# K2.5 Emergency Model Switch

**Status:** PREPARED - NOT ACTIVE
**Purpose:** Backup if Anthropic credits run out

## K2.5 Model Details
- **Provider:** Fireworks.ai
- **Model ID:** `accounts/fireworks/models/kimi-k2p5` (verified available)
- **Also available:** `kimi-k2-instruct-0905`, `kimi-k2-thinking`
- **Context:** 128k tokens
- **Max output:** 8192 tokens
- **Cost:** ~$0.40/M input, ~$1.60/M output (10% of Opus)

## To Activate (Emergency Only)

### Option 1: Per-session override (temporary)
```
/model fireworks/accounts/fireworks/models/kimi-k2p5
```

### Option 2: Set as default for main agent
Add to `agents.list[0]` (main agent):
```json
{
  "id": "main",
  "model": "fireworks/accounts/fireworks/models/kimi-k2p5",
  "identity": {
    "name": "James",
    "emoji": "⚡"
  }
}
```

### Option 3: Full config patch (adds K2.5 to providers + sets default)
Run this command:
```bash
openclaw gateway config.patch --raw '{
  "models": {
    "providers": {
      "fireworks": {
        "models": [
          {
            "id": "accounts/fireworks/models/kimi-k2p5",
            "name": "Kimi K2.5",
            "reasoning": false,
            "input": ["text"],
            "cost": {"input": 0.40, "output": 1.60, "cacheRead": 0, "cacheWrite": 0},
            "contextWindow": 128000,
            "maxTokens": 8192
          }
        ]
      }
    }
  },
  "agents": {
    "defaults": {
      "model": "fireworks/accounts/fireworks/models/kimi-k2p5"
    }
  }
}'
```

## K2.5 Limitations vs Opus
- Smaller context (128k vs 200k)
- Less nuanced reasoning
- May struggle with complex multi-step tasks
- **Good for:** Straightforward coding, simple Q&A, routine tasks
- **Not ideal for:** Complex judgment calls, nuanced conversation

## Rollback to Anthropic
```bash
openclaw gateway config.patch --raw '{
  "agents": {
    "defaults": {
      "model": "anthropic/claude-opus-4-5"
    }
  }
}'
```

Or per-session: `/model anthropic/claude-opus-4-5`
