## 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

## Mezzi

Mezzi is an AI-driven wealth management platform that aims to make institutional-grade financial advice accessible to ordinary investors. It is an SEC-registered investment adviser, which it uses to distinguish itself from both traditional human advisers and generic AI chatbots. The core idea is breadth: rather than limiting advice to the assets you hand over, Mezzi looks across all your connected accounts, assets, and liabilities to build a complete picture.

From that picture, Mezzi generates guidance across three main areas. On taxes, it flags opportunities such as tax-loss harvesting and Roth conversions, and estimates the dollar impact of each. On retirement, it models how your goals and contributions map to outcomes, including tools like a 401(k) fee analyzer to spot costly funds and strategies for accessing retirement funds early without penalties. On investments, it builds and monitors a portfolio that stays within your stated risk tolerance and diversification preferences.

Interaction is chat-first. Mezzi presents itself as an always-available adviser with no scheduling and no net-worth-based prioritization, letting you ask questions and get recommendations in context. The site is candid about limitations too: it relies on third-party APIs to pull data from financial institutions, so it can only capture opportunities from the information it is given, and it states plainly that investing involves risk, including possible loss of principal. Registration with the SEC does not imply a certain level of skill or training.

**Pricing & Plans:** Mezzi offers a membership model. The site references an annual subscription fee — around $399 per year — in its fee-comparison illustrations, plus a free consultation call option. Compared with a typical 1%-of-assets adviser fee, the subscription framing is a central part of its pitch; check the pricing page for current plan details.

- **Whole-portfolio analysis:** Analyzes your full financial picture across every linked account, including assets and liabilities, instead of only the assets transferred to an adviser.
- **AI tax-loss harvesting and tax strategy:** Identifies opportunities like tax-loss harvesting and Roth conversions and surfaces estimated savings from your actual holdings.
- **Retirement and asset allocation planning:** Builds and monitors a portfolio aligned to your risk tolerance and retirement goals, with diversification guidance.
- **On-demand advice chat:** Chat with an always-available AI adviser about money questions — big or small — and get answers grounded in your accounts rather than generic advice.
- **Fiduciary, SEC-registered guidance:** As an SEC-registered investment adviser, Mezzi frames its guidance around a fiduciary standard rather than product sales.

**Strengths:** Analyzes accounts across institutions rather than only transferred assets; Combines tax, retirement, and investment guidance in one place; SEC-registered adviser with a fiduciary framing; Always-available chat with no scheduling or wait times

**Limitations:** It is a US SEC-registered adviser, so its advice is aimed at US investors and their account types; Its recommendations rely on third-party data feeds, which can be delayed or incomplete; Mezzi works best when you connect all accounts, so partial setup limits the value
