## 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

## Use AI

Use AI positions itself as a single AI workspace rather than yet another chatbot. Instead of paying for three or four separate subscriptions and remembering which model is best at what, you get a unified chat surface where Claude, GPT, Gemini, Grok, DeepSeek, Kimi, Qwen, GLM and Meta models all live behind one prompt box. The company is explicit that it simply provides access to third-party models and is not affiliated with any of the providers, so what you are buying is convenience and consolidation rather than a proprietary model.,Around that core chat there is a fuller productivity layer. You can create documents, PDFs, slide decks and spreadsheets from natural-language prompts, generate images with current image models, and run Deep Research jobs that read across dozens or hundreds of web sources to produce cited reports. Projects and knowledge bases keep related conversations and files together, a file library stores your uploads, and 100+ app connectors let the assistant pull in or act on data from tools you already use. Memory and context are carried between sessions, scaling from a limited allowance on the free tier to maximum on Max.,Pricing is straightforward and published: a genuinely usable free tier with no credit card, Pro at $19.99 per month, and Max at $116.99 per month with 5x the usage allowance, maximum reasoning effort and access to the most exclusive models. Premium model usage is metered by a daily-applied monthly allowance, with an unlimited 'Use AI Instant' chat mode available on paid plans under fair use. If your work involves constantly switching between frontier models, that consolidation is the main draw.

**Pricing & Plans:** Freemium with a free trial-style free tier. Free: $0 with generous everyday chat, limited web search and web, iOS and Android access, no credit card required. Pro: $19.99/month (billed quarterly at $59.97) for unlimited Use AI Instant messaging, premium model access, projects, image generation and Deep Research. Max: $116.99/month (billed quarterly at $350.97) with 5x the usage allowance, maximum reasoning and Deep Research. Prices vary by country and promotion.

- **Many frontier models in one app:** Switch between Claude, GPT, Gemini, Grok, DeepSeek, Kimi, Qwen, GLM and Meta Muse models without juggling separate subscriptions.
- **Switch models mid-chat:** Start a conversation on a fast model and hand the same thread to a stronger reasoning model when the task gets harder, keeping context intact.
- **Deep Research with citations:** Run multi-source research that reads up to 200 sources on Pro and up to 1,000 on Max, returning structured reports with references.
- **Documents, slides and sheets:** Create PDFs, slide decks and spreadsheets directly from a prompt, and generate images with leading models such as Nano Banana and GPT Image.
- **Connectors, projects and memory:** Link 100+ external apps, organise work into projects and knowledge bases, and keep long-term memory and context across sessions.

**Strengths:** One subscription and one interface replaces several separate model subscriptions; Free tier is genuinely usable with no credit card required; Model switching mid-conversation keeps context when you escalate to a stronger model; Built-in document, slide, sheet and image generation alongside chat

**Limitations:** You are limited to whichever models the platform has integrated; you cannot plug in arbitrary API keys for every model; Premium model access is metered by a monthly allowance, so heavy users on Pro can run out; Because it resells frontier models, availability of specific named models can change without notice; No self-hosting or on-premise option for teams that need data to stay in-house
