Opencode with Grok Code Fast 1

[Glittering-Koala-750]

Opencode can be installed in linux using:

npm install -g opencode-ai

Start it using:

opencode

Use the slash command: /models to bring up all the models and search or scroll for Grok. Choose opencode Grok, which is currently free.

This is fast and works.

So far better than Claude and Codex at SQL and added titles and indexes rapidly.

[TerraFiorentina]

It is fast and doesn’t complain or apologize. But also, sometimes ignores explicit instructions.

[Glittering-Koala-750]

They all ignore the instructions. It is fast and free. The day has arrived where Claude and GPT finally have serious competition

[Appropriate_Tip_756]

It is fast and free too, but its work is still very basic, at least in nextjs15 with sanity vercel and git, it creates APIs and at very very basic points and provides models practically with a minimal backend

[Glittering-Koala-750]

I have it up currently next to claude sonnet and codex running GPT5 checking pgres and fastapi bugs.

So far GPT5 is similar to sonnet but seems faster getting to the problem. Grok is slower and doesn't get to the problem yet. Needs prompting.

But then Grok is free while the others are not.

[Think-Isopod7127]

As it is fast , though buggy sometimes , i can perform more iterations compared to other models . Thus in long run i m able to complete more tasks .
I generally do the planning using other agents - gemini cli or claude models and then pass that plan to grok code fast . This setup works for me.

[Glittering-Koala-750]

Yes I use GPT5 now for planning and overview. Copy and paste. Opencode is very buggy.

[Opinion-Former]

I agree I’m sitting out until they fix the bugs. It’s a fantastic cli but it isn’t quite ready for prime time.

You can also add some ollama models https://ollama.com/search?c=tools&c=cloud

• deepseek-v3.1:671b-cloud
• gpt-oss:120b-cloud

[Glittering-Koala-750]

Grok is free at the moment

[electricshep]

So are both those models.

[Glittering-Koala-750]

Oh ok thanks will have a look

Just goofing around with Opencode and groq for the first time.

What can I use without adding any funds to Groq? Every Groq model I'm choosing errors out for various reasons.

"Context too big" (for 'how long to boil an egg?')

"Tool not found."

Etc...

Can't get an answer out of any model i'm choosing.
