## Choose when

### Choose LLM-Finetuning-Toolkit if…

- LLM-Finetuning-Toolkit is primarily Python; GPTRouter is TypeScript.
- License: LLM-Finetuning-Toolkit is Apache-2.0, GPTRouter is MIT.
- Tags unique to LLM-Finetuning-Toolkit: ablation-study, classification, falcon, fine-tuning.
- When working specifically with Falcon, Flan-T5, LLama2, Mistral-7B or Zephyr models due to inbuilt support

### Choose GPTRouter if…

- GPTRouter is primarily TypeScript; LLM-Finetuning-Toolkit is Python.
- License: GPTRouter is MIT, LLM-Finetuning-Toolkit is Apache-2.0.
- Pricing: GPTRouter is open-source under the MIT License. However, costs might arise from using associated models like OpenAI or Anthropic..
- Requirements: Min 2 GB RAM.
- Tags unique to GPTRouter: anthropic, azure-openai, cohere, google-gemini.
- Also covers Inference & Serving.
- When your project requires seamless integration of different language models such as OpenAI, Anthropic, and Azure and demands reliability and fast response times.

## When NOT to use LLM-Finetuning-Toolkit

- If prioritizing proprietary LLMs not listed as supported within the toolkit
- When working with languages other than Python, since toolkit is exclusively for Python environments

## When NOT to use GPTRouter

- Avoid using GPTRouter if your project strictly uses Python without the flexibility to adopt TypeScript, as it may hinder seamless integration.
- If your application exclusively focuses on a single LLM or image model provider lacking the need for managing multiple providers, consider alternatives more focused in scope and potentially lighter.
