| # Haste Jev 5m (Medium) |
|
|
| **Role:** Finance / KYC workflow branch |
|
|
| Open-weights **System-1 decision engine** for software paths that need typed |
| decisions under a time budget (agent routing, tool routing, intent classification, |
| pre-flight guardrails, browser action selection). Not a chat model. |
|
|
| ## Measured specification |
|
|
| | Field | Value | |
| |---|---| |
| | Total parameters | 5,003,971 | |
| | Trainable parameters | 3,369,667 | |
| | Hash-table buffers | 1,634,304 | |
| | d_model | 224 | |
| | Layers | 5 | |
| | Heads | 4 | |
| |
| Parameter counts match the GitHub README table (verified with `verify_claims.py`). |
|
|
| ## Honest claims |
|
|
| | Claim | Status | |
| |---|---| |
| | PICA option-order bias = 0.0% | **Verified** architecturally | |
| | Exact parameter table | **Verified** | |
| | FP32 ~0.4 MB for 100k weights | **Verified** (weight storage only) | |
| | p99 < 15ms / ECE < 0.009 / 99.4% arithmetic | **Not verified** — do not cite from this card | |
| | Published latency / accuracy on your workload | **Measure yourself** | |
|
|
| Weights may be lightly or untrained prototypes depending on export; treat behavioral |
| accuracy as unknown until you evaluate on labeled data. |
|
|
| ## Quickstart |
|
|
| ```python |
| from hastejev import HasteJevEngine |
| |
| eng = HasteJevEngine.from_pretrained("noffy/hastejev-5m") |
| # eng = HasteJevEngine.from_pretrained("noffy/hastejev-5m", quantization="int4") |
| |
| r = eng.choice( |
| "Request: reset password for user@corp.example", |
| ["auth_self_service", "billing", "security_review"], |
| ) |
| print(r.decision, r.confidence) |
| ``` |
|
|
| Install: `pip install git+https://github.com/racstan/hastejev.git` |
