From 0126c8db73d3993b0564965a79dce35442e10ba1 Mon Sep 17 00:00:00 2001 From: "devin-ai-integration[bot]" <158243242+devin-ai-integration[bot]@users.noreply.github.com> Date: Sat, 10 Oct 2026 15:30:54 -0700 Subject: [PATCH 01/12] fix(sagemaker): keep AWS credentials out of the sagemaker_chat request body (#45724) * fix(sagemaker): keep AWS credentials out of the sagemaker_chat request body sagemaker_chat and sagemaker_nova built the container body from every optional param, so aws_access_key_id, aws_secret_access_key, aws_session_token and the other aws_* auth params, plus model_id and sagemaker_base_url, were sent in the JSON body to the endpoint container. The request is still SigV4-signed with the same credentials, which stay in optional_params for signing * fix(sagemaker): limit the sagemaker_chat body filter to aws_ params model_id and sagemaker_base_url are not credentials, so they stay in the body as before and the change sticks to what the fix is about * test(sagemaker): assert the whole sagemaker_chat request body * fix(sagemaker): filter the sagemaker_chat body with the shared AWS auth param list * test(sagemaker): cover the sagemaker_chat body on every endpoint, credential source, and outage ---------

Oct 2026 16:00:27 -0700 Subject: [PATCH 03/12] feat(guardrails): add decision model guardrail with Admin UI flow (#45663) * feat(guardrails): add decision_model guardrail for decisions-API models Adds a new guardrail provider that scores request and response text with a decisions-API model (e.g. Jev) against named predicate checks. Each check carries its own threshold and action (block or log); a flagged block check rejects the request with a 400 naming the flagged checks, and call failures honor unreachable_fallback (fail_open or fail_closed). Ships four preset checks for the Admin UI (prompt injection, jailbreak, system prompt extraction, data exfiltration) served from /guardrails/ui/add_guardrail_settings, plus a Decision Model step in the add-guardrail form filtered to evaluation-mode models. Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(guardrails): fail closed on verdict errors and drop comments in decision_model * feat(guardrails): cap decision_model input with head and tail elision * fix(guardrails): list only block checks in decision_model 400s and tighten inputs * feat(guardrails): honor timeout, cap checks at MAX_DECISION_QUESTIONS, and reject duplicate check names * fix(guardrails): decorate decision_model apply_guardrail with log_guardrail_information * fix(guardrails): suppress untyped-decorator pyright error on log_guardrail_information import * feat(guardrails): screen each text in overlapping chunks with a shared decisions-call semaphore Replace head/tail elision with per-text screening: each non-empty text is sent to the decision model on its own, split into overlapping chunks when it exceeds max_input_chars, and all calls run under a per-event-loop semaphore shared across requests (max_concurrent_decision_calls, default 8). Check verdicts aggregate the max probability across calls; a missing predicate answer on a Block check blocks under fail_closed and only warns under fail_open, while log-only checks are never flagged for it. The 400 detail now lists flagged check names only. The provider combobox also matches Decision Model on jev, typesafe, prompt injection, jailbreak, and decision * fix(ui): align decision model custom check rows with preset rows * fix(ui): move decision model custom check remove button to the row end * style(ui): run prettier on decision model check files * fix(ui): inline decision model evaluation-mode filter after lens module removal * fix(guardrails): keep decision model detections when a chunk call fails * fix(ui): require an enabled decision model check before create * fix(guardrails): screen decision model texts sequentially like presidio * feat(guardrails): replace decision model presets with provider picker and per-question test * fix(ui): render decision model question test as a full-width row * feat(ui): add run-history test section to decision model form * fix(ui): prevent threshold overlap and show test shortcut * feat(guardrails): default decision model threshold to 0.7 * test(ui): expect decision model default threshold 0.7 in characterization payload * feat(guardrails): screen tool call arguments with the decision model * refactor(guardrails): freeze the decision model config model * feat(guardrails): list only evaluation-mode deployments in the decision model picker * feat(guardrails): hide the decision model questions table until a question exists * style(ui): format DecisionModelFields * style(ui): format decisionModelQuestion tests * refactor(guardrails): type the tool call function extraction * refactor(guardrails): build tool call texts without a mutable accumulator * refactor(ui): share isDecisionMode for the decision model picker * fix(guardrails): screen prior Responses function call arguments in the decision model guardrail The Responses input handler leaves function_call arguments out of texts and tool_calls, so a prompt injection in a prior call's arguments passed unscreened. Assistant tool calls from structured messages are now screened too, deduplicated against the request's tool calls * test(integration): send instructions with the decision model guardrail check Checks require instructions, so creating the guardrail returned 422 and the test never sent a chat request * fix(ui): score the decision model test preview the way the guardrail does An unanswered block question now shows Block, disabled questions no longer count, and a run is hidden once the model or a question's text changes since it was scored * fix(ui): clear the decision model error on pick and list questions under Add a question Picking a model after a failed Create left "Select a decision model" on screen, because the form only validates on submit. The field now revalidates when it already shows an error. The Questions table and its heading appear only once a question exists, below the Add a question box * test(ui): move the decision model form tests into an integration test file They render the whole AddGuardrailForm, so they belong in a .integration.test.tsx file. Plain fields are now filled with fireEvent.change, and the two existing form test files go back to main apart from the modelHubCall mock the form now needs * test(guardrails): build the decision model test params without mutating a local * fix(guardrails): reject list checks outside decision_model and honor streaming scan settings - LitellmParams now rejects a list `checks` for any guardrail other than decision_model, so a Bedrock guardrail with list checks gets 422 again instead of being stored and failing every request - The decision model guardrail reads streaming_end_of_stream_only and streaming_sampling_rate, so a streamed post_call response can be scored once at end of stream instead of every 5 chunks - max_concurrent_decision_calls is described as a per-worker limit * fix(ui): match guardrail providers like the default picker filter - The provider search uses the Base UI collator filter on the label and the aliases, so searches such as presidio_pii or llm_as_a_judge match again, as they did before the alias filter - Model groups from /model_group/info are parsed defensively and after the providers are populated, so a malformed response cannot empty the provider list * fix(ui): edit decision model questions in place and show passing test chips in green Questions start as an Add question button. Each click adds a blank question card with its name, text, action and threshold, editable until the guardrail is created, mirroring the per-model budget editor. Create and Next reject a blank or duplicate enabled question. Test run verdicts and chips use the success tone for Pass, the error tone for Block and the warning tone for a flagged Log only question * fix(ui): drop the per-question enable checkbox from the decision model form A question is either in the list or removed with its X, so every listed question is sent and scored. The card now labels Name and Question the way it labels Action and Threshold * fix(ui): give the question name field the full card width * fix(ui): show the provider logo on the selected decision provider * fix(ui): show the full threshold slider track on decision model questions * feat(ui): add decision model cards to the guardrail garden Adds a Decision Model section to the guardrail garden with TypeSafe Jev, Perplexity, Microsoft, OpenAI and Databricks cards. Each card opens the create form scoped to that provider's decision models. The create form drops the Decision Provider picker and lists every decision model on the proxy with its provider logo, prompts to add a model when none is available, and says that test runs are billed and logged. * fix(ui): shorten the decision model test hint to one line * fix(ui): prefill the decision model from the garden card's provider * chore(ui): regenerate the dashboard API types after merging main --------- Co-authored-by: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> Co-authored-by: yucheng-berri <293926326+yucheng-berri@users.noreply.github.com> --- litellm/decisions/call.py | 4 +- litellm/proxy/_lazy_openapi_snapshot.json | 119 ++- .../proxy/guardrails/guardrail_endpoints.py | 2 + .../decision_model/__init__.py | 109 ++ .../decision_model/decision_model.py | 331 ++++++ .../guardrails/guardrail_initializers.py | 2 +- litellm/types/guardrails.py | 39 +- .../guardrail_hooks/decision_model.py | 65 ++ .../test_decision_model_guardrail.py | 128 +++ .../guardrail_hooks/test_decision_model.py | 974 ++++++++++++++++++ .../_components/GuardrailReadOnlyDetails.tsx | 44 + ...d_guardrail_form.characterization.test.tsx | 2 + ...l_form.decision_model.integration.test.tsx | 540 ++++++++++ .../_components/add_guardrail_form.tsx | 111 +- .../decision_model/DecisionModelFields.tsx | 253 +++++ .../decision_model/DecisionTestSection.tsx | 165 +++ .../buildDecisionModelParams.test.ts | 102 ++ .../buildDecisionModelParams.ts | 55 + .../decisionModelQuestion.test.ts | 302 ++++++ .../decision_model/decisionModelQuestion.ts | 175 ++++ .../_components/guardrail_garden.test.tsx | 41 +- .../_components/guardrail_garden.tsx | 32 +- .../_components/guardrail_garden_configs.ts | 38 + .../_components/guardrail_garden_data.test.ts | 44 +- .../_components/guardrail_garden_data.ts | 57 +- .../guardrail_garden_detail.test.tsx | 20 + .../_components/guardrail_garden_detail.tsx | 15 +- .../_components/guardrail_info_helpers.tsx | 12 + .../src/components/networking.tsx | 4 + .../src/components/ui/combobox.tsx | 3 + ui/litellm-dashboard/src/lib/http/schema.d.ts | 57 +- 31 files changed, 3815 insertions(+), 30 deletions(-) create mode 100644 litellm/proxy/guardrails/guardrail_hooks/decision_model/__init__.py create mode 100644 litellm/proxy/guardrails/guardrail_hooks/decision_model/decision_model.py create mode 100644 litellm/types/proxy/guardrails/guardrail_hooks/decision_model.py create mode 100644 tests/integration/providers/test_decision_model_guardrail.py create mode 100644 tests/unit/proxy/guardrails/guardrail_hooks/test_decision_model.py create mode 100644 ui/litellm-dashboard/src/app/(dashboard)/guardrails/_components/add_guardrail_form.decision_model.integration.test.tsx create mode 100644 ui/litellm-dashboard/src/app/(dashboard)/guardrails/_components/decision_model/DecisionModelFields.tsx create mode 100644 ui/litellm-dashboard/src/app/(dashboard)/guardrails/_components/decision_model/DecisionTestSection.tsx create mode 100644 ui/litellm-dashboard/src/app/(dashboard)/guardrails/_components/decision_model/buildDecisionModelParams.test.ts create mode 100644 ui/litellm-dashboard/src/app/(dashboard)/guardrails/_components/decision_model/buildDecisionModelParams.ts create mode 100644 ui/litellm-dashboard/src/app/(dashboard)/guardrails/_components/decision_model/decisionModelQuestion.test.ts create mode 100644 ui/litellm-dashboard/src/app/(dashboard)/guardrails/_components/decision_model/decisionModelQuestion.ts diff --git a/litellm/decisions/call.py b/litellm/decisions/call.py index 757bc5a9b0a..1ad2f006736 100644 --- a/litellm/decisions/call.py +++ b/litellm/decisions/call.py @@ -85,7 +85,7 @@ class DecisionsCall: litellm_params: Mapping[str, object] = field(repr=False) -def _supported_providers() -> tuple[str, ...]: +def supported_decisions_providers() -> tuple[str, ...]: return tuple( provider.value for provider in LlmProviders @@ -99,7 +99,7 @@ def _provider_config(model: str, custom_llm_provider: str) -> BaseDecisionsConfi None if provider is None else ProviderConfigManager.get_provider_decisions_config(model, provider) ) if provider_config is None: - supported: Final = ", ".join(_supported_providers()) + supported: Final = ", ".join(supported_decisions_providers()) raise litellm.BadRequestError( message=f"Unknown Decisions provider '{custom_llm_provider}'.
