UnverifiedOpen-source models still have a perceptible gap compared to the strongest closed-source models on high-difficulty tasks such as handling large codebase contexts, complex multi-file refactoring, and long-chain reasoning.79% similarUnverifiedCompanies such as OpenAI, Anthropic, Google, and Meta continue to release increasingly powerful foundation models, while open-source models like Llama and Mistral have already substantially narrowed the capability gap with commercial models.68% similarUnverifiedThe vast majority of so-called open-source models only release model weights, while keeping training code, data processing pipelines, and training configurations in a black box.68% similarUnverifiedOpenAI's open-sourcing this time has been interpreted by the industry as a response to competitive pressure from open-source models such as DeepSeek and Qwen, which are continuously closing the performance gap with closed-source models.68% similarUnverifiedDevelopers can use tools such as Ollama and LM Studio to run open-source code models (such as DeepSeek Coder and Code Llama) locally as a backup solution; their capability ceiling is below that of top cloud-based models but they are fully controllable.68% similar
