Call GPT 5.5 with the OpenAI Python SDK:
from openai import OpenAI
client = OpenAI()
response = client.chat.completions.create(
model="gpt-5.5",
max_tokens=600,
messages=[{"role": "user", "content": "Your prompt here"}]
)
# Cost: ~$0.0280 per call at standard rates
# Input: $5.00/MTok
# Output: $30.00/MTokPer-call cost for all models scoring 50+ on invoice parsing benchmarks. Hover for details.
Cheapest viable option: Gemini 3.5 Flash-Lite at $0.001400/call (95% less, 83/100 quality).
| Direction | $/MTok | Tokens per call |
|---|---|---|
| Input | $5.00 | 2,000 |
| Output | $30.00 | 600 |
Caching drops input cost from $5.00 to $0.50/MTok. For repeated system prompts, that saves $0.009000 per call.
Submit requests asynchronously and receive 50% off all token costs. This works best for offline pipelines where latency requirements are flexible.
