259c7ec27a fix(ollama): preserve chat history with native context (#1805 )

* fix(ollama): preserve chat history with native context

Route Ollama chat requests through the native /api/chat endpoint so OpenClaude can send request-level options.num_ctx instead of relying on Ollama's OpenAI-compatible shim.

Default the Ollama request context to 32768 tokens, support OPENCLAUDE_OLLAMA_NUM_CTX and OLLAMA_CONTEXT_LENGTH overrides, and map max tokens/temperature/top_p into native Ollama options.

Adapt native Ollama streaming and non-streaming responses back into the existing OpenAI-shaped conversion pipeline, including usage, text, structured tool calls, and tool_use stop reasons.

Normalize native Ollama request messages for images and historical tool calls, avoiding OpenAI-only image_url/id/type payload fields in /api/chat requests.

Add Ollama context diagnostics, loopback-only ollama ps status checks, regression coverage, and documentation for verifying active context length.

* fix(ollama): address native routing review feedback

* fix(ollama): restrict loopback host matching

* fix(ollama): exclude wildcard bind address

* fix(ollama): keep https localhost proxies on chat completions

OpenClaude Quick Start for macOS and Linux

This guide uses a standard shell such as Terminal, iTerm, bash, or zsh.

1. Install Node.js

Install Node.js 22 LTS or newer from:

https://nodejs.org/

Then check it:

node --version
npm --version

2. Install OpenClaude

npm install -g @gitlawb/openclaude@latest

On Arch Linux, you can alternatively install OpenClaude via the community-maintained AUR package:

paru -S openclaude

3. Pick One Provider

Option A: OpenAI

Replace sk-your-key-here with your real key.

export CLAUDE_CODE_USE_OPENAI=1
export OPENAI_API_KEY=sk-your-key-here
export OPENAI_MODEL=gpt-4o

openclaude

Option B: DeepSeek

export CLAUDE_CODE_USE_OPENAI=1
export OPENAI_API_KEY=sk-your-key-here
export OPENAI_BASE_URL=https://api.deepseek.com/v1
export OPENAI_MODEL=deepseek-v4-flash

openclaude

Use deepseek-v4-pro when you want the stronger model. deepseek-chat and deepseek-reasoner still work as DeepSeek's legacy API aliases.

Option C: Ollama

Install Ollama first from:

https://ollama.com/download

Then run:

ollama pull llama3.1:8b

export CLAUDE_CODE_USE_OPENAI=1
export OPENAI_BASE_URL=http://localhost:11434/v1
export OPENAI_MODEL=llama3.1:8b

openclaude

No API key is needed for Ollama local models.

OpenClaude asks Ollama for a 32768-token context window on each chat request. If you need a different size, set OPENCLAUDE_OLLAMA_NUM_CTX before launching OpenClaude, or start Ollama with a global context setting:

# Stop any existing Ollama app/server first, then run:
OLLAMA_CONTEXT_LENGTH=32768 ollama serve

After a chat request, run ollama ps in another terminal and check the CONTEXT column. It should show the requested size. If it still shows a small value such as 4K, restart the Ollama app/server and try again.

Option D: LM Studio

Install LM Studio first from:

https://lmstudio.ai/

Then in LM Studio:

Download a model (e.g., Llama 3.1 8B, Mistral 7B)
Go to the "Developer" tab
Select your model and enable the server via the toggle

Then run:

export CLAUDE_CODE_USE_OPENAI=1
export OPENAI_BASE_URL=http://localhost:1234/v1
export OPENAI_MODEL=your-model-name
# export OPENAI_API_KEY=lmstudio  # optional: some users need a dummy key

openclaude

Replace your-model-name with the model name shown in LM Studio.

No API key is needed for LM Studio local models (but uncomment the OPENAI_API_KEY line if you hit auth errors).

Option E: Using a .env file (Optional)

If you prefer to keep your keys in a .env file instead of exporting them individually, note that OpenClaude does not load .env files automatically. You must explicitly pass it:

openclaude --provider-env-file .env

Keep .env out of git because it contains secrets. The explicit loader accepts provider/setup variables. Export runtime/debug variables from your shell or launcher instead.

4. If `openclaude` Is Not Found

Close the terminal, open a new one, and try again:

openclaude

5. If Your Provider Fails

Check the basics:

For OpenAI or DeepSeek

make sure the key is real
make sure you copied it fully

For Ollama

make sure Ollama is installed
make sure Ollama is running
make sure the model was pulled successfully
if same-session chat history appears missing, verify the active CONTEXT value with ollama ps; OpenClaude requests 32K by default

For LM Studio

make sure LM Studio is installed
make sure LM Studio is running
make sure the server is enabled (toggle on in the "Developer" tab)
make sure a model is loaded in LM Studio
make sure the model name matches what you set in OPENAI_MODEL

6. Updating OpenClaude

Via npm:

npm install -g @gitlawb/openclaude@latest

Via AUR:

paru

(Or use your preferred AUR helper like yay -Syu)

7. Uninstalling OpenClaude
