[Bug]: Some OpenCode models (like GLM 5.2) fail with `HTTP 404 — Not Found | opencode`

[sylvesterroos]

Bug Description

Some models like GLM 5.2 and Kimi K2.7 fail with the following message in the chat: API call failed after 3 retries: HTTP 404 — Not Found | opencode

This fails with any message, and at the start of the session

Steps to Reproduce

1. Have an OpenCode Go subscription
2. Switch to GLM 5.2 as the model
3. Send any message

Expected Behavior

GLM 5.2, Kimi K2.7, and any other failing models should work

Actual Behavior

The error I get back is API call failed after 3 retries: HTTP 404 — Not Found | opencode

Affected Component

CLI (interactive chat)

Messaging Platform (if gateway-related)

N/A (CLI only)

Duplicate of #54147 — same root cause: hermes chat -m <model> on OpenCode Go inherits a stale api_mode (anthropic_messages) from the config default, so non-MiniMax models (GLM 5.2, Kimi K2.7) route to the wrong endpoint and 404 at session start. Fix is tracked in the open PR #54148. The Desktop model-switch surface is #57259 and the gateway /model variant is #56158 (both related). Workaround: pin model.default in config.yaml per #54147.

Thanks for the report. This is already fixed on current main; this is an automated hermes-sweeper review.

• Commit 6eb39c2bbea97941e333e17bec64a8c20cb068ec (fix(opencode-go): heal stripped /v1 base_url so non-minimax models stop 404ing, fix(opencode-go): heal stripped /v1 base_url so non-minimax models stop 404ing #57585) re-derives OpenCode Go routing from the target model and restores /v1 for OpenAI-compatible requests.
• hermes_cli/models.py:3531 now normalizes official OpenCode Go URLs symmetrically, specifically repairing the prior GLM/Kimi chat-completions 404 path.
• Regression coverage in tests/hermes_cli/test_runtime_provider_resolution.py:1754 verifies a persisted stripped URL resolves to https://opencode.ai/zen/go/v1; tests/hermes_cli/test_model_validation.py:449 covers Kimi K2.7 and GLM 5.2 routing.
• The fix shipped in v2026.7.7 (Hermes Agent v0.18.1).

The related #54147 discussion correctly identified the stale routing family. Independent upstream OpenCode service errors may still occur, but the Hermes-side 404 route is addressed.
