After Anthropic's Claude Fable 5 and Mythos 5 were pulled globally due to a US government export control directive just three days after launch, Kilo highlights four alternative frontier models that remain available: GPT-5.5 (top-ranked on KiloBench at 74.2%), NVIDIA Nemotron 3 Ultra (free, open-weight, self-hostable), MiniMax M3 (extremely cost-efficient at $0.30/M input tokens, open weights), and Kimi K2.7 Code (1T-parameter MoE, strong MCP tool-use, open-weight). The post argues that model diversity and infrastructure flexibility are essential for production reliability when any single model can disappear overnight due to regulatory action.
