# prism-coder:32b — Tool Routing Model (Desktop Quality Tier)

Fine-tuned Qwen3-30B-A3B (MoE) for 6-tool routing in the [Prism AAC](https://github.com/dcostenco/prism-aac) system.
Quality escalation tier in the desktop cascade: **14B → 32B → cloud Claude**.

> **v5 (May 2026)**: Switched base from dense Qwen3-32B to Qwen3-30B-A3B (MoE).
> Same accuracy, 9 GB smaller, ~4× faster inference (only ~3B params active per token).

## BFCL Routing Benchmark — v7 (Current)

**Mean: 100.0% PERFECT** (3-seed average, seeds 2027/2028/2029, 102 cases each)

| Category | Count | Description | Accuracy |
|----------|------:|-------------|:--------:|
| aac | 12 | AAC phrase requests → plain text | 100% |
| cmpct | 6 | Ledger compaction | 100% |
| edge | 6 | Multi-step / compound requests | 100% |
| hand | 8 | Agent handoff / relay | 100% |
| info | 5 | General facts → plain text | 100% |
| irrel | 10 | Irrelevant / live queries → plain text | 100% |
| know | 7 | Knowledge base search | 100% |
| load | 9 | Session context loading | 100% |
| pred | 8 | Factual / knowledge queries → plain text | 100% |
| save | 13 | Session ledger save | 100% |
| smem | 12 | Session memory search | 100% |
| tran | 6 | Translation requests → plain text | 100% |

All 12 categories at 100%. No remaining failures.

Eval: MLX inference + thinking, temperature=0, 3-seed mean.
Gate: ≥90% = deploy.

## Full Cascade Benchmark (May 2026)

Individual BFCL scores (MLX, 3 seeds):

| Model | BFCL | Size | Tier |
|-------|------|------|------|
| prism-coder:8b v36 | **100.0% PERFECT** | 4.7 GB | Desktop / Mobile tier |
| prism-coder:14b v36 | **100.0% PERFECT** | 8.4 GB | Desktop primary tier |
| prism-coder:32b v7 | **100.0% PERFECT** | 16 GB | Desktop quality tier |

Cascade eval: **14b → 32b → Claude Opus** (102 cases × 3 seeds)

| Metric | Result |
|--------|--------|
| Cascade accuracy | **100.0%** (mean, 3 seeds) |
| Opus-solo etalon | 98.3% |
| Δ vs Opus | **+1.7%** |
| Traffic served by 14b | **99%** (101/102 cases avg) |
| Traffic escalated to 32b | 1% (1/102 avg) — catches `save live state` → handoff edge case |
| Traffic reaching Opus API | **0%** |

Fine-tuned cascade outperforms Claude Opus on `edge` (+16.7%) and `know` (+14.3%).

## Version History

| Version | Base | BFCL | Notes |
|---------|------|------|-------|
| v7 (current) | Qwen3-30B-A3B MoE | **100.0% PERFECT** | Fixed: "what do I know + search memory" compound → knowledge_search |
| v6 | Qwen3-30B-A3B MoE | 99.0% | Fixed MoE merge (BF16 safetensors + correct MLX→HF key mapping) |
| v5 | Qwen3-30B-A3B MoE | 97.1% | 18× density fix; 9GB smaller, 4× faster vs dense |
| v4 | Qwen3-30B-A3B MoE | 92.2% | rank=32 experiment — regressed vs v3 |
| v3 | Qwen3-30B-A3B MoE | 92.5% | 20× reps + LR=1e-5 — hit rank bottleneck |
| v2 | Qwen3-30B-A3B MoE | 92.5% | v34 corpus + 1400 iters |
| v33 (dense) | Qwen3-32B dense | 99.0% | Prior generation — larger/slower |

## Tools

The model routes between exactly 6 tools:

1. `session_load_context` — load/fetch/resume project context
2. `session_save_ledger` — note/log/remember/record progress
3. `session_save_handoff` — handoff/relay to next agent/session
4. `session_compact_ledger` — compact/archive/shrink ledger
5. `session_search_memory` — recall past sessions/conversations
6. `knowledge_search` — search stored notes/knowledge base

```

## Training

- **Base**: Qwen/Qwen3-30B-A3B (HF BF16, ~57 GB)
- **Adapters**: v6 LoRA (rank=8, scale=10, 8 layers, LR=1e-5)
- **Merge**: Direct safetensors merge on HF BF16 base; delta = (scale/rank) × B^T A^T for attn/gate; delta[i] = (scale/rank) × B[i] A[i] for MoE experts (128 experts stacked)
- **Key fix**: v5 merge used wrong base (MLX 4-bit, can't apply float LoRA delta) and uppercase regex `lora_[AB]` vs actual lowercase `lora_a`/`lora_b` adapter keys
- **Hardware**: Apple Silicon (M-series, 64 GB RAM)
