LLMFly AI

LLMFly AI is an OpenAI-compatible API gateway: one key and one endpoint for GPT, Claude, Gemini, Grok and other leading models, with a centralized model catalog, price comparison across providers, key management, usage tracking and docs for integrating into apps, agents, scripts and backends. Free credits on signup plus a 10% referral reward program. Interface ships in English, simplified/traditional Chinese, Japanese and Korean.

This is the standard API-aggregator play — the differentiators to evaluate are uptime, rate limits, billing transparency and how quickly new models land after release, not the model list (they all list the same models).

Who it's for: developers who want multi-model access without multiple vendor accounts, and teams routing different tasks to different models through one integration. The aggregator test is boring but essential: check latency and error rates on your real traffic for a week before moving production volume, and read the terms on data handling — routing your prompts through a third party is a trust decision, not just a price decision.
