- **Model ID:** `gpt-5.6-luna`
- **Tier:** Fast
- **Context window:** 272K tokens
- **Max output:** 32K tokens
- **Official price (per 1M):** $1 input / $6 output
- **Your price (per 1M):** input $0.4 → $0.3, output $2.4 → $1.8 (60%–70% off)
- **Base URL:** `https://openai.api.apitoken.sale/v1` · **Endpoints:** `POST /v1/responses`, `POST /v1/chat/completions` (Authorization: Bearer)

## Best for

- Classification, extraction and summarization at scale.
- Latency-sensitive chat and routing layers.
- Cheap pre-processing before a Sol or Terra call.

## Notes

- Same reasoning-effort range as the flagship, including max.
- Text and image input, text output. SSE streaming on both Responses and Chat Completions.
- Requests above 272K input tokens bill at OpenAI long-context rates: 2× input and 1.5× output on the whole request.
