The best tools for Low-cost LLM API

For low-cost LLM API needs, your best pick is DeepSeek. It offers extremely competitive pricing for quality open-weight models that can be self-hosted, making it ideal for cost-sensitive API builders and teams looking to manage their expenses while still achieving strong coding and reasoning performance. If you need an affordable option focused strictly on cost-effectiveness, DeepSeek stands out.

However, if you're already integrated into the Google ecosystem and seek a multimodal AI experience, Google Gemini might be the better fit. It provides very cheap models for high-volume API use and excels at handling various media types, which can be crucial for applications that require more than just text. Ultimately, it boils down to whether you prioritize self-hosting capabilities and straightforward API pricing (DeepSeek) or multimodal functionalities and app integration (Google Gemini).
