Method not implemented.

Error message

Method not implemented.

What it means

The DeepSeek adapter intentionally does not implement `list`; model enumeration is unsupported. DeepSeek has only a handful of models, so they are expected to be configured explicitly.

Solutions

1. Configure DeepSeek model IDs explicitly (deepseek-chat, deepseek-reasoner).
2. Call GET https://api.deepseek.com/models directly if live listing is needed.
3. Capability-gate list() calls.

const canList = (p: API): boolean => !(p instanceof DeepSeek);

try { return await deepseek.list(); } catch { return [{ id: 'deepseek-chat' }, { id: 'deepseek-reasoner' }]; }

When it happens

Trigger: Calling .list() on the DeepSeek adapter.

Common situations: Generic provider-health checks or model pickers that call list() on every registered provider.
