d1-3B
d1-3B is an open-weight decision model from Liquid AI (LFM Open License v1.0, 3.1B parameters): it answers typed questions, such as yes or no, pick one or pick several, with probabilities instead of writing text. There's no hosted version: you run it on your own hardware. It scores 49.5 (self-hosted; seconds are the board's estimate) on the independent JevBench Capability Score (board v1.7.46), where Jev, the reference, scores 77.1.

d1-3B benchmarks
| Benchmark | Result | What it measures | Reported by |
|---|---|---|---|
| JevBench v1.7.46 | 49.5 | Capability Score: accuracy and calibration on typed decisions, with Jev as the reference system | Independent |
| JevBench time | 0.18 s | Seconds per decision: measured end to end for hosted APIs, the board's estimate for self-hosted models | Independent |
| Reported speed | 8 ms a decision on an NVIDIA RTX 4090, 16 ms on a Jetson AGX Thor | Latency on the maker's own hardware | Liquid AI |
Makers' speeds are measured on their own hardware and aren't comparable with each other or with JevBench's timings.

d1-3B FAQ
How much does d1-3B cost?
d1-3B has no hosted, per-token price: you download it and run it yourself, so the cost is your own compute.
Is d1-3B open weight?
Yes. Liquid AI publishes the weights under LFM Open License v1.0, so you can run and fine-tune it yourself.
How fast is d1-3B?
Liquid AI reports 8 ms a decision on an NVIDIA RTX 4090, 16 ms on a Jetson AGX Thor, measured on its own hardware. JevBench gives 0.18 seconds per decision, its estimate for self-hosting.
How does d1-3B compare with Jev?
On JevBench's Capability Score (board v1.7.46), d1-3B scores 49.5 against Jev's 77.1. Jev costs $0.042 per million input tokens; d1-3B is self-host only. JevBench is a one-person project that uses Jev as its reference, which favours cheap hosted models.
