Direct answer
How to use Claude Opus 5 in VUST
Open the direct link and @vustbot first confirms “VUST Opus — Claude Opus 5.” Send a prompt or wait and type later. Pro and Max can run the model inside their allowance; other users keep the prompt while VUST shows the exact one-shot Balance price, pass options, top-up, or an explicit return to the previous available model.

Claude Opus 5 vs Claude Opus 4.8 in VUST
VUST keeps both entries instead of silently renaming the old model. Claude Opus 5 is the new manual preview; Claude Opus 4.8 remains separately selectable. You choose the model explicitly, see its familiar name before the run, and follow-ups stay on that choice until you switch.
What VUST checks before expanding availability
- 1. The documented Claude Opus 5 identity and current $5/$25 API price are checked against current official sources.
- 2. VUST bounds the text response and keeps delivery predictable for a Telegram conversation.
- 3. A model identity mismatch stops the request; VUST does not silently answer with another model.
- 4. Access denial and insufficient Balance preserve the prompt and stop before explicit confirmation.
- 5. Auto does not select this model yet; manual selection remains explicit.
