# v1.1.14-beta - READY FOR RELEASE 🎉

**Date:** 2025-10-05
**Status:** ✅ **BETA READY**
**Major Achievement:** OpenRouter proxy fixed and working!

---

## 🎯 What Was Fixed

### Critical Bug: TypeError on anthropicReq.system

**Problem:**
```typescript
TypeError: anthropicReq.system?.substring is not a function
```

**Root Cause:**
- Anthropic API allows `system` field to be **string** OR **array of content blocks**
- Claude Agent SDK sends it as **array** (for prompt caching features)
- Proxy code assumed **string only** → called `.substring()` on array → crash
- **Result: 100% failure rate for all OpenRouter requests**

**Solution:**
- Updated TypeScript interface to allow both types
- Added type guards and safe extraction logic
- Extract text from content block arrays
- Comprehensive verbose logging for debugging

**Files Changed:**
- `src/proxy/anthropic-to-openrouter.ts` - Type safety + array handling + logging

---

### MCP Tools Validation

✅ **All 15 MCP tools forwarding successfully:**
- Task, Bash, Glob, Grep, ExitPlanMode
- Read, Edit, Write, NotebookEdit
- WebFetch, TodoWrite, WebSearch
- BashOutput, KillShell, SlashCommand

**Evidence:**
```
[INFO] Tool detection: {"hasMcpTools":true,"toolCount":15}
[INFO] Forwarding MCP tools to OpenRouter {"toolCount":15}
[INFO] RAW OPENAI RESPONSE {"finishReason":"tool_calls","toolCallNames":["Write"]}
```

### File Operations Tested

✅ **Write Tool:** File created successfully
```bash
$ cat /tmp/test3.txt
Hello
```

✅ **Read Tool:** File read successfully
✅ **Bash Tool:** Commands executed

**Proxy successfully converts:**
- Anthropic tool format → OpenAI function calling
- OpenAI tool_calls → Anthropic tool_use format
- Full round-trip working!

## 🌟 October 2025 Popular Models (Research)

Based on OpenRouter rankings, these are the most used models:

**Top 5 by Usage:**
1. **x-ai/grok-code-fast-1** - 865B tokens (47.5%) - #1 most popular!
2. **anthropic/claude-4.5-sonnet** - 170B tokens (9.3%)
3. **anthropic/claude-4-sonnet** - 167B tokens (9.2%)
4. **x-ai/grok-4-fast** - 108B tokens (6.0%)
5. **openai/gpt-4.1-mini** - 74.2B tokens (4.1%)

**Why Grok Is Dominating:**
- **Pricing:** $0.20/M input, $0.50/M output (15× cheaper than GPT-5)
- **Free tier:** `:free` endpoint available
- **Performance:** "Maximum intelligence per token"
- **Dual mode:** Reasoning + non-reasoning on same weights

**Free Models Available:**
- `deepseek/deepseek-r1:free`
- `deepseek/deepseek-chat-v3-0324:free`
- `x-ai/grok-4-fast` (via :free endpoint)
- Mistral, Google, Meta models

---

## 🚧 Known Issues

### Llama 3.3 70B Timeout
**Status:** Intermittent timeout after 20s

**Analysis:** Not related to system field bug (that's fixed). Possibly:
- Model-specific OpenRouter routing issue
- Network latency for large model
- Rate limiting

**Mitigation:** Use Llama 3.1 8B instead (works perfectly)

### xAI Grok 4 Timeout
**Status:** Consistent timeout after 60s

**Analysis:** Grok 4 (full reasoning model) too slow for practical use

**Mitigation:** Use Grok 4 Fast instead - tested and working perfectly!

### GLM 4.6 Output Quality
**Status:** Garbled output with encoding issues

**Output Example:** Mixed character encodings, non-English characters in English prompts

**Analysis:** Model may have language detection or encoding issues

**Recommendation:** Not recommended for production use

### DeepSeek Models
**Status:** Not fully tested (API key environment issue in test environment)

**Models to test:**
- `deepseek/deepseek-chat`
- `deepseek/deepseek-r1:free`
- `deepseek/deepseek-coder-v2`

**Recommendation:** Test in production environment with proper API keys
