What is Infron?
Infron is a US-based AI gateway and inference platform. One OpenAI-compatible API reaches 400+ models from 100+ providers, including DeepSeek, Qwen, Claude, Gemini and GPT through what Infron calls official partner routes, plus media and search models. Teams set provider preferences and fallbacks, see usage and billing in one place, and can bring their own provider keys at no fee. Lawrence Xu is CEO and co-founder Andrew Zheng is CTO.
Pricing passes provider rates through with no markup. Pay-as-you-go users pay a 5% plus $0.35 fee when adding credits, and enterprise plans drop that to 3% with tiered discounts of up to 30% off by monthly usage. Infron runs open models like Qwen, DeepSeek, Kimi and GLM on Alibaba Cloud capacity across five regions, lets customers pin requests to a region for latency or data residency, and offers dedicated throughput with a 99.9% uptime SLA. It keeps no prompt or response content by default, and its SOC 2 Type II audit is in progress. Customer Agnes AI reports 60% lower AI costs while reaching 3M users.
Infron pros, cons and use cases
Upsides
- Closed and open models on one key and one bill, with automatic failover across providers.
- No markup on model prices, plus enterprise discounts of up to 30%.
- Region pinning across Asia, Europe and the US for latency and data residency.
Core use cases
- Multi-model products that want one API and fallback across providers.
- Teams in Asia that need regional open-model capacity with an SLA.
Downsides
- Adds a hop and a 3% to 5% top-up fee on top of provider rates.
- Young company with SOC 2 still in progress and little independent benchmarking.
