Gemini Free

Google offers the most generous free tier among Western AI providers. You get access to Gemini 3.1 Pro with usage limits that reset daily. The free tier includes image generation, Google search integration, and a reasonable context window. For most casual users, Gemini's free plan covers daily needs. It's fast (120.4 t/s on the paid tier, slightly slower on free) and handles most tasks well.

Admix Free

Admix Free gives you 20 free credits per day on eligible free models. Paid plans unlock GPT-5.4, Claude, Gemini, and the rest of the 350+ model catalog. The free allowance is meant for a practical test before choosing a plan.

ChatGPT Free

ChatGPT's free tier gives limited access to GPT-5.4. The usage caps are tighter than Gemini's, and some features (like computer use and full image generation) are restricted. Still, for basic Q&A, writing help, and simple coding, it works. If you hit the free limit, ChatGPT Go at $8/month with GPT-5.2 Instant is the cheapest upgrade.

Claude Free

Claude's free tier has the tightest limits among the big three. You get access to Sonnet 4.6 with very limited daily messages. The quality is excellent when you can use it, but you'll hit the cap quickly. If you write code or long documents, the free tier won't last through a work session.

DeepSeek Free

DeepSeek offers a generous free tier with their V4 model (~1T parameters). It's particularly strong for coding tasks, matching frontier models on code benchmarks. The trade-off is that it's a Chinese provider, which may matter for privacy-sensitive users. For coding work, it's one of the best free options available.

Budget Alternatives ($8/month)

If free tiers aren't enough, the cheapest paid options are:

• ChatGPT Go: $8/month for GPT-5.2 Instant + image generation
• Admix Starter: $10/month (or $8/month billed annually) for 500 credits/month across 350+ AI models

Both are half the price of premium subscriptions and cover most daily use cases.

My Recommendation

Start with Admix Free to try different models and find what works for your use case. Supplement with Gemini Free for Google-integrated tasks and DeepSeek for coding. If you outgrow free tiers, Admix Starter at $10/month (or $8/month billed annually) is the best value upgrade.
