This is definitely Barbara Streisanding right now. I had never heard of OpenCode. But I sure have now! Will have to check it out. Doubt I’ll end up immediately canceling Claude Code Max, but we’ll see.

agreed. This is definitely free PR for OpenCode. I didn't try it myself until I heard the kerfuffle around Anthropic enforcing their ToS. It definitely has a much nicer UX than claude-code, so I might give the GPT subscription a shot sometime, given that it's officially supported w/ 3rd party harnesses, and gpt 5.2 doesn't appear to be that far behind Opus (based on what other people say).

Obviously Anthropic are within their rights to do this, but I don’t think their moat is as big as they think it is. I’ve cancelled my max subscription and have gone over to ChatGPT pro, which is now explicitly supporting this use case.

Is opencode that much better than Codex / Claude Code for cli tooling that people are prepared forsake[1] Sonnet 4.5/Opus 4.5 and switch to GPT 5.2-codex ? The moat is Sonnet/Opus not Claude Code it can never be a client side app. Cost arbitrage like this is short lived, until the org changes pricing. For example Anthropic could release say an ultra plan at $500-$1000 with these restrictions removed/relaxed that refl…

The combination of Claude Code and models could be a moat of its own; they are able to use RL to make their agent better - tool descriptions, reasoning patterns, etc.

Are they doing it? No idea, it sounds ridiculously expensive; but they did buy Bun, maybe to facilitate integrating around CC. Cowork, as an example, uses CC almost as an infrastructure layer, and the Claude Agent SDK is basically LiteLLM for your Max subscription - also built on/wrapping the CC app. So who knows, the juice may be worth the RL squeeze if CC is going to be foundational to some enterprise strategy.

Also IMO OpenCode is not better, just different. I’m getting great results with CC, but if I want to use other models like GLM/Qwen (or the new Nvidia stuff) it’s my tool of choice. I am really surprised to see people cancelling their Max subscriptions; it looks performative and I suspect many are not being honest.

I do admit to feeling some schadenfreude over them reacting to their product being leeched by others. I get it though, Anthropic has to protect their investment in their work. They are in a position to do that, whereas most of us are not.

> protect their investment Viewed another way, the preferential pricing they're giving to Claude Code (and only Claude Code) is anticompetitive behavior that may be illegal.

This is a misunderstanding of the regulations.

They’re not obligated to give other companies access to their services at a discounted rate.

This is a misunderstanding of the regulations. They’re not obligated to give other companies access to their services at a discounted rate.

They may however be obligated to not give customers access to their services at a discounted rate either - predatory pricing is at least some of the time and in some jurisdictions illegal.

This is what ACP and https://github.com/zed-industries/claude-code-acp enables. ACP controls agents - there is native support in Copilot CLI and Gemini and adapters for claude code and codex.

wow. ACP is used within zed so I guess zed is safe with ACP using claude code I wonder if Opencode could use ACP protocol as well. ACP seems to be a good abstraction, I should probably learn more about it. Any TLDR's on how it works?

According to Opus, ACP is designed specifically for IDE clients (with coding agent “servers”), and there’s some impedance mismatch here that would need to be resolved for one agent cli to operate as a client. I havent validated this though.

—-

1. ACP Servers Expect IDE-like Clients The ACP server interface in Claude Code is designed for: ∙ Receiving file context from an IDE ∙ Sending back edits, diagnostics, suggestions ∙ Managing a workspace-scoped session It’s not designed for another autonomous agent to connect and say “go solve this problem for me.”

2. No Delegation/Orchestration Semantics in ACP ACP (at least the current spec) handles: ∙ Code completions ∙ Chat interactions scoped to a workspace ∙ Tool invocations It doesn’t have primitives for: ∙ “Here’s a task, go figure it out autonomously” ∙ Spawning sub-agents ∙ Returning when a multi-step task completes

3. Session & Context Ownership Both tools assume they own the agentic loop. If OpenCode connects to Claude Code via ACP, who’s driving? You’d have two agents both trying to: ∙ Decide what tool to call next ∙ Maintain conversation state ∙ Handle user approval flows
