Drop-in replacement for OpenAI SDK saved our backend team hours.
Routing multiple LLMs through one key is super clean.
Had a brief rate-limit glitch during peak hours.

AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Call GPT, Claude, Gemini and Grok models by changing only your base URL, API key and model ID, keeping your existing OpenAI or Anthropic SDK code largely intact.
Each catalog entry publishes its own input, output and cache pricing, with side-by-side comparisons against official reference rates.
Issue separate keys per application and environment, then inspect usage records to support cost reviews, debugging and rate-limit investigations.
Copy the provided integration guide straight into Claude Code, Codex or Cursor, or call the endpoint from backend services and automation scripts.
Direct assistance covering initial setup, everyday requests, failures, rate limits and client errors.
LLMFly AI positions itself as a single API layer in front of several frontier model families. Instead of maintaining a separate integration, billing relationship and SDK for every provider, developers point their server-side OpenAI client at the LLMFly AI base URL, swap in an API key and a model ID, and keep using the tooling they already have. The site emphasises drop-in compatibility with the OpenAI SDK as well as Anthropic SDK and common coding agents such as Claude Code, Codex and Cursor.
The platform is oriented around cost visibility and day-to-day operational support. Each model in the catalog lists its own input, output and, where available, cached-token rates, and pages let you compare official reference prices against current LLMFly AI rates. Per-application keys, usage records and rate inspection are meant to support development workflows, cost reviews and troubleshooting. The company also advertises one-to-one technical assistance covering setup, failures, rate limits and client errors.
The catalog is described as changeable — availability shifts over time — so the recommended workflow is to check the model list for current model IDs before sending a request, starting with a short non-streaming call. New accounts are offered free credits and a referral reward. Note that LLMFly AI is an independent third-party gateway and is not affiliated with the model vendors whose names appear in its catalog.
Keep your OpenAI SDK client and change the base URL, key and model ID to route traffic across model families.
Compare model rates in one place and review usage records to understand what each feature actually costs.
Send short non-streaming test requests against different model IDs to find the best fit before committing.
Point Claude Code, Codex, Cursor or a scheduled script at the same endpoint for consistent access.
