I’m currently paying $80/month to subscribe to two GitHub Copilot Pro+ accounts. That number seems steep at first, but after three months of use, I believe it’s the best ROI among all my AI subscriptions. This article breaks down the math so you can judge for yourself whether it’s worth it. What is Copilot Pro+? GitHub Copilot has three tiers: Tier Monthly cost Key difference Copilot Free Free Basic completions, 2000 completions/month Copilot Pro $10 Unlimited completions, GPT-4o model Copilot Pro+ $19 Unlimited completions + advanced model quota The key differences in Pro+: ...

💡 Mainland China Notice: Binance’s official site is not directly accessible from mainland China — you’ll need to provide your own network tools to access it. Fiat deposits don’t support bank cards; deposits happen mainly through C2C channels (USDT ↔ CNY). Profitability in algorithmic trading is heavily determined by trading fees. A strategy executing 100 trades per month at 0.1% fees incurs 20% in costs on both sides. Reducing fees from 0.1% to 0.05% yields significant annual savings. ...

Anthropic’s current flagship models are Opus 4.6 (most powerful), Sonnet 4.6 (balanced), and Haiku 4.5 (fastest and cheapest). Many people use Claude for everything with Opus, resulting in API bills 3–5× higher. This article explains from a practical usage perspective: when to use Opus, when to use Sonnet, and when Haiku is worth considering. Pricing Comparison (April 2026) Model Input Price Output Price Relative Cost claude-haiku-4-5 $0.80/M tokens $4/M tokens 1× claude-sonnet-4-6 $3/M tokens $15/M tokens ~4× claude-opus-4-6 $15/M tokens $75/M tokens ~19× Opus costs nearly 20× more than Haiku. For the same task, using Opus when Sonnet can handle it is pure waste. ...

Running OpenClaw with default config will hit two problems after a while: quota burns too fast and long sessions crash from timeouts. This post logs 8 parameters I actually tuned, and the reasoning behind each. Architecture First Here’s my setup: GitHub Copilot Pro+: $19/month, 1500 premium requests/month quota Claude Opus 4.6: accessed via Copilot’s model routing, model ID github-copilot/claude-opus-4.6 OpenClaw: handles Telegram interactions, Skill calls, scheduled tasks Quota math: each AI assistant reply = 1 premium request (including replies after tool calls). 1500 sounds like plenty, but without optimization it dries up fast. ...

Claude API costs can easily spiral out of control—stronger models cost more per call, and longer context costs more. This post shares my approach to cost control. Claude Model Pricing Comparison (2026) Model Input $/MTok Output $/MTok Use case claude-opus-4-6 $15 $75 Complex reasoning, code generation claude-sonnet-4-6 $3 $15 General tasks, writing claude-haiku-4-5 $0.8 $4 Simple classification, summarization MTok = million tokens. 1 token ≈ 0.75 English words ≈ 0.5 Chinese characters. ...
