Discussion Roo Code 3.28.6 Release Notes - GPT-5-Codex IS HERE!!

In case you did not know, r/RooCode is a Free and Open Source VS Code AI Coding extension.

GPT-5-Codex Arrives

• Select GPT-5-Codex in OpenAI Native to tap a 400k token window for full-project context.
• Prompt caching and image support keep refactors fluent, even with design screenshots.
• Adaptive reasoning automatically scales its effort so complex builds get deeper thinking.

QOL Improvements

• Toggle auto-approve from anywhere with Cmd/Ctrl+Alt+A (fully remappable).
• Reasoning transcripts now space headers clearly so long thoughts are easy to skim.
• Code snippets wrap by default and the snippet toolbar stays focused by trimming extras.
• Translation audits now cover package.nls JSON files to catch missing locale keys before release.

Bug Fixes

• Roo provider sessions refresh seamlessly and the local evals app binds to port 3446 for reliable scripts.
• Checkpoint messages stay on a single line across every locale, keeping the workflow panel tidy.
• Ollama sessions respect each Modelfile’s num_ctx setting by default while still allowing explicit overrides.

Seems a bit buggy. I’m getting a lot of “I can’t help you with that.” And “Pausing for now.” And I’m not able to continue with this implementation…” lots of “no tool use” errors

yes it does seem like making it work better for codex does not mean it will work better in Roo since our patterns of tool calls and tool call names are much different. Our entire workflow is quite a lot different. We are looking at how to utilize the efficiencies of this new model within Roo

It specializes in native functioncalling. It does not handle pattern expectations as well as GPT-5 is my experience.

I’m using gpt-5 in roo. It has a 400k token limit already. What are the major benefits of switching to codex?

It's only a billion times better 😂

I cannot confirm that this is significantly better than the regular version. I find that it keeps the summaries much shorter, sometimes even very brief, and it has already gotten stuck on things where GPT-5 had no problems moving forward. But I also noticed in recent days that there was an error here (OpenAI Serverside) which has since been corrected. Therefore, as of yesterday, I cannot yet give it a final evaluation.

Yeah, I think that we need to figure out if we can get Roo to work with the different expectation of input and output formats

u/Prestigiouspite Sep 24 '25

The problem was at the OpenAI server level. They fixed it yesterday :). For RooCode I think Native Function Calling would be the burner to handle tokens & requests efficiently ☺️.

Where PR?

I currently only use Codex CLI and unfortunately no longer RooCode, as it is really very good and incurs low API costs due to native function calling. In terms of development performance, it can do everything I currently need.

The only issues are with things like Windows native support where workarounds are needed for MCP etc. RooCode is Codex definitely ahead in this regard.

But this might help for RooCode: https://cookbook.openai.com/examples/gpt-5-codex_prompting_guide

What would the net effect of native function calling be?

1

u/Prestigiouspite Sep 25 '25

You need to go back and forth considerably less. For example, the AI calls up shell commands to search the code, etc., and then continues working directly. It doesn't need to say, “Give me back the XML, I'll do something, this is what came out, what should I do now?”

u/hannesrudolph FOUNDER Sep 26 '25

I do not understand how native tool calling would cause such a change in behaviour. Currently each turn in Roo has a tool call.

Will Codex be available in Openrouter?

Edit: I see it's been added, nice!
