## Choose when

### Choose ChatAbstractions if…

- ChatAbstractions is primarily Python; awesome-free-llm-apis is JavaScript.
- License: ChatAbstractions is MIT, awesome-free-llm-apis is CC0-1.0.
- Requirements: Min 2 GB RAM.
- Tags unique to ChatAbstractions: chat-models, dynamic-failover, langchain, load-balancing.
- - When you need dynamic model selection in your application to switch between different LLMs at runtime based on performance or outages.

### Choose awesome-free-llm-apis if…

- awesome-free-llm-apis is primarily JavaScript; ChatAbstractions is Python.
- License: awesome-free-llm-apis is CC0-1.0, ChatAbstractions is MIT.
- Pricing: The repository lists APIs with permanent free tiers, detailing rate and token limits for those interested in using free Large Language Model services..
- Requirements: Before integration, ensure that the specific requirements for API access are met to utilize these models without restriction.; Users should review the rate and token limits associated with each API provider to determine suitability based on their project's needs..
- Tags unique to awesome-free-llm-apis: ai-agents, anthropic, gemini, llm.
- When you need text inference with specialized capabilities like roleplay and storytelling, the Aion Labs API offers a dedicated free tier specifically designed for these purposes.

## When NOT to use ChatAbstractions

- - This tool is not recommended if you are looking for static solutions where the chat model or load balancing policies do not change at runtime.
- - If you require integration with a specific set of models that aren't compatible with LangChain's `BaseChatModel`, this might not be suitable.
- - When your application has minimal risk of LLM provider outages and does not benefit from dynamic failover features.

## When NOT to use awesome-free-llm-apis

- Avoid using Aion Labs if your project involves heavy commercial activity, given its limited rate and token limits.
- Do not use Cohere for projects that will scale beyond 1,000 API calls per month or require credit card details for access to higher-tier plans.
- Google Gemini's free tier is inaccessible in the EU/UK/Switzerland regions and requires consent to let Google improve their products through your usage.
- Mistral AI should be avoided if you need strict confidentiality, as they use prompts from users' interactions to refine and train additional model iterations.
