Provider: openai  
Category: llm  
Model ID: `openai/gpt-6-luna`

GPT-6 Luna is the fast, cost-efficient model in OpenAI's GPT-6 series, positioned below GPT-6 Sol. It is suited for high-volume and latency-sensitive workloads such as chat, classification, and lightweight agentic...

## Specs

- Context length: 1050000 tokens
- Max output: 128000 tokens
- Modalities: file, image, text
- Released: 2026-09-22

## Pricing

- Input: $0.10 per million tokens
- Output: $0.50 per million tokens

## Providers

- **openai** — ctx 1050000, input $0.10/M, output $0.50/M

## Verdict

GPT-6 Luna offers a massive 1M+ token context window at aggressive pricing—$0.10 input makes it the cheapest way to process entire codebases or document collections in a single call. Early access means no public benchmarks yet, so you're trading proven performance data for cost savings and context depth. Reach for this when you need to ingest huge volumes of text cheaply and can tolerate some uncertainty around output quality until the model matures.
