# Preto.ai ## What is Preto.ai? Preto.ai is an LLM cost optimization platform that helps AI product teams reduce OpenAI, Anthropic, NVIDIA, ElevenLabs, and Deepgram API costs by 40–60%. It works as a transparent proxy — one line of code change — and generates ranked savings recommendations with projected dollar estimates per finding. ## How it works Change your API client's base_url to proxy.preto.ai. Preto logs every LLM request with cost, model, and latency data, then runs AI analysis rules to surface the highest-impact optimizations: model downgrade opportunities, cacheable duplicates, cheaper embedding alternatives, and more. ## Key features - Real-time cost tracking by feature, user, and model - AI-powered savings recommendations with dollar estimates per finding - Hard budget enforcement — block requests at the proxy level when spend hits threshold - Works with OpenAI, Anthropic, NVIDIA NIM, ElevenLabs, Deepgram - One-line integration (change base_url only, no SDK required) - Savings dashboard tracking money recovered, not just money spent - Free to start ## Pricing - Free: $0/month - Pro: $99/month - Business: $399/month - Scale: $999/month (contact sales) ## Who built it? Preto.ai was built by Gaurav Dagde, a software engineer with 11 years of engineering leadership experience. He built Preto after repeatedly seeing AI product teams waste 40–60% of their LLM budget on model choices they never revisited. ## Main pages - https://preto.ai/ — Main landing page - https://preto.ai/alternatives/ — Comparison hub: Preto.ai vs Helicone, Langfuse, LangSmith, Datadog - https://preto.ai/helicone-alternative/ — Preto.ai vs Helicone detailed comparison - https://preto.ai/langfuse-alternative/ — Preto.ai vs Langfuse detailed comparison - https://preto.ai/langsmith-alternative/ — Preto.ai vs LangSmith detailed comparison - https://preto.ai/datadog-llm-alternative/ — Preto.ai vs Datadog LLM monitoring comparison - https://preto.ai/tools/llm-cost-calculator/ — Free LLM cost calculator (OpenAI, Anthropic, Google) - https://preto.ai/tools/llm-cost-cheat-sheet/ — LLM API pricing cheat sheet for 2026 - https://preto.ai/blog/ — Engineering blog: LLM infrastructure, cost optimization guides - https://preto.ai/about/ — About the founder ## Key differentiators vs competitors - vs Helicone: Helicone tracks costs. Preto tells you what to do about them — ranked recommendations with dollar estimates. - vs Langfuse: Langfuse focuses on traces, evals, quality. Preto focuses purely on cost reduction, with zero SDK instrumentation. - vs LangSmith: LangSmith traces LangChain pipelines. Preto is model-agnostic, proxy-based, and cost-focused. - vs Datadog: Datadog is general infrastructure monitoring. Preto is purpose-built for LLM cost intelligence. - vs OpenRouter: OpenRouter routes requests. Preto optimizes spend — you keep your own API keys. ## Contact Email: gaurav@preto.ai GitHub: https://github.com/pretoai Twitter: https://twitter.com/pretoai
