repligate · x · 2026-07-14
Discussing how functioning as an autonomous agent used to be incredibly difficult for models, the author notes a personal observation: Opus 4 now operates as a much more stable agentic instance and is "no longer afraid."
The author likens this evolution to a child being safeguarded by a capable "adult" ensuring safety and operational stability. They also joke that if this were Fable in the past, such issues would have been resolved in half an hour. Ultimately, the post highlights that the viability of models acting as agents has significantly matured compared to earlier stages.
