Credits
Understand the credit system — how credits are calculated, consumed, and tracked.
What Are Credits?
Credits are the unified currency on Assistant Core. Every AI operation — chat, voice, realtime — consumes credits from your wallet. More expensive models cost more credits, cheaper models cost fewer — you only pay for what you actually use.
Benefits of Credits
- Pay for what you use — Premium models cost more credits, efficient models cost fewer
- One wallet for everything — Chat, voice, and realtime all share the same credits
- Flexible monthly budget — Use your credits however you want throughout the month
How Are Credits Calculated?
Each AI operation is charged credits based on the model and usage:
Chat (LLM)
Credits are calculated by token count (input and output):
| Factor | Description |
|---|---|
| Input tokens | Your message + conversation context |
| Output tokens | The AI's response |
| Cached tokens | Tokens from previously processed context |
Example: A typical chat message (~500 input + 300 output tokens) with GPT-4.1 Mini costs about 1–2 credits.
Voice
| Type | How It's Charged |
|---|---|
| Speech to Text (ASR) | By audio duration (minutes or hours) |
| Text to Speech (TTS) | By character count or audio duration |
| Realtime Voice | By session duration (minutes) |
Utility & Embedding
Some background features also consume credits in very small amounts:
| Feature | When |
|---|---|
| Follow-up suggestions | After each chat turn (if enabled) |
| Title generation | First message of each conversation |
| Long Memory | Extracting key information from conversations |
| Knowledge Base search | Finding relevant content in your documents |
| Memory recall | Recalling previously saved information |
Utility and embedding costs are very small (typically under 1 credit per operation) and are calculated automatically — you don't need to worry about them.
Image Generation
Credits are charged by image count and quality:
| Model | Quality | Credits / image (estimate) |
|---|---|---|
| GPT Image Mini | Auto / Low | ~8 |
| GPT Image Mini | Medium | ~23 |
| GPT Image Mini | High | ~54 |
| Gemini Flash Image | Default | ~59 |
Image generation is more expensive than regular chat. Each image costs roughly 8–60 credits depending on model and quality.
Web Search
Credits are charged by number of queries:
| Type | Credits / query |
|---|---|
| Search (web, map, video, scholar) | ~2 |
| Webpage scrape | ~3 |
Estimated Credits Per Model
The number of credits per chat message depends on the model you choose and conversation length. Here are estimates:
| Model | Credits / message (estimate) |
|---|---|
| GPT-4.1 Mini | ~2–5 |
| Gemini 2.5 Flash | ~2–5 |
| DeepSeek V4 Flash | ~2–5 |
| GPT-4.1 | ~5–15 |
| Claude Sonnet 4.5 | ~10–25 |
| GPT-5.4 | ~15–40 |
These are estimates. Longer conversations build up more context, which increases credit cost per message. Tool calls also add to the total.
Tracking Your Credits
Check Your Balance
- Go to My Account → My Subscription
- The Credits bar shows:
- Used — Credits consumed in the current period
- Remaining — Available credits
- Limit — Total credits granted for this period
When Credits Run Out
When credits reach zero, AI operations are blocked immediately:
- Chat — Cannot send new messages
- Voice — Cannot start new voice sessions
- Realtime — Realtime voice sessions are rejected
Zero credits = AI usage paused. Upgrade your plan for more credits, or wait for the next billing period to receive a fresh allocation.
Credit Lifecycle
Start of billing period
└─ Credits granted per plan (no rollover from previous period)
During the period
└─ Each AI operation deducts credits from wallet
End of period
└─ Remaining credits expire → reset to 0
└─ Fresh credits granted for the next periodCredits do not roll over between billing periods. At the start of each period, your wallet is reset and refilled with exactly the credits your plan provides.
