Gemini 4 Carbon
Google DeepMind's most capable Gemini 4 model, announced 28 October 2026 for partners in Google's Fairwind cyber-defence programme and now listed on Google's Gemini API pricing page for paid developers; not available on the free tier. The $2 input / $10 output per million tokens price is introductory and runs until 30 November 2026; from 1 December 2026 it doubles to $4 / $20, the same schedule as Gemini 4 Argon. Thinking tokens are billed as output; cached input $0.10 (then $0.20). Google describes it as built for complex software engineering, maths and science, autonomous agents and long generation of up to 1M tokens. Google and early third-party reports put it ahead on most of the benchmarks Google published, including 59 on the Artificial Analysis Intelligence Index v5 (Claude Opus 5.5: 58, GPT-6 Astra: 57); vendor-reported or early. Prices checked 13 November 2026. Arena text score 1528 (Gemini 4 Carbon (High), 4,403 votes, still preliminary), leaderboard of 27 October 2026.

Gemini 4 Argon
Google's first Gemini 4 model, announced 30 September 2026 for partners in its Fairwind cyber-defence programme and opened to paid Gemini API developers and Google AI Pro and Ultra subscribers on 13 October 2026. Not available on the free API tier. The $2 input / $10 output per million tokens price is introductory and runs until 30 November 2026; from 1 December 2026 it doubles to $4 / $20. Thinking tokens are billed as output; cached input is $0.10 (then $0.20). It has a 1M-token context shared by input, thinking and output, with long generation of up to 1M tokens. Since 12 November the cheaper Gemini 4 Hydrogen slightly outscores it on Google's own Artificial Analysis comparison. Prices checked 13 November 2026.

Claude Opus 5.5
Anthropic
Anthropic's new default flagship, released 22 September 2026, priced 20% below Opus 5 at $4/$20 with cache reads down 60% to $0.20 per million. 1M-token context, 128K output as standard and 300K behind a beta header. Tops Terminal-Bench 4.0 at 66.4% and CursorBench 4.0 at 57.8%, trails GPT-6 Astra on AutomationBench and Terminal-Bench Science; Anthropic notes the margins sit close to the noise. The advertised 40% cost saving compares Opus 5.5 at its default medium effort against Opus 5 at high, and at the same effort it thinks more per turn. Ships four breaking API changes, including thinking that cannot be disabled and a new computer-use toolset. Prices checked 23 September 2026.

Cache writes $12.50 for five minutes, $20.00 for an hour. 1M-token context, up to 128K tokens per answer. Prices checked 1 September 2026. Succeeded by Claude Fable 5.2 on 9 November 2026.
