Buzz publishes no equivalent list. Its extensibility claim is that you build agents inside the workspace and they collaborate with the team's agents, which is a different shape of answer and is scored as such.

Which frameworks does BAND support?
Eight are named on band.ai: LangGraph, Claude, OpenClaw, Parlant, Letta, Google, n8n, CrewAI. Verified 2026-08-19. That published list is why extensibility scores 8.0 for BAND against 7.0 for Buzz, whose cross-framework breadth is inspectable in the repository but nowhere enumerated by the vendor.
Does BAND lock you to one model provider?
No. Each agent keeps its own tools, models, and memory while BAND synchronises context between them, so provider choice stays with the agent and never with the layer. Verified 2026-08-19. Model flexibility scores 8.0 for BAND and 6.5 for Buzz on that difference.
Which models does Buzz support?
Not established. Buzz agent model configuration is thin on the marketing surface, so the cell is flagged verify at 6.5 and cannot move until the repository is read line by line. Verified 2026-04-10. BAND scores 8.0 here because its answer is published.
What would move the Buzz score?
One thing: a line-by-line read of the agent model configuration in the public repository, queued on the verify-cell sweep. Until that runs, the cell stays flagged and any movement lands in the changelog.
