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

• Ollama custom provider error : agent configured model is not valid #8950: Same error message ("agent configured model is not valid") with a custom provider model
• Model IDs with slashes are broken #15668: Model IDs with slashes (like chutes/XiaomiMiMo/MiMo-V2-Flash-TEE) are broken — the multi-segment path may be the root cause here
• Chutes AI "Qwen3.5-397B-A17B-TEE" model not showing in Zen or Web UI #14061: Chutes AI model not recognized in OpenCode (same provider)

#8950 => not relevant, used double-quotes, and also no colons in the model name
#15668 => not relevant, does not start with a slash, follows chutes-based format
#14061 => semi-relevant, we do not need the UX to display the options, as this is purely from config.json so @mugnimaestra could answer this issue. the {model-provider}/{model-source}/{model-name} format is obeyed, and that the name exactly matches ChutesAI's index.
For some reason Kimi-K2.5, DeepSeek-v3.2, and MiniMax-M2.5 matches well, but NOT MiMo-V2-Flash as the odd one out.
chutes/XiaomiMiMo/MiMo-V2-Flash is the assumed model name but it does NOT match the official ChutesAI format, and that opencode models --refresh shows this key issue. See https://chutes.ai/app/chute/18aab253-1f97-5279-bef7-499f1f837653
