…19117) Experimenting with AI, my environment gets messy fast and it's not always easy to know what model my software is trying to load. This helps with troubleshooting. before: Error: { code = 400, message = "model not found", type = "invalid_request_error" } After: Error: { code = 400, message = "model 'toto' not found", type = "invalid_request_error" }
* ggml-cpu: split across kv for faster TG * simplify sinks application * add ref impl
…ml-org#19239) * jinja : add missing 'in' test to template engine (ggml-org#19004) The jinja template parser was missing the 'in' test from global_builtins(), causing templates using reject("in", ...), select("in", ...), or 'x is in(y)' to fail with "selectattr: unknown test 'in'". This broke tool-calling for Qwen3-Coder and any other model whose chat template uses the 'in' test. Added test_is_in supporting array, string, and object containment checks, mirroring the existing 'in' operator logic in runtime.cpp. Includes test cases for all three containment types plus reject/select filter usage.

* completion : simplify batch (embd) processing This commit simplifies the processing of embd by removing the for loop that currently exists which uses params.n_batch as its increment. This commit also removes the clamping of n_eval as the size of embd is always at most the size of params.n_batch. The motivation is to clarify the code as it is currently a little confusing when looking at this for loop in isolation and thinking that it can process multiple batches. * add an assert to verify n_eval is not greater than n_batch
* spec : fix the check-rate logic of ngram-simple * cont : refactor + fix checks
This commit adds a new python script that can be used to print tensors
information from a tensor in a safetensors model.
The motivation for this is that during model conversion work it can
sometimes be useful to verify the shape of tensors in the original
model. While it is possible to print the tensors when loading the model
this can be slow when working with larger models.
With this script it is possible to quickly query tensor shapes.
Example usage:
```console
(venv) $ ./scripts/utils/tensor-info.py --help
usage: tensor-info.py [-h] [-m MODEL_PATH] [-l] [tensor_name]
Print tensor information from a safetensors model
positional arguments:
tensor_name Name of the tensor to inspect
options:
-h, --help show this help message and exit
-m MODEL_PATH, --model-path MODEL_PATH
Path to the model directory (default: MODEL_PATH environment variable)
-l, --list List unique tensor patterns in the model (layer numbers replaced with #)
```
Listing tensor names:
```console
(venv) $ ./scripts/utils/tensor-info.py -m ~/work/ai/models/google/embeddinggemma-300m -l
embed_tokens.weight
layers.#.input_layernorm.weight
layers.#.mlp.down_proj.weight
layers.#.mlp.gate_proj.weight
layers.#.mlp.up_proj.weight

layers.#.self_attn.o_proj.weight
layers.#.self_attn.q_norm.weight
layers.#.self_attn.q_proj.weight
layers.#.self_attn.v_proj.weight
norm.weight
```
Printing a specific tensor's information:
```console
(venv) $ ./scripts/utils/tensor-info.py -m ~/work/ai/models/google/embeddinggemma-300m layers.0.input_layernorm.weight
Tensor: layers.0.input_layernorm.weight
File: model.safetensors

…#19324) * model: (qwen3next) correct vectorized key_gdiff calculation * move transpose to outside of loop
* debug: make common_debug_print_tensor readable * editorconfig
* bench : update script * benches : update numbers
…org#19281) Write out a 2-bit code per block and avoid loading the mask when it matches these two common cases. Apply this optimization when the mask is relatively large (i.e. prompt processing).
This commit addresses the TODO in llama-sampling.h to rename that header and the implementation to llama-sampler.
* metal : skip loading all-zero mask * cont : minor
* vulkan: make FA mask/softcap enables spec constants * don't specialize for sinks * bump timeout a little bit
…gml-org#19376) The cpu and cuda backends use fp16 for the VKQ accumulator type, this change does the same for vulkan. This helps particularly with large head sizes which are very register-limited. I tried this for the coopmat1 path and it slowed down a bit. I didn't try for scalar. I applied the softmax bias that the cuda backend uses to avoid overflow, although I was not able to reproduce the original bug without it.
