AI Model Power Rankings
Google's Argon takes the text crown, but Opus 5.5 keeps ours. Three new models, all at $2 / $10 per million tokens. Gemini 4 Argon went straight to #1 on LMArena's text board, though almost nobody can use it yet. Claude Sonnet 5.5 and GPT-6.1 Sol both landed in the WebDev top five. And OpenAI shelved GPT-6.1 Astra after it failed its own safety tests. Opus 5.5 holds #1 here: still top for coding, and you can actually buy it.
Debuts at #2. It outscores Fable 5.1 and GPT-6 Astra on Artificial Analysis's index and lands in the Arena WebDev top four, all at half Opus 5.5's price.
Down four places. Anthropic's own Sonnet 5.5 now scores higher on the independent index for a fifth of the price, which leaves Fable a hard sell outside the most demanding agent work.
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 #1 on Arena WebDev and well ahead on SWE-Bench Pro. Argon took the text board, but Opus 5.5 is the best model you can actually use today. |
$4 in / $20 out | 97 |
| 2 | NEW | Claude Sonnet 5.5Anthropic Scores 56 on Artificial Analysis's index, above Fable 5.1 and GPT-6 Astra, at $2 / $10. For most people it is the new sensible default. |
$2 in / $10 out | 95 |
| 3 | NEW | Gemini 4 ArgonGoogle #1 on Arena's text board and the lowest hallucination rate tested. It would rank higher if you could use it; for now, almost nobody can. |
$2 in / $10 out | 94 |
| 4 | NEW | GPT-6.1 SolOpenAI Replaces GPT-6 Sol a week after launch. OpenAI says it nearly matches Astra on coding for a fifth of the price, and Arena's WebDev voters put it in the top five. |
$2 in / $10 out | 93 |
| 5 | ▼2 | GPT-6 AstraOpenAI Powers OpenAI's new Dots agents, but its 6.1 upgrade was shelved and the cheaper Sol now matches it on most coding tests. |
$10 in / $50 out | 91 |
| 6 | ▼4 | Claude Fable 5.1Anthropic Still excellent, but Sonnet 5.5 beats it on the independent index at a fifth of the price. |
$10 in / $50 out | 91 |
| 7 | ▼2 | Gemini 3.8 FlashGoogle Still a top-tier fast model at 75 cents in. The price doubles on January 1. |
$0.75 in / $3.75 out | 89 |
| 8 | ▼2 | Muse Spark 1.3Meta Good conversationalist at a fair price. Three new $2 / $10 models above it make it look less special. |
$1.25 in / $4.25 out | 87 |
| 9 | ▼1 | Kimi K3Moonshot AI Still the strongest model from outside the US frontier labs, but this week's launches widened the gap. |
Not published | 85 |
| 10 | — | GLM-5.3Z.ai · open The best-proven open-weight model. A Flash version is reportedly out, but we haven't seen independent results. |
Not published | 84 |
| 11 | ▼2 | Grok 4.7xAI Good value, and xAI's agent products are growing. The model itself is a step behind the frontier. |
$2 in / $6 out | 83 |
| 12 | ▼1 | GPT-6 LunaOpenAI Very cheap and fast. We still want independent coding numbers before moving it up. |
$0.1 in / $0.5 out | 82 |

| # | Movement± | Model | Price / 1M tokens | Score |
|---|---|---|---|---|
| 1 | — | Claude Opus 5.5Anthropic Holds #1 on Arena WebDev and leads SWE-Bench Pro clearly over Sonnet 5.5. Still the default for serious coding. |
$4 in / $20 out | 98 |
| 2 | NEW | Claude Sonnet 5.5Anthropic Arena WebDev top four on debut, and it beats Opus 5.5 on Terminal-Bench 4.0 in both Anthropic's and Artificial Analysis's runs. Results vary by harness, though. |
$2 in / $10 out | 94 |
| 3 | NEW | GPT-6.1 SolOpenAI The new default in Codex, with an Ultrafast option. OpenAI says it matches Astra on DeepSWE at about a fifth of the cost per task. |
$2 in / $10 out | 93 |
| 4 | ▼2 | GPT-6 AstraOpenAI Still strong at driving a terminal, but Sol 6.1 now does most of the same work for much less. |
$10 in / $50 out | 92 |
| 5 | ▼2 | Claude Fable 5.1Anthropic Excellent code, but two cheaper Anthropic models are now at least as good for most jobs. |
$10 in / $50 out | 90 |
| 6 | NEW | Gemini 4 ArgonGoogle Google claims 77.9% on DeepSWE, but it's only #8 on Arena WebDev, and you can't use it yet. |
$2 in / $10 out | 88 |
| 7 | ▼2 | Kimi K3Moonshot AI Still a popular pick for cheap coding agents. |
Not published | 84 |
| 8 | ▼2 | GLM-5.3Z.ai · open The open-weight coding pick, level with MiMo-V2.6-Pro on WebDev. |

| 9 | ▼2 | Gemini 3.8 FlashGoogle Fine for quick edits and autocomplete-style work. Not the one to run an agent on. |
$0.75 in / $3.75 out | 81 |
