 ### Configuration options
 
-- **`llm`** — main LLM configuration. Optional keys include `temperature`, `max_tokens`, `timeout`, `reasoning_effort`, and `stream`. Values such as `reasoning_effort` are passed to the API as-is when set. `run --no-stream` overrides `stream`.
+- **`llm`** — main LLM configuration. Optional keys include `temperature`, `max_tokens`, `timeout`, `reasoning_effort`, `stream`, and `supports_image_input`. Values such as `reasoning_effort` are passed to the API as-is when set. `run --no-stream` overrides `stream`. `supports_image_input` (default `false`) controls whether `@path` image attachments are sent to the model or stripped with a warning.
 - **`models`** — named LLM profiles for runtime switching with `/model`. A profile is a partial settings dictionary; unset keys inherit from the main `llm`. `default` restores the main LLM configuration.
 - **`context_windows`** — optional per-model context-window overrides (tokens). Keys are model names or substrings (e.g., `deepseek-v4`); matched in file order, first match wins. Overrides the built-in `CONTEXT_WINDOWS` table in `config.py`.
-- **`image_input_models`** — optional list of additional model names or substrings (matched case-insensitively) that accept image input, layered on top of the built-in `IMAGE_INPUT_MODELS` table in `config.py`. Add a model here so `@path` image attachments are sent to it instead of stripped with a warning.
 - **`subagent_llm`** — LLM configuration for `Agent` tool requests. Unset values inherit from the main `llm`. Set `profile` to reuse a profile from `models`. Precedence is: profile settings > explicit `subagent_llm` settings > main `llm` > environment variables.
 - **`default_agent`** — name of the agent to use at session start (instead of the built-in `agent.md`). The agent must exist as a `.md` file in the `prompts/agents/` directory. When unset or `null`, the built-in default agent is used. Use `/agent default` in the TUI to switch back to the built-in at any time.
 - **`paths.context_path` / `paths.skill_path`** — locations from which to load context files and skills. When unset, the project-local `<project>/contexts` and `<project>/skills` directories are used.
