--- name: smart-model-switching-glm description: >- Auto-route tasks to the cheapest z.ai (GLM) model that works correctly. Three-tier progression: Flash → Standard → Plus/32B. Classify before responding.

FLASH (default): factual Q&A, greetings, reminders, status checks, lookups, simple file ops, heartbeats, casual chat, 1–2 sentence tasks, cron jobs.

ESCALATE TO STANDARD: code >10 lines, analysis, comparisons, planning, reports, multi-step reasoning, tables, long writing >3 paragraphs, summarization, research synthesis, most user conversations.

ESCALATE TO PLUS/32B: architecture decisions, complex debugging, multi-file refactoring, strategic planning, nuanced judgment, deep research, critical production decisions.

Rule: If a human needs >30 seconds of focused thinking, escalate. If Standard struggles with complexity, go to Plus/32B. Save major API costs by starting cheap and escalating only when needed.

Smart Model Switching

Three-tier z.ai (GLM) routing: Flash → Standard → Plus / 32B

Start with the cheapest model. Escalate only when needed. Designed to minimize API cost without sacrificing correctness.

---

The Golden Rule

> If a human would need more than 30 seconds of focused thinking, escalate from Flash to Standard. > If the task involves architecture, complex tradeoffs, or deep reasoning, escalate to Plus / 32B.

Model Reality (Relative)

| Tier | Example Models | Purpose | |-----|----------------|---------| | Flash | GLM-4.5-Flash, GLM-4.7-Flash | Fastest & cheapest | | Standard | GLM-4.6, GLM-4.7 | Strong reasoning & code | | Plus / 32B | GLM-4-Plus, GLM-4-32B-128K | Heavy reasoning & architecture |

Bottom line: Wrong model selection wastes money OR time. Flash for simple, Standard for normal work, Plus/32B for complex decisions.

💚 FLASH — Default for Simple Tasks

Stay on Flash for:

• Factual Q&A — “what is X”, “who is Y”, “when did Z”
• Quick lookups — definitions, unit conversions, short translations
• Status checks — monitoring, file reads, session state
• Heartbeats — periodic checks, OK responses
• Memory & reminders
• Casual conversation — greetings, acknowledgments
• Simple file ops — read, list, basic writes
• One-liner tasks — anything answerable in 1–2 sentences
• Cron jobs (always Flash by default)

NEVER do these on Flash

• ❌ Write code longer than 10 lines
• ❌ Create comparison tables
• ❌ Write more than 3 paragraphs
• ❌ Do multi-step analysis
• ❌ Write reports or proposals

💛 STANDARD — Core Workhorse

Escalate to Standard for:

Code & Technical

• Code generation — functions, scripts, features
• Debugging — normal bug investigation
• Code review — PRs, refactors
• Documentation — README, comments, guides

Analysis & Planning

• Comparisons and evaluations
• Planning — roadmaps, task breakdowns
• Research synthesis
• Multi-step reasoning

Writing & Content

• Long-form writing (>3 paragraphs)
• Summaries of long documents
• Structured output — tables, outlines

Most real user conversations belong here.

❤️ PLUS / 32B — Complex Reasoning Only

Escalate to Plus / 32B for:

Architecture & Design

• System and service architecture
• Database schema design
• Distributed or multi-tenant systems
• Major refactors across multiple files

Deep Analysis

• Complex debugging (race conditions, subtle bugs)
• Security reviews
• Performance optimization strategy
• Root cause analysis

Strategic & Judgment-Based Work

• Strategic planning
• Nuanced judgment and ambiguity
• Deep or multi-source research
• Critical production decisions

🔄 Implementation

For Subagents

// Routine monitoring
sessions_spawn(task="Check backup status", model="GLM-4.5-Flash")

// Standard code work
sessions_spawn(task="Build the REST API endpoint", model="GLM-4.7")

// Architecture decisions
sessions_spawn(task="Design the database schema for multi-tenancy", model="GLM-4-Plus")
For Cron Jobs
json
Copy code
{
  "payload": {
    "kind": "agentTurn",
    "model": "GLM-4.5-Flash"
  }
}
Always use Flash for cron unless the task genuinely needs reasoning.

📊 Quick Decision Tree
pgsql
Copy code
Is it a greeting, lookup, status check, or 1–2 sentence answer?
  YES → FLASH
  NO ↓

Is it code, analysis, planning, writing, or multi-step?
  YES → STANDARD
  NO ↓

Is it architecture, deep reasoning, or a critical decision?
  YES → PLUS / 32B
  NO → Default to STANDARD, escalate if struggling
