## Doubleword

Doubleword is an inference provider that runs popular open-weight models on its own optimized stack rather than reselling a hyperscaler's endpoints. It positions itself for teams whose workloads are token-hungry — agent loops, document extraction, dataset annotation, evaluation runs, and other pipelines that call models millions of times — and who therefore care more about throughput and cost per token than about cutting-edge single-shot reasoning.

A distinctive part of the offering is latency-based pricing: the same model is available at different speeds, so users choose a realtime tier for interactive requests, an async tier that trades some latency for lower cost, or a 24-hour batch tier for jobs that can wait. All tiers are billed by tokens, with prepaid credits on the self-service plan. Doubleword also advertises prompt caching, tool calling, structured outputs, and zero data retention as standard.

For heavier or regulated workloads, the company offers dedicated deployments with guaranteed high-throughput capacity and no rate limits, custom model hosting, region-locked processing (for example US- or EU-based inference), signed agreements, and engineering support. The platform is built around OpenAI-compatible APIs, so existing code and agent frameworks can be pointed at it with minimal changes.

**Pricing & Plans:** Self-service inference is pay-as-you-go with prepaid credits and no subscription. Dedicated inference is quoted separately and includes volume pricing. Rather than fixed plans, cost depends on the model, the chosen speed tier, and prompt/response lengths.

- **Latency-based speed tiers:** Run the same model in realtime, async, or 24-hour batch mode and pay less the longer the job can wait.
- **OpenAI-compatible API:** Point existing SDKs and agent code at Doubleword with minimal changes, using prompt caching, tool calling, and structured outputs.
- **Access to major open-weight models:** Use leading open-weight text, coding, math, and vision language models through one endpoint and one billing relationship.
- **Dedicated high-throughput capacity:** Reserve optimized infrastructure for sustained real-time traffic without rate limits, with workload-specific tuning.
- **Zero data retention:** Zero Data Retention is included by default, and region-locked processing is available for compliance-driven deployments.

**Strengths:** Latency-based tiers give a genuine lever for cutting inference cost; OpenAI-compatible interface keeps migration effort low; Dedicated options cover high-volume and compliance-sensitive deployments; Zero Data Retention is included rather than sold as an add-on

**Limitations:** No fixed published price plans, so budgeting needs usage estimates; Dedicated capacity requires a sales conversation and a commitment; Model catalog trails the largest closed-model providers on frontier capabilities

## FlexAI

FlexAI sits one layer above both model APIs and raw GPU clouds. Instead of stopping at a single inference call or a bare compute rental, it offers a managed path from the first API key to fully private AI infrastructure. Token Factory serves 30+ open models — text, code, vision, embeddings, image, speech and video — behind one OpenAI-compatible endpoint, so most applications migrate simply by changing a base URL. AgentOS adds an agent runtime connected to company context and tools, with scoped memory, approvals and an audit trail.

For teams that outgrow shared endpoints, FlexAI offers Dedicated GPUs for VMs, fine-tuning and production inference on FlexAI-operated NVIDIA, AMD and Tenstorrent fleets, plus AI Factory for VPC, on-premises and air-gapped deployments. The platform emphasises zero data retention: prompts and outputs are not stored and never train any model, alongside SOC 2 Type II and GDPR alignment and an EU data option.

Pricing is transparent and usage-based on the serverless lane — per token for text, and per image, per million characters of speech, per minute of audio or per minute of generated video for media models — while dedicated capacity and private deployments are quoted per engagement. A startup program offers credits and discounts on dedicated capacity.

**Pricing & Plans:** Pay-as-you-go serverless pricing (per token for text; per image, audio or video minute for media) with a free playground, plus dedicated GPU and private-cloud plans quoted on request. Startup credits and discounts available.

- **OpenAI-compatible model API:** One API key and a drop-in OpenAI SDK replacement unlock 30+ open models across text, reasoning, coding, vision, embeddings, speech-to-text, text-to-speech, image and video.
- **AgentOS agent runtime:** Run agents connected to company context and tools with scoped memory, tool permissions, human approvals and an auditable decision trail.
- **Dedicated GPUs and fine-tuning:** Reserve NVIDIA, AMD or Tenstorrent capacity for VMs, fine-tuning and production inference when shared serverless endpoints are not enough.
- **Private and sovereign deployment:** AI Factory supports VPC, on-premises and air-gapped installs, with zero data retention, an EU option, SOC 2 Type II and GDPR alignment.
- **No-signup playground:** Try image generation and chat completions directly in the browser before creating an account, on the same API you would use in production.

**Strengths:** Single OpenAI-compatible endpoint across text, vision, code, embeddings, speech, image and video models; Clear path from serverless inference to dedicated GPUs to private or air-gapped clouds; Zero data retention by default with SOC 2 Type II, GDPR alignment and an EU option; Governed agent runtime with approvals, audit trails and scoped memory

**Limitations:** Serverless rates are repriced against the market, so budgets need periodic review; Dedicated and private deployment pricing is quote-based rather than published; The broad catalogue means teams still need to benchmark model quality for their own tasks
