## DeepSeek

DeepSeek (Hangzhou DeepSeek Artificial Intelligence Co., Ltd.) is a frontier AI research organization that disrupted the global LLM market by pairing open-weight transparency with breakthrough Mixture-of-Experts (MoE) and reinforcement-learning reasoning efficiency. Following the landmark releases of DeepSeek-V3 and the peer-reviewed DeepSeek-R1 reasoning model, DeepSeek introduced the DeepSeek-V4 generation in 2026—featuring a hybrid attention architecture and a native 1-million-token context window across DeepSeek-V4-Pro (1.6T total parameters, 49B active per token) and DeepSeek-V4.1-Flash (284B total parameters, 13B active per token).

Users can interact with DeepSeek in three ways: completely free through the consumer web portal (chat.deepseek.com) and mobile apps with one-click toggles for deep thinking and live web search; via DeepSeek's hosted, OpenAI-compatible developer API; or by self-hosting DeepSeek's open-weight checkpoints (including V3, R1, Prover-V2, and distilled Qwen/Llama variants) on private infrastructure. The models excel at competitive mathematics, algorithm design, repository-level software engineering, and structured data extraction, with automatic context caching on the API that slashes repeated prompt costs by over 95%.

In late 2026, DeepSeek remains the price-performance benchmark for developers and automation workflows. While the consumer chat interface remains free without a mandatory $20/month subscription tier, the developer API transitioned in late 2026 to two primary endpoints—`deepseek-flash` and `deepseek-v4-pro`—with time-of-day pricing. Off-peak API calls cost just $0.15 per million input tokens ($0.003 on cache hits) and $0.60 per million output tokens on Flash, and $0.66 input / $1.98 output on V4-Pro, making it a fraction of the cost of comparable Western frontier models.

**Pricing & Plans:** Free web and mobile chat app at chat.deepseek.com; pay-as-you-go OpenAI-compatible API with off-peak rates at $0.15/1M input ($0.003 cache hit) and $0.60/1M output for deepseek-flash (V4.1-Flash), and $0.66/1M input ($0.022 cache hit) and $1.98/1M output for deepseek-v4-pro (peak weekday UTC hours bill at 2x).

- **DeepSeek-V4 Hybrid Attention & 1M Context:** Leverages a sparse Mixture-of-Experts architecture (49B active parameters out of 1.6T on V4-Pro) to process up to 1 million tokens with minimal latency and memory overhead.
- **Transparent Chain-of-Thought Reasoning:** Pioneered by DeepSeek-R1 and integrated into V3.2 and V4 thinking modes, exposing step-by-step self-verification for complex math, logic, and code debugging.
- **Automatic Context Caching & Off-Peak API Pricing:** Drops input token costs to $0.003/1M on Flash and $0.022/1M on V4-Pro for cache hits, with 50% lower rates during off-peak UTC hours.
- **Free Consumer Web & Mobile Assistant:** Provides free access at chat.deepseek.com and on iOS/Android with document uploads, reasoning mode, and web search without paywalling core models.
- **Open-Weight Ecosystem & Self-Hosting Freedom:** Offers open weights for DeepSeek-V3, R1, Distill variants, and Prover models on Hugging Face and GitHub so enterprises can deploy within air-gapped environments.

**Strengths:** Completely free consumer web and mobile app with deep reasoning and web search included; Ultra-low API token rates ($0.15/$0.60 on Flash, $0.66/$1.98 on V4-Pro off-peak) with up to 98% savings on cached inputs; Drop-in OpenAI API compatibility makes switching or routing between models effortless; Strong open-weight lineage allows teams to self-host or fine-tune models without vendor lock-in

**Limitations:** Hosted API and web app store data on servers in China, prompting compliance restrictions for some Western enterprises and government agencies; Peak-hour API pricing (01:00–04:00 and 06:00–10:00 UTC on weekdays) doubles per-token costs compared to off-peak rates; Lacks native voice mode, video generation, and productivity suite integrations offered by ChatGPT and Google Gemini

## StackAI

. What StackAI is

StackAI is an enterprise AI agent platform aimed at IT and enterprise architecture teams. It provides the building blocks to turn a manual, time-consuming process into a working agent in minutes: a visual canvas for composing agents and multi-step flows, modules for storage, vision, text-to-speech and speech-to-text, and code steps in Python or JavaScript when you need custom logic.

Agents are only as useful as the systems they can touch, so the platform ships with 500+ enterprise integrations that let an agent read, write and execute tasks inside your existing CRM, ticketing, document and collaboration tools. Knowledge bases can be grounded in your own material through document upload, web scraping, Google Drive and Notion connectors, with readers for PDF, Word and PowerPoint. Because it is model-agnostic, each step can route to whichever LLM performs best for that job.

Governance is the differentiator. StackAI is certified to SOC 2 Type II, HIPAA, GDPR and ISO 27001, offers SSO, access control and audit logs, and supports human review at critical decision points. It can run multi-tenant, in your VPC or fully on-premise. The company announced that it has been acquired by Asana, adding human-agent workflow management to the picture. Pricing is a $0 Free plan with 500 runs per month, 2 projects and 1 seat, and a custom Enterprise tier for teams that need unlimited scale, dedicated engineers and regulated deployment options.

**Pricing & Plans:** StackAI has a $0 Free plan that includes 500 runs per month, 2 projects and 1 seat with community support. The Enterprise tier is custom-priced and includes a custom number of runs and seats, unlimited projects, all features and data loaders, dedicated infrastructure and solution engineers, on-premise and VPC deployment, access control, SSO, and SOC 2 / HIPAA / GDPR compliance.

- **No-Code Agentic Workflows:** Assemble agents and multi-step flows on a visual canvas with modules for agents, storage, vision, text-to-speech and speech-to-text, then add Python or JavaScript logic when you need it.
- **500+ Enterprise Integrations:** Connect agents to 500+ enterprise systems so they can read, write and execute tasks inside your CRM, helpdesk, document stores and collaboration tools.
- **Knowledge Bases and Data Loaders:** Ground agents in your own material with document upload, web scraping, Google Drive and Notion connectors, and document readers for PDF, Word and PowerPoint.
- **Security, Governance and Deployment Choice:** Deploy in multi-tenant cloud, your own VPC or on-premise, with SSO, role-based access control, audit logs and human review at critical decision points.
- **Model-Agnostic LLM Routing:** Choose the best-performing model for each step of a workflow instead of standardising on a single provider.
- **Ready-Made Agent Templates:** Pre-built agents for SOW intake, service desk replies, anti-money-laundering screening, call compliance extraction and internal L&D Q&A.

**Strengths:** Visual no-code builder gets agents from process to production quickly; 500+ enterprise integrations let agents act inside existing systems; Model-agnostic routing across leading LLMs; SOC 2 Type II, HIPAA, GDPR and ISO 27001 certifications

**Limitations:** Advanced capabilities such as on-prem, VPC deployment and SSO are Enterprise-only; The free plan is tight at 500 runs per month, 2 projects and a single seat; No public self-serve mid-tier pricing between Free and Enterprise; Enterprise focus means more setup and governance overhead than a lightweight automation tool
