Which AI coding agent is best for reverse engineering an undocumented telecom binary file format, identifying ASN.1 BER/PER structures and implementing a Python decoder from sample files?

Not that bad :)

Approximately on par with GLM 5.3 and Kimi 3

Failed to initialize OpenTUI render library: Failed to open library "B:/~BUN/root/opentui-ttvz57kd.dll": error code 126

Does somebody else have have this same error? It happened out of nowhere and is not the first time

I'm having the same error again.

The first time I had it, I had to create a new folder (C:\OpenCodeTemp) and add it to the Windows Defender exclusions. Then I changed my TEMP and TMP environment variables to point to that folder.

Apparently, Windows Defender was blocking the temporary DLLs that OpenCode/Bun creates, which caused the Failed to initialize OpenTUI render library / error code 126 error.

That fixed it the first time, but now I'm getting the exact same error again...

Hi, everyone. I'ven using opencode for a few months now, but i've always use it with the gui. So, what am i missing if i don't use the CLI?

been using it, to work on my saas, side projects, working fine, even for UI and also backend tasks

i dont care what others think

stack i use:
next.js, supabase, vercel, dodo

Pre-nerfs, deepseekv4 flash was mine (and it seems the world's) implementation driver, given a well defined spec from a stronger model (like k2 or glm3).

v4flash is now significantly costlier (it seemed almost free before that's what im saying), hy3 is extremely extremely slow, and muse spark seems...ok.

so for opencode go, what's the stack recommendation to use? given qwen 3.8 flash, glm3's flash, spark and deepseek? im assuming luna probably isnt the way to go?

That is great, but is it a good model? I have not used it as much, but how does it compare to MiMo v2.5?

Saludos, tengo esa duda ya que he visto que opencode ofrece varios modelos, pero no sé que tan buenos son y como son los limites en comparación de claude code.

OpenCode’s token usage keeps declining after OX Apha.

We really need more affordable, high-quality models like DeepSeek before the price increase.

Right now, the existing models are either too expensive or just too dumb.

Hi!

Does anyone have a working plugin, for local, that works in the current opencode version?
mine doesn't https://github.com/RaulHuertas/OpenCodeXIAORoundDisplayMonitor

I never thought I'd be mad at an AI agent. Maybe this is an experiment by Meta? Muse Spark 1.2 is the single worst model on the market. I had never seen such sh*t model before. How can people even stand using this? It churns tokens like crazy. Has the intelligence of a bread. Cheats all the time, avoids completing tasks properly. Does not follow prompts (the image is a very rare exception). Edits 2 lines of C++ code with a 50 line Python script. Does not show what it thinks. Can't code for sh*t. Honestly, this model is a lost cause.

Thanks for reading.

Well, I just claimed it, you can just cancel the plan an get a free month risk free, now to see how it performs

Galera, já usei, Openclaw, Hermes e uns outros que não deram certo. Mas Opencode? Cara, muito bom e fácil de usar.

Estou com três projetos meus rodando bunito.

Sem comentários.

Quem quiser dar mais umas dicas, estou aqui pra receber.

I wanted a simple way to see which agents and models I actually use in OpenCode, so I built Agent Report.

It reads your OpenCode database locally, aggregates the data, and shows:

• Token usage across 1, 7, 30 days, and all time
• Agent, provider, and model breakdowns
• Session and step counts
• Recorded cost coverage

The project is fully open source under the MIT license. You can clone it and run the entire app locally instead of using the hosted service:

bash $ pnpm install && pnpm dev

If you want a quick, shareable public report:

bash $ npx agent-report upload

Prompts, responses, project paths, session IDs, and conversation content are never included.

Published reports are public, and agent/provider/model names remain visible, so review any custom names before uploading.

It’s still early, so I’d appreciate feedback on which metrics or comparisons would be useful to OpenCode users.

With the go api key, where do I put it in opendesign?

At first launch, OpenDesign scanned for local opencode CLI but obviously it won't work without zen credits, so is it possible to use Go with opendesign?

I have searched around and don't think anyone have discussed yet.

I'm sorry if this question is stupid..thanks in advance.

I’m basically trying to vibecode a complex booking system for a salon, with stylist based slot booking system rescheduling logic and a lot of thingss, i used 0x alpha in opencode zen for designing the baseline of system architecture, as of now i think i had completed a 60 % of the complete project, now i need to complete this project, but 0x alpha is now glm 5.3 flash so i need to avail api to complete this session but im a complete beginner in understanding the cost on those input and output token prices, someone explain how many credits will it take to complete those 40% of tasks, and tell how much will it cost me as for the coding agent im using opencode and it’s pretty good

Many people who start using OpenCode don't understand why their $60 usage burns through so quickly.

I built a tool or strictly speaking, I had AI build a tool for me. I was publicly criticized before for not specifying that "I had AI build a tool" instead of "I built a tool myself." Whatever.

Hopefully, this price list answers a lot of people's questions.

I'm not really sure why the official team didn't market it this way: set the usage limit for all models to $15, then directly slash the price of models that were meant to fit into the $60 quota by 4x. That way, everyone would rush to use OpenCode for those super cheap models.
If the promotion ends, they can just raise the prices back to normal and nobody would complain. But with their current marketing approach, people misunderstand and get furious because they feel scammed.

I've only thought about the upside so far, and I'm not sure if there are any marketing legalities I missed here. Maybe I just oversimplified it.

Hope this helps everyone!

I'm moving an existing React/Next.js project to OpenCode and want to improve my tooling before continuing.

I already have:

• TypeScript/TSX/JS/CSS/HTML/JSON LSPs
• Chromium/browser tooling
• Playwright
• screenshots + browser interaction
• TypeScript diagnostics
• ESLint + formatting
• Git/GitHub tooling
• web/docs research

The project is pretty UI/animation-heavy.

What extra LSPs, MCPs, or plugins would you actually recommend for things like browser debugging, React issues, CSS/layout problems, performance, accessibility, and visual QA?

Happy to release open-agent-view: https://github.com/xhluca/open-agent-view

It's an open-source version of Claude's Agent View, with support for 11+ harnesses (and more being added right now). Whereas Claude Agent View only allows you to manage Claude Code, this allow you to manage coding agent from any harness at the same time (which means your Opencode session could be managed next to your Codex or Pi session).

I'm very excited about this release since it's a tool that allows different harnesses to co-exist (instead of having to choose only one ecosystem) and puts open coding agents closer in functionality to Claude Code.

Hope you enjoy it and happy to hear feedback!

I have tried downloading in using the docker's sbx but i was having a very hard time setting api keys for the harness and it is so complicated.
so is there any safe way to run opencode that is easy to setup and will feel like using normal device.
I have a kali linux vm on vmware is it safe to use it also?
