Is Jev better than Gemini?

They do different jobs. Gemini writes and reasons and can read images, audio and video; Jev only returns typed decisions with probabilities from text. For classification, scoring and routing of text, Jev is far cheaper; for anything written, or any media, you still need a language model.

Is Jev cheaper than Gemini?

On list prices, yes: $0.042 per million input tokens with free output, against $0.10 to $0.30 per million input tokens for Gemini's small Flash-Lite models, plus output charges. In one independent test of 791 labelled decisions Jev cost about six times less than Gemini 3.5 Flash-Lite. That test measured cost, not accuracy.

Does Gemini have a free tier?

Google's pricing page lists a free tier for several models, including the Flash and Flash-Lite ones. Check the page for the current terms before you plan around it.

Can Jev read images or audio?

No. Jev takes text. Gemini 3.5 Flash-Lite accepts text, images, video and audio.

Can Jev replace Gemini?

Not for writing or for media. Many teams keep a language model for that and use Jev for the high-volume decisions around it.

[ In short ]

Gemini writes, reasons and reads images, audio and video. Jev only returns typed decisions with probabilities from text. On list prices Jev is about 2.4 to 7 times cheaper per input token than Google's small Gemini models, and in one independent test it cost about six times less than Gemini 3.5 Flash-Lite per 1,000 decisions. Google also offers a free tier on some models.

Side by side

Feature	Jev (TypeSafe AI)	Gemini (Google)
What it is	A decision model: it answers typed questions about an input and returns probabilities. It cannot write text.	Google's family of language models. They generate text and handle open-ended tasks.
What comes back	A typed answer with probabilities and a confidence value	Text, which your code then has to read and check
Input	Text only	Gemini 3.5 Flash-Lite takes text, images, video and audio
Price per million tokens (input / output)	$0.042 / free	Gemini 2.5 Flash-Lite $0.10 / $0.40; 3.1 Flash-Lite $0.25 / $1.50; 3.5 Flash-Lite $0.30 / $2.50; 3.8 Flash $0.75 / $3.75 until 31 December 2026, then $1.50 / $7.50 (Google's pricing page, updated 14 October 2026)
Free tier	Not covered in the TypeSafe pages we checked	Google lists a free tier for the Flash and Flash-Lite models
One measured task: 8-way routing, cost per 1,000 decisions	About 1.5 cents	About 8.7 cents (Gemini 3.5 Flash-Lite)
Can it write, reason or code?	No	Yes

Prices are as published on Google's pricing page, updated 14 October 2026, and can change. The measured cost comes from one independent test and covers cost only, not accuracy. Jev's input and output prices are from TypeSafe's documentation.

The short answer

Gemini is a family of language models from Google. It can write, reason and, depending on the model, read images, video and audio. Jev does not generate text: you define the questions and the allowed answers, and it returns a probability for each. Jev takes text only. The two answer different needs, so for a pipeline the pattern is often both: Jev for the high-volume decisions, Gemini for the writing and the media.

What Google charges

Google's pricing page lists many Gemini models. For the small, cheap ones, per million tokens (input / output): Gemini 2.5 Flash-Lite $0.10 / $0.40, 3.1 Flash-Lite $0.25 / $1.50 and 3.5 Flash-Lite $0.30 / $2.50. Larger models cost more: Gemini 3.8 Flash is $0.75 / $3.75 until 31 December 2026 and $1.50 / $7.50 from 1 January 2027, and Gemini 4 Argon is $2 / $10 until 30 November 2026 and $4 / $20 from 1 December. Jev lists $0.042 per million input tokens and no charge for output.

By our arithmetic from the list prices, Jev is about 2.4 times cheaper per input token than Gemini 2.5 Flash-Lite, about 6 times cheaper than 3.1 Flash-Lite and about 7 times cheaper than 3.5 Flash-Lite, and its output is free. Google also lists a free tier for several models, which can cost nothing at low volume. Per-token prices are not the cost of a whole task, so the measured test below matters more.

What an independent test measured

One third party, AY Automate, measured the cost per 1,000 decisions on 791 labelled decisions, run on 19 September 2026, comparing Jev with Gemini 3.5 Flash-Lite and GPT-5.4 nano. Against Gemini 3.5 Flash-Lite, Jev cost about 1.5 cents against 8.7 cents for 8-way routing, 4 cents against 30 cents for 77-way routing, and 1.4 cents against 8.6 cents for a prompt-injection check, roughly 5.8 to 7.5 times less.

This test compared cost, not accuracy. Jev used more input tokens for the same text, but its lower price and free output still made it cheaper.

What we could not compare

Before you rely on any of this:

The cost test says nothing about which model gets more decisions right. TypeSafe's own workflow evals do not include a Gemini model.
Prices change, and Google's page already lists increases scheduled for the larger models.
Jev reads text only. If your input is a photo, a recording or a video, Gemini can take it and Jev cannot.
Your questions and data will behave differently from any published test. Run both on a labelled sample of your own.

Which should you pick?

Based on what is documented today:

Choose Gemini if the output must be written, if the task needs reasoning, or if the input includes images, audio or video.
Choose Jev if you make the same text decision thousands of times from a list of answers you define, and cost and speed matter.
Check the free tier if your volume is small: Google's free tier on the Flash and Flash-Lite models may cover it.
Use both when unsure: let Jev triage the text, and pass only the items that need more to Gemini.
