What is the ROI on GPT-5.6 Sol?

Pipelines processing 100M+ tokens per month typically save over $1,200 monthly against a Curtly subscription.

Is any training performed on my GPT-5.6 Sol data?

Never. Curtly has a strict zero-storage architecture. Data is processed in volatile memory and never retained.

Why GPT-5.6 Sol generates high API invoices

GPT-5.6 Sol is built for high-demand enterprise pipelines, but $4.00/1M input and $20.00/1M output costs accumulate rapidly across millions of automated requests. Uncompressed conversation histories and long responses burden your operating margins.

5x output cost premium

Output generation at $20.00/1M is the primary cost driver for customer-facing support bots and autonomous code assistants.

Multi-turn message accumulation

Context windows grow linearly as user chats progress, repeatedly re-submitting early messages at full token rates.

Boilerplate system instructions

Detailed enterprise guardrails and guidelines add hundreds of static tokens to every single API call.

o200k_base tokenizer efficiency

Efficiency rating: 200k vocabulary, highly efficient on English

OpenAI 200,000 token vocabulary provides high compression on English and code, but static system prompts still incur repetitive costs.

How Curtly optimizes GPT-5.6 Sol workflows

Conversation history compaction

Intelligently compresses earlier turns in chat histories while preserving recent conversational context and entities.

Brevity directive injection

Strips filler answers and repetitive summaries at the output stage, saving 35-45% on generation tokens.

Safe Vault protection

Locks JSON keys, UUIDs, URLs, and code snippets completely intact.
