Reka: Flash 3
Analysis Summary
Reka Flash 3 is a compact model from Reka AI with function calling and a 65K token context window. Its intelligence index of 4.1 is low relative to the broader field, and benchmark scores across reasoning, coding, and instruction following are below competitive mid-tier models.
The livecodebench score of 0.435 suggests some coding capability, and math performance is moderate. However, instruction-following scores are weak, which limits reliability for structured business outputs. There is no vision or tool use support beyond function calling.
At $0.10 input and $0.20 output, it is priced for high-volume, low-complexity tasks. Teams needing a cheap function-calling model for simple automation may find it adequate, but for anything requiring reliable reasoning or content quality, stronger alternatives exist at similar price points.

Editorial notes
