OpenAI Slashes GPT-5.6 Luna Pricing by 80% Mere Weeks After Launch. Well, Actually, the Competition Remains Cheaper.
OpenAI reduced GPT-5.6 Luna output token pricing by 80% and Terra by 20% just 21 days after initial release. DeepSeek V4 Pro still undercuts Luna on output token cost despite the reduction. The source does not specify exact pre- or post-cut dollar figures.
This illustrates the volatility of API pricing in generative AI. You should model costs with scenario planning rather than fixed assumptions. Locking into a single provider without migration pathways is, frankly, negligent architecture.
OpenAI executed the price cuts. DeepSeek remains the lower-cost competitor on this specific metric. Pasquale Pillitteri reported the comparison.
Step 1: Create free accounts at both openai.com and deepseek.com. Step 2: Locate the pricing pages and note the per-million-output-token rates for comparable models. Step 3: Use a simple calculator to compute a hypothetical monthly bill for your word count, observing how a 5x price swing alters your selection.
