Training
Fred-9B was fine-tuned for 300 steps. The training run used a
2,048-token context length and a batch size of 4.
The learning-rate schedule used a short warmup followed by decay across
the training run.
Final Training Metrics
- Training loss:
0.0833
- Learning rate:
7.41e-7
- Gradient norm:
0.470
- Tokens processed:
3,214,912
- Steps:
300 / 300
- Training time:
1h 32m 45s
No evaluation dataset was configured for this training run, so an
evaluation loss was not recorded.
Example Behavior
One of the training checkpoints was tested with simple arithmetic and
order-of-operations questions.
Example 1
Prompt
Please solve this for me i need help: 2+1*3(1+1)+3
Fred-9B
The model correctly handles the parentheses and multiplication before
addition:
1 + 1 = 2
3 × 2 = 6
2 + 6 + 3 = 11

Example 2
Prompt
Please solve this for me i need help: 3+1+1*4(1+1)+3*1
Fred-9B
The model breaks the expression down using standard order of operations
and reaches the correct result.

Intended Use
Fred-9B is intended for:
- Conversational AI experiments
- Local LLM experimentation
- Coding and reasoning experiments
- Mathematical/problem-solving prompts
- Testing fine-tuning workflows
- Personal/local AI assistants
Because Fred-9B is an experimental fine-tune, its behavior may vary
substantially depending on the prompt and task.
Limitations
Fred-9B has several important limitations:
- The model has only been fine-tuned for a relatively small number of
steps.
- The reported run did not use an evaluation dataset.
- The examples shown above are not a comprehensive benchmark.
- Correct answers on simple arithmetic do not guarantee reliable
mathematical reasoning.
- The model may hallucinate or produce incorrect information.
- Fine-tuning can alter some of the capabilities and behaviors of the
original Qwen model.
- Performance will depend on the inference engine, quantization,
prompt format, and hardware.
For serious evaluation, use a held-out evaluation dataset and
established benchmarks rather than relying only on training loss.
Recommended Evaluation
For future versions of Fred, consider evaluating:
- General instruction following
- Mathematical reasoning
- Coding
- Knowledge/retrieval
- Multi-step reasoning
- Hallucination resistance
- Long-context behavior
- Conversational consistency
A separate validation/evaluation dataset should be configured for future
training runs so that training loss can be compared against evaluation
loss.
Running Fred-9B
Fred-9B can be used with an inference stack that supports the model's
exported format.
If the model is exported to GGUF, it can be used with compatible local
inference tools such as llama.cpp-based applications.
Example concept:
# Example only — replace with the actual exported model filename
./llama-cli -m Fred-9B.gguf
The exact command depends on the exported model format and inference
framework.
Quantization
For local deployment, quantized versions can significantly reduce memory
requirements.
Possible variants include:
- 4-bit
- 5-bit
- 6-bit
- 8-bit
- Full/half precision
The best choice depends on available VRAM/RAM and the desired balance
between speed, memory usage, and model quality.
