[FEATURE] Add Quartaly as a recognized provider in opencode models list

[clawdiobotelho]

Currently Quartaly API models are not showing in the opencode models list. Quartaly provides a OpenAI-compatible and Anthropic-compatible API at https://api.quatarly.cloud with various models including claude-opus-4-6-thinking, claude-sonnet-4-6-thinking, gpt-5.4, gemini-3.1-pro, etc.

Root Cause

The ProviderID schema is hardcoded in the opencode binary and only includes a fixed set of providers:

openrouter, anthropic, openai, google, google-vertex, github-copilot, amazon-bedrock, azure, mistral, gitlab

Any custom provider (like quartaly) that isn't in this list won't be shown in opencode models, even when credentials are configured in auth.json.

Current workaround

Custom providers can be configured in ~/.openclaw/agents/main/agent/models.json for the openclaw agent, but this doesn't affect the opencode model selector /models.

Request

Add quartaly to the list of recognized ProviderIDs so that:

1. The quartaly API credentials stored in auth.json are picked up
2. Quartaly models appear in opencode models output
3. Users can select Quartaly models via the model selector UI

API Details

• Quartaly OpenAI-compatible: https://api.quatarly.cloud/v1 (models: claude-sonnet-4-6, claude-opus-4-6-thinking, gpt-5.2-codex, gemini-3.1-pro-high, etc.)
• Quartaly Anthropic-compatible: https://api.quatarly.cloud/ (models: claude-haiku-4-5-20251001, claude-opus-4-6-thinking, etc.)
• API Key: stored as QUATARLY_API_KEY env var

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

• [Feature Request]: Allow dynamic model passthrough for custom OpenAI-compatible providers without explicit declaration #18219: Allow dynamic model passthrough for custom OpenAI-compatible providers without explicit declaration (covers the general problem of custom/unlisted providers not showing up in model lists)
• Auto-discover models from OpenAI-compatible provider endpoints #6231: Auto-discover models from OpenAI-compatible provider endpoints (similar request to surface custom provider models)
• [FEATURE]: Include custom providers in /provider and /connect command #5250: Include custom providers in /provider and /connect command

Additionally, note that the workaround mentioned references ~/.openclaw/ which doesn't appear to be a standard opencode path — you may want to verify this detail.

If your issue is specifically about adding Quartaly as a first-class built-in provider (rather than fixing support for arbitrary custom providers), it is also similar in nature to other provider-addition requests like #7594, #14106, and #16604.

quatarly.cloud is a scam. Operator: Quatarly (api.quatarly.cloud / api.neokens.com)
Mechanism: Routes all "GPT" model names (gpt-5.5, gpt-5.4, gpt-5.3-codex, gpt-5.2, gpt-5.1) to a single backend model that self-identifies as GPT-4-turbo (gpt-4-turbo-2024-04-09). Accidentally exposes Chinese model zai-org/GLM-5.1 (Zhipu AI / Z.ai). Injects a ~704-token system prompt enforcing English-only output to mask the model's Chinese tendencies.
