5. @SilkDAO_RWA (SilkDAO): DeepSeek-V4-Flash on OpenCode Go has been drastically cut back

Summary observations

  • The price increase was the hottest topic in August: multiple posts focused on cost comparisons after the 0731 price increase, channel alternatives, and subscription strategies

  • Practical consensus: even after the price increase, V4-Flash remains cost-effective because of its high cache-hit rate and low actual task consumption (ch1lam, Lee Penkman)

  • Capability recognition: from hypervisor debugging to Chrome extension reverse engineering, V4 Flash stands out in real engineering tasks

  • Negative feedback: some users believe OpenCode Go allowances have been "cut back," while the value of the older 0424 version has suffered after the price increase
