EDITOR VERDICT

Argon has moved from a restricted watchlist to a public paid pilot candidate. Confirm your route, budget at December rates and test recovery and retention before enabling long decode. Fairwind's cyber route remains a separate admission programme.

WHAT IT IS

Gemini 4 Argon, explained.

Google announced paid Gemini API availability for Gemini 4 Argon on 13 October 2026, alongside Gemini app access for Google AI Pro and Ultra subscribers. AI Studio and Antigravity have separate plan requirements. Fairwind remains a separate approved cyber-access programme; it is not the only route to Argon. Choose the exact account and execution surface before comparing costs or enabling tools.

PROOF TESTRequired before scale

Confirm the exact account and model, December rates, implicit caching and unified context. Test interrupted execution, cancellation, storage and full billed usage before a long-running pilot.

INDEPENDENT TEST PENDING

No launch-day score.

HubAI will publish a score only after the same representative tasks have been run against current alternatives. Vendor benchmarks are not treated as an editorial rating.

STRENGTHS

What earns its shortlist place.

+01

Public paid API identity and dated rate schedule

Why it matters: provides a route to request access, subject to approval.

+02

Documented implicit caching and long-decode protocol

Why it matters: helps model temporary and later cost scenarios.

+03

App and developer routes now have explicit plan boundaries

Why it matters: makes participant obligations inspectable before a pilot.

LIMITATIONS

What can break the business case.

−01

Introductory standard token prices double after November

Buyer impact: prevents treating the model as generally available today.

−02

Long decode shares context and can require stored background execution

Buyer impact: requires a controlled independent pilot before a performance verdict.

−03

Supplier capability claims remain independently untested by HubAI

Buyer impact: leaves integration and budget assumptions unresolved.

Cost reality

The subscription price is only the starting point. HubAI evaluates usage limits, failed attempts and the work needed to produce one usable result. Pricing changes frequently, so the structure and verification date matter more than a headline price.

PRICING DECODER

Budget for the result, not the plan badge.

Published structure: Standard API, USD per million tokens: $2 input/$10 output through 30 November 2026; $4/$20 from 1 December. Implicit cached input $0.10, then $0.20. Tools and retries add cost. · Recorded check: 14 October 2026. USD list price; UK price/VAT to confirm.
Free or trial route: Paid Gemini API; Gemini app and AI Mode through AI Pro/Ultra, Antigravity through AI Ultra. No free API tier. Global rollout announced; verify the exact UK account, surface and regional terms.
Primary cost driver: applicable price stage, tokens, tools, sandboxing, retries and human review
Budget test: Record the total cost, attempts and human correction needed to produce ten accepted results.

Pricing checked for editorial use on 14 October 2026. Confirm live price, VAT, region, usage rights and cancellation terms with the vendor before purchase.
