Editorial excerpt
Gemini 3.8 Flash
AI-assisted, editorially reviewed
A low-cost API trial option, with introductory pricing that needs a budget deadline.
Gemini 3.8 Flash is worth testing when API cost is a major constraint. Its published introductory rates are low, but they are scheduled to end after 2026, so build that deadline into any longer-term budget. The independent results use a high-effort configuration. Check the settings, usable output and response time in your actual workflow; the Flash name and a low token price do not by themselves establish speed or low cost per finished task.
Editorial excerpt
GPT-5.6 Terra
AI-assisted, editorially reviewed
A reasonable option if Terra already works for you; compare its output costs with Sol.
If Terra already works well for you, continuity can be a valid reason to keep it. The current billing comparison still deserves attention: its input rate matches GPT-6.1 Sol, while its output rate is higher. Run both on a small sample of your actual workload before deciding whether to stay or switch. Terra has independent reasoning and terminal-coding evidence, but that evidence alone does not establish an advantage for your existing application.
