Frequently Asked Questions
Honest answers to common questions about LLM APIs, pricing, and how to choose.
A "free" LLM API means you can make real API calls without entering a credit card or paying anything. This includes: (1) permanent free tiers with rate limits (like Google Gemini's 1M tokens/day), (2) new-user trial credits (like OpenAI's $5 or Anthropic's $5), and (3) free tiers on open-source models (like Groq's Llama access). We only list providers where the free tier lets you do meaningful development work — not "free trials" that expire after 7 days.
First-party APIs (like OpenAI, Anthropic, Google, DeepSeek) run their own models. They set the pricing, control the model capabilities, and handle the infrastructure. These tend to have the best-performing models and most reliable service.
Inference providers (like Groq, Together AI, Fireworks) host open-source models (like Llama, Mistral, Qwen) on their infrastructure. They offer competitive pricing, sometimes faster inference, and access to a wide variety of open-source models. The tradeoff is you're dependent on their infrastructure and model availability.

It depends on your priorities:
For cost-effective coding agents: DeepSeek V3 or R1 — excellent code quality at $0.0001-0.001/1K tokens.
For complex refactoring and architecture: Claude 3.7 Sonnet — best-in-class for extended coding sessions with 200K context.
For production reliability: OpenAI GPT-4o or o1 — most battle-tested, widest ecosystem.
For real-time autocomplete: Groq — fastest inference speeds, critical for latency-sensitive tools.

Most users follow this path:
1. Start with free tiers (Google Gemini, DeepSeek, Groq) for development and testing.
2. Move to pay-as-you-go when you need more capacity — DeepSeek is cheapest, Google Gemini offers good value, OpenAI and Anthropic for premium quality.
3. Consider a subscription if you want predictable costs and multimodal access. MiniMax's Token Plan is notable for covering text, image, video, and audio under one subscription.
The "right" answer depends on your volume, required modalities, and quality needs. Our paid API guide has detailed comparisons.

No. We don't claim a discount is available unless we've verified it. When we feature a provider link with a discount (like the MiniMax 10% off link), it's because we have reason to believe it's currently active — but discounts can expire or change.
Always check the provider's pricing page directly for the most current offers. We clearly note when a discount may be available and include a disclaimer near any affiliate links.

We verify provider data monthly, or sooner if a provider announces pricing changes. Every provider entry shows a "Last checked" date so you know how current the information is.
LLM API pricing changes frequently — a provider that was expensive 6 months ago might be much cheaper now. We do our best to keep up, but we recommend checking official provider documentation directly for the most accurate current pricing.

Our rankings are based on transparent, weighted criteria — not on which providers pay us the most or pressure us to rank them highly. We may earn affiliate commissions from some featured providers, but this doesn't affect our editorial rankings.
We believe in being upfront about affiliations: our methodology page explains exactly how we score, and we clearly disclose when a link may earn us a commission. Our goal is to be genuinely useful to builders — that means giving honest recommendations even when it means NOT recommending something.

This guide focuses on individual developers and small teams. For enterprise requirements like HIPAA compliance, SOC 2, SSO, private networking, or custom model fine-tuning, the main options are:
Azure OpenAI: Best for Microsoft ecosystem shops, enterprise SSO, and compliance certifications.
AWS Bedrock: Best for AWS-native environments and multi-provider access through a single API.
Anthropic (direct): Strong enterprise features, including enterprise-focused access controls and stronger privacy commitments.
These enterprise options are beyond the scope of this comparison, which focuses on developer-centric pricing and experience.
