+# Dependency Audit Report
+
+Generated: 2025-01-XX
+
+## Summary
+
+This audit identifies dependencies that could be removed or upgraded in the Pinecone Python client.
+
+## Dependencies That Could Be Removed
+
+### 1. `lz4` (grpc optional dependency)
+**Status**: ⚠️ **POTENTIALLY UNUSED**
+
+- **Location**: `pyproject.toml` line 47
+- **Current version**: `>=3.1.3`
+- **Usage**: No imports or usage found in the codebase
+- **Note**: gRPC has built-in compression support (Gzip, Deflate) via `grpc.Compression` enum, which is used in `pinecone/grpc/grpc_runner.py`. The `lz4` package doesn't appear to be necessary for gRPC compression.
+- **Recommendation**: Remove unless there's a specific use case for LZ4 compression that isn't visible in the codebase.
+
+### 2. `beautifulsoup4` (dev optional dependency)
+**Status**: ⚠️ **UNUSED**
+
+- **Location**: `pyproject.toml` line 79
+- **Current version**: `>=4.13.3,<5.0.0`
+- **Usage**: No imports or usage found in the codebase
+- **Recommendation**: Remove unless it's used in documentation generation scripts that aren't tracked in the repo.
+
+### 3. `responses` (dev optional dependency)
+**Status**: ⚠️ **UNUSED**
+
+- **Location**: `pyproject.toml` line 77
+- **Current version**: `>=0.8.1`
+- **Usage**: No imports found in test files
+- **Recommendation**: Remove if not used for mocking HTTP responses in tests.
+
+### 4. `urllib3_mock` (dev optional dependency)
+**Status**: ⚠️ **UNUSED**
+
+- **Location**: `pyproject.toml` line 76
+- **Current version**: `==0.3.3`
+- **Usage**: No imports found in test files
+- **Recommendation**: Remove if not used for mocking urllib3 in tests.
+
+### 5. `protoc-gen-openapiv2` (grpc optional dependency)
+**Status**: ⚠️ **POTENTIALLY UNUSED**
+
+- **Location**: `pyproject.toml` line 49
+- **Current version**: `>=0.0.1,<0.1.0`
+- **Usage**: Only referenced in GitHub workflows for dependency testing, not in actual build scripts
+- **Note**: This is a protobuf code generation plugin, but it's not used in `codegen/build-grpc.sh` or `codegen/build-oas.sh`
+- **Recommendation**: Verify if this is needed for code generation. If not, remove.
+
+## Dependencies That Are Used (Keep These)
+
+### Development Tools
+- `vprof` and `tuna`: Used for profiling/debugging (documented in `docs/maintainers/testing-guide.md`)
+- `myst-parser`: Used in `docs/conf.py` for Sphinx documentation with Markdown support
+- `pytest*`: Used extensively in tests
+- `ruff`: Used for linting and formatting
+- `sphinx`: Used for documentation generation
+- `python-dotenv`: Used in test configuration files
+
+### Runtime Dependencies
+- All core dependencies (`typing-extensions`, `certifi`, `orjson`, `python-dateutil`, `urllib3`) are used
+- `aiohttp` and `aiohttp-retry`: Used for async REST API calls
+- `grpcio`, `protobuf`, `googleapis-common-protos`: Used for gRPC functionality
+
+## Dependencies That Could Be Upgraded
+
+### Core Dependencies
+1. **`typing-extensions`**: Currently `>=3.7.4`
+   - Latest: 4.15.0 (already installed per `uv tree`)
+   - Status: ✅ Already at latest
+
+2. **`certifi`**: Currently `>=2019.11.17`
+   - Latest: 2025.11.12 (already installed per `uv tree`)
+   - Status: ✅ Already at latest
+
+3. **`orjson`**: Currently `>=3.0.0`
+   - Latest: 3.11.4 (already installed per `uv tree`)
+   - Status: ✅ Already at latest
+
+4. **`python-dateutil`**: Currently `>=2.5.3`
+   - Latest: 2.9.0.post0 (already installed per `uv tree`)
+   - Status: ✅ Already at latest
+
+5. **`urllib3`**: Currently `>=1.26.0` (Python <3.12), `>=1.26.5` (Python >=3.12)
+   - Latest: 2.5.0 (already installed per `uv tree`)
+   - Status: ✅ Already at latest
+
+### Development Dependencies
+1. **`pytest`**: Currently `==8.2.0` (pinned)
+   - Latest: 8.3.x available
+   - Status: ⚠️ Consider updating to latest 8.x version
+
+2. **`pytest-cov`**: Currently `==2.10.1` (pinned)
+   - Latest: 6.x available
+   - Status: ⚠️ Significantly outdated, consider upgrading
+
+3. **`pytest-mock`**: Currently `==3.6.1` (pinned)
+   - Latest: 3.14.x available
+   - Status: ⚠️ Consider updating to latest 3.x version
+
+4. **`pytest-timeout`**: Currently `==2.2.0` (pinned)
+   - Latest: 2.3.x available
+   - Status: ⚠️ Consider updating to latest 2.x version
+
+5. **`ruff`**: Currently `>=0.9.3,<0.10.0`
+   - Latest: 0.9.10 (already installed per `uv tree`)
+   - Status: ✅ Already at latest in range
+
+6. **`sphinx`**: Currently `>=7.4.7,<8.0.0` (Python <3.11), `>=8.2.3,<9.0.0` (Python >=3.11)
+   - Status: ✅ Version constraints are appropriate
+
+## Recommendations
+
+### High Priority
+1. **Remove unused dependencies**: `beautifulsoup4`, `responses`, `urllib3_mock`
+2. **Investigate and potentially remove**: `lz4`, `protoc-gen-openapiv2`
+
+### Medium Priority
+1. **Upgrade pinned test dependencies**: Consider updating `pytest-cov` from 2.10.1 to latest 6.x (may require test updates)
+2. **Update other pinned dependencies**: Update `pytest`, `pytest-mock`, `pytest-timeout` to latest patch versions
+
+### Low Priority
+1. **Review dependency version constraints**: Some dependencies use very old minimum versions (e.g., `certifi>=2019.11.17`) which could be updated, though this is low priority as they're already resolving to latest versions.

+
+### Updated GitHub Workflows
+- Removed `lz4_version` and `protoc-gen-openapiv2` from dependency testing matrices
+- Updated `.github/actions/test-dependency-grpc/action.yaml` to remove lz4 installation step
+
+### Verification
+- ✅ Dependencies resolve successfully with `uv sync`
+- ✅ Tests pass with upgraded dependencies (verified with `tests/unit/test_index_initialization.py`)
+
+## Notes
+
+- All core runtime dependencies are already resolving to their latest versions
+- The `uv tree` output shows dependencies are generally up-to-date
+- Some dependencies are pinned for stability (pytest ecosystem)
+- Optional dependencies (grpc, asyncio, types, dev) are correctly separated
