Prompt Chaining: Build Complex AI Workflows Step by Step

Chain multiple AI prompts together to build sophisticated workflows — research → analyze → draft → review — all automated.

Prompt Engineering Workflows

Beyond Single Prompts

Complex tasks rarely fit in a single prompt. Prompt chaining breaks work into steps where each prompt's output feeds the next — like a pipeline for AI reasoning.

Building a Chain

import vincony

client = vincony.Client(api_key="YOUR_API_KEY")

chain = client.chains.create(
    name="blog_research_pipeline",
    steps=[
        {
            "name": "research",
            "prompt": "Research the topic: {topic}. Find key facts and statistics.",
            "model": "sonar-pro",
            "output_key": "research_data"
        },
        {
            "name": "outline",
            "prompt": "Create a blog outline based on: {research_data}",
            "model": "claude-opus",
            "output_key": "outline"
        },
        {
            "name": "draft",
            "prompt": "Write a 1500-word blog post following: {outline}",
            "model": "gpt-5",
            "output_key": "draft"
        },
        {
            "name": "review",
            "prompt": "Proofread and improve: {draft}",
            "model": "claude-opus",
            "output_key": "final_article"
        }
    ]
)

result = chain.run(topic="AI code review best practices")
print(f"Steps completed: {len(result.steps)}")
print(f"Total tokens: {result.total_tokens}")
print(result.final_article)

Conditional Branching

Add conditions to your chains — if a fact-check fails, route to a correction step. If sentiment is negative, trigger a different response template.

Error Handling & Retries

Built-in retry logic, fallback models, and step-level error handling ensure your chains complete reliably even when individual steps fail.

# Chain with error handling
chain = client.chains.create(
    name="robust_pipeline",
    steps=[...],
    error_handling={
        "retry_count": 3,
        "fallback_model": "gpt-4o",
        "on_failure": "skip_and_continue"
    },
    timeout_seconds=120
)
