    DS isn't better than Sol and Gemini in the benchmarks, but after working with them all for a while now I'm beginning to understand why people find DS _feels_ so much better.

    First, it's the tok/s and TTFT from providers. Deepseek blazes through work - at quite good quality - and you don't find yourself waiting for your agents to finish.

    Second is the openness. Being able to see the CoT and not being randomly blocked for cyber review. You're never wondering if it's stuck or if it will randomly fail. Combined with the great cost value.. My next subscription will probably be Z.ai

      Deepseek and Muse are my go to for cheap. both work perfect for basic and mid tier tasks

      Is that a dig on DeepSeek not offering subscription plans?

      If so OpenCode Go looks good and includes DeepSeek models (yet to try myself).

      also it's cheap, using it in opencode is great

    The company's own news page: https://api-docs.deepseek.com/news/news261017

    They are showing this new version scoring significantly higher across multiple coding benchmarks, beating Sol 5.6 (6.1 is the latest) across 10/11 benchmarks.

    I really like the having DeepSeek Flash + Opus 5.5 as advisor/reviewer at the moment. I run through a $200 Claude Code subscription in less than 24 hours now just for a single project, and I hate fiddling with different accounts every day. Now that I get a 200 USD api credits inlcuded with the subscriptions I have rewritten my coding agent workflow completely.

      How?

      • olavgg 32 minutes ago
        Its easy when you spawn a couple of subagents in a homelab with a rack with 5+ servers.

        This is how one of my claude code session looks like right now, one prompt from yesterday:

          Not sure if this will help you but it helped me. I was using subagents and workflows for lots of long running tasks, and part of that work included running tests. If tests took longer than 5 minutes, the cache expired, and the whole thing was then being processed as uncached input.

          I created a skill to better manage agents, including a way to keep the caches valid, and it has decreased my usage considerably. I now struggle to use my 100% each week and I hit claude hard. I have a reset expiring in 5 days and I'm trying to burn down the tokens (68% with 3d 8h left) quickly so I can use my reset before it expires.

          Token efficiency just means understanding the way the system works. Best person to help with that... my old friend claude.

            Some to think about with both Claude and skills.

            Can you invert things. What’s deterministic and what needs “thinking”?

            Can you create a script that runs things chaining together the deterministic parts with calling out to Claude for glue that needs “thinking”.

          • olavgg 19 minutes ago
            Yeah, I should see if I can create a similar skill. The tests do spend some time to complete.

            Claude: Confirmed: 195M of the 212M cache tokens (92%) come from full re-writes after 5+ minute gaps, accounting for 77% of relative cost. Now I'll check the existing wrappers so the skill builds on them.

              Ask Claude, it's pretty wild to see.

        Not OP, but I used to run out in a few days, for me it was a matter of suboptimal code review practices with many subagents looking at different aspects, often expanded to look at more than the diff.

        I can drain a $200 OAI plan in 2 hours flat working on my 10 projects simultaneously.

        Maybe you're not being ambitious enough with these things? They are at their most fun when you spec out sprawling architecture documents and watch 1+8 astras buzzsaw through it.

        I'm only at 260B for the year, though. I'm sure someone who has used more will be along shortly to chime in

        E: The other subthread talking about tests is correct. Expensive models should not waste a single second waiting on tests or validation. If you cannot assign a single cheap model to be the test bitch, then just tell them to frontload everything and clean up later as a single wave.

          Not meant as a bad faith response but have you shipped anything? Do you have income from this? Why 10 projects apart from fueling ADHD and "never finishing a project"?
          • joshstrange 5 minutes ago
            Not OP and while I’m not draining my accounts in a single day/hour, I’m hitting limits with a $200-Claude and $100-OpenAI account.

            > Have you shipping anything?

            Yes, hundreds of PRs and shipped new features to 3 different platforms (day job and 2 side-business apps/platforms I’ve been developing for many years, pre-LLM). Those new features have gone out to customers and been used.

            > Do you have income from this?

            Well my day job for one, and I’ve been able to more easily sell to new clients with my side business. Without the changes I’ve shipped I would have been able to land a couple of the clients I’ve signed on recently.

            I don’t think OP’s message implied they are never finishing a project, maybe they edited it?

            In addition to the 3 income-generating projects, I have a number of other “just for me” projects. Some are mature now and only need occasional development when I want a new feature. Some are in flux as I build them out (like my “software factory”).

            At this point I’m limited by compute and tokens more than anything else.

            Some of us want to build and don't care that it doesn't monetise.

          Would love to see these 10 projects that are being worked on simultaneously
      • ramigb 38 minutes ago
        I swear I have the same question in my head always when I read such statements! I have never once reached 90% that includes everyday usage across multiple repos, artefact generation, device debugging, long running harness work!

        I am not saying OP is not telling the truth. I just really want to understand!

        • pheggs 28 minutes ago
          in my experience there's a huge difference in token usage when creating new projects versus working on existing ones

        not reviewing its ongoing work and spawning subagents that end up looping each other

      Interesting, coming from a similar situation, I'm interested what workflow you landed on. Opus planning + available to be called for deep thinking + opus reviwer? or?

    The native web search api is 10x cheaper than OpenAIs. I hope they will release the web search api as a standalone API.
    • ytxm 41 minutes ago
      I gave it a kick and got mixed results. For example, searching for a Microsoft product couldn't find its landing page, and searching for a niche open source package landed in the Debian repos for the top hits, but the home page was in the first 10 hits.

      Lovely to see they're doing their own search though, I love how many folk are actively working on search clones at the moment.

    • alex-moon 1 hour ago
      I may be missing something so apologies if I'm telling you something you already know but: there are plenty of web search APIs for agents - the Brave one is the one I use: https://brave.com/search/api/

        Tavily one is free, too. Easy to use cli with a skill.

    This and (the not quite yet open) Kimi K2.8 are my main coding engines, and I find them incredibly cost efficient. I find Deepseek in particular is really good with Svelte work.

    Right now I use each of them in their own respective coding harnesses, deepseek-harness and kimi-code, but I do wonder what they are like inside something like opencode.

    Is it already updated to the newest version on Opencode?

    By far my favorite model.

    At the beginning of the month I realized I had more tokens and more capabilities on Opencode at 8$/month via DS 4.1 flash, than I had on a 200$ account in June with the american providers.

    Literally both more tokens and capabilities than Opus 4.8/GPT 5.5.

    Even if you pay per token, you're still unlikely to outspend american providers.

    My favorite model just got better. Gotta love what deepseek is doing
