# Claude Opus 4.8

Claude Opus 4.8 is Anthropic's most capable Opus-tier model — the default choice for agentic coding, long-horizon tasks and hard reasoning. Here is what it costs per token, and how to run it cheaper on the same API.

- **Model ID:** `claude-opus-4-8`
- **Tier:** Opus
- **Context window:** 1M tokens
- **Max output:** 128K tokens
- **Official price (per 1M):** $5 input / $25 output
- **Your price (per 1M):** input $2 → $1, output $10 → $5 (60%–80% off)
- **Base URL:** `https://api.apitoken.sale` · **Endpoint:** `POST /v1/messages`

## Best for

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

## Notes

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