I don't know if I'm doing something wrong, but every time I ask gemini 2.5 for code it outputs SO MANY comments. An exaggerated amount of comments. Sections comments, step comments, block comments, inline comments, all the gang.

I have the same issue plus unnecessary refactorings (that break functionality). it doesn't matter if I write a whole paragraph in the chat or the prompt explaining I don't want it to change anything else apart from what is required to fulfill my very specific request. It will just go rogue and massacre the entirety of the file.

I have the exactly same issue using it with Aider.

This has also been my biggest gripe with Gemini 2.5 Pro. While it is fantastic at one-shotting major new features, when wanting to make smaller iterative changes, it always does big refactors at the same time. I haven't found a way to change that behavior through changes in my prompts.

Claude 3.7 Sonnet is much more restrained and does smaller changes.

Is there anything like Claude code for other models such as gemini?

I'm literally working on this particular problem. Locally-run server; browser-based interface instead of TUI/CLI; connects to all the major model APIs; many, many quality of life and feature improvements over other tools that hook into your browser. Drop me a line (see profile) if you're interested in beta testing it when it's out.

I'm actually very happy with everything in Claude code, eg the CLI so im really just curious to try other models

I've been switching between this and GPT-4o at work, and Gemini is really verbose. But I've been primarily using it. I'm confused though, the model available in copilot says Gemini 2.5 Pro (Preview), and I've had it for a few weeks. This was just released today. Is this an updated preview? If so, the blog/naming is confusing.

My frustration with using these models for programming in the past has largely been around their tendency to hallucinate APIs that simply don't exist. The Gemini 2.5 models, both pro and flash, seem significantly less susceptible to this than any other model I've tried. There are still significant limitations, no amount of prompting will get current models to approach abstraction and architecture the way a person doe…

I have been asking if AI without hallucination, coding or not is possible but so far with no real concrete answer.

Try dropping the entire api docs in the context. If it’s verbose, i usually pull only a subset of pages.

Usually I’m using a minimum of 200k tokens to start with gemini 2.5.

So, are people using these tools without the org they work for knowing? The amount of hoops I would have to jump through to get either of the smaller companies I have worked for since the AI boom to let me use a tool like this would make it absolutely not worth the effort. I'm assuming large companies are mandating it, but ultimately the work that these LLMs seem poised for would benefit smaller companies most and I…

I work for a large company and everything other than MS Copilot is blocked aggressively at the DNS/cert level. Tried Deepseek when it came out and they already had it blocked. All .ai TLDs are blocked as well. If you're not in tech, there is a lot of "security" fear around AI.

Hasn't Gemini 2.5 Pro been out for a while?

At first I was very impressed with it's coding abilities, switching off of Claud for it but recently I've been using GPT o3 which I find is much more concise and generally better at problem solving when you hit an error.

My guess is that they've done a lot of tuning to improve diff based code editing. Gemini 2.5 is fantastic at agentic work, but it still is pretty rough around the edges in terms of generating perfectly matching diffs to edit code. It's probably one of the very few issues with the model. Luckily, aider tracks this.

They measure the old gemini 2.5 generating proper diffs 92% of the time. I bet this goes up to ~95-98% https://aider.chat/docs/leaderboards/

Question for the google peeps who monitor these threads: Is gemini-2.5-pro-exp (free tier) updated as well, or will it go away?

Also, in the blog post, it says:

  > The previous iteration (03-25) now points to the most recent version (05-06), so no action is required to use the improved model, and it continues to be available at the same price.
Does this mean gemini-2.5-pro-preview-03-25 now uses 05-06? Does the same apply to gemini-2.5-pro-exp-03-25?

update: I just tried updating the date in the exp model (gemini-2.5-pro-exp-05-06) and that doesnt work.

If you can get them to approve GitHub Copilot Business then Gemini Pro 2.5 and many others are available there. They have guarantees that they don't share/store prompts or code and the parent company is Microsoft. If you can argue that they will save money (on saved developer time), what would be their argument against?
