LLM Comparison Through TGI Benchmark Using SaladCloud

Salad Technologies

In the field of Artificial Intelligence (AI), Text Generation Inference (TGI) has become a vital toolkit for deploying and serving Large Language Models (LLMs). TGI enables efficient and scalable text generation with popular open-source LLMs, including Llama, Falcon, StarCoder, BLOOM, GPT-NeoX, and Mistral. This SaladCloud benchmark dives deep into this technology, with a LLM comparison focused on the performance of popular language models.

TGI and Large Language Models

TGI is essential for leveraging the capabilities of Large Language Models, which are key to many AI applications today. These models, known for generating text that closely resembles human writing, are crucial for applications ranging from automated customer service to creative content generation.
You can easily deploy TGI on Salad using the following instructions:

The TGI benchmark provides us with the following metrics for each batch we provided:

  • Prefill Latency
  • Prefill Throughput
  • Decode (token) Latency
  • Decode (total) Latency
  • Decode throughput


bigcode/santacoder is part of the SantaCoder series, featuring 1.1 billion parameters and trained on subsets of Python, Java, and JavaScript from The Stack (v1.1). This model, known for its Multi Query Attention and a 2048-token context window, utilizes advanced training techniques like near-deduplication and comment-to-code ratio filtering. The SantaCoder series also includes variations in architecture and objectives, providing diverse capabilities in code generation and analysis. This is the smallest model in our benchmark.

Key observations

  1. Scalability with Batch Size: As the batch size increased, we observed a general trend of increased latency. However, the model scaled efficiently up to a certain point, beyond which the increase in latency became more pronounced.
  2. Optimal Performance: The model showed optimal performance in terms of both latency and throughput at mid-range batch sizes. Particularly, batch sizes of 16 and 32 offered a good balance between speed and efficiency. For our price per token calculation, we will take a batch of 32.
  3. Throughput Efficiency: In terms of tokens per second, the model demonstrated impressive throughput, particularly at higher batch sizes. This indicates the model’s capability to handle larger workloads effectively.

Cost-effectiveness on Salad Cloud: bigcode/santacoder

A key part of our analysis focused on the cost-effectiveness of running TGI models on SaladCloud. For a batch size of 32, with a compute cost of $0.35 per hour, we calculated the cost per million tokens based on throughput :

  • Average Throughput: 3191 tokens per second

The cost per token, considering the throughput and compute price, is approximately $0.03047 or about 3.047 cents per million tokens for output and $0.07572 per million input tokens.


Falcon-7B is a decoder-only model with 7 billion parameters, built by TII and trained on an extensive 1,500B tokens dataset from RefinedWeb, enhanced with curated corpora. It is available under the Apache 2.0 license, making it a significant model for large-scale text generation tasks.

Key findings

  • Latency Trends: As the batch size increased, there was a noticeable increase in average latency after batch 16.
  • Throughput Efficiency: The throughput in tokens per second showed significant improvement as the batch size increased, indicating the model’s capability to handle larger workloads efficiently.
  • Optimal Performance: The model demonstrated a balance between speed and efficiency at mid-range batch sizes, with batch size 16, 32 and 64 showing notable throughput efficiency.

Cost-effectiveness on SaladCloud: Tiiuae/Falcon-7b

For the tiiuae/falcon-7b model on SaladCloud with a batch size of 32 and a compute cost of $0.35 per hour, the calculated cost per million tokens with a throughput of 744 tokens per second is approximately $0.13095, or about 13.095 cents per million output tokens and $0.28345 per million input tokens.

Average decode total latency for batch size 32 is 300.82 milliseconds. While this latency might be slightly higher compared to smaller models, it still falls within a reasonable range for many applications, especially considering the model’s large size of 7 billion parameters.

The cost-effectiveness, combined with the model’s capabilities, makes it a viable option for extensive text generation tasks on SaladCloud.

Code Llama

Code Llama is a collection of generative text models, with the base model boasting 7 billion parameters. It’s part of a series ranging up to 34 billion parameters, specifically tailored for code-related tasks. This benchmark focuses on the base 7B version in Hugging Face Transformers format, designed to handle a wide range of coding applications.

  • Latency Trends: A gradual increase in latency was observed as the batch size increased, with the highest latency noted at batch size 128.
  • Throughput Efficiency: The model displayed improved throughput efficiency with larger batch sizes, indicative of its ability to handle increasing workloads.
  • Balance in Performance: Optimal performance, in terms of speed and efficiency, was noted at mid-range batch sizes.

The cost for processing one million tokens using the Code Llama model on SaladCloud, with a batch size of 32 and a compute cost of $0.35 per hour, is approximately $0.11826 per million output tokens and $0.28679 per million input tokens. This figure highlights the economic feasibility of utilizing SaladCloud for large-scale text generation tasks with sophisticated models like Code Llama.
