Compare providers
Two providers can offer the same model or the same virtual machine at very different all-in cost once credits, free tiers and billing rules are counted. These comparisons tell you which console to open first for your kind of project, and why.
vs 
Anthropic vs Gemini API when the bill is mostly repeated context Pick Anthropic for agent and chat workloads that reread the same long context, because cache reads are a twentieth of input price and don’t count toward rate limits. Pick the Gemini API for prototypes, classrooms and high-volume cheap classification, where the free tier and $0.10 Flash-Lite win. Teams with privacy obligations should stay on paid tiers of either, since only Gemini’s free tier feeds product improvement. Winner: Tie 
vs 
AWS vs Azure for Free Credits, Startup Programs and Small VM Pricing AWS is the safer start for a developer who wants to try services without a card and without a 30-day deadline. Azure is the better home for a team on Microsoft 365 and Entra ID, or anyone who wants a year of free B1s VM hours and a spending limit that stops charges on its own. Investor-backed startups should take whichever program their investor is affiliated with, since both top tiers require a referral. Winner: Tie 
vs DigitalOcean vs AWS on Free Credits, Droplet Pricing and Startup Programs Choose AWS if you want $200 of credits to experiment with, need a specific managed service, or expect to apply for Activate through an investor. Choose DigitalOcean if you’re running a web app or API on a few servers and want a bill that matches the published price, outbound bandwidth included. Hobby projects and small SaaS teams usually spend less on DigitalOcean. Anything built on Lambda, DynamoDB or Bedrock belongs on AWS. Winner: AWS vs 
Gemini API vs OpenAI for developers who want free usage first Choose the Gemini API if you’re testing, teaching or building something that can live inside free Flash limits, or if you’re a VC-backed startup that can apply for Google Cloud credits worth up to $250,000 in year one. Choose OpenAI if you need stable long-term pricing, since Gemini has two scheduled increases on the books, or if your rate limit needs outgrow Tier 1 faster than $100 of spend can raise them. Winner: Gemini API 
vs Google Cloud vs AWS on Free Credits, Free Tiers and Startup Programs Pick Google Cloud if you want the larger trial, a free tier with no end date, and the richer AI startup package. Pick AWS if you need the widest service catalog, want to test without a card on file, or your investor is an Activate Provider. A solo developer with a weekend project should start on Google Cloud. A team that already knows EC2 and IAM should stay on AWS and apply for Activate. Winner: Google Cloud vs Google Cloud vs Azure on Free Credits, Startup Programs and Billing Rules Google Cloud is the better trial for a developer who wants three months to test without pressure. Azure is better if you’ll stay on Microsoft identity, want 12 months of free B-series VM hours, or are a startup that needs a card-backed sponsorship subscription that converts to pay-as-you-go without downtime. Funded startups get more from Google. Pre-funding founders get a faster first credit from Microsoft. Winner: Google Cloud vs Google Cloud vs DigitalOcean for Free Credits, Free Tiers and Monthly Cost Pick Google Cloud if you want $300 to test with, plan to use BigQuery, Cloud Run or Gemini, or have raised a round that qualifies for the startup program. Pick DigitalOcean if you’re deploying a web app, API or small database on a few servers and want the monthly bill to match the published price, bandwidth included. Students and side projects do fine on either. Funded AI startups should go to Google. Winner: Google Cloud vs OpenAI vs Anthropic API and which one costs less to run in 2026 Pick OpenAI if you need predictable rate limits from day one and a cheaper top-end model for occasional heavy calls. Pick Anthropic if your prompts carry long repeated context, because cached reads cost 5% of the input price on Sonnet 5.5 and don’t count toward rate limits. Teams already paying for a Claude Max or Team plan get monthly API credits that tip the balance toward Anthropic. Winner: Tie 
vs 
OpenRouter vs Groq for cheap and free inference Choose OpenRouter if you want one key and one prepaid balance across OpenAI, Anthropic, Google and dozens of open models, and you can live with a 5.5% fee on top-ups. Choose Groq if your workload fits GPT-OSS or Qwen, you want sub-dollar pricing with batch and caching discounts stacked on top, and you prefer postpaid invoicing. For a weekend project, OpenRouter’s free models are the easier start. Winner: OpenRouter 
vs xAI Grok API vs OpenAI API on price, limits and billing Choose xAI if output tokens dominate your bill, you want a 1 million token context at $1.25 input, or you need high request rates without a purchase history. Choose OpenAI if you need a batch API with a published 50% discount, a budget model under $1 per million output, or the larger ecosystem of tooling. For a venture-backed startup, both programs route through partners, and xAI’s is the one currently taking applications. Winner: Tie
