Description
I couldn’t find the AWS Bedrock Sonnet 1M-context model in models.dev, so I created a custom config.
{
"$schema": "https://opencode.ai/config.json",
"model": "us.anthropic.claude-sonnet-4-5-20250929-v1:0[1m]",
"provider": {
"amazon-bedrock": {
"models": {
"us.anthropic.claude-sonnet-4-5-20250929-v1:0[1m]": {
"name": "Claude Sonnet 4.5[1m] (AWS Bedrock)",
"options": {
"thinking": {
"type": "enabled",
"budgetTokens": 16000
}
}
}
}
}
}
}
However, when I initiate the chat, I get an error. Any idea how to resolve this?
When I change the model to "anthropic.claude-sonnet-4-5-20250929-v1:0[1m]", I get this error.

Done means the Sonnet 1M model is represented correctly and can start a chat without either reported error.
