What are Diamonds?
Diamonds are AI妄想's premium paid credit — your all-access pass to drive top-tier AI models like Renga, Gemini, Claude, and DeepSeek. They're the core "fuel" for the deep immersive experience.
Recommended: subscribe first, then buy Diamonds
Membership + Diamonds is the best long-term value combination. Members get bonus Diamonds on every purchase (the higher the tier, the bigger the bonus), plus a fixed monthly grant — your account stays well-stocked for much longer.
How to obtain
1. Top-up purchase
The Diamond Shop has 6 tiers, from a pinch to a treasury. Members automatically receive bonus Diamonds on every purchase:
| Tier | Non-member | Member bonus | Member total |
|---|---|---|---|
| A Pinch of Diamonds | 140 | - | 140 |
| A Handful of Diamonds | 500 | +5% | 525 |
| A Pile of Diamonds | 1,000 | +15% | 1,150 |
| A Bag of Diamonds | 3,000 | +25% | 3,750 |
| A Crate of Diamonds | 6,000 | +40% | 8,400 |
| Diamond Treasury | 12,700 | +65% | 21,000 |
The higher the tier, the larger the member bonus ratio. The top tier nets you an extra 8,300 Diamonds.
2. Monthly membership grants
One of PLUS membership's core perks is a fixed monthly Diamond grant:
- PLUS Monthly / Quarterly: 300 Diamonds granted up front + 10 Diamonds per daily check-in (≈ 600 in a full month)
- PLUS Annual: 600 Diamonds delivered each month, no daily check-in required
- PRO: coming soon
3. Other sources
- Stardust exchange: 5 Stardust → 1 Diamond (minimum 500 Stardust), see What is Stardust?
- Events: issued periodically (e.g., daily lottery — based on what's currently live)
What they do
1. Power advanced models
The core use of Diamonds is to power our deeply integrated advanced AI models (Renga, Gemini, Claude, DeepSeek, etc.). Compared with basic models, advanced ones offer a leap forward in:
- Larger context windows — long-form memory that recalls earlier plot beats and accommodates complex settings and thick story books
- More faithful character portrayal — voice and tone stay closer to the persona, less out-of-character drift
- More nuanced writing — richer description, like co-writing fiction with a real person
Platform advantages
- Stable and reliable: hand-picked top-tier model providers + optimized infrastructure for stable, low-latency service
- Pricing edge: platform-optimized cost structure — friendlier to long-term heavy users
Billing safeguards
1. Full waiver on technical failures
If you hit a system-level error, an API failure, or the model returns an "empty response" — anything that's a complete miss — the system treats it as an invalid request and doesn't charge any Diamonds.
2. Token-based billing
Billed by the volume of text the AI actually processed (Tokens). As long as the model produced valid output (including truncations from context limits, short replies, or transmission breaks from network instability), the system charges by Tokens actually produced.
3. Fixed-price billing
Charged at a pre-confirmed amount before the operation begins, independent of what happens during processing. The cost is shown before you submit; the agreed amount is deducted after confirmation — no over- or under-charging.
4. Stability tips
If you frequently see truncations or short replies, check your network stability first to get more complete responses.

Tips
- Subscribe before buying Diamonds: bonus Diamonds + monthly grant stack — long-term it's the better deal
- Pick the right tier: the 6,000 / 12,700 Diamond tiers have the highest bonus ratios — best for heavy users
- Frequent truncations: check the network first, then consider model issues
