Does Curtly affect response latency?

Curtly runs in-memory with sub-2ms overhead. Because smaller payloads are transmitted to OpenAI, total roundtrip time often improves.

Can Curtly protect email addresses and user data on Terra?

Yes. Safe Vault locks emails, URLs, and variables untouched.

Why GPT-5.6 Terra generates high API invoices

GPT-5.6 Terra is designed as an efficient workhorse model ($2.00/1M in, $12.00/1M out). In high-volume consumer apps, repetitive context and verbose customer replies quickly mount up into substantial monthly invoices.

6x output token multiplier

Output tokens cost 6x more than input tokens ($12.00 vs $2.00). Verbose answers in high-frequency customer support create unnecessary costs.

System prompt accumulation

Complex system prompts containing extensive guidelines and policy text are re-sent with every message turn.

Unpruned conversational context

Historical chat messages accumulate redundant text that can be compressed without losing intent.

OpenAI o200k_base utility profile

Efficiency rating: 200k vocabulary, high English and code density

Large 200,000 vocabulary size that compresses text efficiently. Optimal results achieved when repetitive system instructions are compacted.
