We were spending too much on LLM API calls — and realized most prompts carry redundant tokens that inflate costs without adding value. So we built PithToken: an API proxy that sits between your app and any OpenAI-compatible provider. It optimizes your prompts automatically before forwarding them. What you get: • 48% average token reduction (benchmarked on 100K real conversations from LMSYS-Chat-1M) • 97%+ semantic fidelity — same meaning, fewer tokens • 3-layer prompt injection detection (regex + heuristic + ML) • 19 language support • Semantic caching for repeated/similar prompts How it works: 1. Point your base_url to api.pithtoken.ai 2. Your prompts get optimized automatically 3. You get the same quality response at ~half the cost No vendor lock-in. Works with OpenAI, Anthropic, and any OpenAI-compatible API. We built this for developers who want to ship AI products without burning through their API budget.
