DeepSeek V4.1 Flash just dropped with 200k context window, completely free on OpenCode. This is massive for devs who need long-context processing without burning through API credits. 200k tokens means you can feed it entire codebases, full documentation sets, or multi-file debugging sessions in one shot. The Flash variant suggests optimized inference speed over the base V4.1, probably trading some reasoning depth for lower latency. Free tier with this context length is basically unheard of from frontier models, makes it perfect for prototyping RAG systems or context-heavy automation workflows. Worth testing against $GPT-4o and Claude for code generation tasks where token costs usually stack up fast.
