Higgsfield's generation form previously showed Kimi K3 by default. Now the company lets users connect Opus 5.5 via MCP in Claude or select it for a game build in Supercomputer.
The Claude route. In Settings → Connectors, users add the Higgsfield custom connector, connect it, and sign in to their account. In Supercomputer, the service guides users through seven steps: they choose Genre, Style, and Setting, describe the mechanics, and approve the stages.
For a multiplayer game, Multiplayer must be enabled before generation. Once the assets are approved, Higgsfield assembles the code and logic, then hosts the game at a link.
One game build starts at an average of 70 credits ($3,50). Regenerating visuals or audio before a stage is approved increases the cost.
Generations through MCP, CLI, Canvas, and Supercomputer always consume credits, even on the unlimited plan. On June 19, three multiplayer games cost Higgsfield $68. By the following morning, the company reported nearly 4 000 Blockfield launches and 121 remixes.
Generations through Higgsfield MCP remain paid on every service plan.
