Fabliq-8B-Agent-FromBase-Reasoning
LLM-OS-Models/Fabliq-8B-Agent-FromBase-Reasoning
Fabliq-8B-Agent-FromBase-Reasoning is a text generation model from LLM-OS-Models. Use it when you need the model to write or continue text. It is set up for transformers. The card lists the license as apache-2.0.
Reasoning-expanded sibling of Fabliq-8B-Agent-FromBase. Adds general + deep reasoning (WithinUs + Helio) on top of the FromBase agentic foundation. Mirrors Fabliq-8B-Agent-Reasoning but for the FromBase ablation lineage.

Fabliq-8B-Agent-FromBase-Reasoning 🌊🔬🧠
Reasoning-expanded sibling of Fabliq-8B-Agent-FromBase. Adds general + deep reasoning (WithinUs + Helio) on top of the FromBase agentic foundation. Mirrors Fabliq-8B-Agent-Reasoning but for the FromBase ablation lineage.
🔬 Why this variant?
Two parallel lineages, both end with reasoning expansion:
| Lineage | Phase-1 | Phase-2 |
|---|---|---|
| ToolBench line | Fabliq-8B-Agent (ToolBench → Fable-5) | Fabliq-8B-Agent-Reasoning |
| FromBase line (this) | Fabliq-8B-Agent-FromBase (base → Fable-5) | Fabliq-8B-Agent-FromBase-Reasoning (this) |
Comparing the two Phase-2 endpoints answers: does ToolBench foundation matter for the final reasoning model, or is Fable-5 + reasoning enough?
