Example request

curl https://api.empiriolabs.ai/v1/chat/completions \
  -H 'Authorization: Bearer $EMPIRIOLABS_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"model": "mimo-v2-6-pro", "messages": [{"role":"user","content":"Hello"}]}'

Parameters

Parameter	Type	Required	Default	Description
`enable_thinking`	boolean	no	true	Enable extended thinking mode. Slower but improves reasoning-heavy tasks.
`tool_web_search`	boolean	no	false	Allow the model to perform web searches when needed. Adds $0.015 to the request cost for each invoked call.
`web_search_force`	boolean	no	false	Force the model to always run a web search before answering.
`web_search_max_keyword`	number	no	`3`	Max number of keywords the model can use across web searches. · Range: 1 – 5
`web_search_limit`	number	no	`5`	Max number of web searches the model can perform per request. One request can run more than one search. · Range: 1 – 10
`temperature`	number	no	`0.7`	Sampling temperature. 0 = deterministic, 2 = maximum randomness. · Range: 0 – 2
`top_p`	number	no	`0.9`	Nucleus sampling probability mass. Lower = more focused. · Range: 0 – 1
`max_tokens`	number	no	`4096`	Maximum tokens in the response. · Range: 1 – 131072
`stop`	string	no	-	Up to 4 strings where the model will stop generating further tokens.
`response_format`	enum	no	-	Constrain the output to valid JSON. Use JSON mode for any JSON object, or supply a JSON Schema to force an exact response shape.
`disable_formatting`	boolean	no	false	Skip the EmpirioLabs Markdown formatting (citation [N] rewriting + References block when web search was used). The raw upstream answer with plain [N] citations is returned.

Notes

Web search ($0.015/call) is charged only when invoked. Accepts text, image, video, and audio input and returns text. Thinking is on by default and can be turned off. Sustains complex autonomous workflows with 1000+ tool calls on a 1M context.

Per-tool billing (usage.tool_usage)

When this model invokes tools (web search, code interpreter, etc.) inside a single request, the response carries a normalized usage.tool_usage map alongside the token counts. The example below shows the shape, exact field names, units, and which tools appear can vary slightly per provider:

"usage": {
  "prompt_tokens": 123,
  "completion_tokens": 456,
  "cost_usd": 0.0042,
  "tool_usage": {"web_search": 3, "code_interpreter": 1}
}

The tool counts are already factored into cost_usd, they are surfaced for transparency so you can audit per-tool billing. The field is omitted when no tools were invoked.
