Developer Switches From Claude Code to Codex

Computer scientist Santiago Valdarrama posted that he migrated his work from Claude Code to Codex two weeks ago. He states he performs every previous task without missing features, needed only one day to adjust, and sees no reason to return. Valdarrama adds that he does not care about Fable and does not believe Opus is better than Sol. He concludes that Anthropic products have zero stickiness. In reply, Cerebras founder Andrew Feldman recommends Sol Ultrafast and calls it extremely fast. The exchange centers on the reported ease of the change and the suggestion of an alternative tool.
