Summary of major features and improvements  

  • More GenAI coverage and framework integrations to minimize code changes

    • New models supported: Phi-4 Mini, Jina CLIP v1, and Bce Embedding Base v1.
    • OpenVINO™ Model Server now supports VLM models, including Qwen2-VL, Phi-3.5-Vision, and InternVL2.
    • OpenVINO GenAI now includes image-to-image and inpainting features for transformer-based pipelines, such as Flux.1 and Stable Diffusion 3 models, enhancing their ability to generate more realistic content.
    • Preview: AI Playground now utilizes the OpenVINO Gen AI backend to enable highly optimized inferencing performance on AI PCs.

  • Broader LLM model support and more model compression techniques

    • Reduced binary size through optimization of the CPU plugin and removal of the GEMM kernel.
    • Optimization of new kernels for the GPU plugin significantly boosts the performance of Long Short-Term Memory (LSTM) models, used in many applications, including speech recognition, language modeling, and time series forecasting.
    • Preview: Token Eviction implemented in OpenVINO GenAI to reduce the memory consumption of KV Cache by eliminating unimportant tokens. This current Token Eviction implementation is beneficial for tasks where a long sequence is generated, such as chatbots and code generation.
    • NPU acceleration for text generation is now enabled in OpenVINO™ Runtime and OpenVINO™ Model Server to support the power-efficient deployment of VLM models on NPUs for AI PC use cases with low concurrency.

  • More portability and performance to run AI at the edge, in the cloud, or locally.

    • Support for the latest Intel® Core™ processors (Series 2, formerly codenamed Bartlett Lake), Intel® Core™ 3 Processor N-series and Intel® Processor N-series (formerly codenamed Twin Lake) on Windows.
    • Additional LLM performance optimizations on Intel® Core™ Ultra 200H series processors for improved 2nd token latency on Windows and Linux.
    • Enhanced performance and efficient resource utilization with the implementation of Paged Attention and Continuous Batching by default in the GPU plugin.
    • Preview: The new OpenVINO backend for Executorch will enable accelerated inference and improved performance on Intel hardware, including CPUs, GPUs, and NPUs.

Support Change and Deprecation Notices

  • Discontinued in 2025:

    • Runtime components:

      • The OpenVINO property of Affinity API is no longer available. It has been replaced with CPU binding configurations (ov::hint::enable_cpu_pinning).

    • Tools:

      • The OpenVINO™ Development Tools package (pip install openvino-dev) is no longer available for OpenVINO releases in 2025.
      • Model Optimizer is no longer available. Consider using the new conversion methods instead. For more details, see the model conversion transition guide.
      • Intel® Streaming SIMD Extensions (Intel® SSE) are currently not enabled in the binary package by default. They are still supported in the source code form.
      • Legacy prefixes: l_, w_, and m_ have been removed from OpenVINO archive names.

    • OpenVINO GenAI:

      • StreamerBase::put(int64_t token)
      • The Bool value for Callback streamer is no longer accepted. It must now return one of three values of StreamingStatus enum.
      • ChunkStreamerBase is deprecated. Use StreamerBase instead.
    • NNCF create_compressed_model() method is now deprecated. nncf.quantize() method is recommended for Quantization-Aware Training of PyTorch and TensorFlow models.
    • OpenVINO Model Server (OVMS) benchmark client in C++ using TensorFlow Serving API.
  • Deprecated and to be removed in the future:
    • openvino.Type.undefined is now deprecated and will be removed with version 2026.0. openvino.Type.dynamic should be used instead.
    • APT & YUM Repositories Restructure: Starting with release 2025.1, users can switch to the new repository structure for APT and YUM, which no longer uses year-based subdirectories (like “2025”). The old (legacy) structure will still be available until 2026, when the change will be finalized. Detailed instructions are available on the relevant documentation pages:
    • OpenCV binaries will be removed from Docker images in 2026.
    • Ubuntu 20.04 support will be deprecated in future OpenVINO releases due to the end of standard support.
    • “auto shape” and “auto batch size” (reshaping a model in runtime) will be removed in the future. OpenVINO’s dynamic shape models are recommended instead.
    • MacOS x86 is no longer recommended for use due to the discontinuation of validation. Full support will be removed later in 2025.
    • The openvino namespace of the OpenVINO Python API has been redesigned, removing the nested openvino.runtime module. The old namespace is now considered deprecated and will be discontinued in 2026.0.
