## 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

## PromptLocker

PromptLocker targets a problem that regulated practices already have: staff quietly pasting client files, tax records or patient information into consumer AI tools. Instead of trying to ban those tools, PromptLocker provides a sanctioned alternative. The governance layer is deployed inside the firm's existing cloud account, so prompts, documents and model responses are processed within the firm's own environment and under its own access controls rather than on a shared multi-tenant backend.

On top of that runtime, PromptLocker adds an append-only audit log. Every query, model call, document access and returned response is timestamped, attributed to a user and linked to a matter, which makes it possible to pull a compliance report for any date range without reconstructing history by hand. A leader portal gives owners and managing partners a firm-wide view of AI activity, and the audit trail stays in the customer's account rather than with the vendor.

The compliance side is deliberately vertical-specific: onboarding is designed to produce the documentation a given practice actually needs, such as WISP addenda, business associate agreements, ABA Opinion 512 summaries or Reg S-P governance policies. The platform is positioned as an early-access offering for regulated professional firms rather than a general-purpose developer framework, and it does not publish list pricing — access is arranged through a direct conversation about the firm's AI exposure.

**Pricing & Plans:** PromptLocker does not publish list pricing. The site describes an early-access program in which interested firms request access and have a direct conversation about their current AI exposure and the governance work required. Treat any pricing as custom and confirmed during that conversation.

- **Runs inside your own cloud account:** The governance layer deploys in the firm's existing cloud account, so client files, patient records and financial data are processed within the firm's own environment and access controls.
- **Append-only audit log:** Every query, model call, document access and response is timestamped, user-attributed and matter-linked, making firm-wide AI activity reconstructable and reportable.
- **Compliance documentation at onboarding:** Onboarding is built to deliver the artefacts a specific regulated vertical needs, such as WISP addenda, BAAs, ABA Opinion 512 summaries and Reg S-P governance policies.
- **Leader portal:** Owners and managing partners get a web dashboard showing every AI interaction across the firm, with full session logs exportable for any date range.
- **Sanctioned alternative to shadow AI:** Rather than banning consumer AI tools, PromptLocker gives staff a governed tool that works with the right documents already in place.

**Strengths:** Deploys in the customer's own cloud account, so client data does not leave the firm's network; Purpose-built for regulated verticals rather than a generic LLM tool; Immutable, matter-linked audit log supports compliance reporting on demand; Onboarding oriented around concrete compliance artefacts instead of roadmap promises

**Limitations:** No published pricing; you must request access and negotiate; Early-access stage, so features and terms may still change; Focused on regulated professional services, which makes it a poor fit for casual or hobbyist users
