Frequently Asked Questions

What is the cheapest LLM API in 2026?

DeepSeek V3 is the cheapest high-quality LLM API at $0.27 per million input tokens and $1.10 per million output tokens. For even lower costs, Gemini 2.5 Flash offers $0.075/$0.30 per million tokens. Access both through SkillBoss with zero markup at api.skillboss.co/v1.

How does LLM API pricing work?

LLM APIs charge per token (roughly 4 characters = 1 token). Pricing is split into input tokens (your prompt) and output tokens (the response). Costs are quoted per million tokens. For example, Claude Sonnet costs $3/M input and $15/M output tokens.

How does SkillBoss LLM API pricing compare to OpenRouter?

SkillBoss passes through provider pricing with zero markup, same as OpenRouter. The key difference: SkillBoss includes 100+ non-LLM APIs (image generation, video, scraping, email, search) alongside LLMs — all through one API key. OpenRouter is LLM-only.

Can I use one API key for all LLM models?

Yes. SkillBoss provides a single OpenAI-compatible API key that works with Claude, GPT, Gemini, DeepSeek, Llama, Mistral, and 100+ other models. Set base_url to api.skillboss.co/v1 in Claude Code, Cursor, Windsurf, or any OpenAI-compatible client.

Is there a free LLM API?

SkillBoss offers free credits on signup so you can test any model before committing. DeepSeek and Gemini Flash are the most cost-effective options for production use, costing less than $1 per million tokens.

How is LLM API pricing calculated?

LLM API pricing is calculated per token, where one token is roughly 4 characters or 0.75 words. Providers charge separately for input tokens (your prompt) and output tokens (the response), quoted per million tokens. For example, GPT-4o costs $2.50 per million input tokens and $10 per million output tokens. SkillBoss shows all prices transparently with zero markup.

What is the cheapest per-token LLM?

Gemini 2.5 Flash is the cheapest high-quality LLM at $0.075 per million input tokens and $0.30 per million output tokens. DeepSeek V3 offers the best value for coding at $0.27/$1.10 per million tokens. Both are available through SkillBoss with zero markup.

Does SkillBoss add markup?

No. SkillBoss passes through provider pricing with zero markup — you pay the exact same per-token rate as going directly to each provider. The difference is you get one API key for 100+ models instead of managing separate accounts with each provider.
