OpenCode itself is an open-source coding agent with 160,000 GitHub stars, 900 contributors, and 7.5 million monthly active developers. It runs in your terminal, your IDE, or as a desktop app. It connects to 75+ AI providers.<\/p>\n<figure class=\"wp-block-image aligncenter size-large\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-hero-3.webp\" alt=\"free ai providers 2026 hero image\" width=\"1200\" height=\"675\" class=\"wp-image-1224\"\/><\/figure>\n<p class=\"wp-block-paragraph\">Go is not the agent.  This is exactly the kind of opencode go setup I would build for myself.Go is the model access subscription. You can use OpenCode without Go \u2014 bring your own API keys for Claude, GPT, Gemini, Ollama, or any of the 75+ supported providers. Go is the option for developers who want a curated set of coding models without managing multiple API accounts.<\/p>\n<p class=\"wp-block-paragraph\">OpenCode Zen is the companion pay-as-you-go tier.  This is where opencode go becomes essential.Zen gives you the same curated model list as Go but charges per token instead of a flat subscription. Zen is for developers who want predictable per-request pricing. Go is for developers who hit the API enough that $10\/month is cheaper than per-token charges.<\/p>\n<p class=\"wp-block-paragraph\">Both Zen and Go come with an OpenAI-compatible API.  For anyone comparing opencode go, the limit is the real spec.Change the base URL, use the same client library, call the same endpoints. The API key works with any agent, not just OpenCode \u2014 I use mine with my Python pipeline scripts.<\/p>\n<p class=\"wp-block-paragraph\">&#8212; If you are evaluating opencode go in 2026, the free tier is the only one that matters for prototyping.<\/p>\n<h2 class=\"wp-block-heading\" id=\"pricing-5-first-month-then-10-month\">Pricing: $5 First Month, Then $10\/Month<\/h2>\n<p class=\"wp-block-paragraph\">OpenCode Go costs $5 for the first month and $10\/month after that. There is no annual contract. You can cancel any time. The subscription auto-renews but you can top up credit if you exceed the included limits and need more before the renewal date.<\/p>\n<figure class=\"wp-block-image aligncenter size-large\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-models.webp\" alt=\"free ai providers 2026 - models illustration\" width=\"1024\" height=\"768\" class=\"wp-image-1225\" srcset=\"https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-models.webp 1024w, https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-models-300x225.webp 300w, https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-models-768x576.webp 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<p class=\"wp-block-paragraph\">The pricing is flat, not per-token.  Most reviews of opencode go skip the limits page. The limits page is the actual product.You get a usage budget defined in dollar value:<\/p>\n<li>$12 of usage per 5 hours<\/li>\n<li>$30 of usage per week<\/li>\n<li>$60 of usage per month<\/li>\n<p class=\"wp-block-paragraph\">The model you use determines how many requests that budget buys. DeepSeek V4 Flash, the cheapest model on Go, gives you approximately 31,650 requests per 5-hour window. GLM-5.1, the most expensive coding model on Go, gives you approximately 880 requests in the same window. The table below from the OpenCode Go docs shows the exact per-model request counts based on typical usage patterns.<\/p>\n<p class=\"wp-block-paragraph\">The budgets reset on a rolling basis.  This is where opencode go becomes essential.The 5-hour limit resets 5 hours after your first request in that window. The weekly limit resets every Monday. The monthly limit resets on your billing date.<\/p>\n<p class=\"wp-block-paragraph\">For my workload \u2014 a mix of structured JSON generation with DeepSeek V4 Flash and complex code generation with GLM-5.1 \u2014 I have not hit the monthly limit.  opencode go that look generous in the marketing copy often have a rate limit problem waiting.The 5-hour limit on GLM-5.1 is the binding constraint. On heavy pipeline days, I hit the 880-request cap about four hours in and switch to DeepSeek V4 Flash for the remaining hour.<\/p>\n<figure class=\"wp-block-image aligncenter size-large\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-pricing-1.webp\" alt=\"free ai providers 2026 - pricing illustration\" width=\"1024\" height=\"768\" class=\"wp-image-1226\" srcset=\"https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-pricing-1.webp 1024w, https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-pricing-1-300x225.webp 300w, https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-pricing-1-768x576.webp 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<p class=\"wp-block-paragraph\">&#8212; Most reviews of opencode go skip the limits page.

DeepSeek V4 Flash is similarly cheap. The budget models are fast enough for classification, extraction, and lightweight code completion. The frontier models are necessary for multi-file refactoring, architecture design, and debugging complex codebases.<\/p>\n<figure class=\"wp-block-image aligncenter size-large\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-limits.webp\" alt=\"free ai providers 2026 - limits illustration\" width=\"1024\" height=\"768\" class=\"wp-image-1227\" srcset=\"https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-limits.webp 1024w, https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-limits-300x225.webp 300w, https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-limits-768x576.webp 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<p class=\"wp-block-paragraph\">&#8212; opencode go is a practical choice for most setups.<\/p>\n<h2 class=\"wp-block-heading\" id=\"caching-cheaper-tokens-across-the-board\">Caching: Cheaper Tokens Across the Board<\/h2>\n<p class=\"wp-block-paragraph\">OpenCode Go supports prompt caching on most models. The cached token pricing is dramatically cheaper than uncached:<\/p>\n<li>GLM-5.1: $0.26 per 1M cached read (vs $1.40 regular input \u2014 81% cheaper)<\/li>\n<li>GLM-5: $0.20 per 1M cached read (80% cheaper)<\/li>\n<li>Kimi K2.6: $0.16 per 1M cached read (83% cheaper)<\/li>\n<li>Kimi K2.5: $0.10 per 1M cached read (83% cheaper)<\/li>\n<li>MiMo-V2.5: $0.0028 per 1M cached read \u2014 that is $0.28 per 100 million tokens. Effectively free.<\/li>\n<p class=\"wp-block-paragraph\">The cache write cost exists on some models (MiniMax M3 charges $0.75 per 1M for cache writes, MiniMax M2.7 charges $0.375), but the read cost is always cheaper than the regular input cost.  When opencode go change their limits, the difference is whether you noticed the change in the docs or in production.For repetitive coding tasks \u2014 the same system prompt, the same tool definitions, the same project context across multiple requests \u2014 the cache discount adds up fast.<\/p>\n<figure class=\"wp-block-image aligncenter size-large\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-caching-2.webp\" alt=\"free ai providers 2026 - caching illustration\" width=\"1024\" height=\"768\" class=\"wp-image-1228\" srcset=\"https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-caching-2.webp 1024w, https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-caching-2-300x225.webp 300w, https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-caching-2-768x576.webp 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<p class=\"wp-block-paragraph\">The Go docs show per-model caching estimates.  Most reviews of opencode go skip the limits page. The limits page is the actual product.For GLM-5.1, the typical usage pattern assumes 700 input tokens, 52,000 cached tokens, and 150 output tokens per request. That ratio means the cache is doing heavy lifting \u2014 the system prompt and tool definitions are cached across requests, and only the variable user query is counted as fresh input.<\/p>\n<p class=\"wp-block-paragraph\">&#8212; When opencode go change their limits, the difference is whether you noticed the change in the docs or in production.<\/p>\n<h2 class=\"wp-block-heading\" id=\"go-vs-zen-flat-subscription-vs-pay-as-you-go\">Go vs Zen: Flat Subscription vs Pay-As-You-Go<\/h2>\n<p class=\"wp-block-paragraph\">OpenCode Zen is the pay-as-you-go alternative to Go.  This is where opencode go becomes essential.Zen uses the same curated model list but charges per token at the rates listed above. You add a $20 balance (plus a $1.23 card processing fee) and it deducts as you use.<\/p>\n<figure class=\"wp-block-image aligncenter size-large\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-code.webp\" alt=\"free ai providers 2026 - code illustration\" width=\"1024\" height=\"768\" class=\"wp-image-1229\" srcset=\"https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-code.webp 1024w, https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-code-300x225.webp 300w, https:\/\/howtomake.best\/my_website4\/wp-content\/uploads\/2026\/06\/free-ai-providers-code-768x576.webp 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<p class=\"wp-block-paragraph\">Go is better if your usage is consistent and high enough that $10\/month is cheaper than the per-token equivalent.  When opencode go change their limits, the difference is whether you noticed the change in the docs or in production.Zen is better if your usage is sporadic \u2014 a few hundred requests per month, or bursty workloads that you want to pay for only when you use them.<\/p>\n<p class=\"wp-block-paragraph\">The break-even point depends on the model.  If you are evaluating opencode go in 2026, the free tier is the only one that matters for prototyping.For DeepSeek V4 Flash, at ~$0.50 per million tokens all-in, you would need to process about 20 million tokens per month for Go to beat Zen on cost. For GLM-5.1 at $5.80 per million tokens all-in, about 1.7 million tokens makes Go cheaper.<\/p>\n<p class=\"wp-block-paragraph\">In practice, if you use Go for more than a few hours per week, the subscription is cheaper.  This is exactly the kind of opencode go setup I would build for myself.If you use it occasionally for specific projects, Zen is cheaper. Both use the same API key system and the same model catalogue.<\/p>\n<p class=\"wp-block-paragraph\">&#8212; opencode go is a practical choice for most setups.<\/p>\n<h2 class=\"wp-block-heading\" id=\"how-i-use-opencode-go-in-production\">How I Use OpenCode Go in Production<\/h2>\n<p class=\"wp-block-paragraph\">I use Go as the second tier in my routing layer, after Ollama Cloud and before the individual provider free tiers.

If the task is vision, Google AI Studio gets it. Go sits in the middle \u2014 reliable, capable, not the fastest, not the cheapest, but the broadest model selection in one subscription.<\/p>\n<p class=\"wp-block-paragraph\">The Go API is OpenAI-compatible.

OpenCode itself supports Claude, GPT, and Gemini through your own API keys.<\/p>\n<p class=\"wp-block-paragraph\">If your budget is $0, Go is not free.  This is exactly the kind of opencode go setup I would build for myself.The free tier models on Ollama Cloud, Google AI Studio, and Mistral La Plateforme cover coding tasks at zero cost, albeit with lower rate limits and smaller model selection. Go is the upgrade path \u2014 $10\/month for reliable access to fourteen coding models with predictable limits.<\/p>\n<p class=\"wp-block-paragraph\">&#8212; This is exactly the kind of opencode go setup I would build for myself.<\/p>\n<h2 class=\"wp-block-heading\" id=\"comparison-opencode-go-vs-individual-provider-free-tiers\">Comparison: OpenCode Go vs Individual Provider Free Tiers<\/h2>\n<p class=\"wp-block-paragraph\">The table below compares Go to the free tier coding models from the providers covered in the rest of this deep dive series. opencode go that look generous in the marketing copy often have a rate limit problem waiting.<\/p>\n<figure class=\"wp-block-table is-style-stripes\">\n<table>\n<thead>\n<tr>\n<td class=\"wp-block-table-column\">Feature<\/td>\n<td class=\"wp-block-table-column\">OpenCode Go ($10\/mo)<\/td>\n<td class=\"wp-block-table-column\">Ollama Cloud (Free)<\/td>\n<td class=\"wp-block-table-column\">Mistral (Free)<\/td>\n<td class=\"wp-block-table-column\">DeepSeek (Free)<\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Coding models<\/td>\n<td>14 curated<\/td>\n<td>~8 open models<\/td>\n<td>codestral-2508, ministral<\/td>\n<td>DeepSeek V3<\/td>\n<\/tr>\n<tr>\n<td>Max context<\/td>\n<td>128K (GLM-5.1)<\/td>\n<td>Varies<\/td>\n<td>256K (codestral)<\/td>\n<td>128K<\/td>\n<\/tr>\n<tr>\n<td>Monthly cap<\/td>\n<td>$60 worth<\/td>\n<td>None (throttled)<\/td>\n<td>625K TPM<\/td>\n<td>Varies<\/td>\n<\/tr>\n<tr>\n<td>Rate limit<\/td>\n<td>$12\/5hr<\/td>\n<td>TPM-based<\/td>\n<td>TPM-based<\/td>\n<td>RPD-based<\/td>\n<\/tr>\n<tr>\n<td>Caching<\/td>\n<td>80-99% discount<\/td>\n<td>Provider-specific<\/td>\n<td>None on free tier<\/td>\n<td>None on free tier<\/td>\n<\/tr>\n<tr>\n<td>API key count<\/td>\n<td>1<\/td>\n<td>1<\/td>\n<td>1<\/td>\n<td>1<\/td>\n<\/tr>\n<tr>\n<td>Model count<\/td>\n<td>14<\/td>\n<td>~8<\/td>\n<td>2 coding models<\/td>\n<td>1 coding model<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n<p class=\"wp-block-paragraph\">Go does not win on any single dimension except model count and caching discount. What it wins on is combination: fourteen models, one key, predictable pricing, and caching that actually reduces cost. The individual free tiers are better at their specific strengths \u2014 Mistral is better at pure JSON output, Groq is faster for latency-critical tasks \u2014 but no single free tier gives you fourteen coding models behind one API key.<\/p>\n<p class=\"wp-block-paragraph\">&#8212;<\/p>\n<div id=\"rank-math-faq\" class=\"rank-math-block\">\n<div class=\"rank-math-list \">\n<div id=\"faq-1780752642743\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Do I need to use OpenCode the agent to subscribe to OpenCode Go?<\/h3>\n<div class=\"rank-math-answer \">\n<p>No. Go works as a standalone OpenAI-compatible API endpoint. Change your base URL to https:\/\/opencode.ai\/zen\/go\/v1 and use your Go API key. Any OpenAI-compatible client works \u2014 Python, TypeScript, curl.<\/p>\n<\/div>\n<\/div>\n<div id=\"faq-1780752642744\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What happens if I hit the $12 per 5-hour limit?<\/h3>\n<div class=\"rank-math-answer \">\n<p>The API returns rate limit errors until the window resets. Your subscription is not cancelled and you are not charged extra. You can top up credit to increase the limit, or wait for the next window.<\/p>\n<\/div>\n<\/div>\n<div id=\"faq-1780752642745\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Can I use OpenCode Go models for non-coding tasks?<\/h3>\n<div class=\"rank-math-answer \">\n<p>Yes, the API accepts any prompt. The models are benchmarked and selected for coding, but they work for general-purpose use. I use DeepSeek V4 Flash on Go for content classification and the quality matches the same model on other providers.<\/p>\n<\/div>\n<\/div>\n<div id=\"faq-1780752642746\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What is the difference between Go and Zen?<\/h3>\n<div class=\"rank-math-answer \">\n<p>Go is a flat $10\/month subscription with usage budgets ($12\/5hr, $30\/week, $60\/month). Zen is pay-as-you-go \u2014 add a $20 balance, pay per token at the listed rates. Go is better for consistent usage. Zen is better for sporadic usage.<\/p>\n<\/div>\n<\/div>\n<div id=\"faq-1780752642747\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Does OpenCode Go have a referral program?<\/h3>\n<div class=\"rank-math-answer \">\n<p>Not a formal one. The referral link gives new subscribers a standard signup flow. Use this link if you found this post useful. I pay for my subscription like everyone else.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p class=\"wp-block-paragraph\">&#8212;<\/p>\n<h2 class=\"wp-block-heading\" id=\"my-honest-recommendation\">My Honest Recommendation<\/h2>\n<p class=\"wp-block-paragraph\">If you write code and use more than two AI models, subscribe to OpenCode Go. The $10\/month is cheaper than managing three separate API accounts, tracking three sets of rate limits, and debugging three different caching implementations. Fourteen coding models behind one key is the right abstraction for 2026.<\/p>\n<p class=\"wp-block-paragraph\">If you write code occasionally and spend less than $10\/month on AI APIs, use Zen instead. Add a $20 balance once, use it when you need it, top up when it runs out. The per-token pricing is transparent and you only pay for what you use.<\/p>\n<p class=\"wp-block-paragraph\">If you do not write code at all, skip Go. The platform is optimised for coding agents and the model selection reflects that. Use the providers in my <a href=\"\/my_website4\/free-ai-providers-2026\/\" rel=\"noopener\"><a href=\"\/my_website4\/free-ai-providers-2026\/\">free AI providers guide<\/a><\/a> for general-purpose work.<\/p>\n<p class=\"wp-block-paragraph\">If you subscribe through my referral link at <a href=\"https:\/\/opencode.ai\/go?ref=Y6JHBM01GN\" rel=\"noopener\" target=\"_blank\">opencode.ai\/go<\/a>, the first month is $5. If you prefer Zen, the same curated models are available pay-as-you-go. Either way, the setup takes five minutes and the API key works everywhere.<\/p>\n<p>Related: <a href=\"https:\/\/howtomake.best\/my_website4\/zero-budget-ai-business-guide\/\">zero-budget AI business guide<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>My .env file has a line that reads OPENCODE_GO_BASE_URL=https:\/\/opencode.ai\/zen\/go\/v1.
