kairos-door-rain

builtbyd3v

Binary image classifier: `rain` vs `no_rain`, for a camera looking out a dock door. Fine-tuned from facebook/convnext-tiny-224 (Apache-2.0). Part of Kairos, a weather plugin for Boston Dynamics Spot fleets (Knight Hacks IX hackathon build). It feeds one input of a GO / HOLD rule. Python: `pipeline("image-classification", model="builtbyd3v/kairos-door-rain")`. Hold when p(rain) >= **0.4447** for q8, or >= **0.4728** for fp32 (each picked on the calibration split, one image per call). Both are in `eval_results.json` under `thresholds`. 95% CIs are Wilson score intervals. Threshold rule: the highest threshold that keeps calibration rain recall >= 95%, rounded down. Scored with onnxruntime CPU on the shipped ONNX files, one image per call (as in the browser).

spot-wetfloor-convnext-tiny

builtbyd3v

Binary image classifier: `wet` (visible standing water or a wet surface) vs `dry`. Fine-tuned from facebook/convnext-tiny-224 (Apache-2.0). Built for SPOT Dispatch, a readiness board for Boston Dynamics Spot inspection routes. Spot's user guide says not to walk on wet or slippery surfaces, so the board can flag route photos that look wet for an operator to review. `onnx/model_quantized.onnx` (33.8 MB vs 111.4 MB fp32) loads with `{ dtype: "q8" }`. It is onnxruntime `quantize_dynamic`, uint8 weights, MatMul/Gemm layers only (convs stay fp32). Scored with onnxruntime on the same test split: q8 misses one more same-source wet image and changes 1 of 752 test predictions vs fp32 (kit images: same calls). Use fp32 when recall matters more than load time. Quantizing the convs too (28 MB) lost 2 same-source wet images, so it is not shipped.

MODEL HANDBOOK

Understand before you choose

Selection guide & FAQ

How should API prices be compared?+

Separate input, output and cache rates, then estimate the same workload. Image, audio and video rates may use items, duration or resolution rather than tokens.

Do open weights mean free commercial use?+

Not necessarily. Check each version’s license, commercial restrictions and policies. Self-hosting also incurs compute and maintenance costs.

Is the top-ranked model the best for me?+

Rankings depend on tasks, versions and methods. Compare accuracy, latency, reliability and costs on your own workload.
