AI Models

When to use

Use this skill automatically whenever you write code that calls AI APIs and need to specify a model ID.

Triggers:

• Writing API calls to Anthropic, OpenAI, or Google AI
• Setting model parameters in any AI SDK (Vercel AI SDK, LangChain, etc.)
• User asks about latest available models
• Any code involving model: or model= for AI providers

How to use

Run the fetch script — it scrapes public sources, no API keys needed:

bash ~/.claude/skills/ai-models/fetch-models.sh

Options:

• --all (default): All providers
• --anthropic: Anthropic only
• --openai: OpenAI only
• --google: Google Gemini only

Sources:

• Anthropic: official docs page (docs.anthropic.com)
• OpenAI: SDK source of truth on GitHub (auto-generated from OpenAPI spec)
• Google: official Gemini docs (ai.google.dev)

Rules

1. Always run the script before using any model ID in code — never guess or use memorized IDs
2. Use the exact model ID from the script output
3. Pick the right tier for the use case:
   • Flagship (Opus / GPT-4o / Gemini Pro): Complex reasoning, high quality
   • Balanced (Sonnet / GPT-4o-mini / Gemini Flash): Best speed/quality ratio, default choice
   • Fast (Haiku / GPT-3.5 / Gemini Flash Lite): Speed-first, simple tasks, cost-effective
4. Prefer aliases (e.g. claude-sonnet-4-5) over dated versions unless pinning is needed
