Real outputs generated by the API
Frontier reasoning
“Multi-step math, formal proofs, scientific reasoning at SOTA quality”
Agentic coding

Why GPT-5.5 Pro
50% off OpenAI Pro pricing
$5 input / $30 output per million tokens vs $10 / $60 official. Same reasoning depth, same model variants.
Configurable reasoning effort
Set reasoning_effort to low, medium, or high to trade latency for depth — same parameter as official OpenAI Pro.
400K context, 128K max output
Full GPT-5.5 Pro spec: 400,000-token input, 128,000-token output. Handles entire codebases and large documents.

Which credits get consumed?
One API key works for both. Routing is decided by the model you call, not by the key.
Claude Opus 4.7, Sonnet 4.6, GPT-5.5 drain Coding Credits first (FIFO), then spill to General Credits if Coding Credits run out.
Image, video, audio, 3D, and all other LLMs drain General Credits only. Coding Credits stay reserved for coding workloads.
