# Devin is now up to 40% more cost-efficient By Steven Van · 2026-09-28 Fusion and Normal mode cost 30-40% less, Ultra 15-20% less and Devin Review up to 70% less, with Fusion scoring 68.8 on FrontierCode 1.1. Devin's per-task cost has dropped across its modes. [Devin]() is now 30-40% cheaper in Fusion and Normal mode, 15-20% cheaper in Ultra, and up to 70% cheaper in Devin Review, according to the [vendor's announcement](). The company says intelligence has been maintained or improved in every mode. ## Where the savings come from Devin attributes the reductions to newer models, including its own SWE-2, and to changes in its Cloud harness. It says it picks models per job: - **Fusion** pairs a capable lead model with a more cost-effective sidekick. - **Devin Review** chooses models for analyzing diffs, finding bugs and categorizing changes. - **Normal and Ultra** choose models for planning, testing, debugging, migrations and similar work. The post describes Opus 5.5 and GPT-6 Sol as stronger and price-performant, GPT-6 Astra as good at computer use, and GPT-6 Luna as substantially cheaper for supporting tasks. ## Harness changes Devin now batches several shell commands into one call and runs independent tool calls in parallel. A model can request formatting, linting and tests together, then reason about the results at once. In the vendor's illustrative example, that takes two turns instead of four and sends 49% fewer tokens. The harness also reuses cached context more. In another illustrative session, caching cut tokens processed from scratch by 71%. The vendor notes that cache reads are getting cheaper: Opus 5.5's cost 60% less than Opus 5's, and GPT-6 Sol and Luna both halve cache-read prices compared with their 5.6 predecessors. ## Benchmark result Devin Fusion scores 68.8 on FrontierCode 1.1 Extended, at an average of $0.60 per task. Devin lists Opus 5.5 (high) at 65.2 and $0.90, Fable 5.1 (medium) at 63.6 and $2.68, GPT-6 Astra (high) at 63.1 and $2.62, SWE-2 (high) at 60.1 and $0.64, and GPT-6 Sol (high) at 59.6 and $0.87.
