      * MXFP4 support
      
      This implements the Open Compute Microscaling (MX) FP4 format
      as a tensor type with backend implementations focusing
      on mulmat and mulmatid on CPU, CUDA, and Metal.
      
      * Unit tests for MXFP4 support
      
      This exercises various operations and shapes on both CPU and GPU (if detected
      on the system)
      
      * cuda graph
      
      * unit test adjustments
      
      * cuda: optimize memory access
      
      Read 4 bytes at a time (8 elements) when performing mul_mat_vec_mxfp4
      
      * mac: fix crash on old macos versions
      
      cblas_sgemm is only supported on v13.3 and up, however bf16 is
      only supported on v14+ so we were falling back to ggml-blas and
      crashing on bf16 tensors.  Checking for the function being null
      seems to be the simplest way to condittionally avoid registering the
      backend.
      
      * server: Minimum context length for gptoss
      
      This model requires a minimum context length of 8192 to function
      effectively. Users can set higher values through all normal mechanisms
      but lower values will be silently reset.
      
      * ggml: Multiply by numParallel for gptoss sliding window
      
      When computing the graph size estimate, the context size is already
      multiplied by numParallel so estimates reflect that. However, since
      sliding window models use a smaller, fixed context size, they need
      to manually take numParallel into account.
      
      * gpt-oss integration
      
      includes harmony parser and thinking levels, etc.
      
      * fix sync
      
      * fix tests
      
      * fix lint

      model: support for mistral-small in the ollama runner · 6bd0a983
      Bruce MacDonald authored
      Mistral is a popular research lab making open source models. This updates
      the forward pass of llama architecture models to support both llama models
      and mistral models by accounting for additional metadata present in mistral
      models, and finding the correct dimensions for the output projection.
