Description

If I use opencode with BigPickle it works. If I use it with any Ollama model whether local or cloud, it is not able to see files.
I know that ollama does allow tool calling, and have even programmed it myself, so there must be a bug in opencode that doesn't work with ollama.
On linux.

OpenCode version

1.0.164

Steps to reproduce

  1. Install ollama

  2. ollama run nemotron-3-nano:30b-cloud

  3. edit ~/.opencode/opencode.json and add
    "ollama": {
    "npm": "@ai-sdk/openai-compatible",
    "name": "Ollama (local)",
    "options": {
    "baseURL": "http://localhost:11434/v1"
    },
    "models": {

     		"nemotron-3-nano:30b-cloud":{
 			"name": "nemotron-3-nano-cloud"
 		}

}
run it and have it write a hello world program or look at a hello world program. Can do it. Should be able to.

did you see our docs on ollama? Did you set num_ctx?

They by default give agent like 4k tokens which is unusable for coding

I do not see any docs at all for this project. Most github repo's have a docs directory that contain info.
For example ollama has a docs directory where it says how to set the num_ctx when using the api. https://github.com/ollama/ollama/blob/a013693f804b69f6af00f79623751277147972c5/docs/api.md?plain=1#L403

In anycase, your point about the num_ctx can be solved in the api call. Maybe add a setting in the ollama parameters for context size.

previously they didnt allow setting it in their openai compliant endpoints or in ai sdk provider they maintain, ill have to see if this was fixed there used to be some blockers for this to be done simply

@rekram1-node FYI, I am currently using the vscode chatgpt-copilot extension for local, as opencode is not working locally. Initially, that extension was also broken, but updating the ollama provider to v2, and setting localhost:11434/api got it working. See https://github.com/feiskyer/chatgpt-copilot/pull/642
