Pricing
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.
FreemiumThe Gemini API uses a three-tier structure. Free is for developers and small projects, offering limited access to select models with free input and output tokens, Google AI Studio access, and no billing account required, though content is used to improve Google's products. Paid unlocks higher rate limits for production, context caching, the Batch API (roughly 50% cost reduction), access to Google's most advanced models, and a guarantee that content is not used to improve Google's products. Pricing is billed per million tokens and varies by model: for example, Gemini 3.1 Pro Preview costs $2.00 input and $12.00 output per million tokens for prompts under 200K tokens, while cost-efficient options like Gemini 3.5 Flash-Lite start as low as $0.30 input and $2.50 output per million tokens, with additional Flex and Priority billing modes available for different latency and cost tradeoffs. Enterprise is for large-scale deployments through the Gemini Enterprise Agent Platform, adding dedicated support channels, advanced security and compliance certifications (HIPAA, SOC 2, FedRAMP), provisioned throughput, volume-based discounts, and MLOps tooling, available by contacting Google's sales team.

Summary
High-performance training and inference platform for open-source AI models
Build with Google's multimodal Gemini models via API and AI Studio
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
Google Gemini API Pros & Cons
Pros
- Genuinely native multimodal models covering text, image, video, and audio in one API
- Google AI Studio offers a real, usable free prototyping environment with no billing account required
- Google Search and Google Maps grounding help reduce hallucinations with live information
- Batch API and Flex pricing modes offer substantial cost savings for non-latency-sensitive workloads
- Clear upgrade path from free prototyping to enterprise-grade deployment via the Gemini Enterprise Agent Platform
Cons
- Pricing structure is complex, with per-model, per-mode (Standard/Batch/Flex/Priority) rates that require careful reading to estimate real costs
- Free tier usage is used to improve Google's products, so privacy-sensitive projects need to upgrade to the Paid tier for that guarantee to apply
- Frequent model churn (previews, deprecations, shutdown dates) means integrations need occasional migration work to stay current
- Full enterprise-grade features like fine-tuning, VPC Service Controls, and CMEK live on the separate Gemini Enterprise Agent Platform, not the Developer API itself
- Advanced capabilities like Computer Use and some agent tooling remain in preview with more restrictive rate limits
