Cost/1M tokens
Google DeepMind's Gemini 4 Carbon is a frontier model that the launch announcement says builds on Gemini 4 Argon, released two weeks earlier. The maker says it improves on its predecessor in cybersecurity and long-running agentic tasks, reporting more than twice the success rate at generating secure code. It is built for sustained engineering work such as finding vulnerabilities, checking whether they are exploitable, and producing fixes.

API and pricing
$2.00 per 1M input tokens and $10.00 per 1M output tokens. Across the 7 tracked paid providers, input prices range from $1.00 to $3.60 per 1M tokens.
Google AI Studio. It charges $1.00 per 1M input tokens and $5.00 per 1M output tokens, the lowest blended price at a 3:1 input to output mix.
Yes. Cached input costs $0.10 per 1M tokens versus $2.00 uncached, a 95% discount, and cache writes cost $0.1875 per 1M tokens.
No. Google AI Studio offers batch pricing at $1.00 per 1M input tokens and $5.00 per 1M output tokens, but the batch input discount versus standard is 0%.
$0.015 at the cheapest provider, Google AI Studio, for a typical request of 10,000 input tokens and 1,000 output tokens.
In the last day, 3 of 7 endpoints with uptime data ran at 99% or better. The best uptime was 100.0%, by Google and Google AI Studio.
