LostRuins ConcedoandGitHub 59e991c23c Fixes Qwen2.5VL segfault during inference with https://github.com/ggml-org/llama.cpp/pull/12402 as has_qwen2vl_merger migration was incomplete (#13133) 2025-04-27 12:43:37 +02:00
LostRuins ConcedoandGitHub 6390a998bf tts : add guide tokens support (#11186)
* Added the ability to use guide tokens for OuteTTS, greatly improving TTS recitation accuracy over long input sequences.

* applied linting suggestions, updated to latest llama_vocab changes, added a safety check, added newline to guide token start

20a68a7030 ggml : add ggml_row_size() (fixes llama out of space) (#4461)
* Fixes "Not enough space in the context's memory pool" encountered on certain models, which seems to be caused by some imprecision related to the automatic casting of floating point values

* do not cast to size_t, instead just use doubles

* ggml : add ggml_row_size(), deprecate ggml_type_sizef()

* ggml : fix row size compute to avoid overflows

* tests : fix sizey -> sizez

bbef28218f Possible solution to allow K-quants on models with n_vocab!=32000 (#2148)
* This allows LLAMA models that were previously incompatible with K quants to function mostly as normal. This happens when a model has a vocab != 32000, e.g 32001 which means it's not divisible by 256 or 64. Since the problematic dimensions only apply for `tok_embeddings.weight` and `output.weight` (dimentions 4096 x n_vocab), we can simply quantize these layers to Q8_0 whereas the majority of the hidden layers are still K-quanted since they have compatible dimensions.

* Fix indentation

* As an alternative, to avoid failing on Metal due to lack of Q8_0 support, instead quantize tok_embeddings.weight to Q4_0 and retain output.weight as F16. This results in a net gain of about 55mb for a 7B model compared to previous approach, but should minimize adverse impact to model quality.

LostRuinsandGitHub d5b111f53d Clblast fixes + enhancements to save VRAM and offload more layers (#1675)
* Use events instead of clFinish, where possible

* OpenCL: Don't load gpu layers into RAM, add mul_f32 kernel

* Reduce queueing overhead for contiguous tensors by using single mul kernel call

* Adapt to #1612 cl_mem malloc changes

* Reduce code duplication between cuda and opencl branches

* Improve implementation

* Clblast fixes + enhancements to save VRAM:

1. Change all Clblast buffers to CL_MEM_READ_WRITE, as the pool malloc currently doesn't properly handle them.
2. When recycling buffers in pool malloc, always assign the SMALLEST available buffer that fits, instead of the FIRST available buffer
3. When failing to recycle a buffer in pool malloc (all too small), instead recycle the largest available free buffer by resizing it.

* change max value size_t to use limits

* removed flags from the CL pool malloc, apply code tidying suggestions.
