- GPT-5.6 Sol is OpenAI's flagship model in the GPT-5.6 series, designed for complex reasoning, coding, and agentic workflows including command-line and multi-step coding tasks
- OpenAI lists GPT-5.6 Sol at $2.50 per 1M input tokens and $15 per 1M output tokens, paired with a 1M-token context window
- GPT-5.6 Sol was released on July 9, 2026, with a knowledge cutoff of February 2026
- The model posts 65 tokens/second P50 throughput and 3.33-second P50 latency on the best-performing provider per OpenRouter monitoring
- OpenRouter tracking shows 100% uptime and 99.83% availability, with automatic failover to healthy upstream providers when errors occur
Why it matters: GPT-5.6 Sol's $2.50/$15 per-million-token pricing combined with a 1M context window and 65 tok/s throughput directly targets enterprise coding and long-horizon agentic workloads, where long context and low per-token cost typically drive provider selection.
