Missing ONNX operators: implementation cost estimates

Rough estimates of the cost of implementing the ONNX operators listed as unsupported in the operator tracking issue, based on the ONNX operator specs. Last updated: 2026-07-12.

How to read the estimates

Complexity is Small / Medium / Large, judging spec surface area

rten ONNX Panic Fuzzing — Findings

Goal: find ONNX models that make cargo run -p rten-cli -r -- <model> panic or crash (not return a clean error). A panic where ONNX Runtime returns a clean error still counts as a robustness bug. Clean Err returns from rten do not count.

Harness: /tmp/rten-fuzz/ — harness.py builds models, runs ORT (validity check) then rten, and flags crashes. Binary: target/release/rten.

Severity scale

Session Prompts

Review the code for the ocrs-cli crate which is a CLI tool for OCR. Then make a plan to implement a new feature which will allow processing images taken from the system clipboard. The feature should be behind a clipboard Cargo feature which is disabled by default. To read from the clipboard, the arboard crate (https://docs.rs/arboard/latest/arboard/) should be used.
`Implement the following plan:
