2023-07-28readme : fix the description of the Tail free sampling (TFS) method (#2431)Weird Constructor
2023-07-25main : add `--in-prefix-bos` to prefix BOS to user inputs; keep EOS (#2304)Xiao-Yong Jin
* add `--in-prefix-bos` to prefix BOS to user inputs; keep EOS The BOS precedes the string specified by `--in-prefix`. Model generated EOS is now kept in the context. It provides a way to strictly following the prompt format used in Llama-2-chat. The EOS handling also benefits some existing finetunes that uses EOS to mark the end of turn. * examples/common: move input_prefix_bos to other bools
2023-07-23llama : add grammar-based sampling (#1773)Evan Jones

2023-07-15llama : add custom RoPE (#2054)Xiao-Yong Jin
* Implement customizable RoPE The original RoPE has pre-defined parameters theta_i = 10000^(−2(i−1)/d), for i in [1, 2, ..., d/2] Our customizable RoPE, ggml_rope_custom_inplace, uses theta_i = scale * base^(−2(i−1)/d), for i in [1, 2, ..., d/2] with the default matches the original scale = 1.0 base = 10000 The new command line arguments --rope-freq-base --rope-freq-scale set the two new RoPE parameter. Recent researches show changing these two parameters extends the context limit with minimal loss. 1. Extending Context to 8K kaiokendev https://kaiokendev.github.io/til#extending-context-to-8k 2. Extending Context Window of Large Language Models via Positional Interpolation Shouyuan Chen, Sherman Wong, Liangjian Chen, Yuandong Tian https://arxiv.org/abs/2306.15595 3. NTK-Aware Scaled RoPE allows LLaMA models to have extended (8k+) context size without any fine-tuning and minimal perplexity degradation. https://www.reddit.com/user/bloc97 https://www.reddit.com/r/LocalLLaMA/comments/14lz7j5/ntkaware_scaled_rope_allows_llama_models_to_have/ For the bold, try adding the following command line parameters to your favorite model: -c 16384 --rope-freq-base 80000 --rope-freq-scale 0.5 * ggml-metal: fix custom rope * common: fix argument names in help * llama: increase MEM_REQ_EVAL for MODEL_3B It avoids crashing for quantized weights on CPU. Better ways to calculate the required buffer size would be better. * llama: make MEM_REQ_EVAL depend on n_ctx * server: use proper Content-Type in curl examples Without the header Content-Type: application/json, curl will POST with Content-Type: application/x-www-form-urlencoded Though our simple server doesn't care, the httplib.h used has a limit with CPPHTTPLIB_FORM_URL_ENCODED_PAYLOAD_MAX_LENGTH 8192 With Content-Type: application/json, we can send large json data. * style : minor fixes, mostly indentations * ggml : fix asserts --------- Co-authored-by: Georgi Gerganov <ggerganov@gmail.com>

2023-06-06main: add the possibility to open the prompt cache read-only (#1640)Willy Tarreau
The prompt cache constitutes a nice speed up when using the same prompt prefix across multiple evaluations, but when using it, it will also be updated, which is not always desirable. One use case is to have a large prompt containing some context and usage rules, and a second part containing variable data of the problem being studied. In this case it's desirable to be able to save the first part once, and to always reuse it as-is without updating it with the second part. The new argument --prompt-cache-ro enables this read-only mode on the prompt cache. The prompt's contents that match the cache are loaded from the cache but the rest is not modified. This allowed to reduce a total analysis time from 112s to 49.7s here, without having to backup and restore a copy of the prompt, which takes significant time at 500 MB.

* Work around for recalculating logits in cached prompts
2023-05-28Only show -ngl option when relevant + other doc/arg handling updates (#1625)Kerfuffle
1. Add a `LLAMA_SUPPORTS_GPU_OFFLOAD` define to `llama.h` (defined when compiled with CLBlast or cuBLAS) 2. Update the argument handling in the common example code to only show the `-ngl`, `--n-gpu-layers` option when GPU offload is possible. 3. Add an entry for the `-ngl`, `--n-gpu-layers` option to the `main` and `server` examples documentation 4. Update `main` and `server` examples documentation to use the new style dash separator argument format 5. Update the `server` example to use dash separators for its arguments and adds `-ngl` to `--help` (only shown when compiled with appropriate support). It will still support `--memory_f32` and `--ctx_size` for compatibility. 6. Add a warning discouraging use of `--memory-f32` for the `main` and `server` examples `--help` text as well as documentation. Rationale: https://github.com/ggerganov/llama.cpp/discussions/1593#discussioncomment-6004356
2023-05-25Some improvements to loading the session with --prompt-cache (#1550)Kerfuffle
Improvements to loading the session with `--prompt-cache` in the `main` example. 1. Fix an issue where the `--seed` parameter was ignored when loading a cached prompt. 2. When loading a cached prompt, you previously had to specify the saved prompt (or a prefix of it) again. This pull changes that behavior to default to the prompt that was cached if a prompt wasn't specified by the user.
