Quick start
Call GPT 5.6 Terra with the OpenAI Python SDK:
from openai import OpenAI
client = OpenAI()
response = client.chat.completions.create(
model="gpt-5.6-terra",
max_tokens=2000,
messages=[{"role": "user", "content": "Your prompt here"}]
)
# Cost: ~$0.0250 per call at standard rates
# Input: $2.00/MTok

Cheapest viable option: Claude Sonnet 5 at $0.0210/call (16% less, 87/100 quality).
What drives copywriting cost
Creative generation is output-dominated: a one-line brief produces paragraphs. Output rate is the number to compare, and the gap between tiers widens with length. Brand voice guidelines and examples are resent on every call and never change, which makes them the obvious candidate for caching.
For GPT 5.6 Terra specifically, that means output tokens cost 6.0x more than input, at $12.00 vs $2.00 per MTok. At this use case’s 500/2,000 token split, output accounts for 96% of the $0.0250 per-call cost.

Standard token rates
| Direction | $/MTok | Tokens per call |
|---|---|---|
| Input | $2.00 | 500 |
| Output | $12.00 | 2,000 |
Prompt caching: 90% off input tokens
Caching drops input cost from $2.00 to $0.20/MTok. For repeated system prompts, that saves $0.000900 per call.
Batch API: 50% off all tokens
Submit requests asynchronously and receive 50% off all token costs. This works best for offline pipelines where latency requirements are flexible.

How can I reduce my GPT 5.6 Terra costs for copywriting?
Three strategies lower GPT 5.6 Terra costs for this task type effectively. Prompt caching gives a 90% discount on input tokens when reusing system prompts. The batch API gives 50% off all tokens for asynchronous processing workloads. Prompt optimization reduces token counts through more concise instructions and context windows. Combining caching with batching brings your cost from $0.0250 to about $0.001250 per call.
How does GPT 5.6 Terra pricing compare to other GPT models?
GPT has 4 other models alongside GPT 5.6 Terra today: GPT 5.5 at $5.00/$30.00 per million tokens (flagship), GPT 5.4 at $2.50/$15.00 per million tokens (mid-tier), GPT 5.6 Sol at $4.00/$20.00 per million tokens (flagship), GPT 5.6 Luna at $0.20/$1.20 per million tokens (fast / budget). The right choice depends on whether your copywriting workload prioritizes quality, cost, or speed.
What context window does GPT 5.6 Terra support?
GPT 5.6 Terra supports a context window of 1,050K tokens per API call. This sets the maximum combined length of your input prompt and generated response. For copywriting, typical calls use 500 input and 2,000 output tokens. That is well within this limit, leaving room for longer prompts or multi-turn conversations.
