Week 45, 2026Published October 29, 2026
AI Model Power Rankings
Carbon tops every scoreboard, but you can't use it yet. Opus 5.5 holds #1. Google's Gemini 4 Carbon went straight to #1 on Arena text and on Artificial Analysis's new index on October 28. Only selected cyber defenders can use it, so Claude Opus 5.5 keeps our top spot until Carbon goes on sale. The bigger shake-up was the index itself: version 5 leans on private tests, lifts OpenAI's models and cuts open-weight scores by double digits. Also this week: Mistral Large 4's weights finally arrived, and OpenAI's GPT-6.1 Terra brings a $1 / $5 mid-tier model.
Up from #7 to #3 in the Power Rankings. Artificial Analysis's new v5 index puts it at 57, a point behind Opus 5.5 and ahead of Sonnet 5.5 and Argon. The model didn't change, but a tougher test that relies more on private data shows it much nearer the top than the old one did.
Down from #2 to #6. It drops to 50 on the v5 index, loses Arena's text #1 to its own sibling, and its $2 / $10 introductory price ends on November 30.
01Power Rankings
The best general-purpose AI models right now, with quality, price and momentum rolled into one score.
| # | Movement± | Model | Price / 1M tokens | Score |
|---|---|---|---|---|
| 1 | — | Claude Opus 5.5Anthropic No longer top of either scoreboard: 58 on the v5 index and #3 on Arena text. But it's still #1 on Arena WebDev, and unlike Carbon you can actually use it. |
$4 in / $20 out | 96 |
| 2 | NEW | Gemini 4 CarbonGoogle New. #1 on Arena text and #1 on the v5 index, one point clear of Opus 5.5. It would be our #1 if you could buy it. For now, only Google's selected cyber defenders can. |
$2 in / $10 out | 95 |
| 3 | ▲4 | GPT-6 AstraOpenAI Up four places. 57 on the v5 index, its best showing against Anthropic yet. Still #2 on Arena WebDev. |
$10 in / $50 out | 93 |
| 4 | — | GPT-6.1 SolOpenAI 55 on the v5 index puts it ahead of Sonnet 5.5 at the same $2 / $10. Still the best value in OpenAI's lineup. |
$2 in / $10 out | 93 |
| 5 | ▼2 | Claude Sonnet 5.5Anthropic Slips from 56 to 54 under v5 and now trails Sol. Still top four on Arena WebDev at half Opus 5.5's price. |
$2 in / $10 out | 92 |
| 6 | ▼4 | Gemini 4 ArgonGoogle #2 on Arena text at 1520, but 50 on the v5 index puts it level with Muse Wonder. Budget for $4 / $20 from December 1. |
$2 in / $10 out | 91 |
| 7 | ▼1 | Claude Fable 5.1Anthropic #5 on Arena text. Still a specialist pick at 2.5x Opus 5.5's price. |
$10 in / $50 out | 90 |
| 8 | ▼3 | Muse WonderMeta #4 on Arena text at 1507, but one of the big losers under v5: Wonder Full fell from 56 to 50. |
$4 in / $20 out | 89 |
| 9 | NEW | Kimi K3.1 ProMoonshot AI New. 46 on the v5 index at $2 / $10, the best of any model outside the big US labs. It uses lots of tokens, so real costs run above the list price. |
$2 in / $10 out | 88 |
| 10 | ▼2 | Claude Haiku 5.5Anthropic Still the cheapest strong small model at $0.10 / $0.50. We haven't seen a confirmed v5 score yet. |
$0.1 in / $0.5 out | 87 |
| 11 | NEW | GPT-6.1 TerraOpenAI New. A $1 / $5 model built for computer use. OpenAI's 'matches Astra' claim isn't backed by independent scores, which put it below Sol. |
$1 in / $5 out | 86 |
| 12 | ▼2 | DeepSeek V4.1 FlashDeepSeek · open Dropped from 45 to 32 under v5. The model didn't change, but the gap to the closed frontier looks much wider than it did a week ago. |
$0.3 in / $1.20 out | 84 |
02Coding
For developers and 'vibe coders': writing, fixing and shipping real software.
| # | Movement± | Model | Price / 1M tokens | Score |
|---|---|---|---|---|
| 1 | — | Claude Opus 5.5Anthropic Still #1 on Arena WebDev, around 1810. Carbon debuted at #4, so the coding crown stays with Anthropic. |
$4 in / $20 out | 98 |
| 2 | — | Claude Sonnet 5.5Anthropic Level with Astra in the WebDev top four at a fifth of Astra's price. Still the pick for well-scoped fixes. |
$2 in / $10 out | 94 |
| 3 | — | GPT-6.1 SolOpenAI Still the Codex default and the most coding per dollar from OpenAI. |
$2 in / $10 out | 93 |
| 4 | — | GPT-6 AstraOpenAI Still #2 on WebDev and gaining on the v5 index, but Sol does most of the same work for a fifth of the price. |
$10 in / $50 out | 92 |
| 5 | NEW | Gemini 4 CarbonGoogle New. #4 on WebDev and strong on Google's security-coding tests, but those ran without guardrails and nobody outside Fairwind can check them yet. |
$2 in / $10 out | 90 |
| 6 | ▼1 | Claude Fable 5.1Anthropic Excellent code, but two cheaper Anthropic models do most jobs as well. |
$10 in / $50 out | 90 |
| 7 | ▼1 | Gemini 4 ArgonGoogle Outside the WebDev top five, and now overshadowed by Carbon. |
$2 in / $10 out | 87 |
| 8 | NEW | Kimi K3.1 ProMoonshot AI New. #9 on WebDev and a clear step up on Kimi K3, but heavy context use makes long agent runs expensive. |
$2 in / $10 out | 86 |
| 9 | ▼2 | Muse WonderMeta Still mid-table on WebDev at Opus 5.5's price. |
$4 in / $20 out | 85 |
| 10 | NEW | GPT-6.1 TerraOpenAI New in Codex. Aimed at computer use and office work rather than heavy coding. Use Sol for that. |
$1 in / $5 out | 84 |
| 11 | ▼2 | GLM-5.3Z.ai · open Still a solid open-weight coding model, now joint top of the released open models on v5 with DeepSeek. |
Not published | 82 |
| 12 | ▼2 | Claude Haiku 5.5Anthropic Plenty for cheap sub-agents and simple fixes. |
$0.1 in / $0.5 out | 81 |

$0.1 in / $0.5 out | 95 |
| 2 | NEW | GPT-6.1 TerraOpenAI New. $1 / $5 for a model that sits between Luna and Sol. Artificial Analysis found its low-effort setting very cheap per task. |
$1 in / $5 out | 92 |
| 3 | ▲1 | GPT-6.1 SolOpenAI 55 on the v5 index at $2 / $10, with cached input at $0.10. The strongest model at that price on the new index. |
$2 in / $10 out | 92 |
| 4 | ▼2 | DeepSeek V4.1 FlashDeepSeek · open Down to 32 on v5, but still very cheap: $0.30 / $1.20 at peak and half that off-peak. |
$0.3 in / $1.20 out | 90 |
| 5 | ▼2 | Gemini 4 ArgonGoogle $2 / $10 for one more month, then $4 / $20. At 50 on v5 it now trails Sol at the same price. |
$2 in / $10 out | 88 |
| 6 | — | Claude Sonnet 5.5Anthropic 54 on v5 at $2 / $10, but it uses lots of tokens, which eats into the savings. |
$2 in / $10 out | 88 |
| 7 | NEW | Mistral Large 4Mistral AI · open New. $1.36 / $4.18 now the launch sale is over, with downloadable weights if you'd rather host it yourself. |
$1.36 in / $4.18 out | 86 |

$0.15 in / $0.6 out | 85 |
| 9 | ▼4 | Gemini 3.8 FlashGoogle Still good, still expensive per task next to the Chinese Flash models, and its price doubles in January. |
$0.75 in / $3.75 out | 85 |
| 10 | ▼2 | GPT-6 LunaOpenAI Same price as Haiku 5.5 with weaker independent results. Terra is now the better OpenAI pick if you can pay ten times more. |
$0.1 in / $0.5 out | 84 |
| 11 | ▼2 | Muse Spark 1.3Meta Strong conversation at $1.25 / $4.25, though Terra now competes at a similar price. |
