Rolodex-12B
Rolodex-12B (12B active / 106B total MoE parameters, GLM-4.5-Air derivative) is a search model: fine-tuned for agentic, tool-driven retrieval over personal and team knowledge bases — multi-step search, memory lookup, and evidence synthesis with tool use.
Lineage
- Base: zai-org/GLM-4.5-Air (MIT)
- This model: LoRA fine-tune (r=32, α=64) with OAPL on agentic search trajectories, merged into the base weights.
This repo contains the fully merged weights, plus the LoRA adapter under
adapter/. Because the base is the public GLM-4.5-Air, the adapter can also be
applied directly to the base model (see adapter/README.md, including the
router-bias step).
Rolodex-12B is also the stage-1 base of PolyClerk-12B, our legal work-product model.
Training
| Method | OAPL, LoRA r=32 / α=64 (merged) |
| Framework | ms-swift (Megatron backend) |
| Epochs | 1 |
Evaluation
On internal short-factoid retrieval QA over indexed knowledge bases, the OAPL-trained model improves materially over the GLM-4.5-Air base while using single-tree guided search (fewer tool calls than majority-vote baselines). Internal numbers; independent benchmarks pending.
Usage
Requires ~200GB of weights (bf16). Serve with vLLM:
vllm serve polygramme/Rolodex-12B --tensor-parallel-size 4 --max-model-len 131072
The chat template is included (chat_template.jinja). The model is trained for
tool-use loops (search/read tools) — it performs best inside an agentic harness
that exposes retrieval tools, rather than as a plain chat model.
Intended use & limitations
Intended for retrieval-augmented and memory-augmented agent workloads. It may underperform general instruction models on open-ended chat. Verify retrieved claims against sources; the model can still hallucinate under sparse retrieval.
