DeepSeek · updated 2026-08-29
DeepSeek's 2026 generation (V4 Pro and the fast V4-Flash) — the price-performance benchmark for open-weight coding models.
DeepSeek V4 is the cheapest serious coding model per-token (Flash variants especially), so light users should simply use DeepSeek's API or OpenRouter. The flat-rate case is heavy daily agent use, where even cheap tokens compound: Standard Compute routes routine steps to V4-class models automatically inside a fixed monthly price.
Honestly: if ALL your work fits DeepSeek quality, per-token DeepSeek is nearly unbeatable on price. Flat-rate wins when you need V4 volume AND frontier quality in the same workflow — that mix is what unbounded per-token bills are made of.
Every OpenAI-compatible agent runs V4 with a base-URL swap. On Standard Compute the router sends the right steps to V4-class models automatically.
