OpenAI: GPT-6 Luna Pro (batch) vs OpenAI: GPT-6 Sol (batch)

For a sample job of 1 million input tokens and 250,000 output tokens, GPT-6 Luna Pro (batch) costs $0.11 and GPT-6 Sol (batch) costs $2.25, so GPT-6 Luna Pro (batch) is about 20.0 times cheaper for the same work.

Both read up to 1,050,000 tokens at once, roughly 1,575 pages of text.

Across the 20 tasks where they differ, GPT-6 Luna Pro (batch) scores higher on 4 (Code Completion, JSON Extraction, Bulk Data Labeling and others), GPT-6 Sol (batch) on 16 (SQL Generation, Code Review, Code Refactoring and others).

Pick GPT-6 Luna Pro (batch) if you need lower cost; pick GPT-6 Sol (batch) if you need the stronger all-round task scores.

Costs use current list prices per million tokens; page counts assume about 0.75 words per token and 500 words per page.
