compare_models

Head-to-head comparison of two models with BenchLeader's verdict: who leads on quality (a lead is claimed only outside the combined margin of error), price and speed ratios, category-by-category wins, when to choose each, and shared benchmark results. Links the comparison page.

get_benchmark

get_leaderboard

The BenchLeader Index leaderboard of large language models: a daily composite of independent public benchmarks, one row per model (its best reasoning-effort configuration) as on the homepage. Optionally rank by one category score (coding, agentic, reasoning, math, knowledge…), list every model × effort configuration, or filter to open-weights models or one developer. Paged.

read-only

Argument	Type	Description
limit	integer	How many rows to return (at most 100).
offset	integer	Rows to skip, for paging (use next_offset from the previous page).
category	string	Rank by this category score instead of the overall Index, e.g. coding, agentic, reasoning, math, knowledge, instruction, multimodal, long_context.
developer	string	Only models from this developer, e.g. OpenAI, Anthropic, Google, DeepSeek.
configurations	boolean	List every ranked model × reasoning-effort configuration rather than one row per model.
open_weights_only	boolean	Only models with downloadable weights.

get_model

One model's BenchLeader profile: Index and rank, category scores, list price, speed, latency, context window, its other reasoning-effort configurations, and its strongest independent benchmark results (each with its board rank, publisher and source link).

Argument	Type	Description
model*	string	Model id ("claude-opus-5-5"), configuration id ("gpt-6-astra@max"), page URL or name.
effort	string	Reasoning-effort configuration to show (none, low, medium, high, xhigh, max…). Defaults to the best-ranked one.
results_limit	integer	How many benchmark results to return (at most 50).
