Which is exactly why these companies are now all focused on building products rather than (or alongside) improving their base models. Claude Code, Cowork, Gemini CLI/Antigravity, Codex - all proprietary and don't allow model swapping (or do with heavy restrictions). As models get more and more commoditized the idea is to enforce lock-in at the app level instead.
FWIW, OpenAI Codex is open source and they help other open source projects like OpenCode to integrate their accounts (not just expensive API), unlike Anthropic who blocked it last month and force people to use their closed source CLI.
Gemini CLI is open source too, though I think the consensus is it's a distant third behind Claude Code and Codex
The classic commoditize your complements.
I only integrate with models via MCP. I highly encourage everybody to do the same to preserve the commodity status
