Pros and cons
GPT-5.6 Sol
Chatbots · paid
Pros
- ✓Three-tier family lets you match model cost to task difficulty instead of overpaying
- ✓Claimed state-of-the-art on Terminal-Bench, a meaningful real-world coding/agentic benchmark
- ✓Luna tier ($1/$6 per 1M tokens) is genuinely cheap for a current-generation model
- ✓Strong focus on agentic, long-horizon workflows rather than just chat
Cons
- ×Launched in limited preview — not broadly available, so you can't reliably build production on it yet
- ×Sol's $5/$30 pricing is premium; costs add up fast on token-heavy agentic loops
- ×Cybersecurity/dual-use framing and gov coordination signal tighter usage gating than a normal release
- ×Benchmark claims are vendor-reported at launch; independent verification is still pending
