Anthropic provides subsidized access to Claude models through Claude Code. It is well understood to be 'a loss leader' so that they can incentivize people to use Claude Code. OpenCode lets people take the Claude-Code-only-API-Key, and lets them use it in a different harness. Anthropic's preferred way for such interaction is getting a different, Claude API key (and not Claude Code SDK API key). --- A rough analogy mig…

> It is well understood to be 'a loss leader' You have zero proof for this claim. It's like people read somewhere that stuff and keep spitting it out again and again without understanding..

This seems like pure misinformation. The code lines that are actually changed: hint: { opencode: "recommended", -anthropic: "API key", openai: "ChatGPT Plus/Pro or API key", }[x.id], They're removing the ability to use OpenCode via Anthropic API key

Is this what the legal request demanded or is this just something that OpenCode is doing out of spite? Seems unclear. To me the meat of this change is that they're removing support for `opencode-anthropic-auth` and the prompt text that allows OpenCode to mimic Claude Code behavior. They have been skirting the intent of the original C&D for awhile now with these auth plugins and prompt text.

I'm really struggling to understand how Anthropic is benefited by not allowing this. Its bad PR for no good reason. The only thing I can figure is that Claude Code is hemorrhaging money, they're too afraid to actually enforce reasonable token limits, and the only thing that's keeping it from totally bankrupting the company tomorrow is: controlling the harness and having the harness dynamically route toward Haiku or S…

also for economic reason. Anthropic design Claude code so they are in control regarding how token get burned. To a degree. With 3rd party, designers have not incentive to be token consumption conscious. Gemini has a 1M token context, flash can be used for free via the web interface, can't paste more than handful thousands token.

Dario has stated multiple times he doesn't believe there is any value in open-weight models. Not surprised. This is not the behavior of an innovative company - it is fear-driven. They are seeing a rapidly shrinking moat.

This exactly. Kimi 2.5 has coding performance hardly discernible from Claude. The only way to maintain a business edge is to crush open source clients to force people into a closed ecosystem. Once there, create context moat where people are not in control of their own context data (cannot export it to open tooling). Maybe we can call it the Oracle play? It’ll be interesting to see if companies get tricked. I think it…
