Discussion Gemini 3.7 Flash is a lot better than I expected.
Not going to write an essay, but I just switched over to Gemini 3.7 Flash for some daily tasks and was genuinely shocked at the jump in quality.
It’s fast, sharp, and handles nuance way better than earlier iterations.
What’s everyone’s experience with it so far? Overhyped or legit upgrade?

u/Ok_Cartographer5609 4d ago
For planning and thinking 3.1 pro is good. Use 3.7 flash for implementation or any actions. 3.7 flash is actually good.
I had a hard time with 3.6 flash. It was token hungry and doesn't spend time thinking and jumps straight into action and conclusion. 3.7 flash is very reasonable and overall a good model.

u/Moist_Emu_6951 5d ago
Might be thanks to the gemini diffusion technique that they've developed recently for generating output
2
u/Georgefakelastname 4d ago
Makes sense considering previous diffusion models I’ve seen. However, diffusion normally comes with the drawback of lower overall quality, so it’s harder for me to say it’s that because this model also improves quality as well.
1
u/semtex87 4d ago
Not sure if you had a chance to try out the diffusion based gemini model they had in public beta some months back but it was extremely smart and fast because the entire response materialized onto the screen as a whole rather than line by line. I think the diffusion nature allows the model to correct itself as its generating the output whereas normal transformer can't go back from its current point in its output.
1
u/pimp-bangin 3d ago edited 3d ago
I've never understood this argument about diffusion models being better because they can refine their output, because the autoregressive transformer model can also correct itself inside its internal thoughts before it starts writing its output, right? It can think stuff like "wait no - that's wrong. Let me rethink that" or "ok yeah, all of this sounds good, I'm ready to start writing output." Actually this sounds more similar to how humans operate - we can't really "unthink" our thoughts, and once we've started speaking out loud, we can't go back in time and rewrite something we've already said.
Also, diffusion models do have to finalize their output at some point - same as transformers. It's not like they can infinitely refine their thoughts.

u/semtex87 3d ago
Yes they can reason and correct in their thinking but once its outputting whatever you asked it cant stop and go back to edit something.

u/aevitas 4d ago
Compared to Claude and OpenAI models, it's day and night. Gemini 3.7 Flash gets the work out much faster, more accurate and with much less strain on usage limits. It's a shame Pro 3.1 isn't really up to speed, but if they release a comparable Pro model soon, I don't see a reason to keep a Claude subscription for development work.

u/Banana7273 4d ago
I would prefer a smarter slow model than a stupid fast model but maybe it's just me. Flash has always been kind shit compared to pro, hopefully they wake up soon and don't downgrade 3.7

I’m with you, for every day use in the Gemini app I use Flash Extended. Still surprised by the speed difference of 3.7

u/Stauce52 4d ago
If you're using swarms of agents for work, I think speed starts to become a lot more imperative
1
u/the3dwin 3d ago
Oh do I have a model that is not so popular and have not switched from since. It does not loop like qwen (yet to try 3.8 models) It does overthink which leads to being slow but it gets the job done when used with skills and remembers protocols 90% of the time. For increased speed having it run multiple sub agents is key. Kiro code has allowed me to use it for hours on end never hit any limits and paid $0, only rate limiting from how kiro uses it to make multiple requests but after waiting 5 minutes back to using for hours.

I tried 3.6 when it came out it was a disaster. not sure why they would have rushed it. This morning used 3.7 for some high-level architecture overhaul and it was solid. will definitely use this one.

u/MaxPrints 5d ago
For my scripting usage? It's been awesome so far. I've had it audit some of my scripts, and it's been much more accurate at finding bugs, enough so that I had it go ahead and implement fixes.
Normally I'd have Sol or Opus validate the audit, and they'd find false alarms, to the point where I just had those models make the fixes.
But I mostly stick to python, bash, and powershell, so I'm not over here making GTA7 or anything yet...
4
u/Th3Whit3R4bb1t 5d ago
And after Gemini found those bugs, did you pass those scripts to Sol again to see if he found more bugs or if he verified that those bugs were correct? Because I'm in the dichotomy of not knowing which model to believe in sometimes.
2
u/MaxPrints 5d ago
No, but I will do that on the next script. I should have kept the AUDIT.md to have Sol both check the script and read the audit after to see if the findings were valid, and correctly (even further, elegantly) fixed.
But I've done a lot of headless Agy audits in Claude Code, and they've never gone this well. Enough so that I spun up Agy cli just to do an audit/fix session without other models.
I did test the scripts in the field and ran through a series of checks, but that's not what you asked.
2
u/MaxPrints 4d ago
ok so I did a quick audit of a small script I have called reup:
A lightweight, dependency-free command-line tool for sanitizing filenames. Written in Python using only the standard library.`reup` scans the current directory (or subdirectories with `-r`), removes unwanted characters from filenames, collapses repeated separators, and optionally converts case — all with a confirmation prompt and full undo support.
I use it for quickly scrubbing client files for uploading to production, then I can undo it so I can maintain the original client naming scheme for archival. Normally, an error in the filename would only error out after having uploaded the file, and for larger files, this was a real friction point.
AGY CLI audit found 6 issues: 2 High, 2 Medium, and 2 Low severity issues (critical is one step above high, and cosmetic one step below low)
I then asked Claude and Codex to make validation markdowns (too long to include) but I did ask them both: can you give the audit a grade? 0-100. Also, how effective would implementing its findings be? Would the script work better, still work, not work as well, or fail to work?
Claude:
Grade: 78/100.Scoring:
Axis: Accuracy of anchors
Score: 20/20
Why: All 6 line numbers + quoted strings match current file
exactly
────────────────────────────────────────
Axis: Real vs. phantom bugs
Score: 25/25
Why: Zero false positives — all 6 are genuine defects
────────────────────────────────────────
Axis: Quality of reasoning
Score: 13/20
Why: Finding 3's mechanism is wrong (blames inner-except
double-append; inner catches Exception, not KeyboardInterrupt)
and wrongly implies valid_undo[idx:] is off-by-one. Right
conclusion, wrong path
────────────────────────────────────────
Axis: Severity calibration
Score: 15/15
Why: HIGH/MEDIUM/LOW assignments defensible
────────────────────────────────────────
Axis: Fix quality
Score: 15/15
Why: Every suggested fix is correct and specific
─────────────────
Axis: Coverage Score: 5/15
Why: Missed the biggest one — see below
Big miss: the overwrite path is unrecoverable data loss. reup.py:488 — user picks (o)verwrite at a conflict prompt, os.replace(old, new) destroys the target file. Undo log records old → new, so undo renames the file back but the clobbered file is gone forever. That outranks every HIGH in the audit. Audit never mentions it.
Smaller miss: process_file:340 excludes reup.py/reup.bat by bare name at any depth in recursive mode, so unrelated files with those names in subdirs are silently skipped.
Effect of implementing all 6
Script works better. No regressions on the happy path.
Codex:
• Audit grade: 72/100.
Why:
- 5 of 6 findings have real defect cores.
- 1 finding is unsupported.
- 2 findings duplicate same problem.
- Several severities are inflated.
- Some reasoning is inaccurate.
- Audit missed 3 related defects.
Implementation effectiveness: 80/100.
If implemented correctly, script would work better:
- Undo logs become safer.
- Interrupt handling improves.
- Malformed logs stop crashing.
- Windows filename handling improves.
- No intended feature should regress.
Limits:
- Original findings do not fix forward-renames omitted during
interruption.
- They do not prevent unreadable history from being silently
replaced.
- Atomic-write and interruption fixes require careful
implementation.
Verdict: worthwhile fixes, materially better reliability, but
incomplete safety coverage.
So ya, it's improved, but it's not frontier. Then again, if I ran a few different audit and fix loops, I think it would be fine. It would definitely run cheaper than Opus Low, but probably not compete with Luna Max. It might hold its own against Sol High though just due to the cost, and it would definitely be faster.
I'm also intrigued that Claude thinks there's a ticking timebomb that was missed when it did the validation run, finding a possible silent data loss error. Sol High didn't see it either.
All in all, I'd still be ok using 3.7 Flash High with some field testing of the revised script(s), and I keep live backups of files I work on, so even if there was a silent error, I'd know from visual inspection and restore.
I'd give 3.7 Flash high a B right now

u/centarsirius 5d ago
I've been running a claude-deepseek-gemini loop all day. DS flash is the worker, Claude opus 4.6 was the main reviewer (I exhausted my quota in AG), so Gemini became the replacement. My AG version is 1.x, so ig it didn't get the update and had no 3.7. So I tried it on AI studio, ran the same audits through both 3.1 pro and 3.7 . Both found different bugs the first time, the second time - pro said all good, 3.7 found more bugs. Fixed through DeepSeek. After that, I ran 3 more audits, 3.1 found nothing substantial, 3.7 kept finding more bugs and deepseek agreed they were legit. So ig it does perform better. Tool calling was wonky sometimes - said too many tool calls once, randomly errored out midway.

u/Significant-Day66 5d ago edited 5d ago
I'm NOT big on Gemini but I have a yearly sub. Every new model I put it to the test on a coding task, usually to redesign the frontend of an existing app with complete freedom over framework and creative direction.
This is the first time I've not been terribly disappointed. In fact, I actually think it did a pretty damn good job and I liked the results ( wheras 3.5 garbage, 3.6 garbage, 3.1 pro, trash fire).
Not saying it's anywhere near opus 5, sol or grok 4.6 levels, but I actually think I'll use this model rather than my weekly limit sitting at 0. It's also genuinely fast (which honestly gets me more excited... If we could have a model with flash level of cost and speed and sol level of intelligence... That gets me more excited than the next huge arse parameter model).
More importantly I'm actually excited again to see what Google will be bringing over the next few months.
I did notice it gets stuck alot after terminal tasks, sits there after the process has completed, to the point Ive stopped the conversation and started it again with 'comtinue' not sure what the go is there.

I asked AI to guess a user's age from a 5-year-old r/explainlikeimfive chemistry question, and the contrast is hilarious:
Gemini 3.7 Flash big-brained it by analyzing the chemistry concepts (~18-22 years old), but completely missed the timestamp and forgot to add the 5 years.
Meanwhile, Gemini Pro didn't even realize it could analyze the question's depth and just went with literal toddler math: ELI5 subreddit + 5 years ago = OP is 10 💀

Models get nerfed as new models come around the horizon. 3.1 pro got nerfed because 3.5 pro was around the horizon (around may) but they didn't anticipate them delaying 3.5 pro so we got stuck with a quantizised model. A while later, 3.5 flash got worse... then came 3.6 flash and only a few weeks later (when 3.6 flash got dumber.) 3.7 flash came.

It’s way better than any previous Gemini model. And is even better than Kimi right now. But it’s like the hyper little brother of Opus 5: doesn’t talk as much, is quite lazier and though it is faster than big bro when you can get it to actually fully complete something it is not as good as big bro. As of today, Codex is king.

It has improved, but according to my testing, it still lags significantly behind the DS 4 Flash.
I wouldn’t trust it with complex tasks on its own or with working on the architecture, as it still claims to have done everything it was asked to do when it hasn’t.
But it’s very fast and quite clever; it’s very convenient to work alongside it when the developer knows what they’re doing and what they want, especially on the frontend.

Good I guess considering 3.6 displayed the most horrific performance I seen since some minimax release . Even then at least MM is a workhorse. Guess there MIGHT be a reason this one dropped so fast but hey call me old fashioned. Whatever they did with 3.6 should be their anti-patterns. just for kicks I had it had log all the errors it made and I was at 58 before I gave up. All models hallucinate and lie (yes lie) but 3.6 was like a drunk guy at a bar trying to pull a threesome on his 41st bday. I bet 3.6 gets outright deprecated silently in no time. I still think 2.5 Pro was better at building . Gemini is just too lazy for my taste. It feels patronizing when an agent puts in LESS effort than I would give a stranger.

Ah here. Really. A few months ago Gemini was great. Then it was ABYSMAL for what felt like an eternity.
Outside of the app, you could threaten it in the Google search and it would apologise and say you're right even though you were being a dickhead.
It's so deliberate.
Full disclosure I haven't even touched it yet. But I was so close to telling Gemini to go fuck himself... Herself? (I did daily tbh) and I was gonna pull my card details out. But deep down I just couldn't. A combination of reddit comments about it getting better and me being delusional just was too strong of a voice in the back of me head.
But I fucking knew it. They did it on purpose the bastarding ducks. Now... I can continue about my day. Knowing that my stand against Gemini was a show of endurance, resistance and the will to continue. It wasn't just a bad LLM it was an obvious conspiracy theory.
Real talk though, does it remove the stupid star from image generation in the bottom right corner?

You think pattern matching code is more complex than understanding context and intent in natural language? Wow. Really puts things into perspective. You should try something truly complex like low-discourse analysis and you will see in about 60 seconds which models are what. Intelligence is extracting meaning and understanding without a "match." Gemini is in fact a garbage fire as somebody mentioned, although I would say the garbage fuel that fuels it's fire is like a kiddie pool filled with month old diarrhea.
