Coding Comparison

Claude 3.5 Sonnet Advantages:

• Larger context window (200K vs 128K)
• More accurate code generation
• Better at following specific instructions
• Honest about what it doesn't know

GPT-4o Advantages:

• Faster response times
• Better multimodal (images + code)
• Larger training data
• ChatGPT ecosystem

Writing Quality

Claude tends to produce:

• More natural, human-like prose
• Better structured long-form content
• Fewer cliché phrases

GPT-4 tends to produce:

• More creative variations

For Voice AI Applications

When building voice-enabled applications, both work great with LangVoice:

# Works with either model
from langvoice_sdk import LangVoiceClient

langvoice = LangVoiceClient(api_key="your-key")

# Generate speech from any AI's output
audio = langvoice.generate(
    text=ai_response,
    voice="heart",
    language="american_english"
)

Safety and Alignment

• Claude: Built with Constitutional AI, tends to be more cautious
• GPT-4: RLHF training, occasionally looser guardrails

Pricing Comparison

Model	Input (1M tokens)	Output (1M tokens)
GPT-4o	$5	$15
Claude 3.5 Sonnet	$3	$15
Claude 3 Opus	$15	$75
