## 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

## Rezzy

Rezzy positions itself as a resume builder made for software engineers rather than a generic template tool. Instead of swapping keywords, its multi-agent workflow makes real tailoring decisions: it chooses which experience and projects stay or get cut, how sections are ordered, how the page is structured for ATS parsing, and how each bullet is phrased for signal density. Output is generated in LaTeX underneath, so documents stay clean, consistent, and parseable by applicant tracking systems.

Beyond generation, Rezzy includes AI-powered resume scoring that rates ATS compatibility and best practices, then gives actionable feedback on formatting, keywords, structure, and job-specific requirements. Company research capabilities help align a resume to a target employer, and a chat-based flow lets users iteratively shape the result rather than accept a static document.

Because its audience is developers, Rezzy exposes an API and an MCP server that plug into ChatGPT, Claude, Cursor, and Codex-style clients, so users can generate tailored resumes from scripts or AI agents. A free tier covers a limited number of generations with unlimited scoring, while a low-cost Pro plan unlocks unlimited resume and cover letter generations and a monthly API credit allowance.

**Pricing & Plans:** Freemium. Free plan ($0) includes 4 resume/cover letter generations, 25 API credits, unlimited scoring and feedback, and full editor/exports. Pro is $14/month after a 7-day free trial and adds unlimited generations, the Tailr interactive chat, and 1,000 API credits per month.

- **Role-specific tailoring agents:** Multi-agent workflows decide what content stays or gets cut, reorder sections, restructure the layout for ATS parsing, and rewrite bullets for stronger signal.
- **ATS-compliant LaTeX output:** Documents render in LaTeX under the hood, producing clean, consistent, machine-parseable files plus PDF and LaTeX exports.
- **AI resume scoring:** Instant scoring rates ATS compatibility and best practices, with detailed feedback on formatting, keywords, content structure, and job requirements.
- **Company research for applications:** Targeted research capabilities help align resume and cover letter content with a specific employer and role.
- **API and MCP server:** Generate API keys and connect Rezzy to ChatGPT, Claude, Cursor, or Codex clients so resumes can be tailored from scripts and AI agents.

**Strengths:** Tailoring goes beyond keyword swaps by restructuring and rewording content; LaTeX-based output is clean and ATS-friendly; Free tier includes unlimited scoring and full editor access; Strong developer story with API and MCP integration

**Limitations:** Explicitly optimized for software engineers, so fit is weaker for other fields; Free plan caps generations at four before requiring Pro
