The author is skeptical, noting that the benchmark used (Draco bench) is narrowly focused on deep research tasks and doesn't reflect general capability. After hands-on testing across coding, simulation, and creative tasks, the author finds Fusion underwhelming — buggy outputs, slow response times, high cost, and limited agent compatibility. The conclusion is that OpenRouter's marketing claims are misleading and that the product doesn't come close to matching the raw capabilities of leading models, particularly for coding. The author suggests OpenRouter should focus on its core strength of model routing rather than positioning itself as an AI lab. ## Full article daily.dev links to this article rather than hosting it.
