Introduction
Complete guide to using GPT-5.2 API for stable traffic and low-cost migration
GPT-5.2 API for stable traffic and low-cost migration
Run GPT-5.2 on PoYo when your application needs a dependable GPT model for routine chat, older prompt sets, and cost-sensitive agent steps. It supports both /v1/chat/completions and /v1/responses.

Key features of GPT-5.2 API
GPT-5.2 is the economical GPT layer for stable workloads, regression testing, and traffic that does not need the newest reasoning tier.
01
Stable GPT layer for existing workloads
Use GPT-5.2 when repeatability against older prompts and evaluation sets matters more than adopting the latest model immediately.
- Migration-friendly behavior
- Good for routine chat
- Useful for regression checks
02
400K context with 128K output
The context window is smaller than GPT-5.4 and GPT-5.5 but still large enough for support histories, knowledge base passages, and bounded coding tasks.
- 400K context window
- 128K maximum output
- Long but bounded prompts
03
Low-friction Chat migration
Existing OpenAI-style chat clients can keep using Chat Completions while teams gradually test Responses support.
- /v1/chat/completions
- /v1/responses
- Same model ID in PoYo
04
Low-cost GPT traffic layer
Keep high-frequency normal requests on GPT-5.2 and reserve GPT-5.4 or GPT-5.5 for tasks that need stronger reasoning.
- Cheaper GPT token spend
- Good for background agent steps
- Clear upgrade path
Best GPT-5.2 API use cases
01
Low-cost chat and KB Q&A
Serve frequent customer or internal questions where stable answers and low unit cost matter most.
02
Code explanation and test drafts
Use GPT-5.2 for routine code summaries, small fixes, test generation, and documentation drafts.
03
Legacy prompt migration
Keep old prompts and evaluation sets on a stable GPT layer before upgrading selected flows.
04
Cost-sensitive agent steps
Run classification, extraction, rewriting, and other background steps before escalating harder tasks.

How to use GPT-5.2 API on PoYo
Step 1: Create a PoYo API key
Open the dashboard, generate an API key, and add credits for chat usage.
Create API Key
Step 2: Pick Chat Completions or Responses
Use /v1/chat/completions for existing OpenAI-compatible chat apps. Use /v1/responses for reasoning controls, tools, and newer response items.
Step 3: Send a requestcurl --request POST \
--url https://api.poyo.ai/v1/responses \
--header 'Authorization: Bearer YOUR_API_KEY' \
--header 'Content-Type: application/json' \
--data '{
"model": "gpt-5.2",
"input": "Design a test plan for a billing migration.",
"reasoning": {"effort": "medium"}
}'

Why use PoYo for GPT-5.2 API access
01
Lower GPT token cost
PoYo lists GPT-5.2 at 87.5 input credits and 700 output credits per 1M tokens for cost-sensitive traffic.
02
Good for migration and regression
Use GPT-5.2 to compare older prompt behavior before moving flows to GPT-5.4 or GPT-5.5.
03
Keeps GPT endpoint compatibility
Run legacy Chat Completions clients and newer Responses experiments from the same PoYo account.
04
Unified monitoring and billing
Track usage and model spend in the same dashboard as your higher-tier GPT models.
