Token Economics & Operational Cost Ratio

Pricing per 1M tokens and prompt caching advantages for long-horizon sessions.

Prompt Input Tokens
Celeris-1$0.1 / 1M
Gemini 3.8 Flash$0.15 / 1M

Celeris-1 is 1.5x cheaper on input tokens ($0.1/M vs $0.15/M).

Completion Output Tokens
Celeris-1$0.4 / 1M
Gemini 3.8 Flash$0.6 / 1M

Output generation costs differ by 1.5x.

Context Caching Advantage
Celeris-1$$0.02 / 1M
Gemini 3.8 Flash$$0.0375 / 1M

Prompt caching significantly reduces long-horizon AST parsing costs during multi-turn Swarm pairing sessions.

Swarm Multi-Agent Topology Synergy

How Swarm orchestrates Celeris-1 and Gemini 3.8 Flash in autonomous engineering clusters.

⚡

Optimal Cluster Configuration

Both models sit in Tier 3 (Tier 3: World-Record Throughput Reflex). Excellent peer redundancy or parallel Coder swarm execution.

Tier 3

Celeris-1

Executes instantaneous file discovery and grep tasks in parallel waves.

Worktree Isolation: Completes worktree inspections in milliseconds without blocking concurrent coders.
Tier 3

Gemini 3.8 Flash

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.

Worktree Isolation: Swarms zero-lock worktree architecture allows running 4x or 8x Gemini 3.8 Flash subagents simultaneously without merge conflicts or file contention.

When to Choose Which Model

Practical developer recommendations based on real-world engineering workloads.

Choose Celeris-1 if:

  • ✓World-record 1,492 TPS generation rate
  • ✓Sub-100ms time-to-first-token on modern edge infrastructure
  • ✓Ultra-low latency for interactive developer agent loops
  • ✓Need Finder Subagent specialization inside Swarm.

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.
