Editorial excerpt
Gemini 3.6 Flash
AI-assisted, editorially reviewed
Google's latest Flash model combines fast multimodal operation with a 1M-token context window and mid-tier token pricing.
Gemini 3.6 Flash combines a 1M-token context window, multimodal input, and exact-variant HLE, SWE-Bench Pro, Terminal-Bench 2.1, and MRCR evidence. At $1.50 per million input tokens and $7.50 per million output tokens, it targets fast general-purpose and agentic workloads rather than maximum frontier capability.
Editorial excerpt
GPT-5.6 Luna
AI-assisted, editorially reviewed
The fastest, lowest-cost GPT-5.6 option for high-volume workloads.
GPT-5.6 Luna is the fastest and lowest-cost tier in the family. Its accepted HLE and SWE-Bench Pro evidence keep it competitive for high-volume workflows, while difficult tasks should still be tested against Terra or Sol.
