Describe the enhancement you want to request
When having multiple variants of an model configured.
it would be good to have the agent config point to a specific model variant.
// Global Model Configuration
"anthropic/claude-sonnet-4-5": {
"name": "anthropic/claude-sonnet-4-5",
"variants": {
"thinking": {
"thinking": {

"budget_tokens": 1600
},
"max_tokens": 2000
},
"fast": {
"thinking": {
"type": "disabled"
}
}
}
}would result in something like

You are a security expert. Focus on identifying potential security issues.
Analyze the provided code and identify vulnerabilities such as SQL injection,
XSS, or insecure dependency versions.
when i use a config with variants an did not specify any it takes the default model but that seems to prefer thinking.
it errors with
{"message":"The model returned the following errors: messages.1.content.0.type: Expected `thinking` or `redacted_thinking`, but found `text`. When `thinking` is enabled, a final `assistant` message must start with a thinking block (preceeding the lastmost set of `tool_use` and `tool_result` blocks). We recommend you include thinking blocks from previous turns. To avoid this requirement, disable `thinking`. Please consult our documentation at https://docs.claude.com/en/docs/build-with-claude/extended-thinking"}. Received Model Group=anthropic/claude-4-5-sonnet
Available Model Group Fallbacks=Non
when i use a simpel model config

"name": "anthropic/claude-4-5-sonnet",

"thinking": {

it does work! it takes that model and performs the actions as the security auditor.
