+### Working with Knowledge Collections (small context window survival guide)
+
+With small local models (4B-9B, 4K-8K context), you'll hit the context window limit fast — often after 10-20 exchanges. Here's how to work effectively despite that.
+
+#### How Knowledge Collections actually work
+
+When you type `#` in chat and select a collection, Open WebUI does **RAG retrieval** — it finds the most relevant chunks from the collection, not the whole thing. This is efficient and doesn't blow up your context window.
+
+- Default chunk size: ~500 tokens
+- Typically 3-5 relevant chunks are retrieved per query (~1500-2500 tokens)
+- The chunks are injected as context alongside your message
+
+#### Creating Knowledge Collections from chat conversations
+
+There is **no built-in "export chat to knowledge" button** — this is a requested but unimplemented feature. Here's the practical workflow:
+
+**The handoff method (like the ChatGPT dark ages, but structured):**
+
+1. When you're ~60-70% through your context window (you'll feel the model getting fuzzy), ask:
+   ```
+   Summarize everything we've discussed and decided so far. Include:
+   - Key decisions made
+   - Current state of the work
+   - What still needs to be done
+   - Any important details or constraints
+   Format as a structured document I can use to continue this conversation.
+   ```
+2. **Copy the summary output**
+3. Go to **Workspace → Knowledge → Create Collection** (e.g. "GPU Build - Session 1")
+4. Click **Add Content** → paste the summary as a text file (`.txt` or `.md`)
+5. Start a **new chat**, type `#` and select your collection, then continue where you left off
+
+**Ongoing project workflow:**
+
+```
+Chat 1: Research phase
+  → Ask for summary at end
+  → Save summary to "Project X" knowledge collection
+
+Chat 2: Type # → select "Project X" → continue
+  → Model gets relevant context via RAG
+  → Ask for updated summary at end
+  → Add updated summary to collection (replace or append)
+
+Chat 3: Type # → select "Project X" → continue
+  → Repeat...
+```
+
+Each chat starts fresh with full context window available, but can pull in relevant history from previous sessions via RAG.
+
+#### Useful community functions for context management
+
+Install these manually (Workspace → Functions → Create, paste the code):
+
+| Function | What it does |
+|----------|-------------|
+| **Checkpoint Summarization Filter** | Auto-summarizes conversation history when context gets long |
+| **Chat Context Clipper** | Keeps only the last N messages, preserves system prompt and first message |
+| **Context Length Filter** | Hard limits on turns (default 25) and tokens (default 10,000) |
+
+The **Checkpoint Summarization Filter** is the closest to automatic handoff — it summarizes older messages so the model can keep going without losing track.
+
+#### How Open WebUI handles context overflow
+
+By default, Open WebUI **truncates** old messages (drops them silently) — it does NOT auto-summarize. The model just loses access to earlier conversation. This is why you suddenly feel like the model "forgot" what you were talking about.
+
+You can control this with:
+- **Context Length Filter** function: set max turns and token limits explicitly
+- **Chat Context Clipper**: keeps latest N messages, always preserves system prompt + first message pair
+- Or do manual handoffs before you hit the limit
+
+#### RAG tuning for better knowledge retrieval
+
+If your knowledge collections aren't returning good results, tune these in **Admin → Settings → Documents**:
+
+| Setting | Default | Recommendation |
+|---------|---------|---------------|
+| Chunk Size | 500 | 300 for factual docs, 800 for narrative/code |
+| Chunk Overlap | 100 | 50-100 (higher = better continuity, more tokens) |
+| Top K | 4 | 3-5 (more = more context consumed) |
+| Relevance Threshold | 0.0 | 0.3-0.5 (filters out low-quality matches) |
+
+**Important:** Chunk size cannot exceed your embedding model's token limit. `nomic-embed-text` supports up to 8192 tokens, so you have plenty of headroom.
+
+#### The honest comparison: Local AI vs Claude Code
+
+| | **Local AI (Open WebUI + Ollama)** | **Claude Code** |
+|---|---|---|
+| **Context window** | 4K-32K (model dependent) | 200K |
+| **Cross-session memory** | Manual handoffs or Auto Memory | Automatic (CLAUDE.md, project memory) |
+| **Project scoping** | Knowledge collections (manual) | Built-in (each project has its own context) |
+| **Code awareness** | None — you paste code in | Reads your entire codebase |
+| **Continuation** | New chat + `#collection` handoff | "Let's finish X" just works |
+| **Cost** | Free (your electricity) | API usage fees |
+| **Privacy** | 100% local | Cloud-based |
+| **Offline** | Works without internet | Requires internet |
+
+Local AI requires more manual workflow management. The tradeoff is privacy, cost, and offline capability. For code-heavy work, Claude Code is dramatically better. For private research, document Q&A, and learning — local models with knowledge collections work well once you get the handoff workflow down.

 ### Channels (beta feature)
 
 Channels are persistent chat rooms (like Slack/Discord channels) with multi-model support. They do NOT scope memories differently — memories are still global per user. Channels are useful for team collaboration, not memory isolation.
