DeepSeek V4 Flash Tops OpenRouter, Costs 1% of Rivals

DeepSeek V4 Flash (0731) has quickly topped OpenRouter's usage charts, reportedly consuming over 8 trillion tokens daily. Independent benchmarks show it achieves near-top performance at a fraction of the cost of competitors, shifting the focus from raw intelligence to cost-efficiency in long-horizon tasks. This is seen as a direct challenge to global closed-source pricing.

Confirmed

• Benchmark scores: Per @teortaxesTex relaying WeirdML, DeepSeek v4 Flash (0731) set SOTA records for cost-accuracy with 57.1% and 63.0%, surpassing the recently discounted GPT 5.6 Luna; the evaluator noted scores slightly below expectations but highlighted its agent potential.
• Cost comparison: Artificial Analysis data (via @SirBoboGargle) shows DeepSeek V4 Flash costs $0.03 on complex real-world workloads vs $3.15 for Claude Fable 5, about 1/100th. @ImaginaryDinner2710 also notes it's 100x cheaper than Anthropic Opus 5.
• Vals Index: Per @zephyrz9, DeepSeek V4 Flash (0731) is the first model scoring above 60 on Vals at the lowest price, 35x cheaper than the next best, with the advantage almost entirely from coding ability.
• Usage and migration: @APPSO and @创业邦 report it tops OpenRouter with 8T daily tokens; domestic models' total usage has surpassed US closed-source models for weeks, with many overseas developers migrating production.
• Concrete pricing: @量子位 reports 7 cents per 3D shooter game, 50 cents per CS game, with overseas resellers adding subsidies, even offering 1-cent-level quotes. @FuSheng0306 estimates heavy users spend 30 yuan/week.
• Cost-saving practice: @PrajwalTomar notes developers often use expensive flagship models for all tasks, leading to high bills; integrating DeepSeek V4 Flash, which costs 1/50th of flagship models, balances cost and performance.

Why it matters

• @FuSheng0306 compares the model to the Ford Model T of AI: not necessarily the best performance, but "good enough and affordable for everyone." V4 Flash offers developers a far more economical choice with excellent coding and agent abilities, defining the market's "kill line." When costs drop to a fraction of competitors, the economic model of agent-era long-horizon tasks is redefined—this is no longer just a performance race but a cost-accounting race.
