The PII spans never need to stay in plain text. + +**Cheap router in front of Claude.** Use a zero-shot or structured classification to triage an incoming message (bug / feature / question, urgent / normal) and only escalate the hard cases to Claude's own reasoning. The classifier call costs a fraction of a full Claude turn. + +**Structured extraction over free-form parsing.** For semi-structured text (signatures, invoices, contact blocks), prefer JSON extraction over asking Claude to "parse this into JSON." It's deterministic on the schema, faster, and cheaper. + +### Task reference + +| Task | Model | Example prompt | +| --- | --- | --- | +| Summarize | `llama-3.1-8b-instruct-fast` | "Summarize this with ZeroGPU: ..." | +| Zero-shot classify | `deberta-v3-small` | "Classify this as positive, negative, or neutral with ZeroGPU: ..." | +| Multi-axis classify | `gliner2-base-v1` | "Classify by sentiment and topic with ZeroGPU: ..." | +| IAB classify | `zlm-v1-iab-classify-edge` | "What IAB category is this, using ZeroGPU? ..." | +| Detect PII | `gliner-multi-pii-v1` | "Detect PII in this text with ZeroGPU: ..." | +| Redact PII | `gliner-multi-pii-v1` | "Redact the PII in this with ZeroGPU: ..." | +| Extract entities | `gliner2-base-v1` | "Extract the people and organizations with ZeroGPU: ..." | +| Extract JSON | `gliner2-base-v1` | "Extract the name, email, and phone as JSON with ZeroGPU: ..." | + ## Notes -- Requires a ZeroGPU API key. -- Claude will ask for your credentials if they're missing. -- Make sure your machine has network access to `api.zerogpu.ai`. +- **An API key is required.** Claude will ask for your ZeroGPU API key before running any inference, and won't proceed without it. +- **Providing the key in Claude Web.** In Claude Web there's no settings store for the Skill, so you supply the API key directly in the chat when Claude asks for it. It's used for that conversation's API calls only; paste it as its own message and avoid sharing the transcript. For anything beyond interactive use, prefer Claude Desktop or a server-side integration. +- **No fabricated results.** Every result comes from a live API call to the real model. Claude won't guess a classification or invent extracted data before the call runs; if it can't make the call, it says so. +- **Only real models.** The Skill pins Claude to the actual [model catalog](/docs/model-catalog). It won't reference models, parameters, or pricing that don't exist. +- **Network access.** Make sure your machine can reach `api.zerogpu.ai`. +- **Keep secrets server-side for production.** The Skill is for interactive use in Claude (Desktop or Web). For app and agent integrations, read your API key from environment variables or a secrets manager rather than pasting it into a chat. See [Production patterns](/docs/production-patterns).
