Description
This model as intended to be used as an accelerator for llama 13B (chat).
Undlerlying implementation of Paged Attention KV-Cached and speculator can be found in https://github.com/foundation-model-stack/fms-extras
Production implementation using fms-extras implementation can be found in https://github.com/tdoublep/text-generation-inference/tree/speculative-decoding
To try this out running in a production-like environment, please use the pre-built docker image:
docker pull docker-eu-public.artifactory.swg-devops.com/res-zrl-snap-docker-local/tgis-os:spec.7
docker run -d --rm --gpus all \
--name my-tgis-server \
-p 8033:8033 \
-v /path/to/all/models:/models \
-e MODEL_NAME=/models/model_weights/llama/13B-F \
-e SPECULATOR_PATH=/models/speculator_weights/llama/13B-F \
-e FLASH_ATTENTION=true \
-e PAGED_ATTENTION=true \
-e DTYPE_STR=float16 \
docker-eu-public.artifactory.swg-devops.com/res-zrl-snap-docker-local/tgis-os:spec.7
# check logs and wait for "gRPC server started on port 8033" and "HTTP server started on port 3000"
docker logs my-tgis-server -f
# get the client sample (Note: The first prompt will take longer as there is a warmup time)
conda create -n tgis-env python=3.11
conda activate tgis-env
git clone --branch speculative-decoding --single-branch https://github.com/tdoublep/text-generation-inference.git
