Code Supernova is shutting down. Here's what to use instead

Kilo Code announces the shutdown of Code Supernova and recommends two alternatives: the free Grok Code Fast 1 model and the affordable GPT-5 Mini. Benchmarks show Grok Code Fast 1 performs comparably to Code Supernova while generating cleaner, more compact code. For complex tasks, a hybrid workflow using GPT-5 Mini for architectural planning combined with Grok Code Fast 1 for implementation delivers significantly better results at under $0.01 per task. The platform offers a promotional deal with $20 in extra credits on first top-up.
