DeepSeek’s officially released new multimodal visual-understanding model, DeepSeek‑V4‑Flash‑Vision‑Exp, is experimental in nature and supports multimodal inputs. In pure-text capabilities (agents, reasoning, world knowledge, etc.), DeepSeek‑V4‑Flash‑Vision‑Exp is on par with the official DeepSeek‑V4‑Flash release.
DeepSeek V4 Flash Vision Exp vs GLM 5.2
Output tokens cost $0.28 per million on DeepSeek V4 Flash Vision Exp and $3.94 per million on GLM 5.2. Input tokens cost $0.14 per million on DeepSeek V4 Flash Vision Exp and $1.13 per million on GLM 5.2. Cached input tokens are billed at $0.03 per million on DeepSeek V4 Flash Vision Exp and $0.28 per million on GLM 5.2. Context lengths are 1,000,000 tokens on DeepSeek V4 Flash Vision Exp and 1,000,000 tokens on GLM 5.2. Time to first token (TTFT) measured on AIHubMix is 2.4s on DeepSeek V4 Flash Vision Exp and 1.1s on GLM 5.2. Measured output throughput is 70.3 tok/s on DeepSeek V4 Flash Vision Exp and 46.3 tok/s on GLM 5.2.
GLM 5.2GLM-5.2 is Z.ai’s flagship model for the era of long-horizon tasks. With a truly usable 1M-token context window, it can handle project-level engineering context, execute long-running tasks more reliably, follow engineering standards more consistently, and complete the full development workflow from requirements to multi-platform deployment in a single task.
