From fa9d3d8a6b45db195c3fd442a0b70559e360fe89 Mon Sep 17 00:00:00 2001 From: Claude Code Date: Wed, 15 Oct 2025 16:07:17 +0200 Subject: [PATCH] Add Ollama support for local LLM models (Phase 2 complete) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Major Changes: - Added Ollama as alternative LLM provider to OpenAI - Implemented flexible provider switching via environment variables - Support for multiple embedding models (OpenAI and Ollama) - Created comprehensive Ollama setup guide Configuration Changes (config.py): - Added LLM_PROVIDER and EMBEDDER_PROVIDER settings - Added Ollama configuration: base URL, LLM model, embedding model - Modified get_mem0_config() to dynamically switch providers - OpenAI API key now optional when using Ollama - Added validation to ensure required keys based on provider Supported Configurations: 1. Full OpenAI (default): - LLM_PROVIDER=openai - EMBEDDER_PROVIDER=openai 2. Full Ollama (local): - LLM_PROVIDER=ollama - EMBEDDER_PROVIDER=ollama 3. Hybrid configurations: - Ollama LLM + OpenAI embeddings - OpenAI LLM + Ollama embeddings Ollama Models Supported: - LLM: llama3.1:8b, llama3.1:70b, mistral:7b, codellama:7b, phi3:3.8b - Embeddings: nomic-embed-text, mxbai-embed-large, all-minilm Documentation: - Created docs/setup/ollama.mdx - Complete Ollama setup guide - Installation methods (host and Docker) - Model selection and comparison - Docker Compose configuration - Performance tuning and GPU acceleration - Migration guide from OpenAI - Troubleshooting section - Updated README.md with Ollama features - Updated .env.example with provider selection - Marked Phase 2 as complete in roadmap Environment Variables: - LLM_PROVIDER: Select LLM provider (openai/ollama) - EMBEDDER_PROVIDER: Select embedding provider (openai/ollama) - OLLAMA_BASE_URL: Ollama API endpoint (default: http://localhost:11434) - OLLAMA_LLM_MODEL: Ollama model for text generation - OLLAMA_EMBEDDING_MODEL: Ollama model for embeddings - MEM0_EMBEDDING_DIMS: Must match embedding model dimensions Breaking Changes: - None - defaults to OpenAI for backward compatibility Migration Notes: - When switching from OpenAI to Ollama embeddings, existing embeddings must be cleared due to dimension changes (1536 → 768 for nomic-embed-text) - Update MEM0_EMBEDDING_DIMS to match chosen embedding model Benefits: ✅ Cost savings - no API costs with local models ✅ Privacy - all data stays local ✅ Offline capability - works without internet ✅ Model variety - access to many open-source models ✅ Flexibility - easy switching between providers Version: 1.1.0 Status: Phase 2 Complete - Production Ready with Ollama Support 🤖 Generated with Claude Code Co-Authored-By: Claude --- .env.example | 22 +- README.md | 85 ++++++-- config.py | 81 ++++++-- docs/setup/ollama.mdx | 474 ++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 621 insertions(+), 41 deletions(-) create mode 100644 docs/setup/ollama.mdx diff --git a/.env.example b/.env.example index ceff2e9..03ac8f0 100644 --- a/.env.example +++ b/.env.example @@ -1,19 +1,31 @@ -# OpenAI Configuration -OPENAI_API_KEY=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 +# LLM Provider Selection +# Options: "openai" or "ollama" +LLM_PROVIDER=openai +EMBEDDER_PROVIDER=openai +# OpenAI Configuration +# Required when LLM_PROVIDER=openai or EMBEDDER_PROVIDER=openai +OPENAI_API_KEY=sk-your-openai-api-key-here + +# Ollama Configuration +# Required when LLM_PROVIDER=ollama or EMBEDDER_PROVIDER=ollama +# Ollama must be running and models must be pulled +OLLAMA_BASE_URL=http://localhost:11434 +OLLAMA_LLM_MODEL=llama3.1:8b +OLLAMA_EMBEDDING_MODEL=nomic-embed-text # Supabase Configuration -SUPABASE_CONNECTION_STRING=postgresql://postgres:CzkaYmRvc26Y@172.21.0.8:5432/postgres +SUPABASE_CONNECTION_STRING=postgresql://user:password@host:5432/database # Neo4j Configuration NEO4J_URI=neo4j://neo4j:7687 NEO4J_USER=neo4j -NEO4J_PASSWORD=rH7v8bDmtqXP +NEO4J_PASSWORD=your-neo4j-password # API Configuration API_HOST=0.0.0.0 API_PORT=8080 -API_KEY=mem0_01KfV2ydPmwCIDftQOfx8eXgQikkhaFHpvIJrliW +API_KEY=your-secure-api-key-here # MCP Server Configuration MCP_HOST=0.0.0.0 diff --git a/README.md b/README.md index 11a7f0b..5556185 100644 --- a/README.md +++ b/README.md @@ -11,7 +11,10 @@ Comprehensive memory system based on mem0.ai featuring MCP server integration, R -
