codex-deepseek-vision

Codex vision bridge for DeepSeek V4 Flash and other text-only models. Package/CLI: agent-vision. DeepSeek V4 Flash now speaks the Responses protocol and runs inside Codex/ChatGPT, but the model itself is text-only and cannot see images. agent-vision is a free local vision proxy: pasted images and view_image calls are converted into text through an OpenAI-compatible vision API (free GLM-4V-Flash by default) before DeepSeek reasons. No Ollama, no GPU, no model swap.

Why

Text-only agents cannot see pasted screenshots, local images, charts, or error dialogs. Replacing the model usually means paying more or changing your whole workflow. agent-vision sits between the agent and its model provider and does the conversion automatically:

• Paste an image in your agent, and the local proxy rewrites it into text before the request reaches the text-only model.
• Ask the agent to inspect a local image, an image URL, or the latest image you pasted (see --latest), and it returns a factual description.
• Keep your existing model, key, and workflow. Everything is local, reversible, and free by default.

Architecture

flowchart LR
  U[User pastes an image] --> A[Any AI agent]
  A -->|request with image| P[agent-vision proxy :19100]
  P --> V[OpenAI-compatible vision API]
  V -->|text description| P
  P -->|text-only request| M[DeepSeek / text-only model]

see mode skips the proxy: the image path is sent directly to the vision API and the returned text is used by the agent.

Supported Agents

Supported Vision Providers

agent-vision accepts any OpenAI-compatible vision API. Built-in presets cover the most common ones; custom endpoints work too.

Click a provider name to open its official sign-up/console page and create an API key.

Install

One-line deploy (recommended)

Paste this into your AI agent:

Deploy agent-vision from https://github.com/SIMON-WORLD/codex-deepseek-vision per AGENT_INSTALL.md. Use the free Zhipu provider. Vision API key: <KEY>. Tell me when I need to restart Codex.

One-line install (recommended)

Install Python 3.9+, then run:

pip install codex-deepseek-vision
agent-vision setup

If PyPI is unreachable, install from the repository instead:

git clone https://github.com/SIMON-WORLD/codex-deepseek-vision.git
cd codex-deepseek-vision
pip install .
agent-vision setup

The wizard detects your agent, lets you pick Free / Quality / Custom vision, writes the config with a backup, starts the local runtime, verifies the connection, and prints the final health status. For Codex it only rewrites the active provider's base_url; model_provider, model, wire_api and API keys are left untouched.

You can also paste this into your agent and let it do the work:

Set up agent-vision for me. Read AGENT_INSTALL.md and follow it end to end. Use the free Zhipu provider unless I choose another one.

All user configuration lives in one directory: ~/.agent-vision/ on Linux/macOS, %USERPROFILE%\.agent-vision\ on Windows. Override it with AGENT_VISION_HOME if you prefer another location. The setup wizard creates and fills this directory automatically.

Runtime management

agent-vision start      # start the local vision proxy in the background
agent-vision status     # show installation, runtime, provider, agent and vision status
agent-vision restart    # restart the local proxy
agent-vision stop       # stop the local proxy

Rollback

agent-vision rollback codex
agent-vision rollback opencode

Every auto-patch creates a timestamped backup before modifying anything, and rollback restores it.

Configuration

agent-vision setup writes and manages .env inside the user config directory. For manual configuration, copy .env.example to ~/.agent-vision/.env (Windows: %USERPROFILE%\.agent-vision\.env) and fill in the vision API key. Zhipu keys use the {API Key ID}.{secret} format. Do not add quotes; the loader strips surrounding quotes and whitespace.

For a custom provider, ask your agent to add one to providers.json in the user config directory; no code changes are needed. Entries there override built-in presets with the same id.

CLI Reference

# Analyze images on demand (local file, image URL, or latest pasted image)
agent-vision see <image-or-url>... [-q "question"] [--task describe|ocr|ui|chart] [--latest] [--provider ID] [--no-cache]

# Run the local image-strip proxy in the foreground
agent-vision proxy --listen 127.0.0.1:19100 --upstream <origin>

# Guided setup
agent-vision setup [--agent codex|opencode|claude|cursor] [--dry-run]

# Health status
agent-vision status [--test]

# Runtime lifecycle
agent-vision start | restart | stop

# Configuration check
agent-vision doctor

# List vision provider presets

Self-test in 3 minutes

Anyone with Python 3.9+ can verify the bridge on a fresh machine:

git clone https://github.com/SIMON-WORLD/codex-deepseek-vision.git
cd codex-deepseek-vision
pip install .
agent-vision setup
agent-vision status

Then paste an image in Codex or ask the agent to call view_image on a local image. For a zero-setup fresh machine, open this repository in GitHub Codespaces: the devcontainer pre-installs the package, and all commands above run the same way.

Testing

python -m unittest discover -s tests -v

FAQ

• Do I need a GPU or Ollama? No. Vision is handled by a remote OpenAI-compatible API; the default Zhipu glm-4v-flash is free.
• Is my agent key exposed? No. The proxy passes the original Authorization header through, so your main model key stays in the agent's existing config.
• Why does Codex still refuse pasted images ("model does not support image input")? Codex decides whether the UI accepts pasted images from its model catalog. When you load models from a local catalog (e.g. cc-switch's model_catalog_json), setup now also declares image input for the active text-only model (with a timestamped backup; rollback codex restores it). If you switch models with cc-switch afterwards, that file may be regenerated — rerun agent-vision setup to re-apply.
• Can the agent call Codex's built-in view_image? Yes. view_image sends the local image in a later request, and the same proxy converts it to text before the text-only model sees it. If your client refuses pasted images entirely, run agent-vision see --latest to recover the last image pasted into Codex from session files and analyze it directly.
• Can I use a paid provider? Yes. Choose Quality or Custom in setup, or edit .env / providers.json.
• What happens if the vision API fails? Proxy mode fails open and forwards the original request unchanged, so normal chat is not blocked.
• Are images private? Images are sent only to the provider you configure (Zhipu by default). Review the provider policy before sending sensitive screenshots. see --latest extracts only the image bytes from Codex session files and never reads or sends conversation text. .env is gitignored; never commit or share it.
