What actually differs
- Context window
- GPT-5.6 Sol takes 1.1M against 1.0M — modestly more room in a single request.
- Input price
- DeepSeek V4-Pro-0813 at $0.66/M against $5/M — 7.6× cheaper to feed.
- Output price
- DeepSeek V4-Pro-0813 at $1.98/M against $30/M — 15.2× cheaper to generate. Output dominates the bill on most agentic workloads, where the model writes far more than it reads.
- Weights
- DeepSeek V4-Pro-0813 publishes weights (MIT (open-weight, as reported)); GPT-5.6 Sol is API-only. That decides self-hosting, air-gapped deployment and fine-tuning before any capability question does.
- Recency
- DeepSeek V4-Pro-0813 shipped 35 days after GPT-5.6 Sol (2026-08-13 vs 2026-07-09).
