To make **LLM-driven inference** fast while maintaining its dynamic capabilities, there are a few practices or approaches to avoid, as they could lead to performance bottlenecks or inefficiencies. Here's what *not* to do:
|
||
|
||
---
|
||
|
||
### **1. Avoid Using Overly Large Models for Every Query**
|
||
While larger LLMs like GPT-4 provide high accuracy and nuanced responses, they may slow down real-time processing due to their computational complexity. Instead:
|
||
- Use distilled or smaller models (e.g., GPT-3.5 Turbo or fine-tuned versions) for faster inference without compromising much on quality.
|
||
|
||
---
|
||
|
||
### **2. Avoid Excessive Entity Preprocessing**
|
||
Don’t rely on overly complicated preprocessing steps (like advanced NER models or regex-heavy pipelines) to extract entities from the query before invoking the LLM. This could add latency. Instead:
|
||
- Design efficient prompts that allow the LLM to extract entities and generate responses simultaneously.
|
||
|
||
---
|
||
|
||
### **3. Avoid Asking the LLM Multiple Separate Questions**
|
||
Running the LLM for multiple subtasks—for example, entity extraction first and response generation second—can significantly slow down the pipeline. Instead:
|
||
- Create prompts that combine tasks into one pass, e.g., *"Identify the city name and generate a weather response for this query: 'What's the weather in London?'"*.
|
||
|
||
---
|
||
|
||
### **4. Don’t Overload the LLM with Context History**
|
||
Excessively lengthy conversation history or irrelevant context in your prompts can slow down inference times. Instead:
|
||
- Provide only the relevant context for each query, trimming unnecessary parts of the conversation.
|
||
|
||
---
|
||
|
||
### **5. Avoid Real-Time Dependence on External APIs**
|
||
Using external APIs to fetch supplementary data (e.g., weather details or location info) during every query can introduce latency. Instead:
|
||
- Pre-fetch API data asynchronously and use the LLM to integrate it dynamically into responses.
|
||
|
||
---
|
||
|
||
### **6. Avoid Running LLM on Underpowered Hardware**
|
||
Running inference on CPUs or low-spec GPUs will result in slower response times. Instead:
|
||
- Deploy the LLM on optimized infrastructure (e.g., high-performance GPUs like NVIDIA A100 or cloud platforms like Azure AI) to reduce latency.
|
||
|
||
---
|
||
|
||
### **7. Skip Lengthy Generative Prompts**
|
||
Avoid prompts that encourage the LLM to produce overly detailed or verbose responses, as these take longer to process. Instead:
|
||
- Use concise prompts that focus on generating actionable or succinct answers.
|
||
|
||
---
|
||
|
||
### **8. Don’t Ignore Optimization Techniques**
|
||
Failing to optimize your LLM setup can drastically impact performance. For example:
|
||
- Avoid skipping techniques like model quantization (reducing numerical precision to speed up inference) or distillation (training smaller models).
|
||
|
||
---
|
||
|
||
### **9. Don’t Neglect Response Caching**
|
||
While you may not want a full caching system to avoid sunk costs, dismissing lightweight caching entirely can impact speed. Instead:
|
||
- Use temporary session-based caching for very frequent queries, without committing to a full-fledged cache infrastructure.
|
||
|
||
---
|
||
|
||
### **10. Avoid One-Size-Fits-All Solutions**
|
||
Applying the same LLM inference method to all queries—whether simple or complex—will waste processing resources. Instead:
|
||
- Route basic queries to faster, specialized models and use the LLM for nuanced or multi-step queries only.
|
||
|
||
---
|
||
|
||
### Summary: Focus on Efficient Design
|
||
By avoiding these pitfalls, you can ensure that LLM-driven inference remains fast and responsive:
|
||
- Optimize prompts.
|
||
- Use smaller models for simpler queries.
|
||
- Run the LLM on high-performance hardware.
|
||
- Trim unnecessary preprocessing or contextual steps.
