Arena's Agent board gives ranks only, so the models it ranks come first, by rank, and the apps and tools we score on our checklist follow.

New to this? What the scores and labels mean
- 0 to 100
- Our score for one job, like writing or coding, compared with everything else out today. 100 is the best available today. For AI models we build it from public data, such as Arena's blind votes and Epoch AI's independent tests; apps and tools are scored on our own checklist. The same tool can score differently for different jobs, and where two likely ranges overlap, we call it a tie.
- Our verdict
- Use it: a top choice for most people. Worth trying: good, and worth a go. Depends: good for some people or one kind of job. Wait: too early to tell, or not out for everyone yet. Skip: something else does the job better.
- First look
- Just released. We say what it is and whether to bother, and give it a score once public results exist.
- No score yet
- None of the public sources we use covers it yet, or the only evidence is from a source whose numbers we can't use, so we describe it in words instead.
- Best buy
- Nothing cheaper scores as well for that job.
- Best free
- The best score for that job that costs nothing, through a free plan or by running on your own computer.
- Pay as you go
- No monthly plan: you pay for each use, usually through a developer account.
- Checked
- The day we last confirmed the score and the price against the sources. Prices change often, so check the date.
- AI model
- The engine underneath, like GPT or Claude. You use it through an app or, if you code, directly.
- Open source
- Free to download and run on your own computer, so nothing leaves your machine.

Read our full take
That board publishes ranks rather than ratings, so this job shows ranks, not scores. GPT-6.1 Sol costs $0.57 per arena.ai Agent task against $1.61 for Opus 5.5, so it is where we would start, though its rank has a wide spread and could slip. For the lowest cost, MiMo-V2.6-Pro ranks 13th at about $0.10 per Agent task, with open MIT weights. Among the apps, ChatGPT on Plus and Claude on Pro both score 70 on our checklist at $20/month. Claude Fable 5.1 is not worth its price, since Opus 5.5 ranks above it and Fable costs about four times as much per Agent task.
Our opinion, checked 11 Oct. The picks come straight from the scores below. How we score
This take recommends a product made by Anthropic, whose Claude models help draft our reviews. It also names the best pick from another maker.
Everything we cover for this job, best score first. Scores whose ranges overlap are tied, so choose on price and fit.

Score against cost
Up is a better score, left is cheaper. Plans are the cheapest that unlock the scored feature. 1 without a monthly price is left off; see Pay per use.

Names in one box share a score band and a price step; each shows its own score, best first.
Best value: ChatGPT (GPT-6) (70, $20/mo) · Claude (70, $20/mo)
Show as a table
| Name | Score | Cheapest plan | Price step | Best value |
|---|---|---|---|---|
| ChatGPT (GPT-6) | 70 | $20 a month | $10 to $29 | Yes |
| Claude | 70 | $20 a month | $10 to $29 | Yes |
| Gemini app | 50 | $19.99 a month | $10 to $29 |
Up is a better score, left is cheaper to run. Cost to run one typical agent task (arena.ai, middle of the range), for the 10 scored here that have one; the others are left off rather than mixed with figures from another test.
