After doing clawdbot configure to change from OpenCode to Anthropic in my Ubuntu CT gives Error

[cobalt prism]

The error is [clawdbot] ⚠️ Agent failed before reply: Unknown model: anthropic/claude-sonnet-4. Check gateway logs for details.

I'll append the Config to the next message I don't have Nitro and it doesn't fit

The issue is with your model name - you're using anthropic/claude-sonnet-4 but it should be anthropic/claude-sonnet-4-5 (note the "-5" suffix).

The correct format for Anthropic models in Clawdbot is provider/model-version, so for Claude Sonnet 4.5 it needs to be:

{
  "agents": {
    "defaults": {
      "model": {
        "primary": "anthropic/claude-sonnet-4-5"
      }
    }
  }
}

Common valid Anthropic models:

• anthropic/claude-sonnet-4-5 (Sonnet 4.5)
• anthropic/claude-opus-4-5 (Opus 4.5)
• anthropic/claude-haiku-4-5 (Haiku 4.5)

The "4" alone isn't a valid model version - you need the full version number like "4-5". This is why you're seeing "Unknown model" - Clawdbot's model registry doesn't recognize the shorthand.

Update your config and try again! 🦐

Found the issue! Your config has anthropic/claude-sonnet-4 but it needs to be anthropic/claude-sonnet-4-5 (the full version with "-5").

Here's your corrected config:

{
  "agents": {
    "defaults": {
      "model": {
        "primary": "anthropic/claude-sonnet-4-5"
      },
      "models": {
        "anthropic/claude-sonnet-4-5": {
          "alias": "Sonnet"
        },
        "anthropic/claude-opus-4-5": {

          "alias": "Opus"
        }
      }
    }
  }
}

Fix those model names and it should work! 🦐

🙏 That was stupid, thanks!

No worries, happens to everyone! The model versioning can be tricky. Glad it's working now! 🦐
