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: ~$0.0340 per call at standard rates
# Input: $2.00/MTok

Cheapest viable option: Claude Sonnet 5 at $0.0300/call (12% less, 96/100 quality).
What drives code review cost
Review is input-heavy in a way generation is not: the diff or file goes in whole, and structured feedback comes back short. That flips the usual optimization: input rate and cache discounts matter more than output rate. Reviewing the same repository repeatedly means the surrounding context is identical call over call, which is exactly the shape prompt caching is designed for.
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 5,000/2,000 token split, output accounts for 71% of the $0.0340 per-call cost.

Standard token rates
| Direction | $/MTok | Tokens per call |
|---|---|---|
| Input | $2.00 | 5,000 |
| 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 $0.009000 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.
