+name: Issue and enhancement template
+about: Used to report issues and request enhancements for llama.cpp
+title: "[User] Insert summary of your issue or enhancement.."
+labels: ''
+assignees: ''
+
+---
+
+# Prerequisites
+
+Please answer the following questions for yourself before submitting an issue.
+
+- [ ] I am running the latest code. Development is very rapid so there are no tagged versions as of now.
+- [ ] I carefully followed the [README.md](https://github.com/ggerganov/llama.cpp/blob/master/README.md).
+- [ ] I [searched using keywords relevant to my issue](https://docs.github.com/en/issues/tracking-your-work-with-issues/filtering-and-searching-issues-and-pull-requests) to make sure that I am creating a new issue that is not already open (or closed).
+- [ ] I reviewed the [Discussions](https://github.com/ggerganov/llama.cpp/discussions), and have a new bug or useful enhancement to share.
+
+# Expected Behavior
+
+Please provide a detailed written description of what you were trying to do, and what you expected `llama.cpp` to do.
+
+# Current Behavior
+
+Please provide a detailed written description of what `llama.cpp` did, instead. 
+
+# Environment and Context 
+
+Please provide detailed information about your computer setup. This is important in case the issue is not reproducible except for under certain specific conditions.
+
+* Physical (or virtual) hardware you are using, e.g. for Linux:
+
+`$ lscpu`
+
+* Operating System, e.g. for Linux:
+
+`$ uname -a`
+
+* SDK version, e.g. for Linux:
+
+```
+$ python3 --version
+$ make --version
+$ g++ --version
+```
+
+# Models
+
+* The LLaMA models are officially distributed by Facebook and will never be provided through this repository. See this [pull request in Facebook's LLaMA repository](https://github.com/facebookresearch/llama/pull/73/files) if you need to obtain access to the model data.
+* If your issue is with model conversion please verify the `sha256sum` of each of your `consolidated*.pth` and `ggml-model-XXX.bin` files to confirm that you have the correct model data files before logging an issue. [Latest sha256 sums for your reference](https://github.com/ggerganov/llama.cpp/issues/238).
+* If your issue is with model generation quality then please at least scan the following links and papers to understand the limitations of LLaMA models. This is especially important when choosing an appropriate model size and appreciating both the significant and subtle differences between LLaMA models and ChatGPT:
+  * LLaMA:
+    * [Introducing LLaMA: A foundational, 65-billion-parameter large language model](https://ai.facebook.com/blog/large-language-model-llama-meta-ai/)
+    * [LLaMA: Open and Efficient Foundation Language Models](https://arxiv.org/abs/2302.13971)
+  * GPT-3
+    * [Language Models are Few-Shot Learners](https://arxiv.org/abs/2005.14165)
+  * GPT-3.5 / InstructGPT / ChatGPT:
+    * [Aligning language models to follow instructions](https://openai.com/research/instruction-following)
+    * [Training language models to follow instructions with human feedback](https://arxiv.org/abs/2203.02155)
+
+# Failure Information (for bugs)
+
+Please help provide information about the failure if this is a bug. If it is not a bug, please remove the rest of this template.
+
+# Steps to Reproduce
+
+Please provide detailed steps for reproducing the issue. We are not sitting in front of your screen, so the more detail the better.
+
+1. step 1
+2. step 2
+3. step 3
+4. etc.
+
+# Failure Logs
+
+Please include any relevant log snippets or files. If it works under one configuration but not under another, please provide logs for both configurations and their corresponding outputs so it is easy to see where behavior changes.
+
+Also, please try to **avoid using screenshots** if at all possible. Instead, copy/paste the console output and use [Github's markdown](https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax) to cleanly format your logs for easy readability. e.g.

+@duncan-donut: I'm trying to figure out what kind of "support" you need for this script and why, exactly? Is there a question about how the code works that hasn't already been addressed in one or more comments below this ticket, or are we talking something else entirely like some sorta bugfixing job because your server setup is different from mine??
+I can understand if your site needs to be running smoothly and you need help with a fix of sorts but there should really be nothing wrong here that the code itself could not handle. And given that I'm getting reports about how it works perfectly well on some other servers, what exactly are we talking? A detailed report will do wonders in helping us get this resolved for ya quickly so please take your time and describe the issue(s) you see as clearly & concisely as possible!!
+@duncan-donut: I'm not sure if you have access to cPanel but you could try these instructions. It is worth a shot! Let me know how it goes (or what error message, exactly!) when/if ya give that code a go? [end of text]

+and sufficient RAM to load them. At the moment, memory and disk requirements are the same.
+
+| model | original size | quantized size (4-bit) |

 ### Interactive mode

 In this mode, you can always interrupt generation by pressing Ctrl+C and enter one or more lines of text which will be converted into tokens and appended to the current context. You can also specify a *reverse prompt* with the parameter `-r "reverse prompt string"`. This will result in user input being prompted whenever the exact tokens of the reverse prompt string are encountered in the generation. A typical use is to use a prompt which makes LLaMa emulate a chat between multiple users, say Alice and Bob, and pass `-r "Alice:"`.

 Here is an example few-shot interaction, invoked with the command
-```
-./main -m ./models/13B/ggml-model-q4_0.bin -t 8 -n 256 --repeat_penalty 1.0 --color -i -r "User:" \

-Bob: Hello. How may I help you today?
-User: Please tell me the largest city in Europe.
-Bob: Sure. The largest city in Europe is Moscow, the capital of Russia.

 ```
+
 Note the use of `--color` to distinguish between user input and generated text.

+### Instruction mode with Alpaca
+
+First, download the `ggml` Alpaca model into the `./models` folder:
+
+```
+# use one of these
+# TODO: add a script to simplify the download
+curl -o ./models/ggml-alpaca-7b-q4.bin -C - https://gateway.estuary.tech/gw/ipfs/QmUp1UGeQFDqJKvtjbSYPBiZZKRjLp8shVP9hT8ZB9Ynv1

+```
+
+Now run the `main` tool like this:
+
+```
+./main -m ./models/ggml-alpaca-7b-q4.bin --color -f ./prompts/alpaca.txt -ins
+```
+
+Sample run:

+### Obtaining and verifying the Facebook LLaMA original model and Stanford Alpaca model data
+
+* The LLaMA models are officially distributed by Facebook and will never be provided through this repository. See this [Pull Request in Facebook's LLaMA repository](https://github.com/facebookresearch/llama/pull/73/files) if you need to obtain access to the model data.
+
+* Please verify the sha256 checksums of all of your `consolidated*.pth` and corresponding converted `ggml-model-*.bin` model files to confirm that you have the correct model data files before creating an issue relating to your model files.
+
+The following command will verify if you have all possible latest files in your self-installed `./models` subdirectory:
+
+`sha256sum --ignore-missing -c SHA256SUMS` on Linux
+
+or
+
+`shasum -a 256 --ignore-missing -c SHA256SUMS` on macOS
+
+### Perplexity (Measuring model quality)
+
+You can pass `--perplexity` as a command line option to measure perplexity over the given prompt.  For more background,
+see https://huggingface.co/docs/transformers/perplexity.  However, in general, lower perplexity is better for LLMs.
+
+#### Measurements
+
+https://github.com/ggerganov/llama.cpp/pull/270 is the unofficial tracking page for now.  llama.cpp is measuring very well
+compared to the baseline implementations.  Quantization has a small negative impact to quality, but, as you can see, running
+13B at q4_0 beats the 7B f16 model by a significant amount.
+
+All measurements are done against wikitext2 test dataset (https://paperswithcode.com/dataset/wikitext-2), with default options (512 length context).
+Note that the changing the context length will have a significant impact on perplexity (longer context = better perplexity).
+```
+Perplexity - model options
+5.5985 - 13B, q4_0
+5.9565 - 7B, f16
+6.3001 - 7B, q4_1
+6.5949 - 7B, q4_0
+6.5995 - 7B, q4_0, --memory_f16
+```
+
+#### How to run
+
+1. Download/extract: https://s3.amazonaws.com/research.metamind.io/wikitext/wikitext-2-raw-v1.zip?ref=salesforce-research
+2. Run `./main --perplexity -m models/7B/ggml-model-q4_0.bin -f wiki.test.raw`
+3. Output:
+```
+Calculating perplexity over 655 chunks
+24.43 seconds per pass - ETA 4.45 hours
+[1]4.5970,[2]5.1807,[3]6.0382,...
+```
+And after 4.45 hours, you will have the final perplexity.

+### Docker
+
+#### Prerequisites
+* Docker must be installed and running on your system.
+* Create a folder to store big models & intermediate files (in ex. im using /llama/models)
+
+#### Images
+We have two Docker images available for this project:
+
+1. `ghcr.io/ggerganov/llama.cpp:full`: This image includes both the main executable file and the tools to convert LLaMA models into ggml and convert into 4-bit quantization.
+2. `ghcr.io/ggerganov/llama.cpp:light`: This image only includes the main executable file.
+
+#### Usage
+
+The easiest way to download the models, convert them to ggml and optimize them is with the --all-in-one command which includes the full docker image.
+
+ ```bash
+docker run -v /llama/models:/models ghcr.io/ggerganov/llama.cpp:full --all-in-one "/models/" 7B
+```
+
+On complete, you are ready to play!
+
+```bash
+docker run -v /llama/models:/models ghcr.io/ggerganov/llama.cpp:full --run -m /models/7B/ggml-model-q4_0.bin -p "Building a website can be done in 10 simple steps:" -n 512
+```
+
+or with light image:
+
+```bash
+docker run -v /llama/models:/models ghcr.io/ggerganov/llama.cpp:light -m /models/7B/ggml-model-q4_0.bin -p "Building a website can be done in 10 simple steps:" -n 512
+```

 ## Limitations

- We don't know yet how much the quantization affects the quality of the generated text
 - Probably the token sampling can be improved
 - The Accelerate framework is actually currently unused since I found that for tensor shapes typical for the Decoder,
-  there is no benefit compared to the ARM_NEON intrinsics implementation. Of course, it's possible that I simlpy don't
+  there is no benefit compared to the ARM_NEON intrinsics implementation. Of course, it's possible that I simply don't
  know how to utilize it properly. But in any case, you can even disable it with `LLAMA_NO_ACCELERATE=1 make` and the
  performance will be the same, since no BLAS calls are invoked by the current implementation
