The problem, IMO, with open-weight models is that you accustom to the capabilities of frontier models too quickly; and downgrading to an open-weight "frontier minus 2" or "frontier minus 3" model is often painful, since they feel way less useful than their newer closed-weights counterpart. To be honest, I don't know any companies using OW models at a large scale for their operations (agents or chat assistants).
I think this is where Deepseek has nailed the mark; DS4.1 Flash is really, really fast, and really, really cheap. If you give it small, structured goals, it completes them crazy quick, at negligible cost. There's different vectors to differentiate along to stay in the conversation.
I've taken to using them as micro-review subagents at development milestones, where a "frontier - 1" model like Opus or Sol launches 10-15 of them on small review tasks that each run for ~10 minutes. Costs about $1 per cycle, and they usually catch something Astra or Fable didn't. Then the orchestrator validates each claim before passing it back to the planning session so we can fold the findings in.
I haven’t used open weight models yet, but this would match my intuition given I haven’t experienced a noticeable increase in code quality this calendar year. If open weight models are already on par with January frontier models that’s already enough for me to automate most of the manual parts of my work (I.e. not “architecting”).
And once frontier models can architect (turn business requirements into engineered systems) then I guess no one needs a job because that’s the digital singularity.

Perhaps they simply don’t advertise it and investors (currently) love companies that spend heavily on frontier models. That said, OW models, especially when combined with RAG, work quite well, and given the current state of the industry, they may be the only sensible way to keep inference costs under control.
Why do you think OAI etc are all up in arms? They hate what’s going on. Most here are delusional.
I work in a very large market cap firm and i’m telling you - more and more managers are pushed to get their teams to use open source and squeeze employees to get the max out of them.
Closed weight models are not usefully ahead of open weight models for coding anymore. "Fable, write a thousand file codebase from this one sentence prompt" is neat and I bet it required a lot of rollout compute to train, but my actual requirements are more detailed.
I don't know about that. The frontier models have all sorts of strange regressions and quirks. They're more "intelligent" but, like hyper-intelligent humans who speak up without any skin in the game, I've found that they have a strong pull to add complexity to anything they touch. Truth is, I don't need frontier-level intelligence to write a CRUD app or debug my config file. The vast majority of software work is basic pattern matching.
Perhaps because they are dumber, they produce better results? IMO an excellent well-tuned harness combined with a "frontier minus x" model produces the highest quality result. DS4.1 and Qwen3.8, far from being a compromise, legit give me better results. For my personal definition of "better".
