* requirements: relax torch~=2.6.0 to torch>=2.6.0 for convert_hf_to_gguf
The ~=2.6.0 operator resolves to >=2.6.0, <2.7.0, which fails on
PyPI for platform/CPython combinations where 2.6.x is not present.
The accompanying comment already says 'PyTorch 2.6.0 or later', so
the looser >=2.6.0 matches the documented intent and unblocks
pip install -r requirements/requirements-convert_hf_to_gguf.txt.
Fixes#23408
* requirements: bump torch floor to 2.11.0 per maintainer
* requirements: pin torch to ==2.11.0 per project policy
* requirements: pin mtmd torch and torchvision to 2.11.0/0.26.0 per project policy
* requirements: suppress check_requirements pin warning on mtmd
The check_requirements script flags '==' on lines in files matched by
*/**/requirements*.txt. Append the documented suppression comment to the
pinned torch and torchvision lines (and to the s390x platform marker lines)
so the check passes while keeping the pins required by project policy.
* ty: silence Tensor/Module union check on model[0].auto_model
With torch 2.11.0 stubs, nn.Sequential.__getitem__ now returns
Tensor | Module rather than Module, so model[0].auto_model fails ty
on the SentenceTransformer code path. The runtime behavior is
unchanged because SentenceTransformer always wraps a Module at
index 0. Adding a targeted unresolved-attribute ignore keeps the
type-check green without altering behavior. A follow-up issue
tracks typing the variable explicitly.
- change `k_copy_src1_to_contiguous` so that uses a precomputed contiguous mapping where all rows "owned" by an expert are in one slice with a know starts and ends
- switch the `O(n_as * n_routed_rows)` contraption to a counting sort-based procedure with `O(n_as + n_routed_rows)` complexity
* SYCL: add BF16 to DMMV kernel path for ~4x token generation speedup
BF16 models had no dedicated token generation kernel — they fell through
to the generic full-GEMM path, resulting in ~14% memory bandwidth
utilization on Intel Arc GPUs. This adds BF16 support to the DMMV
(dequantize mul-mat-vec) path, matching the existing F16 implementation.
Fixes#20478
* SYCL: fix BF16 DMMV out-of-bounds when ncols % 64 != 0
The qk=1 kernel (used for F16 and BF16) iterates with stride
2*GGML_SYCL_DMMV_X (= 64 on Intel targets where WARP_SIZE=16). When
ncols is a multiple of DMMV_X (32) but not of 2*DMMV_X (64), the last
warp iteration accesses elements at col >= ncols, producing NaN for the
final row and wrong values for interior rows.
Fix: tighten can_use_dequantize_mul_mat_vec to require ne[0] %
(2*DMMV_X) == 0 for F16/BF16 types, and update the ASSERT in the BF16
launcher to match. Quantized types use block-structured kernels with
different access patterns and keep the existing DMMV_X check.
Verified: test-backend-ops MUL_MAT passes 913/913 on Intel Arc Pro B70.
Previously failing: m=128/129 n=1 k=1056 cases (NaN and ERR > 0.0005).

* vulkan: fuse snake activation (mul, sin, sqr, mul, add)
Add snake.comp shader with F32 / F16 / BF16 pipelines and
ggml_vk_snake_dispatch_fused. The matcher recognizes the naive 5 op
decomposition emitted by audio decoders (BigVGAN, Vocos) for snake
activation y = x + sin(a*x)^2 * inv_b and rewrites it to a single
elementwise kernel.
test_snake_fuse from the CUDA PR now also compares CPU naive vs
Vulkan fused across F32 / F16 / BF16.
* vulkan: address jeffbolznv review for fused snake activation
Rename T / C to ne0 / ne1 in the shader and push constants to match
the standard naming convention used across the Vulkan backend.
Tighten ggml_vk_can_fuse_snake: require x and dst to be contiguous
(the shader uses idx = i0 + i1 * ne0) and require a / inv_b to be
tightly packed on the broadcast dim (the shader reads data_a[i1]).
* vulkan: tighten snake fusion type checks for all operands (address jeffbolznv review)
* vulkan: reject snake fusion when ne[2] or ne[3] > 1 (address jeffbolznv review)
* vulkan: address 0cc4m review for fused snake activation
snake.comp is renamed to follow the ggml DATA_A_* / A_TYPE convention.
A_TYPE now applies to the activation tensor data_a instead of the
broadcast multiplier, and the bindings become data_a (A_TYPE), data_b
(float), data_c (float) and data_d (D_TYPE). A header at the top of
the shader maps each buffer to its role in y = x + sin(b * x)^2 * c.
On the C++ side, ggml_vk_can_fuse_snake reuses the existing snake_pattern
constant instead of duplicating the op list, sin_node is extracted as a
named local alongside the other chain nodes, and the broadcast operands
a and inv_b are now required to be GGML_TYPE_F32 to match the hardcoded
float bindings on data_b and data_c (the previous a->type == x->type
would silently reject any future BF16 or F16 chain once the supports_op
gate for SIN / SQR is lifted). ggml_vk_snake_dispatch_fused gets an
explicit GGML_TYPE_F32 case and GGML_ABORT on default in place of the
silent f32 fallback, and a stale comment about data_a[i1] / data_inv_b[i1]
is refreshed to match the new binding names.

* metal : optimize concat kernel with row batching for small widths

* tests : clean-up
* tests : refactor CPY shape tests to use dimension permutations
Replace 75 hardcoded test cases with a loop over permutations of

Covers F32, F16, and Q4_0 (when both src and dst ne0 == 32).

The destroy() function in server_context_impl only cleaned up the main
model and context (via llama_init.reset()) but did not free the speculative
decoder (spec), draft context (ctx_dft), or draft model (model_dft).
For MTP (Multi-Token Prediction) models, ctx_dft holds GPU-allocated
resources (KV cache, compute buffers) that are not freed when entering
the sleeping state. On each sleep/resume cycle, new resources are
allocated without the old ones being freed, leading to a VRAM leak
that eventually crashes the server with out-of-memory errors.
Fix by explicitly resetting spec, ctx_dft, and model_dft in destroy()
before resetting llama_init, ensuring proper cleanup order to avoid
use-after-free.

* vocab : add Carbon-3B (HybridDNATokenizer) support
Adds a new BPE pre-type LLAMA_VOCAB_PRE_TYPE_CARBON for the
HybridDNATokenizer used by HuggingFaceBio/Carbon-{500M,3B,8B}.
The base BPE is Qwen3-4B-Base's; what differs is that text inside
<dna>...</dna> regions is chunked into fixed 6-mers (right-padded
with 'A' on the trailing partial), and any base outside ACGT maps
to <oov>.
* src/llama-vocab.{h,cpp}: new pre-type, dispatched from
llm_tokenizer_bpe_session::tokenize.
* src/llama-vocab-carbon.h: pure helpers (tokenize_carbon,
emit_dna_kmers) factored out for unit testing — no llama_vocab
dependency, vocab access goes through a std::function.
* conversion/base.py: detect HybridDNATokenizer by class name in
get_vocab_base_pre (chktxt collides with Qwen3 base since it
has no <dna>), and pass trust_remote_code=True in get_vocab_base
so the custom tokenizer class can load.
* tests/test-tokenizer-carbon.cpp: 12 cases covering single 6-mer,
multi 6-mer, lowercase, invalid base -> <oov>, partial k-mer
right-pad, mixed text+DNA, empty <dna></dna>, unterminated <dna>,
two regions, vocab miss.
* vocab : align Carbon-3B changes with llama.cpp conventions
* Fold tokenize_carbon + emit_dna_kmers inline into
llm_tokenizer_bpe_session (drop src/llama-vocab-carbon.h),
matching how every other tokenizer keeps its helpers inside
llama-vocab.cpp.
* Replace the standalone unit test with the conventional
test-tokenizer-0 row backed by models/ggml-vocab-carbon.gguf
(vocab-only conversion) + .inp/.out fixtures covering single
6-mer, multi 6-mer, lowercase, invalid base -> <oov>, partial
right-pad, mixed text+DNA, empty <dna></dna>, unterminated <dna>,
two regions.
* Register "carbon" in convert_hf_to_gguf_update.py's model list
(pointing at HuggingFaceBio/Carbon-3B) and teach both
AutoTokenizer call sites in the updater to pass
trust_remote_code=True for it, matching how t5 is special-cased.
* vocab : move Carbon dispatch to _set_vocab_carbon + LlamaModel branch
Refactor the conversion-side changes to follow the per-tokenizer-family
convention used by _set_vocab_qwen, _set_vocab_interns1, _set_vocab_glm,
etc. instead of conditionalising the shared get_vocab_base /
get_vocab_base_pre paths.
* conversion/base.py: add _set_vocab_carbon — self-contained, loads
with trust_remote_code=True so HybridDNATokenizer's merged Qwen3 + DNA
vocab is visible, writes tokenizer.ggml.pre = "carbon" directly.
* conversion/llama.py: branch in LlamaModel.set_vocab on
tokenizer_config.json["tokenizer_class"] == "HybridDNATokenizer" and
dispatch to _set_vocab_carbon. Same precedent as conversion/bert.py
(tokenizer_class branch between BertTokenizer / RobertaTokenizer) and
conversion/phi.py.
* conversion/base.py: revert the conditional in get_vocab_base and the
class-name short-circuit in the auto-generated get_vocab_base_pre.
* tests : expand ggml-vocab-carbon.gguf fixtures with model-card examples
Add 6 cases from the Carbon-3B model card on top of the existing edge
coverage: the unterminated basic-completion prompt, the closed 33-bp
example, the metadata-conditioned prompt (with <vertebrate_mammalian>
and <protein_coding_region> which BPE-decompose since they are not in
the vocab), the documented anti-pattern of raw DNA without <dna> tags,
and the two likelihood-scoring examples. Brings the suite to 19 cases.
* vocab : promote HybridDNATokenizer to its own LLAMA_VOCAB_TYPE
Refactor per upstream review:
> This should be its own tokenizer model, ie. carbonhybriddna instead
> of gpt2 and not carbon pre-tokenizer. That way you can keep the
> correct pre-tokenizer, in case that ever changes.
Previously the tokenizer was modelled as LLAMA_VOCAB_TYPE_BPE plus a
new LLAMA_VOCAB_PRE_TYPE_CARBON, which (a) put a CARBON-specific
branch inside llm_tokenizer_bpe_session::tokenize (only existing
pre-types differ in regex, not dispatch logic), and (b) conflated
"hybrid DNA tokenization" with "Qwen3 BPE pre-tokenizer".
This change moves it to its own vocab type, peer to PLAMO2, with the
GGUF model name matching the HF tokenizer class (HybridDNATokenizer):
* include/llama.h: new LLAMA_VOCAB_TYPE_HYBRIDDNA = 7.
* src/llama-vocab.cpp: new llm_tokenizer_hybriddna + session that
owns std::unique_ptr<llm_tokenizer_bpe> for non-<dna> text and
routes raw text through a DNA-aware splitter; wired into
init_tokenizer, tokenize, type_name, byte_to_token, and the
BPE-style token_to_piece case (DNA k-mers + <dna>/</dna>/<oov>
are pure ASCII, so byte-level BPE decoding handles them).
LLAMA_VOCAB_TYPE_HYBRIDDNA gets its own branch in the vocab-type
config block alongside SPM/WPM/UGM/RWKV, where pre_type is set
to QWEN2 and the matching add_space_prefix / escape_whitespaces /
clean_spaces flags are applied — mirroring qwen2's BPE path so
byte-level BPE merging stays bit-identical to the Python
reference for non-DNA text.
* src/llama-vocab.h: drop the short-lived LLAMA_VOCAB_PRE_TYPE_CARBON.
* conversion/base.py: _set_vocab_hybriddna writes
tokenizer.ggml.model = "hybriddna" (no separate pre).
* conversion/llama.py: dispatch on tokenizer_class ==
"HybridDNATokenizer" same as bert.py / phi.py do.
* models/ggml-vocab-hybriddna.gguf{,.inp,.out}: renamed fixture +
regenerated metadata.
* convert_hf_to_gguf_update.py: drop the stale chkhsh entry and
trust_remote_code special-case (no longer needed since dispatch
is now class-name driven, not chkhsh).
Verified end-to-end against HuggingFaceBio/Carbon-{500M,3B,8B}:
tokenization is bit-identical to the Python HybridDNATokenizer for
all 19 test fixtures plus the model-card metadata-conditioned
prompt; greedy completion produces the same DNA continuation as
the Python reference; spec-dec with 500M as draft for 8B still
works.
* vocab : relax llm_tokenizer_bpe assert to allow HYBRIDDNA
* vocab : drop llm_tokenizer_bpe vocab-type assert
* vocab : write tokenizer.ggml.pre for HYBRIDDNA, share BPE dispatch
* vocab : assert BPE or HYBRIDDNA in llm_tokenizer_bpe
* vocab : annotate #endif with PRETOKENIZERDEBUG
* vocab : drop local hybriddna fixture (moves to ggml-org/vocabs)
* deduplicate
* simplify
* simplify
