What changed

HAI is a Japan-based OpenAI-compatible LLM Inference API with JPY billing.

This plugin adds a predefined-model provider that points at https://hai-api.hcloud.ltd/v1 and ships catalog entries for:

• kimi-k2.6 (default validation model)
• kimi-k3
• deepseek-v4-flash
• qwen3.6-35b-a3b
• qwen3.6-35b-a3b-uncensored
• gemma-4-31b-it

Website: https://hai.hcloud.ltd
Docs: https://hai.hcloud.ltd/docs
Console / API keys: https://hai.hcloud.ltd/console/

Risk level

• Low risk
• Medium risk
• High risk

The plugin only calls the fixed HAI HTTPS API endpoint and does not execute user-controlled code, commands, SQL, file operations, browser automation, or arbitrary network requests.

Required checks

• I have read and followed the Marketplace submission requirements.
• I have read and comply with the Plugin Developer Agreement.
• I tested this plugin package contents and documented limitations below.
• The package contains only files needed at runtime.
• The package does not contain secrets, local credentials, .env files, .git directories, virtual environments, caches, logs, or IDE files.
• The package does not contain executables or bundled binaries.
• The plugin README includes setup steps, usage instructions, required APIs or credentials, connection requirements, and the source repository link.
• The plugin includes PRIVACY.md.
• All user-facing text is primarily in English, with Japanese README under readme/README_ja_JP.md.

Security and privacy notes

None beyond transmitting prompt content and the API key to the configured HAI endpoint (https://hai-api.hcloud.ltd). See PRIVACY.md inside the package.

Local validation

• Packaged as rluisr/hai/hai-0.0.1.difypkg (zip of plugin root with manifest, provider, models, README, PRIVACY.md, assets).
• Live credential validation against production HAI requires a hai_... key from the console; not included in this PR.

Reviewer notes

• Author is rluisr (not reserved).
• Implementation uses OAICompatLargeLanguageModel with default base URL https://hai-api.hcloud.ltd/v1.

Hi @rluisr — thanks for the new provider contribution! The package is very close. The remaining blocker is that dify_plugin is not installed by the package; please include dify_plugin>=0.9.0 in requirements.txt and repack the .difypkg. Once updated, we will be happy to take another look. 🙏

[rluisr]

Thanks for the review @crazywoola — updated.

• Added requirements.txt with dify_plugin>=0.9.0
• Bumped the same pin in pyproject.toml
• Repacked rluisr/hai/hai-0.0.1.difypkg

Ready for another look.

Hi @rluisr — here is the current CI summary for commit 27858db.

❌ Blocking errors

• manifest.yaml is missing the required repo and contact fields.

⚠️ Warnings / review items

• Add the recommended meta.minimum_dify_version field.
• dify_plugin>=0.9.0 has a lower-bound-only constraint in both requirements.txt and pyproject.toml.
• Python-safety review: models/llm/llm.py:21 may return credential-like values through super()._invoke(... credentials ...).
• Workflow infrastructure warning (not caused by this PR): checkout/setup-python still target deprecated Node.js 20 and are being forced onto Node.js 24.

The current log no longer reports the earlier missing-dify_plugin dependency problem; the manifest fields above are the remaining blockers in this run.
