Quick read
- Free with no card: Vercel AI SDK.
| Field | Replicatereplicate.com | Vercel AI SDKai-sdk.dev | Anthropic API / Claude Platformplatform.claude.com |
|---|---|---|---|
| What it is | A catalog of thousands of community and official models — image, video, audio, LLM — each behind one prediction API. It is an inference host: you push a Cog container or run someone else's, and billing is per second of GPU time or per generated output. | A TypeScript toolkit that gives every model provider one interface — generateText, streamText, structured object generation, tool calling — plus React, Svelte and Vue hooks for streaming UI. It supports 100+ models across 20+ providers; a Python version is in beta. | Anthropic's first-party API for the Claude models, plus the Agent SDK, tool use, MCP connectors, files and batch endpoints. This is a model provider, not a gateway — you get the models Anthropic trains and nothing else, with prompt caching and batch as the main cost levers. |
| Category | Model APIs, routers & observability | Model APIs, routers & observability | Model APIs, routers & observability |
| Cost tier | paid | free | paid |
| Pricing | Per second of compute (T4 $0.000225/s, A100 80GB $0.0014/s) or per output for media models (FLUX Dev $0.025/image, video from $0.09/s). Some LLMs bill per token. No free plan. | Free and open source. No cost beyond the model provider you call; Vercel AI Gateway usage is billed separately if you opt into it. | Per token. Opus 5 $5/$25 per M in/out; Sonnet 5 $2/$10; Haiku 4.5 $1/$5; Fable 5 and Mythos 5 $10/$50. Batch API 50% off; cache reads 0.1x input. |
| Why builders pick it | The fastest way to call a weird open model — a niche upscaler, a voice clone, a brand-new video model — without touching CUDA. Public models cost nothing when idle, so hobby projects sit at $0. | Swapping providers is a one-line change, and streaming chat UI that would take a day of SSE plumbing takes about ten lines. It is the default choice for anything Next.js shaped. | Best-in-class coding and agentic tool use, and the only place to get Claude with full feature support. Prompt caching at 0.1x read cost makes long system prompts and big codebase context genuinely affordable. |
| Watch out for | Private and dedicated models bill for boot and idle time, not just inference — a deployment left running overnight can cost more than a month of API calls. Cold starts on rare models take minutes. | Major versions have shipped breaking API changes, so older tutorials and AI-generated snippets often will not compile — check which version an example targets before copying it. | Output tokens cost 5x input, and extended thinking bills as output — a reasoning-heavy agent loop can 10x your bill versus the naive estimate. Tier-based rate limits throttle new accounts hard. |
| How to wire it up | pip install replicate (or npm i replicate) | npm i ai | npm i @anthropic-ai/sdk (or pip install anthropic) |

Prefer the free tier when no budget was stated, and say what the ceiling is. 2. Read the full dossier before integrating. 3. Fetch /api/public/models before writing any AI model ID.
