# What is the best AI model right now? (October 2026)

Canonical: https://theagenticweekly.com/what-is/best-ai-model-right-now · Last verified: 2026-10-27 · Published: 2026-10-27 · Author: Agentic Weekly (operated independently from Texas, US) · Evidence: Evidence: Reported. Leaderboard positions are third-party snapshots (LMArena) and vendor prices are from our model records read from the sources listed below on 2026-10-27 (America/Chicago). We did not run these products or models for this page; picks are labelled by what each leaderboard measures.

> There is no single best AI model, and we do not name one. If you need one name: Claude Opus 5.5 is the only model in the top two of both LMArena Text (Oct 8, 2026) and LMArena WebDev (Oct 22, 2026), at $4 / $20 per 1M tokens. Gemini 4 Argon leads Text chat preference but its score was marked preliminary. These are crowd-vote preferences, not our tests.

Method: Picks come from third-party leaderboard snapshots (LMArena Text and WebDev, dates in the table) matched to our model records; we name no pick where we have no verified leaderboard. Each fact is copied from the vendor page linked in its row into our model records with the date we read it. Reported means read from that page, not run by us; Tested would mean we ran it and logged a dated run, and no model on this page is Tested. 64 language models are in our data: 41 have a sourced USD list price, 2 are priced in another currency and 21 have no verified price. Only models with a sourced price are listed; we do not estimate or pad.

## Our pick by task, with the basis for each

Each row says what the pick is based on and how it could be wrong. Where we have no leaderboard we trust, we name no pick.

Table: Best AI model by task from our data

| Task | Our pick | Next | Based on | Caveat |
|---|---|---|---|---|
| Coding | [Claude Opus 5.5](https://theagenticweekly.com/models/claude-opus-5-5) | [GPT-6 Astra](https://theagenticweekly.com/models/gpt-6-astra), [Claude Sonnet 5.5](https://theagenticweekly.com/models/claude-sonnet-5-5) | [LMArena WebDev](https://arena.ai/leaderboard/webdev) | Human-preference voting on web development tasks, not our own test and not a measure of cost. Vendor claims are listed separately on each model page. |
| General chat preference | [Gemini 4 Argon](https://theagenticweekly.com/models/gemini-4-argon) | [Claude Opus 5.5](https://theagenticweekly.com/models/claude-opus-5-5) | [LMArena Text Arena](https://arena.ai/leaderboard/text) | Its score was marked preliminary on that snapshot, and the leaderboard changes daily. Preference voting is not a measure of accuracy. |
| Open weights | [DeepSeek-V4.1-Flash-1017](https://theagenticweekly.com/models/deepseek-v4-1-flash-1017) | [Kimi K3](https://theagenticweekly.com/models/kimi-k3), [GLM-5.3](https://theagenticweekly.com/models/glm-5-3) | [LMArena WebDev](https://arena.ai/leaderboard/webdev) | Coding-task preference only. Licences differ: DeepSeek-V4.1-Flash is MIT; Kimi K3 and GLM-5.3 add commercial conditions. |
| Run on one machine | [Qwen3.8-27B](https://theagenticweekly.com/models/qwen3-8-27b) | [Gemma 4](https://theagenticweekly.com/models/gemma-4) | [LMArena WebDev](https://arena.ai/leaderboard/webdev) | Qwen3.8-27B ranked #32 and Gemma 4 31B #113 on that board. Hardware needs depend on quantization; we did not run either model. |
| Image generation | [GPT-Image-2.5 Sunburst](https://theagenticweekly.com/models/gpt-image-2-5-sunburst) | [Nano Banana 2.1](https://theagenticweekly.com/models/nano-banana-2-1) | [LMArena Text-to-Image](https://arena.ai/leaderboard/text-to-image) | Preliminary score.

That is a vendor claim, not a ranking. |
| Voice | No single pick | [GPT-Live 1](https://theagenticweekly.com/models/gpt-live-1), [Gemini 3.8 Live](https://theagenticweekly.com/models/gemini-3-8-live) | No leaderboard we verified | We list the newest voice models with their prices only. |
