Compare Source

Announcements

• No large announcements of note this release! We've made a lot of small refinements to streamline your ONNX Runtime experience.

GenAI & Advanced Model Features

Enhanced Decoding & Pipeline Support

• Added "chat mode" support for CPU, GPU, and WebGPU.
• Provided support for decoder model pipelines.
• Added support for Java API for MultiLoRA.

API & Compatibility Updates

• Chat mode introduced breaking changes in the API (see migration guide).

Bug Fixes for Model Output

• Fixed Phi series garbage output issues with long prompts.
• Resolved gibberish issues with top_k on CPU.

Execution & Core Optimizations

Core Refinements

• Reduced default logger usage for improved efficiency(#​23030).
• Fixed a visibility issue in theadpool (#​23098).

Execution Provider (EP) Updates

General

• Removed TVM EP from the source tree(#​22827).
• Marked NNAPI EP for deprecation (following Google's deprecation of NNAPI).
• Fixed a DLL delay loading issue that impacts WebGPU EP and DirectML EP's usability on Windows (#​23111, #​23227)

TensorRT EP Improvements

• Added support for TensorRT 10.8.
• Assigned DDS ops (NMS, RoiAlign, NonZero) to TensorRT by default.
• Introduced option trt_op_types_to_exclude to exclude specific ops from TensorRT assignment.

QNN EP Improvements

• Introduced QNN shared memory support.
• Improved performance for AI Hub models.
• Added support for QAIRT/QNN SDK 2.31.
• Added Python 3.13 package.
• Miscellaneous bug fixes and enhancements.
• QNN EP is now built as a shared library/DLL by default. To retain previous build behavior, use build option --use_qnn static_lib.

DirectML EP Support & Upgrades

• Updated DirectML version from 1.15.2 to 1.15.4(#​22635).

OpenVINO EP Improvements

• Introduced OpenVINO EP Weights Sharing feature.
• Added support for various contrib Ops in OVEP:
  • SkipLayerNormalization, MatMulNBits, FusedGemm, FusedConv, EmbedLayerNormalization, BiasGelu, Attention, DynamicQuantizeMatMul, FusedMatMul, QuickGelu, SkipSimplifiedLayerNormalization
• Miscellaneous bug fixes and improvements.

VitisAI EP Improvements

• Miscellaneous bug fixes and improvements.

Mobile Platform Enhancements

WebGPU Enhancements for Mobile

• Ported the MatMul operator implementation from jsep.
• Measured MatMul performance across various data sizes.
• Expanded GenAI + WebGPU testing on additional physical devices (using BrowserStack).
• Updated mobile packaging CIs to support WebGPU.

CoreML Updates

• Added support for caching generated CoreML models.
• Introduced auto-conversion to FP16 to boost performance with ML Program models.

Additional Mobile Improvements

• Completed AppCenter migration (migrated the C# test app to BrowserStack).
• Continued analysis of Executorch.
• Conducted ARM Kleidi AI mobile performance testing.

Extensions & Tokenizer Improvements

Expanded Tokenizer Support

• Now supports more tokenizer models, including ChatGLM, Baichuan2, Phi-4, etc.
• Added full Phi-4 pre/post-processing support for text, vision, and audio.
• Introduced RegEx pattern loading from tokenizer.json.

Image Codec Enhancements

• ImageCodec now links to native APIs if available; otherwise, falls back to built-in libraries.

Unified Tokenizer API

• Introduced a new tokenizer op schema to unify the tokenizer codebase.
• Added support for loading tokenizer data from a memory blob in the C API.

Infrastructure & Build Improvements

Runtime Requirements

All the prebuilt Windows packages now require VC++ Runtime version >= 14.40(instead of 14.38). If your VC++ runtime version is lower than that, you may see a crash when ONNX Runtime was initializing. See https://github.com/microsoft/STL/wiki/Changelog#vs-2022-1710 for more details.

Updated minimum iOS and Android SDK requirements to align with React Native 0.76:

• iOS >= 15.1
• Android API >= 24 (Android 7)

All macOS packages now require macOS version >= 13.3.

CMake File Changes

CMake Version: Increased the minimum required CMake version from 3.26 to 3.28.
Python Version: Increased the minimum required Python version from 3.8 to 3.10 for building ONNX Runtime from source.
Improved VCPKG support

Added the following cmake options for WebGPU EP

• onnxruntime_USE_EXTERNAL_DAWN
• onnxruntime_CUSTOM_DAWN_SRC_PATH
• onnxruntime_BUILD_DAWN_MONOLITHIC_LIBRARY
• onnxruntime_ENABLE_PIX_FOR_WEBGPU_EP
• onnxruntime_ENABLE_DAWN_BACKEND_VULKAN
• onnxruntime_ENABLE_DAWN_BACKEND_D3D12

Added cmake option onnxruntime_BUILD_QNN_EP_STATIC_LIB for building with QNN EP as a static library.
Removed cmake option onnxruntime_USE_PREINSTALLED_EIGEN.

Fixed a build issue with Visual Studio 2022 17.3 (#​23911)

Modernized Build Tools

• Now using VCPKG for most package builds.
• Upgraded Gradle from 7.x to 8.x.
• Updated JDK from 11 to 17.
• Enabled onnxruntime_USE_CUDA_NHWC_OPS by default for CUDA builds.
