Can't agree with that. Gemini doesn't lead just on price/performance - ironically it's the best "normie" model most of the time, despite it's lack of popularity with them until very recent. It's bad at agentic stuff, especially coding. Incomparably so compared to Claude and now GPT-5. But if it's just about asking it random stuff, and especially going on for very long in the same conversation - which non-tech users h…

Does it still try to 'unplug' itself if it gets something wrong, or did they RL that out yet?

Not sure if you're joking or serious? Every model has "degenerate" behavior it can be coerced into. Sonnet is even more apologetic on average.

ChatGPT and Claude are mistaken if they think it is incorrect. The parallelism in verb tenses is between "continuing to deliver" and "improving the efficiency". It's a bit wordy, but definitely not wrong.

"Improving the efficiency" sounds fine to me (a native English speaker), what's wrong with it in your opinion?

You would just say "improving efficiency". Whereas theirs is like: "Improving the efficiency [... of what?]"

It's pretty good and fast af. At backend stuff is ~ gpt5-mini in capabilities, writes ok code, and works good with agentic extensions like roo/kilo. My colleagues said it handles frontend creation so-so, but it's so fast that you can "roll" a couple of tries and choose the one you want. Also cheap enough to not really matter.

Yeah, the speed and price are why I use it. I find that any LLM is garbage at writing code unless it gets constant high-entropy feedback (e.g. an MCP tool reporting lint errors, a test, etc.) and the quality of the final code depends a lot more on how well the LLM was guided than the quality of the model. A bad model with good automated tooling and prompts will beat a good model without them, and if your goal is to b…

This is so far off my experience. Grok 4 fast is straight trash, it literally isn’t even close to decent code for what I tried. Meanwhile Sonnet is miles better - but even still, Opus while I guess technically being only slightly better, in practice is so much better that I find it hard to use Sonnet at all.

"the" is redundant is probably what GP means.

Ugh. If the model name includes sem_ver version number, increment the version number when making a new release! Anthropic learned this lesson. Google, Deepseek, Kimi, OpenAI and others keep repeating it. This feels like Gemini_2.5_final_FINAL_FINAL_v2.

2.5 isn't the version number, its the model generation. it would only be updated when the underlying model architecture, training, etc are updated. this release is, as the name implies, the same model but likely with hardware optimizations, system prompt, and fine-tuning tweaks applied.

Ok, so if not 2.6 then 2.5.1 :)

This really captures something I've been experiencing with Gemini lately. The models are genuinely capable when they work properly, but there's this persistent truncation issue that makes them unreliable in practice. I've been running into it consistently, responses that just stop mid-sentence, not because of token limits or content filters, but what appears to be a bug in how the model signals completion. It's been…

chatgpt also has lots of reliability issues

Am I the only one who is starting to feel the Gemini Flash models are better than Pro? Flash is super fast, gets straight to the point. Pro takes ages to even respond, then starts yapping endlessly, usually confuses itself in the process and ends up with a wrong answer.

I tried to put Pro deep research on an actual research task and it didn’t even return anything just kept on working.

Usually you would say "improving the efficiency of x and y". In this case at the end of the sentence it should be "improving the models' efficiency" or just "improving efficiency". I don't think it's "wrong" and it's obviously clear what they mean, but I agree that the phrasing is a little awkward.
