> GPT-6.1 Terra for text, reasoning and function tools through streamed native Responses. This listing supports complete client-supplied conversation history.

- Canonical page: https://chinaapi.ai/models/gpt-6.1-terra/
- Model ID: `gpt-6.1-terra`
- Context window: 1.05M
- Modalities: Text
- Pricing: $2/M input, $7.5/M output tokens (USD)
- Endpoint: OpenAI-compatible `POST https://api.chinaapi.ai/v1/responses`
- Paid price after first top-up: $1.1/M input, $4.125/M output tokens (−45%); one top-up of any amount moves the whole account to Paid prices
- Tier — Over 272K input tokens: Standard $2/M input, $7.5/M output tokens; Paid after first top-up $1.1/M input, $4.125/M output tokens (−45%)
- Tier — Up to 272K input tokens: Standard $1/M input, $5/M output tokens; Paid after first top-up $0.55/M input, $2.75/M output tokens (−45%)
- Price note: Above 272000 input tokens, the entire request uses the long-context tier: input and cache rates are 2x, output 1.5x. Paid input/output/cache-read rates are 55% of Standard; cache-write remains 100%. The quoted Enterprise GPT schedule is 50% for input/output/cache read and 55% for cache write, subject to an active contract; a top-up alone does not activate Enterprise.
- Pricing basis: Standard model rates follow providers' international list prices at 100%; some models have a separate Paid rate after the first top-up.

## Quickstart

```
curl -N https://api.chinaapi.ai/v1/responses \
  -H "Authorization: Bearer $CHINAAPI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-6.1-terra",
    "stream": true,
    "store": false,
    "reasoning": {"effort": "none"},
    "include": ["reasoning.encrypted_content"],
    "input": "Reply with a short hello."
  }'
```

Read the stream through response.completed and use its output and usage. For another turn, append every original output item and the next user message to input. For a function tool, send function_call_output with the original call_id, then submit the full input again. Use store:false; previous_response_id continuation is unavailable. Suppliers may exceed max_output_tokens, so monitor actual usage and set account quotas. Cache discounts apply only to reported cache hits; a hit is not guaranteed.
