When to Use Copilot

✅ Choose Copilot if:

  1. You have a GitHub Copilot subscription

    • Already paying $10-39/month
    • No additional costs for API usage
    • Predictable monthly billing

  2. You need tool support (MCP)

    • Web search, code execution, file operations
    • Real-time data access
    • External API integrations

  3. You want streaming responses

    • Real-time feedback as the model generates
    • Better UX for long-running workflows
    • Progress visibility

  4. You prefer enterprise support

    • GitHub Enterprise integration
    • SSO and access controls
    • Enterprise SLA and support

  5. You need smaller context windows (cost optimization)

    • GPT-4: 8K context (cheaper)
    • GPT-4 Turbo: 128K context (when needed)
    • Pay only for subscription, not per token

Example Copilot Workflow

workflow:
  name: copilot-workflow
  runtime:
    provider: copilot
    default_model: gpt-5.2
    mcp_servers:
      web-search:
        command: npx
        args: ["-y", "open-websearch@latest"]
        tools: ["*"]

agents:
  - name: researcher
    tools: [web_search]
    prompt: "Research {{ topic }} using web search"

When to Use Claude

✅ Choose Claude if:

  1. You need a large context window

    • 200K tokens (all models)
    • Process long documents, code, transcripts
    • Multi-agent workflows with extensive context

  2. You want fine-grained cost control

    • Pay only for what you use
    • Scale to zero when idle
    • Optimize costs with model selection (Haiku vs Opus)

  3. You value output quality for reasoning tasks

    • Claude excels at analysis, synthesis, reasoning
    • More verbose explanations
    • Better at following complex instructions

  4. You run low-volume or intermittent workflows

    • Pay-per-use cheaper than subscription
    • No minimum monthly cost
    • Scale up/down as needed

  5. You want to avoid vendor lock-in

    • Anthropic API works with multiple tools
    • Easier migration between platforms
    • Future-proof for multi-provider strategies

Example Claude Workflow

workflow:
  name: claude-workflow
  runtime:
    provider: claude
    default_model: claude-sonnet-4.5
    max_tokens: 4096
    temperature: 0.7

agents:
  - name: analyzer
    prompt: "Analyze the following document ({{ document | length }} chars)"

Cost Comparison

Scenario 1: Light Usage (10 hours/month)

Copilot:

  • Subscription: $10-39/month
  • Total: $10-39/month

Claude:

  • ~100 requests/month
  • ~1000 tokens/request input, ~2000 tokens/request output
  • Sonnet: (0.1M × $3) + (0.2M × $15) = $0.30 + $3.00 = $3.30/month
  • Haiku: (0.1M × $1) + (0.2M × $5) = $0.10 + $1.00 = $1.10/month

Winner: Claude (3-35x cheaper)

Scenario 2: Medium Usage (40 hours/month)

Copilot:

  • Subscription: $10-39/month
  • Total: $10-39/month

Claude:

  • ~500 requests/month
  • ~2000 tokens/request input, ~4000 tokens/request output
  • Sonnet: (1M × $3) + (2M × $15) = $3.00 + $30.00 = $33/month
  • Haiku: (1M × $1) + (2M × $5) = $1.00 + $10.00 = $11/month

Winner: Tie (depends on model choice and subscription tier)

Scenario 3: Heavy Usage (160+ hours/month)

Copilot:

  • Subscription: $10-39/month
  • Total: $10-39/month (flat rate)

Claude:

  • ~2000 requests/month
  • ~3000 tokens/request input, ~5000 tokens/request output
  • Sonnet: (6M × $3) + (10M × $15) = $18 + $150 = $168/month
  • Haiku: (6M × $1) + (10M × $5) = $6 + $50 = $56/month

Winner: Copilot (3-17x cheaper)

Cost Optimization Tips

Copilot:

  • Use the subscription you already have
  • Optimize prompts to reduce latency (not cost)
  • No per-token optimization needed

Claude:

  • Use Haiku for simple tasks (3x cheaper than Sonnet)
  • Limit max_tokens to reduce output costs
  • Use context: mode: explicit to reduce input tokens

Feature Comparison

Context Window

Copilot:

Migration Path

From Copilot to Claude

Minimal changes required:

# Before (Copilot)
workflow:
  runtime:
    provider: copilot
    default_model: gpt-5.2

# After (Claude)
workflow:
  runtime:
    provider: claude
    default_model: claude-sonnet-4.5

See the Migration Guide for detailed instructions.

From Claude to Copilot

Also straightforward:

# Before (Claude)
workflow:
  runtime:
    provider: claude
    default_model: claude-sonnet-4.5
    max_tokens: 4096

# After (Copilot)
workflow:
  runtime:
    provider: copilot
    default_model: gpt-5.2
    # Remove Claude-specific fields

Decision Matrix

Use this matrix to decide:

Your Situation Recommended Provider
Already have Copilot subscription Copilot
Need tools (web search, code exec) Copilot
Need streaming responses Copilot
Heavy usage (>160 hrs/mo) Copilot
Need 200K context window Claude
Light usage (<10 hrs/mo) Claude
Want pay-per-use pricing Claude
Process long documents Claude
Complex reasoning tasks Claude (Opus)
Simple high-volume tasks Claude (Haiku 4.5)

Multi-Provider Strategy

You can use both providers in different workflows:

Use Case Segregation

# Heavy-use, tool-enabled workflows → Copilot
conductor run research-workflow.yaml --provider copilot

# Long-document analysis → Claude
conductor run document-analysis.yaml --provider claude

# High-volume simple tasks → Claude Haiku
conductor run classification.yaml --provider claude

Cost Optimization

  1. Copilot: Production workflows with tools (flat rate)
  2. Claude Haiku: High-volume batch processing (cheap)
  3. Claude Opus: Complex one-off analyses (premium quality)

Redundancy/Fallback

workflow:
  runtime:
    provider: copilot  # Primary
    # If Copilot fails, manually retry with Claude

Summary

Choose Copilot for:

  • ✅ Tool support (MCP)
  • ✅ Streaming responses
  • ✅ Predictable costs (subscription)
  • ✅ Heavy usage
  • ✅ Enterprise features

Choose Claude for:

  • ✅ Large context (200K tokens)
  • ✅ Pay-per-use pricing
  • ✅ Light/intermittent usage
  • ✅ Long document processing
  • ✅ Cost optimization (Haiku)

Bottom line: Both are excellent. Choose based on your usage patterns, budget, and feature requirements. Conductor makes it easy to switch between them or use both strategically.
