prism-coder:1.7b — Tool Routing Model (Always-Fits Tier)

Fine-tuned Qwen3-1.7B for 6-tool routing in the Prism AAC system. Primary deployment: any iOS device via llama.cpp GGUF — the guaranteed fallback for all device tiers.

BFCL Routing Benchmark — v42 (Current)

Mean: 100.0% (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%

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

Version History

Version	BFCL	Notes
v42	100.0%	Fixed 4 deterministic failures: cmpct tool name, compound edge, write-code irrel, pull-context load
v41	96.1%	Proper safetensors merge — fixes mlx_lm.fuse LoRA loss
v36	94.1%	LoRA rank=16, all 28 layers, mask-prompt
v19	~88%	Baseline 1.7B routing

Tools

The model routes to exactly 6 tools:

Tool	Trigger
`session_load_context`	Load/resume/pull project context
`session_save_ledger`	Note/log/record/remember something
`session_save_handoff`	Pass state to next agent/session
`session_compact_ledger`	Compact/shrink/prune ledger
`session_search_memory`	Recall prior session discussions
`knowledge_search`	Search stored knowledge base ("what do I know")

Plain text (no tool) for: AAC phrases, translations, weather, general facts, code/regex/functions, math.

Model Details

Base: Qwen/Qwen3-1.7B
Format: GGUF Q4_K_M (~1.2 GB)
Context: 32,768 tokens
Training: MLX LoRA, rank=16, all 28 layers, 800 iters, LR=5e-5, v42 corpus (1028 train / 79 valid)
Merge: direct safetensors merge (scale/rank × B.T @ A.T) → llama.cpp convert → Q4_K_M quantization

Usage
