Freddy pricing is based on synapses (output generation) and neurons (input processing) consumed by each request. This lets you pay precisely for what you use.
- Neurons — Units of input processing. Every token in your messages, thread history, system prompt, and file context consumes neurons.
- Synapses — Units of output generation. Every token the model generates in its response consumes synapses.
Read the full explanation in Synapses and Neurons.
| Metric | Rate |
|---|---|
| Neurons (input processing) | 8.00 CHF per 1 million neurons |
| Synapses (output generation) | Varies by model |
Pricing is billed in CHF (Swiss Francs). Your dashboard shows consumption in real time.
Different models have different synapse costs:
| Model | Relative Cost | Notes |
|---|---|---|
gpt-4o | Standard | Balanced cost/performance |
gpt-4o | Lower | Optimized for throughput |
gpt-4o | Higher | Advanced capabilities |
| OpenAI, Anthropic, Google models | Varies | Depends on provider pricing |
Contact your account manager or check Freddy for exact per-model rates applicable to your plan.
Use max_output_synapses to cap how many synapses a single response can consume:
{
"organization_id": "org_your_org_id",
"model": "gpt-4o",
"max_output_synapses": 512,
"inputs": [{"role": "user", "content": "Summarize this briefly."}]
}Common limits:
512— Short answers, single-sentence replies1024— Paragraph-length responses4096— Detailed explanations8192— Long documents, code files
Threads carry conversation history. Longer threads consume more neurons per request. Use context_mode on the request to control how much history is included. See Thread Context Modes.
For simple queries (classification, short answers), gpt-4o or gpt-4o-mini consume fewer resources than gpt-4o.
Track your consumption in real time:
- Freddy → Organization → Usage
- Analytics API — Programmatic access to usage data by time range, model, and assistant
See Usage Limits Guide for setting spending limits and alerts.
New organizations receive a trial allocation of synapses and neurons. Check your Freddy dashboard for your current trial balance.
