- ✓fast output at 103.73 tokens per second with known intelligence index of 46.5
- ✓strong coding and STEM performance plus effective 1M-token context handling
- ✓balanced generalist use within text-only coding and technical tasks
Choose DeepSeek V4 Flash if you need
- ✓maximum coding specialization with 480B parameters and technical reasoning focus
- ✓large-scale model capacity for complex codebases at 1M-token context
- ✓scenarios where inference compute cost is not a constraint
- ✓pure coding workloads that benefit from explicit specialization over general performance
Verdict
DeepSeek V4 Flash leads on measurable speed, price, and general coding/STEM utility while matching context size, whereas Qwen3 Coder 480B A35B leads only on explicit coding specialization and raw parameter scale. DeepSeek V4 Flash is the clear practical choice for most high-volume workloads given its 10x lower price and known 103.73 t/s output. Qwen3 Coder remains preferable solely when maximum model capacity for pure coding tasks outweighs cost and speed.

Detailed analysis
Pricing
Winner: DeepSeek V4 FlashDeepSeek V4 Flash costs $0.18 per million tokens. Qwen3 Coder 480B A35B costs $1.8 per million tokens, making it ten times more expensive. This gap directly favors DeepSeek for any high-volume usage.
Speed
Winner: DeepSeek V4 FlashDeepSeek V4 Flash reports 103.73 tokens per second output. Qwen3 Coder 480B A35B provides no speed figure but notes high inference compute cost as a limitation. The known fast Flash variant therefore holds the speed advantage.
Coding Capability
Winner: Qwen3 Coder 480B A35BQwen3 Coder 480B A35B is explicitly positioned as a coding-specialized model with 480B parameters and technical reasoning focus. DeepSeek V4 Flash offers strong coding and STEM performance but lacks the same dedicated coding framing and parameter scale.
Context Handling
Winner: TieBoth models support exactly 1048576 tokens of context. DeepSeek V4 Flash highlights effective large-context handling while Qwen3 Coder emphasizes 1M-token codebases, resulting in equivalent context capacity.
