AI Model Power Rankings
Argon finally opens, and Meta turns up at Opus prices. Two weeks after announcing it, Google opened Gemini 4 Argon to paying customers on October 13 at $2 / $10, a price that doubles in December. A day earlier, Meta launched Muse Wonder, its first frontier model, at exactly Claude Opus 5.5's price, then released the weights of an 816-billion-parameter Muse Spark Open on Wednesday. Opus 5.5 keeps #1: it still leads the independent Artificial Analysis index and Arena's WebDev board.
Up to #2 now that you can actually buy it. It still leads Arena's text board, and Artificial Analysis has it level with GPT-6 Astra at a fraction of Astra's price, with the lowest hallucination rate of any top model.
Down to #7. Argon now matches it on the Artificial Analysis index for $2 / $10 against Astra's $10 / $50, and OpenAI's own GPT-6.1 Sol covers most of its coding. It's hard to recommend at the price.
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 Still top of the Artificial Analysis index at 58 and #1 on Arena WebDev. Two new rivals arrived this week, and neither beat it. |
$4 in / $20 out | 97 |
| 2 | ▲1 | Gemini 4 ArgonGoogle Finally on sale, and still #1 with Arena text voters. Book it at $4 / $20 in your budget, though, because that's the price from December 1. |
$2 in / $10 out | 95 |
| 3 | ▼1 | Claude Sonnet 5.5Anthropic Scores 56 on the Artificial Analysis index, ahead of Argon's 53 at the same $2 / $10. Pushed to #3 only by Argon's text-board lead. |
$2 in / $10 out | 94 |
| 4 | — | GPT-6.1 SolOpenAI A quiet week. Still the default in Codex and the best value in OpenAI's lineup. |
$2 in / $10 out | 93 |
| 5 | NEW | Muse WonderMeta Meta's first frontier model debuts at #2 on Arena text. It costs as much as Opus 5.5 and scores six points lower on the Artificial Analysis index, so it isn't the better buy. |
$4 in / $20 out | 91 |
| 6 | ▼1 | Claude Fable 5.1Anthropic Still superb on the hardest problems, but at 2.5x Opus 5.5's price it's a specialist pick now. |
$10 in / $50 out | 90 |
| 7 | ▼1 | GPT-6 AstraOpenAI Argon now matches it on the Artificial Analysis index for a fifth of the list price. Keep it for long automation jobs, where it still leads. |
$10 in / $50 out | 88 |
| 8 | — | Claude Haiku 5.5Anthropic Its second week keeps it as the best of the $0.10 models. Nothing new arrived to challenge it. |
$0.1 in / $0.5 out | 88 |
| 9 | ▼2 | Gemini 3.8 FlashGoogle Still a text top-10 model at Flash prices, but the January price doubling is getting closer. |
$0.75 in / $3.75 out | 87 |
| 10 | — | Kimi K3Moonshot AI Still the strongest model from outside the US labs, and still ahead of Meta's new open model on the Artificial Analysis index. |
Not published | 85 |
| 11 | — | GLM-5.3Z.ai · open Muse Spark Open arrived to challenge it and fell short on general smarts and coding. Still the open-weight model to beat. |
Not published | 84 |
| 12 | ▼3 | Muse Spark 1.3Meta Meta's own Muse Wonder now takes the spotlight. It's still decent value, and it actually edges Wonder on WebDev. |
$1.25 in / $4.25 out | 83 |
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. Meta's own launch table has it well ahead of Muse Wonder on ProgramBench, 70.5 to 50.0. |
$4 in / $20 out | 98 |
| 2 | — | Claude Sonnet 5.5Anthropic Top four on WebDev at half Opus 5.5's price. The pick for well-scoped fixes. |
$2 in / $10 out | 94 |
| 3 | — | GPT-6.1 SolOpenAI The default in Codex. Most of Astra's coding for a fifth of the price. |
$2 in / $10 out | 93 |
| 4 | — | GPT-6 AstraOpenAI Still #2 on WebDev, but Sol does most of the same work for much less. |
$10 in / $50 out | 91 |
| 5 | — | Claude Fable 5.1Anthropic Excellent code, but two cheaper Anthropic models do most jobs as well. |
$10 in / $50 out | 90 |
| 6 | — | Gemini 4 ArgonGoogle Now you can test it yourself. Still outside the WebDev top five, and Bloomberg reports it does worse on some practical coding jobs than its benchmarks suggest. |
$2 in / $10 out | 88 |
| 7 | NEW | Muse WonderMeta #15 on WebDev and #12 in Arena's agent rankings. A solid debut, but not one to switch your coding agent for at $4 / $20. |
$4 in / $20 out | 85 |
| 8 | ▼1 | Kimi K3Moonshot AI Still a popular pick for cheap coding agents. |
Not published | 84 |
| 9 | ▼1 | GLM-5.3Z.ai · open The open-weight coding pick. On Meta's own table it beats Muse Spark Open on Terminal-Bench. |
Not published | 83 |
| 10 | ▼1 | Claude Haiku 5.5Anthropic Independent Terminal-Bench runs land in the mid-30s. That's plenty for cheap sub-agents. |
$0.1 in / $0.5 out | 81 |
