DeepSeek-V4-Flash (High) by @deepseek_ai has reshaped the cost-performance Pareto frontier in Agent Arena, with a $0.024 median cost per task! It lands to the right of GPT-5.6 Luna (xHigh) which has a $0.026 median cost per task, and to the left of DeepSeek-V4-Pro (Thinking) at $0.020. It's the model that delivers a positive net improvement at the lowest price point on the chart. Price per task is based on real-world Agent Mode usage. We calculate each task’s cost from tokens consumed and the model’s pricing, including cache hits and misses. Arena.ai @arena DeepSeek-V4-Flash-20260731 (High) by @deepseek_ai landed in Agent Arena at #21 overall (+1.98% net-improvement), and among open source #3 based on +12.5K real-world agentic sessions. This release is ranked 6 higher than DeepSeek-V4-Pro (-0.47%) and 13 higher than the previous DeepSeek-V4-Flash model (-2.81%). Across key signals, DeepSeek-V4-Flash-20260731 (High) is strong in Confirmed Success (+6.99%), but weaker in Steerability (-2.31%). Below we break down how it scored across all 5 signals, drawn from tasks submitted by a global community of users. Here’s an overview on the signals: - Confirmed Success: an explicit "yes that worked" feedback from the user - Praise vs. Complaint: implicit sentiment in users reactions - Steerability: can the model course-correct when you push back? - Bash Recovery: how it recovers from CLI errors (primary signal for tool use) - Tool Hallucination: does it call tools that don't exist 🔗 View Quoted Tweet 💬 5 🔄 4 ❤️ 56 👀 6225 📊 9 ⚡
