- Fireworks unveils Ultra-fast inference, Background Mode, and Nexus Desktop at Forge
At its first Forge conference, Fireworks announced products aimed at specialized open-model deployments: Ultra-fast serverless inference in public preview on NVIDIA Blackwell (up to about 1,500 tokens/sec on DeepSeek V4.1 Flash, with a cited 30-turn agent task falling from about 1 minute to 8 seconds), Background Mode at half price for deferrable work, multi-day prompt caching, higher rate limits, and Fireworks Nexus Desktop alongside the Nexus CLI so open and closed models can run inside tools such as the Codex app, Claude Desktop, and OpenCode with spend visibility. Pro plans start at $8/month and Teams at $10/seat; Enterprise adds SSO, governance, shared budgets, and access controls. The post also cites Ember-1 token-efficiency results versus Kimi K3.
