Pricing on AIWave (USD per 1M tokens)

Model	Input	Output	Context
DeepSeek V4 Pro	$0.42	$0.84	1M tokens
GPT-4o	$2.50	$10.00	128K tokens

A call costing $1.00 on GPT-4o runs roughly $0.16 on DeepSeek V4 Pro. At production scale, that is a significant difference.

Key Takeaways

DeepSeek V4 Pro wins on:

• Code generation — 92.1 HumanEval, fewer bugs in practice
• Math reasoning — +13.6 on MATH benchmark, better quantitative tasks
• Long context — 1M tokens vs 128K, feed entire repos in one call
• Cost — ~6x cheaper input, ~12x cheaper output

GPT-4o wins on:

• Multimodal capabilities (vision/audio)
• OpenAI ecosystem integration (assistants, fine-tuning, evals)
• Slight MMLU edge (+0.2, negligible in practice)
