## Strengths

- Reasoning effort from none to max, so it can answer without reasoning when speed matters
- Visual reasoning over screenshots, charts and scanned pages
- Knowledge cutoff of 1 June 2026, later than the other GPT-6 models on this rate card
- Function calling and structured outputs

## Typical use cases

- Drafting and editing customer-facing text
- Reading screenshots, forms and charts
- Visual QA checks on interfaces and documents
- Mid-volume assistants that need image input

## Quickstart

A first request with curl. Replace sk-... with your Seedrise key.

```bash
curl https://api.seedrise.ai/v1/chat/completions \
  -H "Authorization: Bearer sk-..." \
  -H "Content-Type: application/json" \
  -d '{"model":"gpt-6.1-terra","messages":[{"role":"user","content":"Hello"}]}'
```

OpenAI SDK, Python:

```python
from openai import OpenAI

client = OpenAI(base_url="https://api.seedrise.ai/v1", api_key="sk-...")

r = client.chat.completions.create(
    model="gpt-6.1-terra",
    messages=[{"role": "user", "content": "Summarise this contract in three bullets."}],
)
print(r.choices[0].message.content)
```
