Tinted cells mark the best score on each test, including ties.\n\n| Benchmark | Pareto 26.9 | Fable 5.1 | GPT 6 Astra | DeepSeek 4.1 Flash | \n|---|---|---|---|---|\n| DeepSWE | 74 | 67 | 74 | 74 | \n| Terminal-Bench 4.0 | 51 | 56 | 58 | 31 | \n| MMMU-Pro | 78 | 81 | 87 | 77 | \n| HLE (no tools) | 49 | 55 | 54 | 39 | \n| ArXivMath | 88 | 72 | 91 | 28 | \n\nMeasured task costs and a composite score have not been published for this release. Scores do not establish cost per completed task.\n\n## Details and pricing\n\nPareto accepts text and image inputs. Use `pareto` as the model identifier. The published comparison set is Fable 5.1, GPT 6 Astra, and DeepSeek 4.1 Flash.\n\nPer million tokens: $2.50 input, $0.25 cached input, and $7.50 output. Cached input is billed at 0.1 times the input rate. Actual spend depends on token usage and cache hits.\n\n[Get started with Unbiased](https://platform.unbiased.ai/buy?utm_source=unbiased.ai&utm_medium=site&utm_campaign=model_card_final_cta)", "url": "https://wpnews.pro/news/pareto-26-9-model-card", "canonical_source": "https://unbiased.ai/model-card/", "published_at": "2026-09-18 13:39:44+00:00", "updated_at": "2026-09-18 13:56:08.424330+00:00", "lang": "en", "topics": ["ai-products", "large-language-models", "ai-research"], "entities": ["Unbiased", "Pareto 26.9", "Fable 5.1", "GPT 6 Astra", "DeepSeek 4.1 Flash"], "alternates": {"html": "https://wpnews.pro/news/pareto-26-9-model-card", "markdown": "https://wpnews.pro/news/pareto-26-9-model-card.md", "text": "https://wpnews.pro/news/pareto-26-9-model-card.txt", "jsonld": "https://wpnews.pro/news/pareto-26-9-model-card.jsonld"}}
