DeepSeek V4 Flash: DeepSeek's fast agentic coding MoE (284B total, 13B active), served from the official 0731 release on a 1M-token context. The cheapest production model in the lineup for real agentic work. Reasoning has four modes: non-think (none), think low (low, the default), think high (high) and think max (max). Served on our own GPU infrastructure with high availability. Deprecated: use `umans-deepseek-v4.1-flash` instead (sunset 2026-11-01).

Retired: Umans GLM 5.3 Flash, DeepSeek V4 Flash and Qwen3.6 35B A3B Retired
umans-glm-5.3-flash, umans-deepseek-v4-flash-0731 and umans-qwen3.6-35b-a3b reached their sunset and were retired in favour of DeepSeek V4.1 Flash: they leave the catalog and the model pickers, and their history stays on the past-models list. Requests still pinned to the old ids keep routing for a short grace tail; migrate to umans-deepseek-v4.1-flash now (1M context, native vision; umans-coder and umans-flash already run it). A final cutoff date will be announced ahead of the hard stop.

Released pay-per-token: Umans DeepSeek V4 Flash Released
umans-deepseek-v4-flash-0731 joins the lineup as the cheapest way we serve real agentic work: $0.14 / $0.28 / $0.028 per 1M (input / output / cache read), a 1M context window, thinking at low effort by default (dial up high or max when a task deserves more). It is the new default for new chats and CLI setups. Founding users pay the 10x cheaper cache rate until Monday, August 10, 2026 (see /pricing). Served on our own GPU infrastructure with high availability.
