    Currently top at https://deepswe.datacurve.ai - beating Opus 5!

    https://artificialanalysis.ai/models/gemini-3-8-flash shows an intelligence score of 59, the same as Opus 5!

    Wow - for a flash model this seems to benchmark powerfully. Remains to be seen what it is like to use.

    • theHocineSaad 16 minutes ago
      As of writing this comment, Claude Opus 5 has an intelligence score of 63, not 59 (it's not the same as Gemini 3.8 Flash).

      With a score of 59, Gemini 3.8 Flash is in eighth place, falling behind even Grok 4.6, Kimi k3, and GLM 5.3.

        They are all much larger and more expensive models. Google does not have a frontier model right now, but for cheap ones, they are better than event the chinese models now.
    • markasoftware 30 minutes ago
      On artificial analysis it's only equal to opus 5 medium effort. Opus 5 max scores 63.

      Further, opus 5 medium outputs 4x fewer tokens to achieve the same result, negating a lot of the speed difference.

        A comparison to an artificial score and a comparison to “the same task”

        These folks must laugh themselves to sleep. This whole industry hoodwinked the masses. It’s impressive.

      A fifth of the cost of Opus 5! Google is certainly pushing the completion with this.

        Gemini hasn't failed me for personal usage yet. I haven't had the opportunity to use it at work.
    • WarmWash 37 minutes ago
      The benchmark also doesn't include speed. You almost think something has gone wrong when using it because it returns full responses so incredibly fast.
      • scrlk 30 minutes ago
        Not just speed, also reliability. IME, Gemini's speed and quality doesn't degrade badly during weekday working hours compared to OAI, and especially Anthropic.
        • ford 15 minutes ago
          I've had Gemini model API use degrade the most out of OAI/Anthropic/Google (often "over capacity" vs true failures)

          Not sure on consumer/product use though

    • onlyrealcuzzo 31 minutes ago
      The rumor is that 3.9 is an equal improvement in all directions, and that it should be another fast follow on like 3.7 and 3.8 were.

      It's almost across the board better than Terra at less than half the price. 3.9 is likely to approach Sol at the 1/10th the price.

      Hopefully OpenAI releases Astra first, and it's not only better than Sol but significantly cheaper, too.

      Crushing it on DeepSWE is a very big deal. Excited to give this a try.

      Wait a week with your judgement - most likely, Google is just bench-maxing very hard. If you look at the previous Flash models and the announcement on Google I/O, it was an absolute disaster. Reality diverged very much from the marketing (supposedly great benchmarks).
    • satvikpendem 34 minutes ago
      We'll see about that. I suspect benchmaxxing as all the labs do as I haven't found Gemini models to be nearly as good in agentic engineering compared to Claude or GPT models.
      • NitpickLawyer 14 minutes ago
        If anything, gemini models are the least benchmaxxed out of any lab, IMO.
      • onlyrealcuzzo 30 minutes ago
        And the benchmarks agreed with you... until now.

        So, yes, maybe it's still not - but this would be the only time it would be highly suspicious / obvious benchmaxxing / obviously bad benchmarks.

    • sunaookami 34 minutes ago
      >shows an intelligence score of 59, the same as Opus 5!

      ...on Medium reasoning. Claude Opus 5 (high) is the default in e.g. Claude Code and scores 61. Still very impressive.

  • jampa 8 minutes ago
    I've been using Gemini 3.7 for my personal trip planning app. Across multiple benchmarks, it ranks higher on everything I tried:

    - Real world knowledge (when a thing opens and closes, the geographic region, historical facts). It's also the best at taking a cluster of places and working out a visiting order.

    - Photo ranking (which photo should be the hero). Gemini can tell whether a photo is of the thing or of the view from it.

    - Document parsing (extracting the relevant trip info from PDFs).

    If you use LLMs for anything other than coding, I definitely recommend not discounting Gemini like I did just because other models are more popular.

    • tziki 7 minutes ago
      "Claude 3.7"?
      • jampa 5 minutes ago
        I asked Claude to fix the grammar of my comment, and it changed "I am using 3.7 for" to "I've been using Claude 3.7", so they sneaked their own name on it.
        • trial3 1 minute ago
          incredible. further evidence supporting my personal stance to never ever let an LLM write or edit my writing intended for another human being to read. this is all me, baby
  • a11r 13 minutes ago
    Looks like the strategy of regular updates with incremental improvements is working out well. Interestingly, the biggest jump in Artificial Analysis Intelligence Index score is for reasoning level Medium ( 3.7 was 51, 53, 57 for Low, Medium and High, 3.8 is 52,57, 59 respectively). I think scores at lower reasoning levels are more indicative of model capability since higher reasoning levels are focussed on benchmaxxing. We use the lowest reasoning level in production with good results.
    • Jcampuzano2 8 minutes ago
      I'm not an expert but I agree with your statement on the lower reasoning levels.

      Lots of models seem to just allow the model to "bloatmax" tokens in order to get bumps at high/max reasoning levels. Many of the max reasoning levels allow models to use up to double or more the tokens the next lowest reasoning level uses. Its basically only useful for people who have no cost or time stipulations on anything.

      I think I actually preferred it when we had models that either had reasoning enabled or didn't.

    After struggling with Gemini for months, I think the trick to getting the most out of the model is writing a really solid personal intelligence/instructions prompt. The results are night and day in terms of performance.
    • dakolli 0 minutes ago
      slot machine addict thinks if he pushes buttons in a certain order the odds get better.

      In all seriousness, gemini has the best interactive planning document/orchestration. Tell it to create a plan document and work through it with it and it will do incredible much better (in antigravity products). But this is the case with plan modes with every model, I just think the interactive document that antigravity uses is really well thought out.

    Wait, I didn't realize 3.7 Flash was already beating Sol on a bunch of the benchmarks. Isn't it a way smaller models?
    • ipsod 41 minutes ago
      IDK if it's smaller, but I know it's way faster. In one test I did, Flash 3.7 high was ~9.4x faster than Luna High.

      But, also... Sol crushes Flash 3.7 at writing code in a codebase of any size beyond "tiny".

      Flash is my go-to for prototyping, and basically anything that isn't writing production code.

      • ramon156 34 minutes ago
        The only company with a proper TPU set-up is bound to have the fast models, now add a market cap like Google to the mix.
        • ipsod 30 minutes ago
          They've been my bet to win the AI race for a while. I was starting to doubt, but this 3.6, 3.7, and 3.8 arc has anchored me.
      • esafak 27 minutes ago
        Luna is way slow. I don't remember an OpenAI model ever being this slow.
        • dannyw 18 minutes ago
          Are you using direct or via OpenRouter? I think OpenRouter Luna always uses the `flex` tier, which is quite a bit slower.
    • realist_not 41 minutes ago
      It's pretty good if you can actively steer it , its actually really really good , the antigravity free tier and pro tiers are generous as well . I'm shocked at how fast it generates tokens.
      • worldsavior 17 minutes ago
        Some would say it's Google's TPUs.
    • refulgentis 13 minutes ago
      They're quite selective in benchmarks, c.f. only notably based one is 10% on TerminalBench. It's a really addled model, one time I said "Hi" and it built out a 4 panel hello world app with (fake) weather, a todo list, and a couple other things I forgot. I wouldn't be comfortable saying "ignore the #s!" except when I complained it was trash and way overcooked on agentic coding yet not good at it, and a couple DeepMind ML people liked the tweet.
  • meh2frdf 33 minutes ago
    The flash models, for coding are reckless in my experience. I have a Ultimate subscription, get good quota, but still use Opus 4.6 as it's much more reliable if you manage the context window carefully.
    • datlife 21 minutes ago
      I use Flash model as code implementation executor, then have GPT-5.6-Sol or Opus to review the work. Pretty good so far and presumably less expensive.
    • onlyrealcuzzo 29 minutes ago
      > The flash models, for coding are reckless in my experience.

      My experience is that antigravity is awful and reckless - but that the model itself isn't.

    • upcoming-sesame 28 minutes ago
      If by reckless you mean commit, push, deploy without me asking it to, the I agree!
      • tiborsaas 23 minutes ago
        It even took my girlfriend on a date, now it prepares for IPO, how do I turn it off?
      • okdood64 23 minutes ago
        Respectfully: If it's able to deploy without you asking it to, that's a you problem. There are no safeguards?
        • wongarsu 11 minutes ago
          That's exactly how you get 'you are right, I deleted the production DB to apply the new schema when I should have written a migration'

          That said, I do trust Opus and Fable enough to let them deploy to staging. Great for debugging. Just don't give them keys for prod

        • meh2frdf 19 minutes ago
          You need more safeguards for sure, but also it tends to fly off down rabbit holes, rebuilding things in dumb ways, hacking around things, making assumptions etc, it seems very eager to go 'ta da! I did it look how quick I was', sometimes it nails it other times it created a lot of tech debt.
        • meh2frdf 17 minutes ago
          Also if it ever says, "I've found the root cause of ..", it definitely has not found the root cause and is making a non evidence based guess as it has run out of ideas.

    Wow this comes after what - 3 or 4 weeks since 3.7 Flash, which was also 3 or 4 weeks after 3.6 Flash IIRC?

    I eagerly wait more info but sounds like Deepmind without Demis calling the shots has been unleashed and are operating at full speed? Shocker!

    At this point it is a meme of course, but where is 3.5 Pro :)

    • meetpateltech 32 minutes ago
      According to the WSJ, 3.5 Pro is reportedly being skipped entirely, making Gemini 4 the next flagship model after post-training.

    • hiddencost 19 minutes ago
      A month is not enough time for any meaningful change in an organization the size of Deepmind/Google. These models were surely the result of work streams and teams that started under Demis. I think Demis can safely feel proud Deepmind is getting back on track.
  • wjellyz 1 minute ago
    been absolutely loving 3.7 flash for coding. it feels very fast and quality is decent for implementing product features. usually use opus or sol for hardcore debugging.
  • xnx 44 minutes ago
    Seem like a great, no-compromise, upgrade over 3.7 which is already a bargain, fast, and doesn't have the brain-damaged writing style of Claude.
    • fitsumbelay 42 minutes ago
      that's certainly what it's looking like so far. kind of mind boggling ...
  • simonw 14 minutes ago
    The most interesting thing about the Gemini models is still their multi-modal support: they accept audio and video input, OpenAI and Anthropic's flagships are still image-only.

    Gemini Flash is also pretty cheap, so it's a great family for performing media analysis, like extracting structured data from images and video.

  • buntp 7 minutes ago
    It seems like this is one of the most powerful models for the price, really didn't see that coming from Google
  • simonw 28 minutes ago
    Pelicans (thinking effort high, medium, low): https://tools.simonwillison.net/markdown-svg-renderer?url=ht... - high cost 8.9742 cents

    Here are the 3.7 pelicans for comparison: https://tools.simonwillison.net/markdown-svg-renderer.html?u... - high cost 8.4387 cents

    (I think thinking level low is a regression on 3.8 compared to 3.7.)

    • onlyrealcuzzo 24 minutes ago
      This is in comparison to Fable:

      > https://tools.simonwillison.net/markdown-svg-renderer?url=ht...

      > Took just under 14 minutes to generate, and at 65927 output tokens cost me a hefty $3.30!

      So 50x cheaper - and how much faster?

    • world2vec 24 minutes ago
      I mean no offense but these pelicans are a bit tiresome and a very meaningless benchmark. There's no real difference between any of these svgs across models and model versions anymore.
      • wongarsu 17 minutes ago
        If everyone agreed with you, the comment would disappear near the bottom of the thread

        I like the benchmark. Yes, it's near saturation for SotA models, but still quite good to show where smaller models stand in relation to SotA

        In this instance, I see a great image, but consistently clipping mudguards (both in 3.8 flash and 3.7 flash)

  • satvikpendem 35 minutes ago
    Is the Gemini CLI still terrible compared to Claude Code and Codex? The harness the main thing holding back Google models as they could've been the best given all the advantages in compute capacity and training data they initially had, where now even the Google CEO said they're falling behind in agentic tasks, which is sort of a vicious cycle because RLHF relies on human usage.
    • stwrt 22 minutes ago
      In May they replaced the Gemini CLI with the Antigravity CLI.

      https://developers.googleblog.com/an-important-update-transi...

    • rancar2 28 minutes ago
      That was sunset and replaced by Antigravity. FWIW until I abandoned it knowing the sunsetting, I was able to get good behavior out of Gemini CLI with overriding the system prompt. The default prompt crippled the harness with very poor instructions, but there was a hidden ENV to override it. Replacing it with Claude Code like prompts based on the model selected, it ran at a much higher intelligence level full stack with significantly less errors.

      It is still going to be better at text work, skills, document review, deep reasoning, architecture review, etc. It is only 6 months old, it isn’t like its world knowledge and software knowledge is really out of date. Use it to churn on harder design problems.

        [1] For tone and instruction following, a positive percentage increase represents an improvement in the tone of the model on sensitive topics and the model’s ability to follow instructions while remaining safe compared to Gemini 3 Flash. We mark improvements in green and regressions in red.
      
      Gemini 3 Flash?! So is Gemini 3.8 Flash less safe than 3.7 Flash in all areas besides Text to Text Safety (and identical on Image to Text Safety)?

      Why bother with a column “Gemini 3.8 Flash vs. Gemini 3.7 Flash” when you’re going to disregard the label for 20% of it? Also is the “Tone” label short for “Tone and Instruction Following”?

      Gemini 4 pre training is underway: https://x.com/OfficialLoganK/status/2079594867161022817

      My guess is we skip 3.5 and go straight to 4 Pro. With the monthly Flash releases, releasing 4.0 Flash and Pro in 6-8 weeks would be a nice buildup.

      (I work at Google but don't know anything that isn't already public)

    • WarmWash 42 minutes ago
      Latest rumor is that 3.5 pro was struggling to be meaningfully better than flash, since iterations on flash were moving much faster than iterations on pro, likely due to model size (flash is estimated to be in the 200-400B range).
      • VirusNewbie 31 minutes ago
        I found 3.5 pro to be much better than 3.5 flash, but 3.7 flash with high reasoning is comparable and way way faster.

    I'm trying it now for token heavy coding tasks, it's capable for many tasks but in noway compares to Claude/Sol - requires more prompts and the output isn't as good.

    So just another mid-tier flash model, nothing exciting, but Antigravity has very generous quotas so it's a good workhorse model when your Claude/OpenAI subs run out.

    And whilst it's a fast model, having to baby sit through and approve prompts every few seconds ends up making it slower than the Auto approve modes of Claude/ChatGPT - they definitely need an auto approve mode.

    One place where I find the Flash models surprisingly bad is Google Search's "AI Mode".

    A recent example - I searched for how to unsubscribe from Pearson emails. Google Search "AI Mode" confidently gave me a sequence of steps along the lines of Settings > Profile > Email preferences > Unsubscribe.

    Of course, I looked for an unsubscribe link before asking Google. None of those options existed. The correct answer was there is no way to unsubscribe through the account, so I just blockthe emails instead.

    I've run into this pattern quite a few times. AI Mode seems to make up things all the time.

    • inventor7777 22 minutes ago
      I think that's just a limitation on the size of the model. I'm pretty sure that they use a pretty small model in those summaries to save money, which naturally makes them a little less smart.
    • xyzzy_plugh 10 minutes ago
      It's not the models, it's the guardrails.

      It's obvious that the Google Search AI Mode encourages the model to give an answer without spending unnecessary cycles investigating deeply.

      They also heavily encourage keeping the context short. For example, it will remove the option to start a new turn after a small number of turns, depending on the topic.

      It definitely makes things up all the time, but it gets it right surprisingly often. I really like it.

      >We will not send marketing emails to a user who has opted out of receiving them. Any marketing communications we send will include an unsubscribe link at the end of the email.

      I don't think this is AI's fault. This is Pearson's publishing incorrect information and the only way to really know they are a bunch of lying assholes is to have an account and try to unsubscribe from it.

      AI didn't make it up, Pearson's did.
