GPT-5.6 vs DeepSeek V4
OpenAI’s GPT-5.6 Sol family commands the enterprise standard. But DeepSeek V4’s open architecture running on unthrottled hosted GPUs is delivering comparable intelligence at blinding speeds. Here is what the telemetry shows.
| Metric / Attribute | 🌐 OpenAI GPT-5.6 | 🚀 DeepSeek V4 |
|---|---|---|
| Standard API Throughput | 45 – 70 tok/s | 90 – 140+ tok/s (Hosted) |
| P95 Latency Spikes | 8 – 15s (Traffic contention) | Consistent (< 2s) |
| Cost per 1M Output Tokens | $15.00 – $30.00 | $0.28 – $0.95 (Fractional) |
| Deployment Freedom | Locked to OpenAI API & Azure | Any Cloud, On-Prem, or Local |
| Rate Limit Risk | Severe TPM / RPM throttling | Unlimited on dedicated compute |
| Best Use Case | Enterprise legacy compliance | High-throughput agentic automation |
DeepSeek V4 Dominates the "Most Attractive" Efficiency Quadrant
Independent tracking by Artificial Analysis demonstrates the staggering compute gap: DeepSeek V4 Flash sits squarely in the green "Most Attractive Quadrant" at roughly ~$0.025 per task, while GPT-5.6 Sol ($1.10/task) charges a massive proprietary premium for comparable downstream performance.
