Hi,

We are very pleased to announce the 0.11.0 version of TensorRT-LLM. This update includes:

Key Features and Enhancements

  • Supported very long context for LLaMA (see “Long context evaluation” section in examples/llama/README.md).
  • Low latency optimization
    • Added a reduce-norm feature which aims to fuse the ResidualAdd and LayerNorm kernels after AllReduce into a single kernel, which is recommended to be enabled when the batch size is small and the generation phase time is dominant.
    • Added FP8 support to the GEMM plugin, which benefits the cases when batch size is smaller than 4.
    • Added a fused GEMM-SwiGLU plugin for FP8 on SM90.
  • LoRA enhancements
    • Supported running FP8 LLaMA with FP16 LoRA checkpoints.
    • Added support for quantized base model and FP16/BF16 LoRA.
      • SQ OOTB (- INT8 A/W) + FP16/BF16/FP32 LoRA​
      • INT8/ INT4 Weight-Only (INT8 /W) + FP16/BF16/FP32 LoRA​
      • Weight-Only Group-wise + FP16/BF16/FP32 LoRA
    • Added LoRA support to Qwen2, see “Run models with LoRA” section in examples/qwen/README.md.
    • Added support for Phi-3-mini/small FP8 base + FP16/BF16 LoRA, see “Run Phi-3 with LoRA” section in examples/phi/README.md.

API Changes

  • [BREAKING CHANGE] trtllm-build command

    • Removed use_context_fmha_for_generation argument from trtllm-build command.
    • Removed strongly_typed argument from trtllm-build command.
    • The default value of max_seq_len reads from the HuggingFace mode config now.
  • C++ runtime
    • [BREAKING CHANGE] Renamed free_gpu_memory_fraction in ModelRunnerCpp to kv_cache_free_gpu_memory_fraction.

      • Updated the chat.py to support multi-turn conversation, allowing users to chat with a model in the terminal.
      • Fixed the fastapi_server.py and eliminate the need for mpirun in multi-GPU scenarios.

    • Introduction of SpeculativeDecodingMode.h to choose between different speculative decoding techniques.
    • Introduction of SpeculativeDecodingModule.h base class for speculative decoding techniques.

Infrastructure Changes

  • Base Docker image for TensorRT-LLM is updated to nvcr.io/nvidia/pytorch:24.05-py3.
  • Base Docker image for TensorRT-LLM backend is updated to nvcr.io/nvidia/tritonserver:24.05-py3.
  • The dependent TensorRT version is updated to 10.1.0.
  • The dependent CUDA version is updated to 12.4.1.
  • The dependent PyTorch version is updated to 2.3.1.
  • The dependent ModelOpt version is updated to v0.13.0.

Known Issues

  • In a conda environment on Windows, installation of TensorRT-LLM may succeed. However, when importing the library in Python, you may receive an error message of OSError: exception: access violation reading 0x0000000000000000. This issue is under investigation.

Currently, there are two key branches in the project:

  • The rel branch is the stable branch for the release of TensorRT-LLM. It has been QA-ed and carefully tested.
  • The main branch is the dev branch. It is more experimental.

We are updating the main branch regularly with new features, bug fixes and performance optimizations. The rel branch will be updated less frequently, and the exact frequencies depend on your feedback.

Thanks,
The TensorRT-LLM Engineering Team
