Google releases Gemini 3.8 Flash, three weeks after Gemini 3.7 Flash, for an introductory price of $0.75/1M input and $3.75/1M output tokens until December 31

After the last model release three weeks ago, Google today is rolling out Gemini 3.8 Flash. This marks the third Flash update in three months.

Context & Ripple Effects

Google had already reset Flash pricing with Gemini 3.6 Flash’s lower token rates, then introduced Gemini 3.7 Flash in August at $0.75 per million input tokens and $3.75 per million output tokens. Gemini 3.8 arrives three weeks later at those same introductory rates, extending a sequence of frequent model revisions rather than another price cut.

Google’s public launch messaging places 3.8 Flash in AI Mode and the Gemini app for AI Pro and Ultra subscribers, while Sundar Pichai characterized the update as improving software engineering, agentic tasks, and multistep reasoning. The broad same-day pickup shows the release cadence itself has become part of the story.

First-order effects

Google API customers receive a newer Flash option without a higher introductory per-token rate than the August 3.7 Flash launch, through December 31.
Google AI Pro and Ultra subscribers gain 3.8 Flash in Google’s AI Mode and Gemini app, tying the model refresh directly to Google’s owned consumer surfaces.

Second-order effects

Stable 3.7-to-3.8 token pricing shifts the comparison for developers toward task performance and release-management overhead, rather than a new list-price premium for the newer Flash model.
Google’s Search and Gemini teams can use the faster Flash release cycle as a product-refresh lever, while customers building on the API must evaluate models more frequently.

Third-order effects

If Google sustains rapid Flash revisions at steady or lower token prices, the commercially relevant model may become a moving performance-and-cost frontier rather than a long-lived API SKU.
The pattern strengthens the importance of effective inference cost: providers’ advantage depends on delivering better agent and coding output without raising the per-token bill for buyers.

The trend: Fast, price-disciplined model refreshes are making inference economics and deployment cadence central competitive variables for AI platforms.

Less than three weeks after 3.7, we're introducing Gemini 3.8 Flash 🚀 Available today in AI Mode in Google Search and the Gemini app for Google AI Pro & Ultra subscribers. Check it out!

Today we're introducing a new 3.8 Flash model, our 3rd Flash release in just 6 wks. It delivers significant leaps from 3.7 Flash across software engineering, agentic tasks, and multi-step reasoning. On DeepSWE v1.1, it outperforms most larger frontier models in autonomously solvi…

Google have, dare I say... RELEASED A GOOD MODEL 🥹 Gemini 3.8 Flash provides ~Opus 5 performance at much lower cost, while being super fast

Google has: 1. The worst harness of any lab 2. The worst code apps of any lab 3. The only lab with zero 3p integration option 4. The most painful bans (since it's your full Google acct) 5. The most trigger-happy ban policies It is a legitimate risk to use Antigravity stuff until …

I don't think people understand just how risky it is to try and use their Google Gemini subscriptions outside of Google's official surfaces. You can get your ENTIRE GOOGLE ACCOUNT BANNED. OpenAI or Anthropic ban? Annoying but whatever Google account ban? Legit life ruining.

Gemini 3.8 flash looks like a real banger Opus 5 coding quality but at a fraction of the cost and super fast And none of this is even accounted for the fact the model is natively multi modal This is going to be so awesome for things like making remotion videos

Gemini 3.8 flash is a big improvement over 3.7, especially in terms of user satisfaction. Double-digit lift in the percentage of explicit user praise. Also better at steerability and bash. It's cool to see that models can still see a raw 20% jump in performance these days.
@valsai @valsai on x
Gemini 3.8 Flash scores 62.3% on the Vals Index, fifth behind Fable 5.1, Opus 5, Fable 5, and GPT-5.6 Sol. 3.8 Flash is within 5pts from the leader at a fraction of the price - putting it on the Pareto frontier.

3.8 Flash is the same price as 3.7, is ~the same speed, and is available via the Gemini API, in AI Studio, Antigravity, Gemini App, and more! Read more: https://blog.google/... So incredible to see the progress and hard work from the team. Pushing hard to be at the frontier.

Had early access to Gemini 3.8 Flash, it is a very good Flash model, but not equivalent to a frontier model, though. Here is Gemini 3.8 Flash's version of the shader with the same prompts (which it provided very quickly)
@dalmaer Dion Almaer on x
Wasn't 3.7 just released? Yup, models are cooking super fast now and this means, you can jump in and use Gemini 3.8 Flash... and the design quality is so much better in my testing (and our evals!).

Gemini 3.8 Flash on DeepSWE 1.1, scores 73.7%!
@burkov @burkov on x
Same price and same speed mean that Gemini 3.8 Flash is currently the best model to be used as a general-purpose API. Based on the benchmarks, it has a high chance to also be the best model for coding, but this will take time to test.
