The choice of AI coding assistants in mid-2026 hinges less on benchmark scores and more on practical factors like payment methods, usage limits, and vendor policies. While models like GPT-5.5 and Anthropic's Opus 4.6 show performance differences in benchmarks, third-party harnesses built on these models often achieve higher scores. Practical concerns such as sudden quota exhaustion, API rate limits, and vendor-imposed restrictions, like Anthropic's blocking of OAuth tokens for third-party tools, significantly impact developer workflows and deadlines.
