Expected pricing comparison#

ModelGPT-6 (predicted)Claude 5 (predicted)
Flagship input$2-5 per 1M35per1M(Sonnet)/3-5 per 1M (Sonnet) / 15-20 (Opus)
Flagship output$8-20 per 1M1525(Sonnet)/15-25 (Sonnet) / 75-100 (Opus)
Budget tier$0.03-0.08 (Nano)$0.50-1.00 (Haiku)

Through Crazyrouter, both will likely be available at 40-45% below official pricing.


The smart strategy: prepare for both#

Do not bet on one model. The best approach is model-agnostic infrastructure:

python
from openai import OpenAI

client = OpenAI(
    api_key="your-crazyrouter-key",
    base_url="https://crazyrouter.com/v1"
)

# Test both when available, use the best for each task
CODING_MODEL = "claude-sonnet-4.6"    # → claude-sonnet-5 when available
REASONING_MODEL = "gpt-5.2"          # → gpt-6 when available
CHEAP_MODEL = "gpt-5-nano"           # → gpt-6-nano when available

def code_task(prompt):
    return client.chat.completions.create(
        model=CODING_MODEL,
        messages=[{"role": "user", "content": prompt}]
    ).choices[0].message.content

def reasoning_task(prompt):
    return client.chat.completions.create(
        model=REASONING_MODEL,
        messages=[{"role": "user", "content": prompt}]
    ).choices[0].message.content

When both models launch, benchmark them on your actual workloads and update the config.

FAQ#

Which will be better, GPT-6 or Claude 5?#

It depends on the task. Historically, Claude leads in coding and long-form analysis, while GPT leads in multimodal and general reasoning.

Can I use both through one API?#

Yes. Crazyrouter provides access to both OpenAI and Anthropic models through a single API key.

Should I wait for GPT-6 or Claude 5 before building?#

No. Build now with current models and keep your architecture model-agnostic.

Which will be cheaper?#

GPT-6 Nano will likely be the cheapest option for simple tasks. For complex work, pricing will be comparable.
