> Today, we are releasing updated versions of Gemini 2.5 Flash and 2.5 Flash-Lite, available on Google AI Studio and Vertex AI, aimed at continuing to deliver better quality while also improving the efficiency. Typo in the first sentence? "... improving the efficiency." Gemini 2.5 Pro says this is perfectly good phrasing, whereas ChatGPT and Claude recognize that it's awkward or just incorrect. Hmm...

This is pedantic. It's perfectly fine usage in non-formal English speaking. What's more - who gives a shit? By your own standards, you're inserting a quote in the middle of your comment in an arguably similarly "awkward" way.

Google seems to be the main foundation model provider that's really focusing on the latency/TPS/cost dimensions. Anthropic/OpenAI are really making strides in model intelligence, but underneath some critical threshold of performance, the really long thinking times make workflows feel a lot worse in collaboration-style tools, vs a much snappier but slightly less intelligent model. It's a delicate balance, because thes…

I would be surprised if this dichotomy you're painting holds up to scrutiny. My understanding is Gemini is not far behind on "intelligence", certainly not in a way that leaves obvious doubt over where they will be over the next iteration/model cycles, where I would expect them to at least continue closing the gap. I'd be curious if you have some benchmarks to share that suggest otherwise. Meanwhile, afaik something G…

I do scientific and hard code a lot. Gemini is a good bit below GPT5 in those areas, though still quite good. It's also just a bad agent, it lacks autonomy and isn't RL'd to explore well. Gemini's superpower is being really smart while also having by far the best long context reasoning, use it like an oracle with bundles of your entire codebase (or a subtree if it's too big) to guide agents in implementation.

Seems llm progress really is plateauing. I guess that was to be expected.

And this existing model’s update is evidence how? What were your expectations of this update?

I actually even agree that the progress is plateauing, but your comment is a non-sequitur.

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…

That used to happen a lot in ChatGPT too.

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.

Yeah that's how I feel too. Flash is less verbose and every LLM nowadays seems to be designed by some low-taste people who reward the model for falsely hedging (i.e. "The 2024 Corolla Cross usually has an X gallon gas tank") on stuff that isn't at all variable or questionable. This false hedging is way more of an issue than hallucinations in my experience and the "smarter" 2.5 Pro is not any better at avoiding this issue than Flash

Also 2.5 Pro is often incapable of searching and will hallucinate instead. I don't know why. It will claim it searched and then return some made up results instead. 2.5 Flash is much more consistently capable of searching

Why is Grok so popular

Grok Code Fast 1 usage is driven almost entirely by Kilo Code and Cline: https://openrouter.ai/x-ai/grok-code-fast-1/apps Both apps have offered usage for free for a limited time: https://blog.kilocode.ai/p/grok-code-fast-get-this-frontier-... https://cline.bot/blog/grok-code-fast

Yep Kilo (and Cline/Roo more recently) push these free trial of the week models really hard, partially as incentive to register an account with their cloud offering. I began using Cline and Roo before "cloud" features were even a thing and still haven't bothered to register, but I do play with the free Kilo models when I see them since I'm already signed in (they got me with some kind of register and spend $5 to get $X model credits deal) and hey, it's free (I really don't care about my random personal projects being used for training).

If xAI in particular is in the mood to light cash on fire promoting their new model, you'll see it everywhere during the promo period, so not surprised that heavily boosts xAI stats. The mystery codename models of the week are a bit easier to miss.

Non-AI Summary: Both models have improved intelligence on Artificial Analysis index with lower end-to-end response time. Also 24% to 50% improved output token efficiency (resulting in lower cost). Gemini 2.5 Flash-Lite improvements include better instruction following, reduced verbosity, stronger multimodal & translation capabilities. Gemini 2.5 Flash improvements include better agentic tool use and more token-effici…

2.5 Flash is the first time I've felt AI has become truly useful to me. I was #1 AI hater but now find myself going to the Gemini app instead of Google search. It's just better in every way and no ads. The info it provides is usually always right and it feels like I have the whole generalized and accurate knowledge of the internet at my fingertips in the app. It's more intimate, less distractions. Just me and the Gem…

Google AI mode is excellent as well, which I guess is just Gemini 2.5 Flash I'd imagine as well?

chatgpt also has lots of reliability issues

If anyone from OpenAI is reading this, I have two complaints: 1. Using the "Projects" thing (Folder organization) makes my browser tab (on Firefox) become unusably slow after a while. I'm basically forced to use the default chats organization, even though I would like to organize my chats in folders. 2. After editing a message that you already sent,you get to select between the different branches of the chat (1/2, an…

It would also be nice if ChatGPT could move chats between projects. My sidebar is a nightmare.
