Token Economics & Operational Cost Ratio
Pricing per 1M tokens and prompt caching advantages for long-horizon sessions.
Muse Glimmer is 1.88x cheaper on input tokens ($0.08/M vs $0.15/M).
Output generation costs differ by 1.88x.
Prompt caching significantly reduces long-horizon AST parsing costs during multi-turn Swarm pairing sessions.
Swarm Multi-Agent Topology Synergy
How Swarm orchestrates Gemini 3.8 Flash and Muse Glimmer in autonomous engineering clusters.
Gemini 3.8 Flash
Recommended: Coder Subagent
Because Gemini 3.8 Flash is 3x faster and 20x cheaper than frontier pro models, it is the ideal engine for parallel Coder and Finder workers running concurrently inside separate Git worktrees.
Muse Glimmer
Recommended: Finder Subagent
Executes lightweight transformation tasks with minimal token consumption.
When to Choose Which Model
Practical developer recommendations based on real-world engineering workloads.
Choose Gemini 3.8 Flash if:
- ✓Rapid throughput with sub-second time-to-first-token
- ✓Unbeatable economics ($0.15/M input, $0.60/M output, $0.0375/M cached read)
- ✓High recall across 1M+ token contexts without hallucinating file locations
- ✓Need Coder Subagent specialization inside Swarm.
Choose Muse Glimmer if:
- ✓190 TPS streaming speed with minimal cost ($0.08/task)
- ✓Clean AST formatting and syntax normalization
- ✓Low memory requirements for parallel subagents
- ✓Need Finder Subagent specialization inside Swarm.
