Cohere launches open weights model Command A+ that achieves 37 on the Artificial Analysis Intelligence Index

The release of Command A+ places Cohere in line with Claude 4.5 Haiku on the Intelligence Index, and just above NVIDIA Nemotron 3 Super and Gemini 3.1 Flash-Lite.

Key Takeaways:

➤ Command A+ ranks first on AA-Omniscience Non-Hallucination at 86%, ~3 percentage points ahead of the next-best model. Its AA-Omniscience Accuracy is 9%, so the headline AA-Omniscience score lands at -4, demonstrating a similar archetype to Claude 4.5 Haiku, where the model knows its limits

➤ On Cohere’s API, Command A+ (~281 output tokens per second) is faster than several comparable open-weights and small to mid-sized proprietary models (e.g., GPT-5.4 nano, Claude 4.5 Haiku, and Grok 4.3), but still slower than Gemini 3.1 Flash-Lite Preview, which outputs 304 tokens per second

➤ Command A+ trails its peer set on scientific reasoning (HLE ~11%, GPQA Diamond ~76%) and on coding (Terminal-Bench Hard ~25%, SciCode ~38%), consistent with gaps on the hardest science and agentic coding benchmarks

➤ It supports visual reasoning and scores 63% on MMMU-Pro (between Claude 4.5 Haiku at 59% and GPT-5.4 nano (xhigh) at 65%)

In our pre-release testing, Command A+ performed strongly on speed for its intelligence, reaching 281 output tokens per second. This reflects higher intelligence and speed than models such as gpt-oss-120b, but sits behind the new Pareto frontier established by Gemini 3.5 Flash

Amongst comparable models, Command A+ is competitive on intelligence vs. output tokens to run the Artificial Analysis Intelligence Index

On AA-Omniscience, our knowledge and hallucination evaluation, Command A+ fits a positive archetype where it knows its limitations: although it has relative low performance on AA-Omniscience Accuracy, it also hallucinates the least on AA-Omniscience, resulting in a fairly strong relative headline AA-Omniscience score of -4

Artificial Analysis Decision Index v1.0

The Artificial Analysis Decision Index benchmarks decision models, a new category of models that answer structured decisions in a single call with a probability for each option. Version 1.0 combines four evaluations across classification, tool calling, knowledge, hallucination, and reasoning.

Announcing AA-3D: a benchmark for AI models building interactive 3D experiences

AA-3D is a new benchmark of how well AI models build interactive 3D experiences. Each model turns a written brief into a working three.js scene in an offline sandbox, and our recruited panel compares the scenes in blind pairwise votes.

Announcing FrontierCode on Artificial Analysis: can AI models write code maintainers would merge?

Cognition's FrontierCode 1.1 tests whether AI models make code changes that maintainers of real open source repositories would merge. Leading models still fail more than 40% of the time.
