## 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

## Subex

Subex is a long-established telecom software vendor that has repositioned itself around an AI-first approach. The site describes the company as an AI-native provider helping operators move from reactive processes to predictive and autonomous assurance, and it leans heavily on a theme of "fearless, seamless, fraud-free" operations. The core promise is simple: detect revenue leakage, fraud and partner exceptions early, explain why they happened, and either fix them automatically or escalate a clear recommendation to a specialist.

The product surface is broad and telecom-specific. FraudZap covers the major fraud families operators face today — bypass, SMS, handset, mobile money, MVNO, subscription and roaming fraud, CLI spoofing, robocalling and artificially inflated traffic. The assurance portfolio handles revenue, margin, cost, migration and regulatory assurance, plus adjacent areas such as order management, collections, financial reporting and CX assurance. A third pillar handles ecosystem management: partner lifecycle, digital services and IoT/M2M billing, wholesale and interconnect billing, settlement, dispute management, route optimisation and roaming. AI Agent Squads and dedicated agents (fraud investigative, PEM, business assurance) sit across these workflows.

Subex emphasises scale and longevity: over 30 years of innovation, customers in more than 110 countries, 200 billion-plus CDRs processed in a single instance, and roughly 60 percent of customers staying more than eight years. Pricing is not published and the company sells through demos, which is typical for enterprise telecom software. Deployment is designed to sit alongside existing platforms rather than replace them, with agents operating inside configured guardrails and keeping specialists in control of consequential decisions.

**Pricing & Plans:** Contact for Pricing. Subex does not publish rates or self-serve plans; pricing is quoted per engagement after a demo request, based on the modules selected and the scale of the operator's network and subscriber base.

- **FraudZap fraud management:** FraudZap covers bypass fraud, SMS fraud, handset and mobile money fraud, subscription and roaming fraud, CLI spoofing, robocalling and artificially inflated traffic.
- **Business assurance suite:** Revenue, margin, cost, migration and regulatory assurance identify leakage and service or experience risks before they reach customers.
- **Agentic AI squads:** AI Agent Squads reason across evidence, execute configured checks, package supporting evidence and recommend actions with human oversight and audit trails.
- **Partner ecosystem management:** Replace email-and-spreadsheet partner operations with digital onboarding, offer design, order flows, settlements and reconciliation across B2B2X chains.
- **Billing and settlement:** Billing and settlement for wholesale, interconnect, roaming, IoT/M2M, digital services, content and enterprise, plus telecom-specific collections and payments.
- **Managed and advisory services:** Business consulting and managed services to run assurance, fraud and partner operations on the customer's behalf.

**Strengths:** Deep telecom domain coverage from fraud to billing to partner management; Agentic AI investigates cases and provides audit trails rather than only summarising; Human-in-the-loop design keeps specialists approving consequential actions; Long track record with operators in more than 110 countries

**Limitations:** Enterprise pricing is not published; buyers must go through a demo and sales cycle; The platform is highly specialised for telecom operators, so it is not relevant to general businesses; Overlapping product names (multiple FraudZap and assurance modules) can be confusing when scoping a deployment; Full value depends on integrating with existing BSS, OSS and billing systems, which is a sizeable implementation effort
