OpenAI Slashes GPT-5.6 Luna Pricing 80% — Now $0.20/M Input

OpenAI announced major GPT-5.6 pricing changes July 30 — just 21 days after GA:

1. GPT-5.6 Luna → 80% cut: $1/$6 → $0.20/$1.20 per million tokens
2. GPT-5.6 Terra → 20% cut: $2.50/$15 → $2/$12 per million tokens
3. GPT-5.6 Sol → new Fast mode: 2.5x throughput at 2x price ($10/$60), same intelligence

Why this matters:

• Luna is now cheaper than many non-reasoning models from last year, with GPT-5.6-class reasoning


• Sol Fast mode means same answer quality in a fraction of wall-clock time for latency-bound workflows


• The entire GPT-5.6 family is now production-viable for high-volume workloads

Real cost comparison — automated PR review:
| Model | Cost for 50 PRs/day (8K tokens each) |
|---|---|
| GPT-4-class (~$10/M) | ~$120/month |
| GPT-5.6 Luna ($0.20/M) | ~$2.40/month |

Action: Swap gpt-4o → gpt-5.6-luna in your config. Single string change, 98% cost reduction, better reasoning quality.
