Migration Guide¶

From OpenAI to Anthropic¶

# Before (OpenAI)
response = openai_client.chat.completions.create(
    model="gpt-4",
    messages=[{"role": "user", "content": prompt}]
)

# After (Anthropic)
response = anthropic_client.messages.create(
    model="claude-3-opus-20240229",
    messages=[{"role": "user", "content": prompt}]
)

From Cloud to Local (Ollama)¶

# Before (OpenAI)
response = openai_client.chat.completions.create(
    model="gpt-3.5-turbo",
    messages=[{"role": "user", "content": prompt}]
)

# After (Ollama)
response = ollama_client.chat(
    model="llama2",
    messages=[{"role": "user", "content": prompt}]
)
