INT21 claims DeepSeek V4.1 Flash at 1,700+ tok/s on 8×B200
Security vendor INT21 says its agent swarms run a self-built inference engine serving DeepSeek V4.1 Flash at over 1,700 tokens/sec on 8×B200 for faster cyber defense.

Once attackers get inside a network, they can reach other systems in under 30 minutes, and within 27 seconds. Most organizations won’t spot an intrusion in that window, let alone stop it. Defenders need AI agents that are faster than the attackers. That takes ultrafast inference, so each agent reasons faster, and collaborative agent swarms, so many agents chase every lead at once. We've built both. Our agent swarms have built inference engines that run DeepSeek v4.1 Flash at 1,700+ tokens/sec on 8×B200. If you’re defending an enterprise network and need to outpace attackers, INT21 can help. Reach out at info@int21.ai.
