Bentoml releases LLM-Optimizer: an open source AI tool for benchmarking and optimizing LLM inference

Bentoml has recently released llm-optimizerThis is an open source framework designed to simplify benchmarking and performance tuning for self-hosted large language model (LLMS). This tool solves a common challenge in LLM deployment: finding the best configuration for latency, throughput, and cost without relying on manual repeated trials.

Why is it difficult to adjust LLM performance?

Adjusting LLM reasoning is the balanced behavior of many moving parts – batch size, frame selection (VLLM, SGLANG, etc.), tensor parallelism, sequence length, and how the hardware is used. Each of these factors can change performance in different ways, which makes finding the right combination of speed, efficiency and cost far from being a direct combination. Most teams still rely on repeated trial and error tests, a process that is slow, inconsistent and often inconclusive. For self-hosted deployments, it’s expensive to get it wrong: poorly tuned configurations can quickly translate into higher latency and wasted GPU resources.

What is the difference between llm oftimizer?

llm-optimizer A structured method for exploring LLM performance landscape is provided. It eliminates duplicate guesses by enabling system benchmarking and automatic search in possible configurations.

Core functions include:

• Run standardized tests across inference frameworks such as VLLM and SGLANG.
• Apply constraint-driven adjustments, for example, only horizontal configurations are performed only when 200ms are below 200ms when surfaced.
• Automate parameter scanning to identify the best settings.
• Visualize the tradeoffs with latency, throughput and GPU utilization.

The framework is open source and is available on GitHub.

How do developers explore results without running benchmarks locally?

In addition to the optimizer, Bentoml released LLM Performance Explorer, a browser-based interface powered by LLM-Optimizer. It provides expected benchmark data for popular open source models and allows users to:

• Compare frameworks and configurations side by side.
• Filtered by latency, throughput, or resource thresholds.
• Interactive browsing trade-offs are made without hardware.

How does LLM reflector affect LLM deployment practices?

As the use of LLMS increases, the maximum gain from deployment comes down to the degree of tuning of the inference parameters. LLM expellers reduce the complexity of this process, allowing smaller teams to access optimization technologies that once required large-scale infrastructure and deep expertise.

By providing standardized benchmarks and reproducible results, this framework adds much-needed transparency to the LLM space. It makes comparisons across models and frameworks more consistent, thereby narrowing the long-term gap in the community.

Ultimately, BENTOML’s LLM-Optimizer will constrain-driven, benchmark-centric approaches to self-hosted LLM optimization, replacing temporary trials and errors with a systematic and repeatable workflow.
