abacus: some model names are incorrect & raw output in chat

[balaclava-guy]

Description

Some abacus-provided models (those with / in the slug?) are not working. I confirmed this by creating a separate model entry in opencode.json with the corrected model name:

.

The models are also outputting their commands instead of executing them, tested with deepseek and claude opus:

For reference here is a full list of the canonical names for the models abacus provides from the API page.

This issue might be a duplicate of existing issues. Please check:

• #6836: Providers: Abacus connectivity error - related to Abacus provider issues
• #6615: DeepSeek v3.2 - Azure Foundry - It works partially, tools and todos not - similar tool execution/raw output issues with DeepSeek
• #234: Tool Calling Issues with Open Source Models in OpenCode - general tool calling failures and command execution problems

These issues share similarities with the model name and raw output problems you're experiencing. Feel free to ignore if none of these address your specific case.

updated models list, opencode models --refresh to apply

@rekram1-node thanks that solved the first problem, but the issue with tool execution going into chat is still there, is this an Abacus problem, or a opencode one?

[rekram1-node]

Okay I didn't setup the abacus provider im just trying to help yall out w/ it. My guess is that it doesnt have interleaved reasoning field set correctly in the models.dev models api.
