The release is real and confirmed on Google's own channels. Google's announcement states that, building on 3.7 Flash from three weeks earlier and marking its third Flash release in six weeks, it is introducing Gemini 3.8 in two variants: Gemini 3.8 Flash, described as its most intelligent workhorse model with improvements from 3.7 Flash across software engineering, agentic tasks, and multi-step reasoning . On pricing, the announcement says directly: "It is available at the same introductory price 1 as 3.7 Flash at $0.75 per million input tokens and $3.75 per million output tokens."

The docs attach a condition the post does not carry. Google's developer documentation states that the $0.75/$3.75 rate is introductory through December 31, 2026, and that standard pricing of $1.50 per million input tokens and $7.50 per million output tokens takes effect January 1, 2027. The same page notes that Gemini 3.8 Flash can use more tokens on longer running and complex tasks by design, taking smaller reasoning steps, calling tools iteratively, and verifying its work . Google Cloud's pricing page confirms the same introductory rate and end date applies to 3.8 Flash, 3.7 Flash and 3.6 Flash alike, with standard pricing of $1.5/$7.5 from January 1, 2027 .

Independent evaluation partially corroborates the improvement. Artificial Analysis reports that with high reasoning, Gemini 3.8 Flash scores 59 on its Intelligence Index, up 3 points from Gemini 3.7 Flash, matching Gemini 3.7 Flash's discounted pricing until the end of the year, and sitting on the intelligence versus cost-per-task frontier at $0.58 per task, which is about 40% higher than its predecessor, driven by a 30% increase in average output tokens per task . Artificial Analysis attributes the index gain primarily to stronger performance on agentic evaluations including tool use, Terminal-Bench v2.1, and GDPval-AA v2 .

On the benchmark table itself, the numbers are Google's. One analysis notes that on Google's announcement table the reported figures are DeepSWE v1.1 73.7% versus 65.3%, Terminal-bench 2.1 89.4% versus 85.8%, OSWorld-2.0 59.0% versus 50.6%, Vals Finance Agent v2 61.4% versus 59.0%, and HLE-Verified 54.9% versus 53.6%, with every published row moving up, and that all numbers are Google's own runs . The same table shows clear losses against the circled competitors: 3.8 Flash trails Claude Opus 5 on Terminal-bench 4.0 at 19.1% versus 51.8%, on OSWorld-2.0 at 59.0% versus 75.4%, and on GDPVal-AA knowledge-work Elo at 1545 versus 1824 .

Google also launched a second model the same day that the post does not mention. Gemini 3.8 Flash Cyber is a security-focused variant that is not publicly available, distributed through the Fairwind Program to government agencies and critical infrastructure operators .
