Synthetic.new Pricing With the $10 Free Credit
Synthetic.new uses flat-rate pricing starting at $30/month per pack, and the $10 referral credit lowers your effective first-month cost across every plan. Unlike per-token APIs where your bill grows with usage, you pay one predictable price regardless of how many tokens your agents consume on included models.
| Plan | Normal Price | With $10 Referral Credit | Effective First Month | Savings |
|---|---|---|---|---|
| 1 Pack (Standard) | $30/mo | $10 credit applied | $20/mo | $10 off |
| 2 Packs | $60/mo | $10 credit applied | $50/mo | $10 off |
| 3 Packs | $90/mo | $10 credit applied | $80/mo | $10 off |
The credit is applied automatically through the invite link — there’s nothing to type. Each additional pack scales your rate limits and concurrency linearly, so heavier workloads can simply stack packs while keeping costs flat and predictable.
The Problem: Why Per-Token API Billing Hurts AI Developers
Pay-per-token pricing is brutal for anyone running modern AI coding agents. Agentic workflows loop through reasoning, tool calls, and context re-reading repeatedly, and each pass burns tokens. The result is bills that are impossible to forecast and frequently shocking.
The data backs this up:
Agentic tasks consume up to 1,000× more tokens than standard code reasoning and code chat, with input tokens dominating the cost. Source: How Do AI Agents Spend Your Money? (arXiv)
The core challenges developers face with traditional APIs:
- Unpredictable bills – A single agent can consume 10× to 1,000× more tokens per task than a single prompt.
- Token burn from loops – Agents re-read context and retry, multiplying consumption silently.
- Surprise charges – Background agentic runs accumulate large bills before anyone notices.
- Hidden CI/CD costs – Agents triggered on every pull request quietly rack up usage.
- Budget anxiety – Teams hesitate to run agents aggressively for fear of cost overruns.
Agentic Workflows Multiply Your Token Spend
The deeper an agent reasons, the more it costs. Analysis shows a single agent can consume 10x to 1,000x more tokens per task than a one-shot prompt, depending on workflow complexity.
An agent consuming roughly 100 tokens per second at about $4 per million tokens costs around $1.50 per hour to operate — and that compounds fast across parallel runs. Source: Forbes — Agentic AI’s Token Paradox
Hidden Costs in Automated Pipelines
Agents that run on every pull request can quietly accumulate large API bills, as documented by GitHub’s own engineering team. When billing is tied to consumption, every automated trigger is a line item — and they add up invisibly.
The Solution: Flat-Rate AI API Access With Synthetic.new
Synthetic.new solves the token-burn problem by charging one flat monthly rate with zero per-token costs for included models — your bill stays the same whether you run one prompt or run agents around the clock. This is the fundamental difference that makes it a genuine cheap OpenAI API alternative for heavy users.
| Traditional Per-Token API | Synthetic.new Flat-Rate Subscription |
|---|---|
| Bill grows with every token | Fixed monthly price |
| Unpredictable agentic costs | Zero per-token charges for included models |
| Surprise overage charges | Predictable, capped billing |
| Standard rate limits | 3× the rate limits of Claude’s $20/mo plan |
| Data may be used for training | Private inference — never trained on your data |
| Single plan ceiling | Stack packs to scale linearly |
Always-On Open-Source Models
Synthetic.new runs leading open-source models privately and includes them in your subscription with no per-token charges:
- GLM-5.1 – Strong general-purpose and coding performance
- DeepSeek-R1 – Advanced reasoning at scale
- Qwen3.5 – Versatile multilingual and coding capability
- MiniMax-M2.5 – High-throughput inference

Drop-In Compatible Endpoints
Because the service exposes OpenAI-compatible and Anthropic-compatible endpoints, switching is a swap-in replacement. You change a base URL and key — your existing code keeps working. According to industry comparisons of LLM API pricing models, this compatibility is exactly what lets developers escape per-token billing without rewriting their stack.
Higher Rate Limits, Lower Friction
Each pack delivers 500 requests per 5 hours — roughly 3× the rate limits of Claude’s standard $20/month plan. Need more headroom? Add packs to scale rate limits and concurrency linearly.
