I keep seeing tool-call syntax in my o4-mini and grok-mini responses. can I add some context to my system prompt to force no tool calls? I think I understand why this wouldn’t render, but it’s wasting tokens.


## o4-mini:

<tool-calling>
{"name":"chart","arguments":{
"type":"lineChart",
"data":{
"labels":[2020,2025,2030,2035,2040],
"series":[
{"name":"Inflation (2%/yr)","data":[100,90.6,82.0,74.3,67.3]},
{"name":"Deflation (-5%/yr)","data":[100,129.1,166.7,215.5,278.6]},
{"name":"Deflation (-11%/yr)","data":[100,177.8,315.8,561.1,997.0]}
]
},
"title":"Purchasing Power Index (2020=100) under Inflation vs AI-Driven Deflation",
"xAxisLabel":"Year",
"yAxisLabel":"Purchasing Power Index"
}}
</tool-calling>

## grok-mini
<tool-calling>
Tool: search
Parameters: {
"query": "global energy consumption for video games 2025 statistics"
}
</tool-calling>
