Benchmarking OpenCode's Free Tier: 450-766 Requests/Day, Not the Rumored 200

If you build with, or are thinking of using, OpenCode.ai (oc, for short) for development or agent work, you’ve probably felt this anxiety: worried the models won’t match the official ones, worried the free tier will hit its limit every day, or puzzled over how the Go subscription quota is even calculated, especially with claims floating around about burning through half a month’s quota in 5 minutes. Once DeepSeek V4 Flash (ds4f, for short) stabilized, the token constraint issues became much easier to manage. I analyzed over 3,000 API call logs from my local machine across three months of active usage and cross-checked them against the numbers online. Here’s the truth behind these five misconceptions. Once you get these straight, your workflow runs steadier, and you stop worrying about burning through your token quota. ...

DeepSeek's Price Increase Goes Beyond GPU Costs

TL;DR: On August 6, 2026, DeepSeek announced that it plans to raise API prices. No single cause: cost pass-through, user filtering, expectation management, free marketing, a shift to value-based pricing, and open-source ecosystem pressure all point at the same move. Rising compute costs are real, but they don’t explain the timing or the form of the announcement. The market is largely moving from winning share with low prices toward value-based pricing, and seven falsifiable signals before the official plan will confirm or overturn this post’s inferences. ...

OpenCode Cold Start: DeepSeek V4 Flash Free in 5 Minutes

This is a bonus article for the “AI Path L1→L2 Upgrade Guide.” If you have not installed OpenCode yet, this guide gets you from zero to running. In Day 8 you learned about autonomous execution AI. The next step is actually installing and configuring OpenCode. OpenCode is an open-source AI coding assistant. It is free, supports multiple models, and has a skill system. Paired with OpenCode Zen, you can use tested models without setting up third-party API keys, including the free DeepSeek V4 Flash. ...

Day 1 Exercise: Run Your First API Code

This is the Day 1 companion exercise for the AI Path L1→L2 Upgrade Guide. Read Part 1 first, then come back here to practice. Today we do exactly one thing: run the hello_api.py from Part 1 and see AI reply in your terminal. Prerequisites Complete these steps from Part 1 (skip if already done): Register a DeepSeek developer account (Part 1, “Register for API Accounts”) Get your API Key and save it to a .env file (Part 1, “API Key Safety”) Install uv and Python 3.12 (Part 1, “Install Python”) Create a virtual environment and install dependencies (Part 1, “Create a Virtual Environment”) Confirm your project directory looks like this: ...

Pick Your AI by the Job, Not the Ranking

Tried ChatGPT, Claude, Gemini, DeepSeek… and still can’t decide which one to stick with? Here’s the thing: that’s the wrong question. There is no universally best AI — only the one that fits what you’re doing right now. What’s your scenario? “I want a general-purpose assistant for everything” → ChatGPT. As of May 2026 the default is GPT-5.5 — well-rounded, with the richest plugin ecosystem. If you pick just one, this is a solid choice. ...
