async_filter_deployments and async_pre_call_deployment_hook to use per-group config
- Add 4 comprehensive tests covering per-group config, fallback, and override scenarios

This allows fine-grained control of affinity behavior across model groups, e.g., enabling stickiness only for cross-provider deployments while leaving other groups free to load-balance.

removing summary: "detailed" expectations — now every default-behavior
