Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

individual-tax scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

个人所得税

概述

中国的个人所得税分为综合所得(工资薪金/劳务报酬等)和经营所得(个体工商户/个人独资企业等)两大类。小企业常见的场景包括:给自己发工资、给员工发工资、个体工商户经营所得申报。

一、综合所得(工资/劳务报酬)

税率表(七级累进)

级数 全年应纳税所得额 税率 速算扣除数
1 ≤ 36,000 3% 0
2 36,000 ~ 144,000 10% 2,520
3 144,000 ~ 300,000 20% 16,920
4 300,000 ~ 420,000 25% 31,920
5 420,000 ~ 660,000 30% 52,920
6 660,000 ~ 960,000 35% 85,920
7 > 960,000 45% 181,920

计算公式

应纳税所得额 = 累计收入 - 累计减除费用(5000/月) - 累计专项扣除 - 累计专项附加扣除
应纳税额 = 应纳税所得额 × 税率 - 速算扣除数 - 累计已缴税额
