-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-We as members, contributors, and leaders pledge to make participation in our
-community a harassment-free experience for everyone, regardless of age, body
-size, visible or invisible disability, ethnicity, sex characteristics, gender
-identity and expression, level of experience, education, socio-economic status,
-nationality, personal appearance, race, caste, color, religion, or sexual
-identity and orientation.
-
-We pledge to act and interact in ways that contribute to an open, welcoming,
-diverse, inclusive, and healthy community.
-
-## Our Standards
-
-Examples of behavior that contributes to a positive environment for our
-community include:
-
-* Demonstrating empathy and kindness toward other people
-* Being respectful of differing opinions, viewpoints, and experiences
-* Giving and gracefully accepting constructive feedback
-* Accepting responsibility and apologizing to those affected by our mistakes,
-  and learning from the experience
-* Focusing on what is best not just for us as individuals, but for the overall
-  community
-
-Examples of unacceptable behavior include:
-
-* The use of sexualized language or imagery, and sexual attention or advances of
-  any kind
-* Trolling, insulting or derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or email address,
-  without their explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Enforcement Responsibilities
-
-Community leaders are responsible for clarifying and enforcing our standards of
-acceptable behavior and will take appropriate and fair corrective action in
-response to any behavior that they deem inappropriate, threatening, offensive,
-or harmful.
-
-Community leaders have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, and will communicate reasons for moderation
-decisions when appropriate.
-
-## Scope
-
-This Code of Conduct applies within all community spaces, and also applies when
-an individual is officially representing the community in public spaces.
-Examples of representing our community include using an official e-mail address,
-posting via an official social media account, or acting as an appointed
-representative at an online or offline event.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported to the community leaders responsible for enforcement at
-feedback@huggingface.co.
-All complaints will be reviewed and investigated promptly and fairly.
-
-All community leaders are obligated to respect the privacy and security of the
-reporter of any incident.
-
-## Enforcement Guidelines
-
-Community leaders will follow these Community Impact Guidelines in determining
-the consequences for any action they deem in violation of this Code of Conduct:
-
-### 1. Correction
-
-**Community Impact**: Use of inappropriate language or other behavior deemed
-unprofessional or unwelcome in the community.
-
-**Consequence**: A private, written warning from community leaders, providing
-clarity around the nature of the violation and an explanation of why the
-behavior was inappropriate. A public apology may be requested.
-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series of
-actions.
-
-**Consequence**: A warning with consequences for continued behavior. No
-interaction with the people involved, including unsolicited interaction with
-those enforcing the Code of Conduct, for a specified period of time. This
-includes avoiding interactions in community spaces as well as external channels
-like social media. Violating these terms may lead to a temporary or permanent
-ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or
-private interaction with the people involved, including unsolicited interaction
-with those enforcing the Code of Conduct, is allowed during this period.
-Violating these terms may lead to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of community
-standards, including sustained inappropriate behavior, harassment of an
-individual, or aggression toward or disparagement of classes of individuals.
-
-**Consequence**: A permanent ban from any sort of public interaction within the
-community.

-**This guide was heavily inspired by the awesome [scikit-learn guide to contributing](https://github.com/scikit-learn/scikit-learn/blob/main/CONTRIBUTING.md).**
-
-## Ways to contribute
-
-There are several ways you can contribute to text-generation-inference.
-
-* Fix outstanding issues with the existing code.
-* Submit issues related to bugs or desired new features.
-* Contribute to the examples or to the documentation.
-
-> All contributions are equally valuable to the community. 🥰
-
-## Fixing outstanding issues
-
-If you notice an issue with the existing code and have a fix in mind, feel free to [start contributing](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request) and open
-a Pull Request!
-
-## Submitting a bug-related issue or feature request
-
-Do your best to follow these guidelines when submitting a bug-related issue or a feature
-request. It will make it easier for us to come back to you quickly and with good
-feedback.
-
-### Did you find a bug?
-
-The text-generation-inference library is robust and reliable thanks to users who report the problems they encounter.
-
-Before you report an issue, we would really appreciate it if you could **make sure the bug was not
-already reported** (use the search bar on GitHub under Issues). Your issue should also be related to bugs in the
-library itself, and not your code.
-
-Once you've confirmed the bug hasn't already been reported, please include the following information in your issue so
-we can quickly resolve it:
-
-* Your **OS type and version**, as well as your environment versions (versions of rust, python, and dependencies).
-* A short, self-contained, code snippet that allows us to reproduce the bug.
-* The *full* traceback if an exception is raised.
-* Attach any other additional information, like screenshots, you think may help.
-
-To get the OS and software versions automatically, you can re-run the launcher with the `--env` flag:
-
-```bash
-text-generation-launcher --env
-```
-
-This will precede the launch of the model with the information relative to your environment. We recommend pasting
-that in your issue report.
-
-### Do you want a new feature?
-
-If there is a new feature you'd like to see in text-generation-inference, please open an issue and describe:
-
-1. What is the *motivation* behind this feature? Is it related to a problem or frustration with the library? Is it
-   a feature related to something you need for a project? Is it something you worked on and think it could benefit
-   the community?
-
-   Whatever it is, we'd love to hear about it!
-
-2. Describe your requested feature in as much detail as possible. The more you can tell us about it, the better
-   we'll be able to help you.
-3. Provide a *code snippet* that demonstrates the feature's usage.
-4. If the feature is related to a paper, please include a link.
-
-If your issue is well written we're already 80% of the way there by the time you create it.
-
-We have added [templates](https://github.com/huggingface/text-generation-inference/tree/main/.github/ISSUE_TEMPLATE)
-to help you get started with your issue.
-
-## Do you want to implement a new model?
-
-New models are constantly released and if you want to implement a new model, please provide the following information:
-
-* A short description of the model and a link to the paper.
-* Link to the implementation if it is open-sourced.
-* Link to the model weights if they are available.
-
-If you are willing to contribute the model yourself, let us know so we can help you add it to text-generation-inference!
-
-## Do you want to add documentation?
-
-We're always looking for improvements to the documentation that make it more clear and accurate. Please let us know
-how the documentation can be improved such as typos and any content that is missing, unclear or inaccurate. We'll be
-happy to make the changes or help you make a contribution if you're interested!
-
-## I want to become a maintainer of the project. How do I get there?
-
-TGI is a project led and managed by Hugging Face as it powers our internal services. However, we are happy to have
-motivated individuals from other organizations join us as maintainers with the goal of making TGI the best inference
-service.
-
-If you are such an individual (or organization), please reach out to us and let's collaborate.

 For a detailed starting guide, please see the [Quick Tour](https://huggingface.co/docs/text-generation-inference/quicktour). The easiest way of getting started is using the official Docker container:
 
 ```shell
-model=HuggingFaceH4/zephyr-7b-beta
-# share a volume with the Docker container to avoid downloading weights every run
-volume=$PWD/data
+model=tiiuae/falcon-7b-instruct
+volume=$PWD/data # share a volume with the Docker container to avoid downloading weights every run
 
-docker run --gpus all --shm-size 1g -p 8080:80 -v $volume:/data \
-    ghcr.io/huggingface/text-generation-inference:3.2.3 --model-id $model
+docker run --gpus all --shm-size 1g -p 8080:80 -v $volume:/data ghcr.io/huggingface/text-generation-inference:1.1.1 --model-id $model
 ```
 
 And then you can make requests like
 
 ```bash
-curl 127.0.0.1:8080/generate_stream \
+curl 127.0.0.1:8080/generate \
     -X POST \
     -d '{"inputs":"What is Deep Learning?","parameters":{"max_new_tokens":20}}' \
     -H 'Content-Type: application/json'

-### Local install (Nix)
+### CUDA Kernels
 
-Another option is to install `text-generation-inference` locally using [Nix](https://nixos.org). Currently,
-we only support Nix on x86_64 Linux with CUDA GPUs. When using Nix, all dependencies can
-be pulled from a binary cache, removing the need to build them locally.
+The custom CUDA kernels are only tested on NVIDIA A100s. If you have any installation or runtime issues, you can remove
+the kernels by using the `DISABLE_CUSTOM_KERNELS=True` environment variable.
 
-First follow the instructions to [install Cachix and enable the TGI cache](https://app.cachix.org/cache/text-generation-inference).
-Setting up the cache is important, otherwise Nix will build many of the dependencies
-locally, which can take hours.
-
-After that you can run TGI with `nix run`:
-
-```shell
-cd text-generation-inference
-nix run --extra-experimental-features nix-command --extra-experimental-features flakes . -- --model-id meta-llama/Llama-3.1-8B-Instruct
-```
-
-**Note:** when you are using Nix on a non-NixOS system, you have to [make some symlinks](https://danieldk.eu/Nix-CUDA-on-non-NixOS-systems#make-runopengl-driverlib-and-symlink-the-driver-library)
-to make the CUDA driver libraries visible to Nix packages.
-
-For TGI development, you can use the `impure` dev shell:
-
-```shell
-nix develop .#impure
-
-# Only needed the first time the devshell is started or after updating the protobuf.
-(
-cd server
-mkdir text_generation_server/pb || true

-# Text-generation-inference - Gaudi backend
-
-## Description
-
-This is the TGI backend for Intel Gaudi. This backend is composed of the tgi server optimized for Gaudi hardware.
-
-## Build your own image
-
-The simplest way to build TGI with the Gaudi backend is to use the provided `Makefile`:
-
-Option 1: From the project root directory:
-```bash
-make -C backends/gaudi image
-```
-
-Option 2: From the Gaudi backend directory:
-```bash
-cd backends/gaudi
-make image
-```
-
-You can now run the server with the following command:
-
-Option 1: Sharded:
-```bash
-model=meta-llama/Llama-3.1-8B-Instruct
-hf_token=$(cat ${HOME}/.cache/huggingface/token)
-volume=${HOME}/.cache/huggingface
-
-docker run --runtime=habana --ipc=host --cap-add=sys_nice \
-  -p 8080:80 -v $volume:/data \
-  -e LOG_LEVEL=debug -e HF_TOKEN=$hf_token \
-  tgi-gaudi --model-id $model \
-  --sharded true --num-shard 8 \
-  --max-input-tokens 512 --max-total-tokens 1024 --max-batch-size 8 --max-batch-prefill-tokens 2048
-```
-
-Option 2: Non-sharded:
-```bash
-model=meta-llama/Llama-3.1-8B-Instruct
-hf_token=$(cat ${HOME}/.cache/huggingface/token)
-volume=${HOME}/.cache/huggingface
-
-docker run --runtime=habana --ipc=host --cap-add=sys_nice \
-  -p 8080:80 -v $volume:/data \
-  -e LOG_LEVEL=debug -e HF_TOKEN=$hf_token \
-  tgi-gaudi --model-id $model \
-  --max-input-tokens 512 --max-total-tokens 1024 --max-batch-size 4 --max-batch-prefill-tokens 2048
-```
-
-## Contributing
-
-### Local Development
-
-This is useful if you want to run the server locally for better debugging.
-```bash
-make -C backends/gaudi run-local-dev-container
-```
-
-Then run the following command inside the container to install tgi for gaudi:
-```bash
-make -C backends/gaudi local-dev-install
-```
-
-Add rust to path:
-```bash
-. "$HOME/.cargo/env"
-```
-
-Option 1: Run the server (sharded model):
-```bash
-LOG_LEVEL=debug text-generation-launcher \
-    --model-id meta-llama/Llama-3.1-8B-Instruct \
-    --sharded true \
-    --num-shard 8 \
-    --max-input-tokens 512 \
-    --max-total-tokens 1024 \
-    --max-batch-size 8 \
-    --max-batch-prefill-tokens 2048
-```
-
-Option 2: Run the server (non-sharded model):
-```bash
-LOG_LEVEL=debug text-generation-launcher \
-    --model-id meta-llama/Llama-3.1-8B-Instruct \
-    --max-input-tokens 512 \
-    --max-total-tokens 1024 \
-    --max-batch-size 4 \
-    --max-batch-prefill-tokens 2048
-```
-
-You can then test the server with the following curl command from another terminal (can be outside the container):
-```bash
-curl 127.0.0.1:8080/generate \
-     -X POST \
-     -d '{"inputs":"What is Deep Learning?","parameters":{"max_new_tokens":20}}' \
-     -H 'Content-Type: application/json'
-```
-
-### Integration tests
-
-To run the integration tests, you need to first build the image:
-```bash
-make -C backends/gaudi image
-```
-
-Then run the following command to run the integration tests:
-```bash
-make -C backends/gaudi run-integration-tests
-```
-
-To capture the expected outputs for the integration tests, you can run the following command:
-```bash
-make -C backends/gaudi capture-expected-outputs-for-integration-tests
-```
-
-#### How the integration tests works
-The integration tests works as follows:
-
-1. Start a tgi server in a container, similar to the command:
-```bash
-docker run --runtime=habana --ipc=host --cap-add=sys_nice \
-  -p 8080:80 -v $volume:/data \
-  -e LOG_LEVEL=debug -e HF_TOKEN=$hf_token \
-  tgi-gaudi --model-id $model \
-  --max-input-tokens 512 --max-total-tokens 1024 --max-batch-size 4 --max-batch-prefill-tokens 2048
-```
-
-2. Do a /generate request to the server, similar to the command:
-```bash
-curl 127.0.0.1:8080/generate \
-     -X POST \
-     -d '{"inputs":"What is Deep Learning?","parameters":{"max_new_tokens":20}}' \
-     -H 'Content-Type: application/json'
-```
-
-3. Check the output of the server against the expected output:
-```python
-assert curl_output == expected_output
-```
-
-This is the repeated for a set of models and configurations.
