 The `PEEKABOO_AI_PROVIDERS` environment variable is your gateway to unlocking Peekaboo's analytical abilities. It should be a comma-separated string defining the AI providers and their default models. For example:
 
-`PEEKABOO_AI_PROVIDERS="ollama/llava:latest,openai/gpt-4-vision-preview,anthropic/claude-3-haiku-20240307"`
+`PEEKABOO_AI_PROVIDERS="ollama/llava:latest,openai/gpt-4o,anthropic/claude-3-haiku-20240307"`
 
 Each entry follows the format `provider_name/model_identifier`.
 
 - **`provider_name`**: Currently supported values are `ollama` (for local Ollama instances) and `openai`. Support for `anthropic` is planned.
-- **`model_identifier`**: The specific model to use for that provider (e.g., `llava:latest`, `gpt-4-vision-preview`, `gpt-4o`).

-The `analyze` tool will use these configurations. If the `provider_config` argument in the `analyze` tool is set to `"auto"` (the default), Peekaboo will try providers from `PEEKABOO_AI_PROVIDERS` in the order they are listed, checking for necessary API keys (like `OPENAI_API_KEY`) or service availability (like Ollama running at `PEEKABOO_OLLAMA_BASE_URL`).

 You can override the model or pick a specific provider listed in `PEEKABOO_AI_PROVIDERS` using the `analyze` tool's `provider_config` argument. (The system will still verify its operational readiness, e.g., API key presence or service availability.)

-If you were thinking about this as a more structured configuration, the string `ollama/llava,openai/gpt-4-vision-preview` conceptually maps to something like:
-
-```json
-[

-    "provider": "ollama",
-    "default_model": "llava",
-    "config_needed": "PEEKABOO_OLLAMA_BASE_URL (defaults to http://localhost:11434)"

-    "default_model": "gpt-4-vision-preview",
-    "config_needed": "OPENAI_API_KEY"

-Remember to set the actual `PEEKABOO_AI_PROVIDERS` environment variable as the comma-separated string.
