Every request is metered at the official rate first, then your progressive B2C discount (60% at the start, up to 80% as cumulative top-ups grow) is subtracted before it touches your prepaid balance. Context window: 1M tokens. Max output: 128K tokens.

Best for

  • Agentic coding in Claude Code, Cursor and Cline.
  • Long-horizon autonomous tasks and complex refactors.
  • The hardest reasoning, planning and review work.

Good to know

  • Adaptive thinking is the recommended mode; thinking tokens bill as output.
  • 1M-token context window at standard pricing — no long-context premium.
