…ggml-org#21592) * fix: free ctx_copy in ggml_opt_free to plug per-training-session leak ggml_opt_alloc populates opt_ctx->ctx_copy via a free+init pair every time the allocated graph shape changes. The last ctx_copy from the final ggml_opt_alloc call survives until ggml_opt_free is invoked, but ggml_opt_free was only freeing ctx_static and ctx_cpu, never ctx_copy. Each opt_ctx lifetime therefore leaks the final per-batch context — ~900 KB for a typical GNN training session in sindarin-pkg-tensor, surfaced via AddressSanitizer. ctx_copy is nullptr-initialized and ggml_free() handles NULL safely, so the new release is guard-free. * Update ggml/src/ggml-opt.cpp Co-authored-by: Johannes Gäßler <johannesg@5d6.de> --------- Co-authored-by: realorko <realorko@nowhere.com> Co-authored-by: Johannes Gäßler <johannesg@5d6.de>

actions/labeler@v6 removed the `all:` / `any:` composition keys.
The `server/webui` and `server` entries used `all:` to combine
`any-glob-to-any-file` with negated `all-globs-to-all-files`,
which now errors on every PR with:
Unknown config options were under "changed-files": all
Flatten both entries to a single `any-glob-to-any-file`. PRs
touching both webui and other server files will now receive both
labels instead of only `server/webui`.

* sycl : add flash-attn support for head size 512 This patch extends the SYCL Flash Attention implementation to support head sizes (DKQ/DV) of 512. Changes: - Added DKQ/DV 512 cases to both tile and vector Flash Attention kernels. - Updated kernel selection logic to allow vector kernels for head sizes up to 512 (previously 256). - Removed unused/redundant AMD and RDNA-specific configuration functions in `fattn-tile.hpp`. - Refactored `ggml_backend_sycl_buffer_init_tensor` to use a switch statement for clearer tensor extra buffer initialization. - Added necessary template instances for the new 512 head size across various quantization types. * remove defunct mxfp4 reorder from setting buffer type

…lf-filtering (ggml-org#21623) * feat: jinja engine improvements for reka-edge Port three Jinja engine improvements needed for the reka-edge model: 1. Python-style string repetition ("ab" * 3 → "ababab") 2. ensure_ascii=true support for tojson filter (escapes non-ASCII to \uXXXX) 3. int() builtin on value_int_t (identity, needed for Reka Edge template) * fix: escape invalid utf8 bytes when ensure_ascii=true The json_ensure_ascii_preserving_format function does not correctly handle an edge case where if UTF-8 parsing fails, it adds the non-ascii character back to the output as a raw byte. This commit fixes that by adding the unicode standard replacement character \\ufffd to the output instead. This is the standard behavior for various programming languages like Python, Rust, Go, etc. * chore: address PR comments 1. Add todo comment for supporting string repetition for array/tuples 2. Add support for float identity operation 3. Move invalid ascii test case to test_fuzzing * chore: accept suggestion for common/jinja/value.cpp Co-authored-by: Sigbjørn Skjæret <sigbjorn.skjaeret@scala.com> --------- Co-authored-by: Sigbjørn Skjæret <sigbjorn.skjaeret@scala.com>

* requirements : update transformers to 5.5.0 This commit updates the transformers dependency to version 5.5.0. The motivation for this is that transformers 5.5.0 includes support for Gemma4 and is required to be able to convert Gemma4 models. This is also causing issues for user of gguf-my-repo. Refs: https://huggingface.co/spaces/ggml-org/gguf-my-repo/discussions/202 * fix huggingface_hub version * set version of transformers to 5.5.0 * convert : add ty ignore directives to convert_hf_to_gguf.py This commit adds `ty: ignore` directives to transformers tokenizers field/methods to avoid type check errors. There might be better ways to handle this and perhaps this can be done in a follow up commit. The motivation for this is that it looks like in transformers 5.5.0 AutoTokenizer.from_pretrained can return generic tokenizer types or None and the type checker now produces an error when the conversion script accesses field like tokenizer.vocab. * convert : add ty ignore to suppress type check errors * convert : remove incorrect type ignores * convert : fix remaining python checks I was running a newer version of ty locally but I've switched to version 0.0.26 which is what CI uses and I was then able to reproduce the errors. Sorry about the noise. * update transformers version to 5.5.1

This allows using pinned memory instead of pageable memory for CUDA. Fix compilation errors. * partial Qwen 3 Next support * Fix qwen3 30b (#8) * Fix crash with Qwen-30B-A3B Q4_0 Qwen-30B-A3B Q4_0 has an intermediate dimension of 768. Using a granularity of 256 forces an uneven split between GPUs, which is not supported by the current implementation. * Decide block size based on tensor quantization type * Fix crashes due to KV cache serialization (#9) KV cache serialization requires non-zero offsets on the tensor. Add support in the meta backend to set/get a tensor with a non-zero offset. * metal : fix build (#7) * static memory allocations, fix usage count * fix tensor granularity * more even memory distribution * use BF16 for allreduce * rebase fixup * better error message for unsupported architectures * Fix device mismatch during scatter of allReduce. (#11) There is a mismatch between the dst buffer device and the backend device, causing the use of sync copies * Enable the previous allreduce implementation. It is better in both perf and stability (#12) * delay AllReduce for Moe for less I/O * build : clean-up compile warnings * backend : move most of the meta backend API to ggml-backend-impl.h * cont : hide unused public API in the implementation * llama : use llama_device + remove ggml_backend_dev_is_meta() * ggml-backend : remove unused alloc include * minor : remove regex include * ggml : introduce ggml-ext.h for staging new APIs * rebase fixup * fix tests * llama : more robust logic for determining Meta devices (#16) * llama : more robust logic for determining Meta devices * cont : fix devs size check Co-authored-by: Johannes Gäßler <johannesg@5d6.de> * cont : fix log type Co-authored-by: Johannes Gäßler <johannesg@5d6.de> --------- Co-authored-by: Johannes Gäßler <johannesg@5d6.de> * disable roundtrip for meta backend * fix arch selection * Qwen 3.5 support * fix Gemma 4 MoE * fix OpenVino, SYCL * fix test-llama-archs for CPU-only builds * Fix Qwen 3.5 MoE * disable meta backend tests for WebGPU * tests : filter CPU-based devices from the Meta backend tests (#17) * meta : formatting, naming, indentation (#18) * formatting : llama-model.cpp * formatting : ggml-ext.h * formatting : ggml-backend-meta.cpp * meta : add TODO * add documentation * better error messages * fix GPT-OSS --------- Co-authored-by: Carl Philipp Klemm <carl@uvos.xyz> Co-authored-by: Gaurav Garg <gaugarg@nvidia.com> Co-authored-by: Georgi Gerganov <ggerganov@gmail.com>
