Yep, on subscription plans DS4.1-Flash-1017 feels more or less infinite. I still reach for Astra at the high end of tasks but DS is great for cheap "crawl the entire codebase and find query optimization" type tasks. I also use a lot of K3.1 Pro lately although admittedly it's a lot more expensive.

Also personally I find that the closed tiny models (Haiku, Luna) feel a lot less capable in practice than their benchmark scores indicate relative to DS.

First, OpenCode and Command Code offer you basically 6x-10x usage for some models (not all, though, look at the exact rates per model). That's a very similar model.

Second, while Anthropic subscriptions on paper offer the most generous usage per dollar spent [1], this comes with a few caveats. First, they are the most expensive of all models in cost/task. Second, if you use Claude Code non-interactively (claude -p "..." or SDK/ACP mode), they apparently charge you 70% more usage; you have to use their CLI tool in the terminal to get the full benefit of a subscription. Also, Anthropic has the lowest cache TTL at 5 minutes, which can really hurt for interactive use. Contrast that with OpenAI's default of 30 minutes (and according to a recent post by Tibo, apparently 12 hours for subscriptions, though I haven't verified it myself) or the fact that DeepSeek caches prompts for three days (which is a major reason for their extremely high cache hit rate and how cheap they are in practice), and it doesn't look like THAT great of a deal in comparison anymore. It is of course still good value for money, just not as great as it may look at first glance.

[1] At least before the recent usage bump to OpenAI's Pro plans, though that doesn't seem to include the Plus plan if that is what you are on.
