## Verdict

GPT Luna Latest offers OpenAI's largest context window at 1.05M tokens with multimodal support at aggressive pricing — $0.10 input makes it the cheapest way to process massive documents with vision capabilities. The trade-off is zero public benchmark data, so performance on reasoning or code tasks remains unproven against peers like Claude or Gemini. Reach for this when you need to ingest entire codebases or document collections with images and cost matters more than validated performance.
