No subscription. No monthly fees. Pay only for what you use.
Purchased with real money via Stripe. Required for code generation (Tier 3) — any operation that calls an external LLM provider. Also accepted for graph queries and envelope assembly.
1 LCN = 20 NOK. Minimum purchase: 5 LCN (100 NOK).
Earned through contributions. When your queries add value to the shared pattern graph, you earn SYN. Spent automatically on graph queries and envelopes — internal operations that don’t require an external LLM.
Cannot be purchased. SYN cannot pay for LLM calls.

LCN covers real costs (LLM providers charge us per token). SYN rewards contributions to the shared knowledge graph — your scan/query activity makes the graph better for everyone.
Graph queries and envelopes fall through to LCN. You can always use the service — SYN just gives you a cheaper path for internal operations.
No. Generation calls external LLM providers that charge in fiat, so it requires LCN. SYN is for internal compute operations only.
When your usage contributes patterns to the shared graph (e.g. a structural pattern gets promoted from your private graph to the shared pattern library), you earn SYN. More contribution mechanisms are coming.
No. Pay-as-you-go only. Your LangCoin balance never expires. No recurring charges.
Unused LangCoin is refundable within 30 days of purchase. Contact support for refunds.
