How to read the chart
Higher means a better score; farther left means cheaper output. Select an icon for details.
The green line uses all models with a score and an output price above zero; filters do not change this reference line.
Free, unpriced, or unscored models are excluded from the log-scale price chart; see the rankings instead.
Scoring method and data sources
Ranked by LMArena Arena score by default, switchable to the Artificial Analysis Intelligence Index; Arena is not an independent coding evaluation. Prices are official API list prices, with OpenRouter quotes shown separately as the lowest route price. Open weights do not mean unrestricted commercial use. Data sources

Not yet ranked by Arena 2
Tracked models that have no LMArena or Artificial Analysis score yet, newest first. They move into the table once scored.
Sources & methodology
As of Oct 16, 2026, 7 models sit on the price–performance frontier: nothing is stronger at the same price. The cheapest frontier model is MiMo-V2.6-Flash ($0.28 per 1M output tokens); the strongest is Claude Opus 5.5 (score 57.6, $20.00 output).
- AGarena.ai Agents
Agents leaderboard: task success rate, 95% interval, sessions and rank (arena.ai Agents, via the public Hugging Face dataset lmarena-ai/leaderboard-dataset, CC BY 4.0). Hugging Face
- LMLMArena
Arena score, 95% confidence interval, votes and rank (overall Text leaderboard with style control, the same view arena.ai shows by default; dataset CC BY 4.0).
- AAArtificial Analysis
Intelligence Index, Coding Index, output speed, TTFT / first-answer latency, release dates and official prices (shown on this page only, not in the public API).
- OROpenRouter
Per-provider prices (the cheapest becomes “lowest route”), context length and listing dates.
- $Vendor pricing pages
“Input / Output” are official API list prices (USD per 1M tokens); when no official price exists we use the OpenRouter price and mark it with *.
How we compute it
- Ranking: by default, the arena.ai Agents task success rate (real users’ coding/tool agent tasks). When a model has several reasoning tiers (Max/High/xHigh), the best-scoring tier is used and labelled; fewer than 10,000 sessions or a 95% half-width above 3 points is marked Preliminary. Models without an agent result follow, ordered by LMArena Text (style control); the Text column is still sortable.
- Rank: by default, LMArena Text Arena score with style control (the same view arena.ai shows by default; Bradley-Terry, not Elo). The ± is the half-width of the 95% confidence interval, and neighbouring ranks often overlap. Models with fewer than 5,000 votes or ± above 10 are marked Preliminary. We do not invent a composite score.
- Intelligence / Coding Index: Artificial Analysis aggregates of public benchmarks. When a model has several reasoning-effort tiers, the table shows the best tier for the current sort column; switch to “by tier” to see each one.
- Prices are USD per 1M tokens. “Lowest route” is the cheapest OpenRouter provider’s input / output price; ⚠ marks routes more than 60% below list (usually promos or a single provider). The best-value board only includes models with Arena ≥ 1400 or Intelligence Index ≥ 40, sorted by official output price.
- Latency and speed: TTFT is the time to the first token (including thinking tokens); “Answer” is the time to the first answer token (includes the thinking phase for reasoning models); speed is output tokens per second. All are Artificial Analysis medians.
- Updates: Text and other data sync daily at 14:20 (UTC+8), the Agents board at 14:25. Agent rank changes appear only after 14 days of daily records; until then no arrows are shown.
- Updates: synced automatically every day at 14:20 (UTC+8). LMArena publishes on its own schedule, so the “Arena published” date can be older than the update date. “This week” compares against the daily archive from 7 days earlier.
- Open data: /api/public/llm-leaderboard.php (JSON, LMArena and OpenRouter fields only).
FAQ
What is the best AI model right now?
As of Oct 16, 2026, the arena.ai Agents leaderboard (success rate on real coding/tool tasks) is led by Claude Opus 5.5 (17.18%, 95% interval 13.80%–20.56%), ahead of GPT-6.1 Sol (14.78%). The top intervals overlap heavily, so the exact order is not reliable. On the LMArena Text leaderboard, Gemini 4 Argon leads (1,523.9).
Which good AI model is the cheapest?
Among models above the quality floor (Arena ≥ 1400 or Intelligence Index ≥ 40), MiMo-V2.6-Flash has the lowest official price: $0.14 input / $0.28 output per 1M tokens, followed by MiMo V2.5 ($0.28 output). See the best-value leaderboard.
What is the best open-source (open-weight) AI model?
By Arena score, the top open-weight model is Kimi K3 (Moonshot AI, 1,487.1), followed by MiMo-V2.6-Pro (1,479.2). We track 21 open-weight models with an Arena score — see the open-weight leaderboard. Open weights do not mean unrestricted commercial use; check each licence.
Which AI model is best for coding?
On the Artificial Analysis Coding Index, Claude Fable 5.1 is highest (81.6), followed by Claude Opus 5 (78.0). The index aggregates coding benchmarks and differs from the Arena score; see the full coding leaderboard.
Which AI model is the fastest?
The fastest measured output speed belongs to K2 Horizon 375B A23B (1021 tokens/s); the lowest time to first answer token belongs to K2 Horizon 375B A23B (3.65 s). These are Artificial Analysis medians; for reasoning models the first-answer latency includes thinking time.
Which AI models were released recently?
5 tracked models were released in the last 14 days, including Muse Spark Open (Oct 15, 2026), Muse Wonder (Oct 12, 2026), Muse Wonder Full (Oct 12, 2026), Claude Haiku 5.5 (Oct 7, 2026). New models usually take a few days to appear on LMArena; until then they are listed under “Not yet ranked on Arena”.
How often is the data updated, and where does it come from?
Synced automatically every day: the Agents board comes from arena.ai (public Hugging Face dataset, current release Oct 14, 2026), Text scores from LMArena (released Oct 15, 2026); intelligence and coding indices, speed and latency from Artificial Analysis; route prices and context from OpenRouter. This page was updated Oct 16, 2026.
Why do prices differ from the official site?
Input/output prices are official list prices in USD per million tokens. The lowest route price is the cheapest OpenRouter route, which may be a promotion or a single provider and can differ from local resellers.
