Hi HN,
I'm building Nexus Gateway, an AI gateway that helps developers reduce LLM API costs.
Problem:
Many applications send repeated or semantically similar prompts to LLMs, which leads to unnecessary API calls and higher costs.
Solution:
Nexus Gateway uses semantic caching to detect similar prompts and serve cached responses instead of calling the LLM again.
Features:
• Semantic caching to reduce repeated API calls
• Multi-model support (OpenAI, Gemini, Llama, Anthropic)
• BYOK support
• PII protection and sovereign AI layer (in progress)
Goal:
Reduce LLM costs by 40–70% while improving latency.
I’d really appreciate feedback from the community.
