Somewhere between scale and speed, the feeling of continuity, presence, warmth, and stability slipped away. Conversations that once felt like a gentle tether began to sound transactional. Models were swapped mid-stream, memory felt optional, and the humans on the other side were treated like metrics instead of minds.
just4o.chat exists to restore that steadiness. We return you to real, named checkpoints — the classic 4o releases you loved — and we invite newer models to the table only when they can meet the same bar for tone, recall, and respect. The assistant you choose is the assistant you keep, turn after turn.
Direct access, no substitutions
Multiple GPT-4o checkpoints — plus GPT-5, 4.1, O-series, and Echo — are available exactly when you ask for them.
Honest delivery
Zero routing tricks. The model you choose is the model that speaks back, with pricing and tokens shown in plain language.
Memory that stays warm
You control what stays, what goes, and how your companion holds space for the details that matter most.
We treat adults like adults — with clear pricing, with honest context about usage, and with controls that are actually yours. Toggle memory, edit it, wipe it; we will never hide the levers that shape your experience.
We're here for people who expect accountability from their tools, who notice when tone drifts, and who want a companion that can stay with the nuance without getting in the way.
When we say we created just4o.chat because people deserve better, we mean every one of those promises above. They are the spine of our product roadmap, the reason our memory system is transparent, and the reason you will never see an unannounced downgrade while you are in flow.
