## Training Objective
|
| 25 |
-
|
| 26 |
-
This model is trained to improve **multi-turn agent task performance**
|
| 27 |
-
on ALFWorld (household tasks) and DBBench (database operations).
|
| 28 |
-
|
| 29 |
-
Loss is applied to **all assistant turns** in the multi-turn trajectory,
|
| 30 |
-
enabling the model to learn environment observation, action selection,
|
| 31 |
-
tool use, and recovery from errors.

## Usage
|
| 27 |
+
Since this is a merged model, you can use it directly with `transformers`.
|
| 28 |
```python
|
| 29 |
from transformers import AutoModelForCausalLM, AutoTokenizer
|
| 30 |
import torch
|
| 31 |
|

+
model_id = "hara-CU/Advanced_FinalCandidate_482"
