Open-source coding harnesses like OpenCode challenge the model triopoly logic
gethackteam · x · 2026-09-05
YuchenjUW and gethackteam debated where coding agent harnesses fit in the AI product landscape. YuchenjUW argued harnesses are a big part of the product, but unlike models—which require hundreds of millions of dollars to train—there are already many great open-source harnesses such as OpenCode, Pi, and Omnigent, meaning the harness layer lacks the capital moat of the model layer. gethackteam pushed back asking how they fit into the triopoly.
