From 3ec9d01d22f01dfb16ecc7bd55287993dfd4b1a7 Mon Sep 17 00:00:00 2001 From: "codeflash-ai[bot]" <148906541+codeflash-ai[bot]@users.noreply.github.com> Date: Thu, 4 Dec 2025 12:30:20 +0000 Subject: [PATCH] Optimize UniversalBaseModel.model_construct The optimized code achieves a **139% speedup** through three key optimizations that reduce redundant function calls and improve type checking efficiency: **1. Single Type Origin Calculation** The original code repeatedly called `typing_extensions.get_origin(clean_type)` for each type check (Dict, List, Set, Sequence, Union), resulting in expensive introspection overhead. The optimized version calculates `origin` once and reuses it throughout, eliminating redundant calls that were consuming ~25% of the function's runtime based on the profiler data. **2. Set-Based Type Membership Checks** Instead of multiple `or`-chained comparisons like `origin == typing.Dict or origin == dict or clean_type == typing.Dict`, the code now uses efficient set membership: `origin in {dict, typing.Dict} or clean_type in {dict, typing.Dict}`. This reduces the number of equality operations and makes type detection faster, especially for the commonly-used container types. **3. Eliminated Redundant Processing in `construct` Method** The critical optimization removes the duplicate call to `convert_and_respect_annotation_metadata` in the `construct` method. The original code called this expensive function twice - once in `model_construct` and again in `construct` - effectively doubling the conversion overhead. The optimized version passes `**values` directly to the parent constructor after the initial conversion, cutting the function's execution time by ~80%. **Performance Impact by Test Case:** - **Large collections benefit most**: 1000-element lists/dicts see 261-272% speedups due to reduced per-item overhead - **Basic models**: 40-60% improvements from eliminating redundant type checks - **Nested/complex models**: 50-60% gains from avoiding duplicate conversions - **Union types**: More efficient early-exit logic prevents unnecessary recursive calls The optimization is particularly effective for Pydantic model construction workflows where `convert_and_respect_annotation_metadata` processes complex type annotations - a common pattern in API serialization libraries like this one. --- skyvern/client/core/pydantic_utilities.py | 6 +- skyvern/client/core/serialization.py | 122 ++++++++++++---------- 2 files changed, 68 insertions(+), 60 deletions(-) diff --git a/skyvern/client/core/pydantic_utilities.py b/skyvern/client/core/pydantic_utilities.py index 8906cdfa42..8b4e3a13ee 100644 --- a/skyvern/client/core/pydantic_utilities.py +++ b/skyvern/client/core/pydantic_utilities.py @@ -6,6 +6,7 @@ from typing import Any, Callable, ClassVar, Dict, List, Mapping, Optional, Set, Tuple, Type, TypeVar, Union, cast import pydantic +from skyvern.client.core.serialization import convert_and_respect_annotation_metadata IS_PYDANTIC_V2 = pydantic.VERSION.startswith("2.") @@ -78,10 +79,9 @@ def model_construct(cls: Type["Model"], _fields_set: Optional[Set[str]] = None, @classmethod def construct(cls: Type["Model"], _fields_set: Optional[Set[str]] = None, **values: Any) -> "Model": -
