<h3>SemanticGuard: AI Gateway with Self-Validating Cache</h3>SemanticGuard is an advanced AI gateway designed to significantly reduce your Large Language Model (LLM) API costs, offering savings of 40-70%. It achieves this through intelligent semantic caching, ensuring that repeated or similar queries are served from a cache, thereby minimizing expensive calls to external LLM providers.Key Features:<ul><li>Cost Reduction: Cuts LLM API costs by 40-70% through sophisticated caching mechanisms.</li><li>Self-Validating Cache: Utilizes your own AI to validate every cached response for correctness, preventing the silent serving of inaccurate information.</li><li>Continuous Learning: Employs LLM-based skeleton extraction to identify variable prompt slots, enabling more effective caching.</li><li>Multi-Layer Cache: Supports exact, template, substituted, and semantic caching strategies for maximum efficiency.</li><li>One-Line Integration: Seamlessly integrates into your existing workflow with a single line of code using the provided SDK (e.g., fetch: withSemanticGuard()).</li><li>Shadow Mode: Allows you to measure potential savings and analyze cost visibility without serving cached responses, ensuring a risk-free trial.</li><li>Real-time Analytics: Provides a dashboard for cost analytics, savings tracking, and cache performance monitoring.</li><li>Multi-Provider Support: Works with a wide range of LLM providers including OpenAI, Anthropic, Google Vertex AI, Azure, AWS Bedrock, and Mistral.</li><li>Fail-Open Design: Ensures zero downtime by routing requests directly to your provider if the cache is unavailable.</li><li>AI Agent Compatibility: Exposes an OpenAI-compatible API and includes an MCP server for seamless integration with AI agents and dev tools like LangChain, CrewAI, AutoGen, Claude, and Cursor.</li></ul>SemanticGuard is built for production environments, offering a robust solution for managing LLM expenses without compromising on response quality or integration ease. Deployable on platforms like Vercel, it ensures your data remains within your infrastructure.Pricing Tiers:<ul><li>Free: Includes 10K requests/month, Shadow Mode, exact match cache, cost analytics, and request tracing.</li><li>Pro: Offers 50K included requests, full semantic caching, advanced pattern matching, and enhanced analytics.</li><li>Enterprise: Priced at 15% of documented savings with a $500/month minimum, providing unlimited requests and custom solutions.</li></ul>
