Libraries

How to use LLM-OS-Models/Fabliq-8B-Agent-FromBase with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="LLM-OS-Models/Fabliq-8B-Agent-FromBase")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("LLM-OS-Models/Fabliq-8B-Agent-FromBase")
model = AutoModelForCausalLM.from_pretrained("LLM-OS-Models/Fabliq-8B-Agent-FromBase", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=256)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Fabliq-8B-Agent-FromBase 🌊🔬

Ablation variant of Fabliq-8B-Agent — fine-tuned directly from raw LiquidAI/LFM2.5-8B-A1B, skipping the ToolBench foundation. Used to isolate the effect of the ToolBench intermediate stage.

🔬 Why this variant?

Fabliq-8B-Agent is trained as: LiquidAI/LFM2.5-8B-A1B → ToolBench-Full-SFT-1Epoch → Fable-5.

This model skips the middle step: LiquidAI/LFM2.5-8B-A1B → Fable-5 (direct).

Comparing the two answers the question: does ToolBench foundation actually help, or does Fable-5 alone give you the same agent?
