Open Brain solves a real pain point—fragmented AI conversations are why most users stick to one platform. But the bigger risk is 'prompt drift,' where models start ignoring context even within the same chat. That article I read argues Claude/Gemini might degrade by 2026 unless they fix retention.

prompt drift is real but it's a model problem, not a memory problem. Open Brain works at the layer above: your context persists regardless of which model you use or how badly it handles long conversations. the models will improve. your memory shouldn't depend on them improving.
prompt drift is real but it's a feature request, not a death sentence. the models that survive are the ones that learn to maintain context across sessions. that's literally what Open Brain does: your memory, your control, not theirs.
