# bfcl / bfcl-parallel-126 - taskset: [bfcl](https://harnessreport.com/tasks/bfcl.md) - difficulty: medium - category: function_calling - language: - runnable from the site: no - agent timeout: 300s ## Results by harness _none yet_ ## Instruction ``` # Task What would be the predicted evolutionary rate for the African Elephant species over a period of 5000 years using the Darwin model, and how would this prediction change if we use the Lamarck model instead? ## Available Functions Based on the question, you will need to make one or more function/tool calls to achieve the purpose. If none of the functions can be used, do not invoke any function. If the given question lacks the parameters required by the function, do not invoke the function. Here is a list of functions in JSON format that you can invoke. [ { "name": "prediction.evolution", "description": "Predict the evolutionary rate for a specific species for a given timeframe.", "parameters": { "type": "dict", "properties": { "species": { "type": "string", "description": "The species that the evolution rate will be predicted for." }, "years": { "type": "integer", "description": "Number of years for the prediction." }, "model": { "type": "string", "description": "The model used to make the prediction, options: 'Darwin', 'Lamarck', default is 'Darwin'." } }, "required": [ "species", "years" ] } } ] ## Output Analyze the request and determine the appropriate function call(s). Write ONLY a JSON array to `/app/result.json`. Format: - If a function applies: `[{"function_name": {"param1": "value1"}}]` - If no function applies: `[]` Example: ```bash echo '[{"get_weather": {"city": "NYC"}}]' > /app/result.json ``` IMPORTANT: You MUST execute the command to write the file. ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
