The 18 LLM leaderboards we'd actually use.

Anthropic's new flagship: 80.3% SWE-bench Pro, 96% SWE-bench Verified on Vals.ai, and 85.0% OSWorld-Verified make it the best production coding pick for non-trivial engineering tasks.

Anthropic's new default agent: 85.2% SWE-bench Verified, 81.2% OSWorld-Verified, 86.6% BrowseComp multi-agent, and 1M context at the same durable $3/$15 as Sonnet 4.6 ($2/$10 intro through 2026-08-31).

Best current BFCL (72.5) with rock-solid JSON-schema adherence and a 1M window at $5 out.

Best open-weights model we've tested: #1 LiveCodeBench (93.5), 80.6 SWE-bench, 1M context, $0.87 out.

The long-context standard — 1M tokens with cheap input that keeps the bill survivable.

$0.22 / 1M out with LiveCodeBench 91.6 and a 1M window — nothing else is this capable this cheap.

Tops Chatbot Arena (1503) and writes paragraphs you'd ship; understands tone notes and edits like a copy chief.

GDPval-AA ELO 1932 and Anthropic-reported finance, trading, and analytics wins make it the strongest general knowledge-work pick; do not use Mythos-only HLE rows as Fable evidence.

1M context plus MMLU-Pro 88.6 at $3 out — handles a 500-page transcript faithfully without breaking the budget.

Highest groundedness and graceful refusal — says "not in the docs" instead of guessing.

Best coverage of lower-resource languages with strong idiom handling and a huge context for document-level consistency.

Best text-to-SQL accuracy in production — HumanEval 94.2 and top-tier reasoning pick the right join and respect dialect quirks.

The current photoreal leader — brand-consistent, with the best text rendering and hands in the open ecosystem.

Best overall video quality in the catalog: 30-second clips, native audio, and up to 4K through Vertex AI.

Most expressive voices with the lowest artifact rate — the studio standard for production VO.

Lowest WER on noisy real-world audio with the broadest language coverage; cheap to self-host.

Most production-ready output; stems are usable and the vocals are believable.

Best inpaint preservation — brand colors and untouched regions stay put across edits.
