Choose Inception Mercury if
Developers building latency-sensitive agents, voice bots or coding tools who want a fast, cheap text model behind an OpenAI-compatible API.
- Very high output speed suits real-time and agent loops
- Low list price of $0.20 input and $0.70 output per million tokens
- 100 million free tokens with no card to start
Look elsewhere if: Teams that need multimodal models, open weights or the widest ecosystem of hosted tools (Gemini, DeepSeek, Claude).
Choose RunInfra if
Developers who use coding agents heavily and want open models at a flat, predictable monthly price.
- Predictable monthly cost from $10 for agent-heavy coding
- Drop-in for tools that already speak the OpenAI or Anthropic API
- Very low per-token prices on small and fast open models
Look elsewhere if: Teams that need the strongest closed models for complex coding work (Claude, ChatGPT Codex).
