By use case

​
Model ID naming conventions

  • Official original ID: gpt-5.5, claude-opus-4-8, gemini-3.1-pro-preview — consistent with each vendor.
  • Reasoning-effort suffix: -high / -medium / -low controls the reasoning budget of o3, gpt-5.x, Gemini Thinking, etc.
  • Thinking toggle: claude-3-7-sonnet-20250219-thinking, gemini-2.5-flash-thinking etc. explicitly enable thinking mode.
  • No-thinking variant: gemini-2.5-flash-nothinking etc. explicitly disable thinking.
  • Image / music specialized: mj_imagine, mj_upscale, suno_v3.5.

​
Model changes & retirement

  • Additions: new models are added continuously; the console model list is authoritative.
  • Retirement: when an upstream deprecates a model, OpenPAI announces it 7-14 days in advance and stops accepting new requests.
  • Price changes: multiplier changes are announced 24 hours in advance; orders already generated are settled at the multiplier in effect at call time.
