```
DeepSeek's Anthropic convention (`convention = "anthropic"`) points at
`https://api.deepseek.com/anthropic` by default and is fully supported by the
agent's Anthropic Messages path (tools, streaming, usage). DeepSeek maps
`claude-opus*` model ids to `deepseek-v4-pro` and `claude-haiku*` /
`claude-sonnet*` (and unknown ids) to `deepseek-v4-flash` server-side; real
`deepseek-v4-*` ids pass through as-is. `GET /models` is not documented on that
base, so model selection is config-driven.
If `[database]` is omitted (or SQLite `url` is unset/empty), chat uses a durable file under the user data dir (e.g. `~/.local/share/plyngent/chat.db` on Linux). Set `url = ":memory:"` for a true in-memory SQLite (CLI warns; no file; useful for tests).
