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:

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

🌟 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
