What to watch — open questions
- Is Muse Spark's reported training-cost discount reflected in API/agent pricing, or is it a research-only benchmark claim?
- Does Muse ship with tool-use/agent-harness capabilities comparable to Claude Code, Codex, or Gemini's agent offerings?
- Is Muse being positioned for developer/API access, or is this launch purely consumer-facing?
