What is glmocr-handwriting?

A tool guide for converting handwritten text in images and PDF files into editable text using the ZhiPu GLM-OCR API. OCR means optical character recognition: software that reads text from pictures.

Use it to read handwritten notes, letters, formulas, labels, annotations, and documents in Chinese, English, or mixed languages.

It removes the need to type handwritten notes manually and can handle mixed handwritten and printed content.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00059	$0.01814
Opus 5	$0.00030	$0.00907
Sonnet 5	$0.00012	$0.00363
Haiku 4.5	$0.00006	$0.00181

Security

Grade A, and why

glmocr-handwriting 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 13d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/glm_ocr_cli.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
