Register a custom LLM endpoint with your own API key for chat in Starchild. Use when adding a personal Anthropic, OpenAI, Grok, Qwen, DeepSeek, Meta (Muse Spark), NEAR AI, or Venice key as a chat model (e.g. add my Claude key, register DeepSeek, use Muse Spark 1.1).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 🔑 BYOK — Custom LLM Models Register a custom LLM endpoint to the model selector. Bypasses the platform proxy — the user supplies their own API key, the agent hits the vendor / aggregator directly (OpenRouter, DashScope, Anthropic native, NEAR AI Cloud TEE, self-hosted, etc.). This is a **script-mode skill** — no tools registered. Read this file, then call the exports from a `bash` block. ## See also - `config/context/references/model-onboarding.md` — broader model selection / OAuth context - `chatgpt-codex-onboarding` skill — for ChatGPT/Codex OAuth (different mechanism, NOT BYOK) --- ## Curated vendors (always check this first) The skill ships with 12 pre-configured vendors. **Always match the user's intent against this list before asking for any URL, model name, or API example** — base_url / wire / thinking / capabilities are all pre-filled, so a curated match goes straight to `add_template(vendor=...)`. | Vendor id | Use when user mentions… | |---|---| | `anthropic` | Claude, Anthropic | | `openai` | GPT-4o, GPT-5, OpenAI direct | | `xai` | Grok, xAI | | `qwen` | Qwen, 通义千问, DashScope | | `deepseek` | DeepSeek | | `kimi` | Kimi, Moonshot | | `mimo` | MiMo, 小米 | …

How to install
mdr add starchild-ai-agent/official-skills/byok-custom-model@sha256:b94fc016605f20b0The line at the top of this page pins the label v2.4.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
