Introduction

ts_server is a web server proposing a REST API to large language models. They can be used for example for text completion, question answering, classification, chat, translation, image generation, ...

It has the following characteristics:

All is included in a single binary. Very few external dependencies (Python is not needed) so installation is easy.
Supports many Transformer variants (GPT-J, GPT-NeoX, GPT-Neo, OPT, Fairseq GPT, M2M100, CodeGen, GPT2, T5, RWKV, LLAMA, Falcon, MPT, Llama 2, Mistral, Mixtral, Whisper) and Stable Diffusion.
Integrated REST JSON API for text completion, translation, image generation and audio transcription. It is used by textsynth.com.
Integrated HTML GUI for testing.
Very high performance for small and large batches on CPU and GPU. Support of dynamic batching to handle a large number of simultaneous requests.
Efficient custom 8, 4 and 3 bit quantization. Our quantized models are thoroughly evaluated on several standard tasks to ensure good performance.
Larger models work optimally on lower cost GPUs (e.g. RTX 3090, RTX A6000) thanks to efficient quantization.
Support of speculative sampling for even faster inference.
Support of grammar based sampling to constraint the model output according to a BNF grammar or a JSON schema.
Uses the LibNC library for simple tensor manipulation using the C language.
Simple command line tools (ts_test, ts_sd, ts_chat are provided to test the various models).

The free version is released as binary code for non-commercial use only. It has some limitations compared to the commercial version. Please contact for the exact terms.

Benchmarks

Text generation

100 tokens are generated with a batch size of 1 and 50 input tokens:

Model⁽³⁾	Epyc 7313 (6) (tokens/s)	RTX A6000 (tokens/s)	RTX 4090 (tokens/s)
gptj_6B_q4	21.5	132	164

gptneox_20B_q4	8.1	45.5	59
llama2_70B_q4	2.5	15.2	-

8 simultaneous requests generating 100 tokens with 50 input tokens (equivalent to a batch size of 8):

Model⁽³⁾	RTX A6000 (tokens/s)
llama2_7B_q4	783
llama2_13B_q4	492
llama2_70B_q4	118

Text to image

A single 512x512 image is generated using 50 time steps.

stable diffusion 2.1	1.67	1.19

Available Models

We provide here model files that can be used with the TextSynth Server. Each model was evaluated with the lm-evaluation-harness with the TextSynth server on a RTX A6000 GPU.

Notes:

Some models have restrictive licenses. In particular, OPT, Vicuna and NLLB200 cannot be used commercially. BLOOM, Stable Diffusion and Llama 2 can be used commercially but have use limitations.
For the larger models we don't provide the unquantized version when it is too large for consumer GPUs or when the quantized version gives the same performance as the unquantized version.
The q8 suffix indicates that the model was 8 bit quantized. The q4 suffix indicates that the model was 4 bit quantized. The q3 suffix indicates that the model was 3 bit quantized. Unquantized models use either float16 or bfloat16 parameters.
File size on disk (1 GB = 10⁹ bytes). The amount of CPU or GPU RAM needed to run the model is close to this value.
lambada perplexity (ppl) are comparable only for models using the same tokenizer. So the lambada accuracy (acc) should be used when comparing all models.
The speed is measured on an AMD Epyc 7313 CPU using 16 threads (ts_test -T 16)
