Theo claims new model hallucinates 10x worse in real codebases; bugs traced to ACP integration

Theo (t3.gg) slammed a new model as "incapable of working in a real codebase without hallucinating in egregious ways — not 5% worse, 10x worse." Per the attached screenshot, Antigravity's Patrick Toulme replied that two bugs in antigravity-acp — an ACP bug in the T3 integration, not a Gemini model issue — were already fixed internally and shipping in the next release, thanking Theo for the repro. A classic case of model-blaming vs toolchain bugs in coding-agent land.
