I’ve been extraordinarily productive with this, their $10 Go plan, and a rigorous spec-driven workflow. Haven’t touched Claude in 2 months. I sprinkle in some billed API usage to power my task-planner and reviewer subagents (both use GPT 5.4 now). The ability to switch models is very useful and a great learning experience. GLM, Kimi and their free models surprised me. Not the best, not perfect, but still very product…

The moat is having researchers that can produce frontier models. When OpenCode starts building frontier models, then I'd be worried; otherwise they're just another wrapper

"OpenCode Go" (a subscription) lets you use lots of hosted open-weights frontier AI models, such as GLM-5 (currently right up there in the frontier model leaderboards) for $10 per month.

OpenCode was the first open source agent I used, and my main workhorse after experimenting briefly with Claude Code and realizing the potential of agentic coding. Due to that, and because it's a popular an open source alternative, I want to be able to recommend it and be enthusiastic about it. The problem for me is that the development practices of the people that are working on it are suboptimal at best; they're con…

I am more concerned about their, umm, gallant approach to security. Not only that OpenCode is permissive by default in what it is allowed to do, but that it apparently tries to pull its config from the web (provider-based URL) by default [1]. There is also this open GitHub issue [2], which I find quite concerning (worst case, it's an RCE vulnerability). [1] https://opencode.ai/docs/config/#precedence-order [2] https:…

Openclaw has 20k commits, almost 700k lines of code, and it is only four months old. I feel confident that that sort of code base would have a no coherent architecture at all, and also that no human has a good mental model of how the various subsystems interact. I’m sure we’ll all learn a lot from these early days of agentic coding.

So far what I am learning (from watching all of this) is that our constant claims that quality and security matter seem to not be true on average. Depressingly.

Stupid question, but are there models worth using that specialize in a particular programming language? For instance, I'd love to be able to run a local model on my GPU that is specific to C/C++ or Python. If such a thing exists, is it worth it vs one of the cloud-based frontier models? I'm guessing that a model which only covers a single language might be more compact and efficient vs a model trained across many lan…

I'm currently experimenting with (trying to) fine tune Qwen3.5 to make it better at a given language (Nim in this case); but I am quite bad at this, and honestly am unsure if it's even really fully feasible at the scale I have access to. Certainly been fun so far though, and I have a little Asus GX10 box on the way to experiment some more!

This replaced Aider for me a couple months back. I use it with Qwen 3.5 running locally when my daily limits run out on my other subscriptions. The harness is great. Local models are just slow enough that the subscription models are easier to use. For most of my tasks these days, the model's capability is sufficient; it is just not as snappy.

One thing I like with Aider is the fact that I can control the context by using /add explicitly on a subset of files. Can you achieve the same wit OpenCode ?

Tbf, this seems exactly like Claude Code, they are releasing about one new version per day, sometimes even multiple per day. It’s a bit annoying constantly getting those messages saying to upgrade cc to the latest version

I tried crush when it first came out - the vibes were fun but it didn’t seem to be particularly good even vs aider. Is it better now?

Disclaimer: I work for Charm, so my opinion may be biased. But we did a lot of work on improving the experience, both on UX, performance, and the actual reliability of the agent itself. I would suggest you to give it a try.

Will do thanks - any standout features or clever things for me to look out for?
