DeepSeek V4 vs GPT-4o vs Claude 3.7: The New AI Trinity in 2026

The Quiet Revolution

When DeepSeek V4 shipped on April 24, 2026, the Western AI press was characteristically distracted by whatever drama was trending. But the numbers were impossible to ignore: open-source weights, 1M token context, and prices that start at $0.14/M tokens.

This is not a preview. This is the full release — and it changes the game.

The Contenders

DeepSeek V4

• Parameters: 1.6T total (V4-Pro) / 284B total (V4-Flash)
• Context: 1M tokens
• Architecture: MoE + Engram Conditional Memory (O(1) knowledge retrieval)
• Attention: CSA + HCA hybrid — 73% FLOPs reduction vs standard attention
• License: MIT (open weights on HuggingFace)
• Pricing: $0.14/M input, $0.28/M output (Flash); V4-Pro at market competitive rates
• Release date: April 24, 2026

OpenAI GPT-4o

• Parameters: ~1.8T (MoE architecture)
• Context: 128K tokens (1M for GPT-4o with extended)
• Strengths: DALL-E + voice + video (Sora) built-in, largest ecosystem
• Pricing: $5/M input, $15/M output (GPT-4o)
• Best for: Users already in the OpenAI ecosystem who need the broadest feature set

Anthropic Claude 3.7 Sonnet

• Parameters: ~3.7T (effective)
• Context: 200K tokens
• Strengths: Best-in-class coding, 200K context, Extended Thinking mode, Artifacts, MCP connectors
• Pricing: $3/M input, $15/M output (Pro)
• Best for: Developers, researchers, and anyone who needs long-document analysis

Head-to-Head Comparisons

The Engram Memory Architecture

DeepSeek V4's most interesting innovation is the Engram conditional memory module. Instead of treating all knowledge retrieval as a computation problem, Engram separates:

• Factual memory: Stored in O(1) retrievable Engram modules, not computed each time
• Reasoning computation: Focuses compute on actual reasoning, not fact retrieval
• Result: 73% FLOPs reduction in attention layers, faster inference, lower costs

This is a genuinely novel approach that other labs are reportedly racing to replicate.

Coding Benchmark Results

Early第三方测试显示 DeepSeek V4-Pro 在代码生成任务上与 Claude 3.7 Sonnet 接近，部分基准测试甚至超越。在 HumanEval 和 MBPP 上的表现尤其强劲，在长代码库理解和跨文件重构任务上优势明显。

What DeepSeek V4 Cannot Yet Do

• No native image generation: GPT-4o has DALL-E built-in, Claude has Artifacts for code visualization
• No voice mode: SOTA voice interaction is still GPT-4o + Advanced Voice
• Ecosystem: OpenAI and Anthropic have years of tooling lead (Agents, MCP, etc.)
• Long context in practice: 1M token window is theoretical; quality at extreme lengths varies

The Verdict

DeepSeek V4 is the best choice if: You want open-source, maximum context, or are price-sensitive. The coding capability alone makes it worth evaluating.

GPT-4o is the best choice if: You need the broadest feature set (voice, image generation, video) and are already in the ecosystem.

Claude 3.7 is the best choice if: Coding quality is paramount, you need 200K context for documents, or you rely on Anthropic's MCP connectors.

The AI race just got a lot more interesting. DeepSeek V4 does not kill GPT-4o or Claude — it pressure-tests them both and forces the whole industry to be better.
