Pricing
PaidThe platform uses pay-as-you-go pricing for the tools, storage, and compute resources used, with new customers getting up to $300 in free credits. Generative AI pricing starts at $0.0001 based on image input, character input, or custom training pricing for Imagen models, and text, chat, and code generation starts at $0.0001 per 1,000 characters based on input (prompt) and output (response). Custom model training pricing is based on machine type used per hour, region, and any accelerators used, available via a sales estimate or the pricing calculator. Notebooks are billed at the same rates as Compute Engine and Cloud Storage, plus separate management fees based on region, instances, and notebooks used. Pipelines start at $0.03 per pipeline run based on execution charges and resources used. Vector Search pricing is based on data size, queries per second (QPS), and number of nodes used. A pricing calculator and custom quotes from sales are available for detailed cost estimates.
PaidFireworks AI's serverless inference is pay-per-token with postpaid billing and $1 in free starter credits, with per-model rates across Standard, Priority, and Fast tiers detailed in its documentation (e.g. GLM 5.2 at $1.40/M input and $4.40/M output tokens, MiniMax M3 at $0.30/M input and $1.20/M output tokens). Embeddings are priced by base model size, from $0.008 to $0.10 per 1M input tokens. Training is priced per 1M training tokens for supervised fine-tuning (SFT) and direct preference optimization (DPO): LoRA SFT ranges from $0.50 (models up to 16B parameters) to $10.00 (models over 300B), with Full Param SFT and DPO costing roughly 2-4x more depending on model size and method. Reinforcement fine-tuning is billed per GPU hour at on-demand rates. The Serverless Training API charges separately for prefill, cached prefill, sample, and train tokens (e.g. Qwen 3.5 9B at $0.66-$1.995 per 1M tokens depending on operation). On-demand GPU deployments are billed per GPU hour: $7.00 for H100 or H200, $10.00 for B200, $12.00 for B300, and $18.00 for GB300, with region-restricted (US/Europe) deployments priced at 1.5x standard rates. Reserved and enterprise capacity pricing is available by contacting sales.

Summary
Google's unified platform for AI agents, models, and MLOps
High-performance training and inference platform for open-source AI models
Google Cloud Vertex AI Pros & Cons
Pros
- Access to 200+ models including Gemini, Claude, and open models like Gemma in one platform
- Combines full MLOps lifecycle tooling with modern agent-building capabilities
- Agent2Agent (A2A) protocol support enables interoperability across different agent platforms
- Deep native integration with BigQuery and the broader Google Cloud ecosystem
- $300 in free credits for new customers to explore the platform
- Backed by Google's infrastructure and named a leader in multiple analyst reports
Cons
- Recently rebranded from Vertex AI to Gemini Enterprise Agent Platform, which can confuse teams referencing older documentation or tutorials
- Pricing is spread across many separate tools and services, making total cost estimation more complex than flat-rate competitors
- Custom model training costs require a sales estimate or pricing calculator rather than transparent self-serve rates
- Deep feature set and agent-first restructuring add a learning curve for teams new to the Google Cloud ecosystem
- Some advanced governance and enterprise features are gated behind Google Cloud sales conversations
Fireworks AI Pros & Cons
Pros
- Founded by former core PyTorch engineers with deep inference optimization expertise
- OpenAI and Anthropic-compatible API simplifies migration from closed-model providers
- Proprietary FireAttention and FireOptimizer deliver strong throughput and latency gains
- Full spectrum of training options from guided runs to fully custom RL loops
- Proven at massive scale, processing tens of trillions of tokens daily for 10,000+ customers
- Backed by major investors and used in production by Cursor, Notion, Vercel, and Quora
Cons
- Pricing is spread across serverless, on-demand, and training pages, requiring some effort to estimate total costs
- Region-restricted deployments in the US or Europe cost 1.5x standard on-demand rates
- Reserved and enterprise capacity requires contacting sales rather than transparent self-serve pricing
- Reinforcement fine-tuning billed per GPU hour can be harder to predict than flat per-token pricing
- Primarily focused on open-weight models, so access to fully closed frontier models is more limited
