Codex team reportedly ditches context compaction, but only works for models trained on it

Mario Zechner (badlogicgames) observes that the OpenAI Codex team seems to have taken the "abolish all compaction" idea literally in their new release. He finds the new mechanism very interesting but cautions it likely won't work well with models not trained on this mechanism. Context compaction has been the mainstream approach for managing long coding agent sessions, so this direction shift is notable. banteg amplified the take.
