# AI Models > Fetch latest AI model IDs from Anthropic, OpenAI, and Google APIs to use accurate model names in code Use when this capability is needed. - Skill: `tomevault-io/ai-models` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/ai-models` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/ai-models/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: AI & ML - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/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 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 --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/tontoon7) — claim your Tome and manage your conversions.
