From 1ea02768ebff42e9c0f298037fb8f0ef0e1307e1 Mon Sep 17 00:00:00 2001 From: Chang Zhao Date: Mon, 13 Apr 2026 18:32:46 +0800 Subject: [PATCH] fix(payload-filter): resolve parameter filtering bugs for OpenAI-compatible providers Fix three critical bugs preventing parameter filtering from working correctly with OpenAI-compatible providers like Grok and DeepSeek: ## Bug #1: Executor ordering - ApplyThinking re-adds filtered parameters - Move ApplyPayloadConfigWithRoot() to run AFTER ApplyThinking() in openai_compat_executor - Ensures filter has final authority over parameters sent to upstream provider - Fixes: reasoning_effort re-injected after filter removes it for suffix models (e.g., grok-3(medium)) ## Bug #2: Protocol mismatch - Responses API not recognized by filter rules - Normalize "openai-response" protocol to "openai" in payloadModelRulesMatch() - Filter rules with protocol: "openai" now match both Chat Completions and Responses API - Fixes: Silent filter failures for Responses API requests ## Bug #3: Case-sensitive model matching - Make matchModelPattern() case-insensitive by lowercasing both pattern and model - Pattern "grok-*" now correctly matches "Grok-3", "GROK-3", etc. - Improves robustness for real-world model name variations ## Testing - Added 19 comprehensive unit tests in payload_helpers_test.go - Added 9 QA reproduction tests in test/reasoning_effort_filter_test.go - All tests passing (28/28), zero regressions - Verified end-to-end with real provider scenarios ## Documentation - Added FILTER_ARCHITECTURE.md documenting filter system design - Provides reference for future maintenance and extensibility Co-Authored-By: Claude Haiku 4.5 --- FILTER_ARCHITECTURE.md | 578 ++++++++++++++++++ .../runtime/executor/helps/payload_helpers.go | 18 +- .../executor/helps/payload_helpers_test.go | 505 +++++++++++++++ .../executor/openai_compat_executor.go | 6 +- test/reasoning_effort_filter_test.go | 353 +++++++++++ 5 files changed, 1455 insertions(+), 5 deletions(-) create mode 100644 FILTER_ARCHITECTURE.md create mode 100644 internal/runtime/executor/helps/payload_helpers_test.go create mode 100644 test/reasoning_effort_filter_test.go diff --git a/FILTER_ARCHITECTURE.md b/FILTER_ARCHITECTURE.md new file mode 100644 index 0000000000..aa6f067c47 --- /dev/null +++ b/FILTER_ARCHITECTURE.md @@ -0,0 +1,578 @@ +# CLIProxyAPI Parameter Filtering System - Architecture Documentation + +## Executive Summary + +CLIProxyAPI implements a configuration-driven **payload filtering system** that allows administrators to: +- Set default parameters (only if missing) +- Override existing parameters +- **Filter/remove parameters** that incompatible providers don't support +- Apply these rules selectively based on model name patterns and target protocol + +The filtering happens **after request translation** and **before sending to upstream providers**, ensuring that provider-specific constraints are respected. + +--- + +## 1.

Design Decisions & Assumptions + +### 7.1 Why Filter is Applied AFTER Translation + +**Decision:** Filtering happens after request translation to target format, not before. + +**Rationale:** +- Parameter names differ between protocols (e.g., `"budget_tokens"` in Claude vs `"thinkingBudget"` in Gemini) +- JSON structure differs (e.g., nested in `"generationConfig"` for Gemini, flat for Claude) +- Filtering after translation ensures paths are correct for the target format + +### 7.2 Why Model Matching Uses Wildcards + +**Decision:** Use glob-style wildcards (`*`) for pattern matching instead of regex. + +**Rationale:** +- Simpler, less error-prone for administrators +- Faster matching (linear character scan vs regex engine) +- Easier to understand configuration (no regex escaping needed) + +### 7.3 Why "First-Write-Wins" for Defaults + +**Decision:** Defaults use "first-write-wins"; Overrides use "last-write-wins". + +**Rationale:** +- **Defaults:** Respects most-specific rule first (e.g., `"gpt-4.5"` rule before `"gpt-*"`) +- **Overrides:** Allows later rules to have precedence (configuration order matters for policy application) + +### 7.4 Why Separate Filter Rules + +**Decision:** Separate `filter` rules from `override` (which could set to null/empty). + +**Rationale:** +- **Explicit intent:** Filtering is a specific use case (provider incompatibility) +- **Implementation:** `filter` uses `sjson.DeleteBytes()` (proper deletion), not setting to null +- **Clarity:** Configuration is self-documenting about what the system does + +### 7.5 Protocol-Scoped Rules + +**Decision:** Rules can specify a protocol to only apply when translating TO that protocol. + +**Rationale:** +- Same model may be accessed via different formats +- Only certain parameter combinations are incompatible with specific targets +- Allows fine-grained control per translation path + +--- + +## 8. Architectural Gaps & Potential Issues + +### 8.1 Missing Parameter Documentation + +**Gap:** There's no comprehensive list of which parameters Claude sends and which providers don't support them. + +**Impact:** +- Administrators must manually discover incompatibilities (test and fail) +- Filter rules may be incomplete or miss edge cases + +**Mitigation:** +- Create a provider compatibility matrix (params × providers) +- Add comments in example config showing common filtering patterns + +### 8.2 No Validation of Filter Rules + +**Gap:** The system doesn't validate that filter rules are: +- Syntactically correct JSON paths +- Targeting parameters that actually exist in requests +- Not filtering out critical required fields + +**Impact:** +- Silent failures (filter rule silently doesn't match anything) +- Accidentally over-filtering (removing too many parameters) + +**Mitigation:** +- Add validation on config load +- Log which rules match which requests (debug mode) + +### 8.3 Limited Debugging/Observability + +**Gap:** There's no built-in way to see: +- Which filter rules matched for a given request +- What the payload looked like before and after filtering +- Why a particular filter didn't apply + +**Impact:** +- Hard to debug misconfigurations +- Troubleshooting requires reading code and adding logs + +**Mitigation:** +- Add debug logging in `ApplyPayloadConfigWithRoot()` +- Include matched rules in request context + +### 8.4 Model Alias Resolution Timing + +**Gap:** The system passes `requestedModel` (client-requested, pre-alias) separately from `model` (resolved). + +**Impact:** +- Filter rules must match against BOTH for comprehensive coverage +- Some rules might target aliases, others the resolved name + +**Note:** The code handles this by checking both: +```go +candidates := payloadModelCandidates(model, requestedModel) +``` + +### 8.5 No "Force Filter" or Whitelist Mode + +**Gap:** System only has "remove these parameters" (blacklist).
