By task type
Overall
What this benchmark measures: 225 code-editing tasks from Exercism across C++, Go, Java, JavaScript, Python, and Rust.
Context: Aider, the edit format, reasoning budget, and two attempts are part of the result.
Scale: 0% - 100%
Accuracy
What this benchmark measures: 65 scientific coding problems with 338 subproblems across 16 research fields.
Context: Zero Shot, Tool Calling, and HAL Generalist are not directly comparable scaffolds.

Scale: 0% - 100%
Accuracy
What this benchmark measures: 102 expert-validated tasks for data-driven scientific work.
Context: The scaffold, tools, and code execution are part of the result. HAL reports both 42 and 44 underlying publications in different places.
Scale: 0% - 100%
Accuracy
What this benchmark measures: A random, fully human-validated subset of 50 GitHub issues from 12 Python repositories.
Context: The small subset is cheaper but statistically less stable than the full 500 tasks. SWE-Agent and HAL Generalist remain separate.
Note (o3): HAL reports min-max ranges for repeated runs. The central value is the reported mean, not a 95% confidence interval.

Accuracy
What this benchmark measures: 307 algorithmic programming tasks from Bronze through Platinum with exhaustive tests.
Context: The benchmark measures competitive programming, not repository navigation, maintainability, or product experience.
Scale: 0% - 100%
Accuracy
What this benchmark measures: 33 automatically verifiable HAL tasks drawn from 214 realistic, time-consuming web research tasks.
Context: The published HAL subset is smaller than the full dataset. Reported costs do not account for caching benefits.
Scale: 0% - 100%
Accuracy
What this benchmark measures: 300 verified tasks across 136 dynamic live websites.
Context: SeeAct and Browser-Use are different agent scaffolds and therefore remain separate comparison cohorts.

50% time horizon
What this benchmark measures: Human task duration at which a model-agent system reaches a 50% or 80% predicted success probability.
Context: Minutes refer to human task duration, not model runtime. METR considers estimates above 16 hours unreliable.
Scale: 0 minutes - 384.15 minutes
80% time horizon

Context: Minutes refer to human task duration, not model runtime. METR considers estimates above 16 hours unreliable.
Scale: 0 minutes - 89.8 minutes

Task origin (Simon Willison)Profile
Published information about this model. Existing estimates are explicitly labeled.
Dated documentation and model-card observations. Provider limits, native context and extended context can differ. Configuration notes retain the source wording.
Pricing
Prices apply to the stated unit. Resolution, output length, and provider can change the cost.
Cost example
$0.6
100 requests with 1,000 input and 500 output tokens each calculate to $0.6. Input accounts for $0.2; output accounts for $0.4.
The calculation uses documented token prices and no cache discount. It excludes extra tools, tax, reasoning tokens, and further hidden output tokens.
