Google's flagship Gemini launches at half price while its engineers doubt the code
Gemini 4 Argon opens at $2 per million input tokens, level with OpenAI's one-day-old discount and half Google's own list rate, in the week staff with direct access said it falters on real coding work. The discount and the doubt landed together; the rollout decides which one explains the other.

The charge: a frontier at half price
Google unveiled Gemini 4 Argon on 30 September at $2 per million input tokens and $10 per million output, half the $4 and $20 rates that apply once an introductory period Google has not dated runs out 12. The opening price lands exactly on GPT-6.1 Sol, the cost-cut model OpenAI shipped the day before, and a fifth of GPT-6 Astra's input rate 3. Access is gated: Fairwind Program cyber defenders first, paid API customers and AI Ultra subscribers next, no public date 12.
Argon opens level with OpenAI's discount, half its own list rate
- Estimate
Data
| Value | |
|---|---|
| GPT-6 Astra | $10/M input |
| Argon list rate (estimate) | $4/M input |
| Claude Opus 5.5 | $4/M input |
| GPT-6.1 Sol | $2/M input |
| Argon intro | $2/M input |
The exhibits: 13 wins, printed beside the losses
Argon leads 13 of the 19 benchmarks Google published against GPT-6 Astra, Claude Fable 5.1 and Claude Opus 5.5, sweeping knowledge work, long context and vulnerability repair 3. The same table concedes the agent-coding suites: FrontierSWE v2 and Terminal-Bench Science by 10.5 points each to Astra, Terminal-bench 4.0 to Opus 5.5 3. No third party has reproduced a score 3.
The prosecution: the people with access
Staff with direct access say the model does less well when put to real work, faltering on front-end design and messy codebases, and people familiar call it very large and expensive to run. Google answers that calling it weak in coding is "inaccurate" 45. Its predecessor died on the runway: Gemini 3.5 Pro, promised for June, was abandoned, and training runs of that class can cost up to $400 million 4.
The market has priced the doubt already. Alphabet's market value sits close to 20% below its June level 6, the stock rose about 2% after hours on the announcement and then fell 2% on 1 October with BNP Paribas holding a $420 Buy through both moves 67. Over three months GOOGL is down about 6% while Meta, whose free Muse agent passed 5 million downloads, is up 19% 2.
The defense: weeks of testing, thousands of Googlers
Google says employees have tested Gemini 4 for weeks, some with unlimited access 2, and that thousands of Googlers already run Argon on coding, quantum research and data-center tuning that freed 300 TiB of memory 1. DeepMind chief Koray Kavukcuoglu goes further: "In my mind, it's a certainty that we are always gonna be at the frontier" 4.
The verdict watch: whether $4 ever arrives
Either $2 is a promotion or it is a ceiling, and only one of them pays for a $205 billion buildout. Quarterly capex passed operating cash flow in Q2 2026, $44.9 billion against $39.1 billion 8, and guidance of $195 billion to $205 billion doubles 2025's $91.4 billion 89. Watch the undated intro period: if it quietly extends, the doubt set the price.
