Qwen3.6-35B-A3B hits instruction-following wall

Qwen3.6-35B-A3B, a sparse Mixture-of-Experts (MoE) model released in mid-April 2026, is facing community backlash for failing to adhere to system instructions and context files. Despite high SWE-bench scores, developers report significant regression in agentic obedience and tool-calling reliability compared to older models.

// ANALYSIS

The transition to sparse MoE appears to have traded reliable instruction adherence for benchmark performance. Reasoning loops and "thinking" mode bloat frequently lead the model to ignore constraints, while a high tool-call error rate and technical instability with FP8 KV cache make it a risky choice for production agents compared to Qwen 3.5.

Cline challenges GitHub Copilot team pricing

The open-source autonomous coding assistant Cline shared a cost comparison highlighting the pricing tiers of GitHub Copilot. While a 10-person team pays $2,280 annually and a 50-person team pays $11,400 for Copilot Business to get autocomplete functionality, Cline offers a fully autonomous, model-agnostic alternative where developers bring their own API keys, potentially saving teams significant licensing fees while unlocking agentic capabilities.

OpenRouter adds real-time cache hit rates to pricing

OpenRouter has added real-time cache hit rates and historical traffic metrics to its pricing tab, allowing developers to see actual provider performance data for models like Claude Opus 4.8. By visualizing these caching metrics directly, users can better understand the variance in pricing and choose model providers based on actual, effective costs rather than nominal list rates.
