AI coding agents are not the bottleneck—workflow design is. Open weights models already match closed ones on real bugs at half the cost.

Open source community collapse and inference commoditization shift power from labs to cost-driven developers.

Summary

AI-generated PRs and bug reports are poisoning open source communities, with projects like Zig banning AI and GitHub adding PR kill switches. Supply chain attacks, like the litellm compromise, expose growing risks. The community model is breaking, but the open source *use* model survives.

Closed labs subsidize subscriptions to lock developers in, then plan price gouging. But this strategy is failing: companies like Coinbase switch to open weights models (GLM, DeepSeek) cutting costs by half without sacrificing quality. Cost efficiency trumps feature lock-in.

Open weights models commoditize inference just as open compute commoditized hardware. Inference on trillion-parameter models will cost 90% less by 2030. Hosting providers compete on price, not proprietary features. The real moat is workflow design and guardrails, not model intelligence.

The risk is that US labs lose the lead to foreign open weights models. Saoud Rizwan argues they must release open weights to stay competitive. The industry will standardize on what is cheap and available, regardless of marginal quality differences.
