Release & availability
Facts from the publisher's announcement and documentation.
- Released
- Developer
- Access
- Announced October 28, 2026. Access begins this week for a subset of cyber defenders, with additional trusted partners through Google's Fairwind Program. Developer, business and consumer access has not been announced as available.
- Weights
- ProprietaryHosted access only
- Inputs
- textimage
- Context
- Not publishedGoogle has not published a Carbon-specific input context limit.
- API price
- No per-token rateGoogle announced future introductory pricing of $2 input and $10 output per million tokens when Carbon launches for developers, followed by $4 input and $20 output per million tokens after the introductory period; current standard hosted API pricing is not available.
What Google says
- Google announced Gemini 4 Carbon on October 28, 2026 as a distinct successor to Gemini 4 Argon.
- Google reports stronger coding, long-horizon and cybersecurity performance and multimodal understanding.
- Google reports an Artificial Analysis Intelligence Index v5.0 score of 59; that version is not yet part of AI IQ's approved IQ methodology.
Limitations
- Access is limited to selected cyber defenders and trusted partners; no general Gemini API endpoint is listed.
- Google has not published a Carbon-specific input context limit or current standard hosted API price.
- The announced $2 input and $10 output per million tokens are future introductory launch rates, not a current standard hosted price.
- Publisher-reported benchmark claims are not substituted for independently reconciled source results.

Measured results are shown as published
Every score in the benchmark tables comes from its source unchanged. Composite IQ averages all seven dimensions equally.
Estimates fill the gaps
Abstract Reasoning, Mathematical Reasoning, Academic Reasoning, Programmatic Reasoning, Reliability and Knowledge Work have no published results yet, so their IQ is estimated from Gemini 4 Carbon's other dimensions. Missing benchmarks can also draw on its predecessor, Gemini 4 Argon; a predecessor is an estimation input, not evidence that this model has the predecessor's measured results.
A missing result is not a zero
Benchmark versions and evaluation harnesses can differ between sources, so small gaps between models may not be meaningful.

Frequently asked questions
Quick answers about Gemini 4 Carbon, drawn from the same data as the rest of this page.
How AI IQ scores models →Get this data from the API →- What is the IQ of Gemini 4 Carbon?
- Gemini 4 Carbon has an estimated IQ of 139, which ranks #5 out of 176 public models on the AI IQ leaderboard. The score combines seven equally weighted reasoning dimensions using measured benchmark results and conservative estimates for missing coverage.
- What is Gemini 4 Carbon best at?
- There isn't enough published data to say yet. Gemini 4 Carbon has measured benchmark results in only 1 of the seven dimension AI IQ scores, and strengths are only compared once at least two dimensions are measured and ranked.
- What is the EQ of Gemini 4 Carbon?
- Gemini 4 Carbon doesn't have an EQ score yet. EQ (emotional reasoning) is calculated from EQ-Bench 4 and AttuneBench, and neither has published a result for Gemini 4 Carbon. AI IQ doesn't estimate EQ from other benchmarks, so the score appears once one of those results is published.
- Which benchmarks has Gemini 4 Carbon been tested on?
- Gemini 4 Carbon has published results on 1 of the 39 benchmarks behind AI IQ's Composite IQ, including Arena.ai Agent Arena.
- How much does Gemini 4 Carbon cost?
- AI IQ doesn't have a verified standard per-token API price for Gemini 4 Carbon, so it can't calculate an effective cost. This is common for models offered only through subscriptions, restricted-access programs, or self-hosting.
- Is Gemini 4 Carbon open source?
- No — Gemini 4 Carbon is a proprietary model. Its weights are not publicly available, so it is used through hosted APIs and products.
- Who developed Gemini 4 Carbon?
- Gemini 4 Carbon was developed by Google, based in the United States.
- When was Gemini 4 Carbon released?
- Gemini 4 Carbon was publicly released on October 28, 2026.
- How large is the context window of Gemini 4 Carbon?
- AI IQ hasn't verified an input context limit for Gemini 4 Carbon from its developer's documentation, so none is listed rather than guessing.
- How fast is Gemini 4 Carbon?
- AI IQ doesn't have independent speed measurements for Gemini 4 Carbon yet. Speed comes from independent tests of a model's hosted API, which aren't available for every model — especially new, restricted-access, or self-hosted ones.
