## 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

## Mathos AI (formerly MathGPT)

Mathos AI, previously published under the MathGPT name, is a Chrome extension that overlays an AI math helper onto normal browsing. It is aimed at students from middle school through university, as well as teachers and lifelong learners, and it positions itself as more than a calculator: the extension combines a solver, a personal tutor, and a set of dedicated calculator tools. The publisher reports a user base of over two million students across more than 200 countries for the broader Mathos product.

The workflow is built around convenience. You can upload and edit a homework PDF, snap a photo of a problem, type it out, draw it by hand, or dictate it with your voice, and the extension accepts all of those inputs. Solutions come back as detailed steps, and because the tutor recognises drawings and speech, you are not restricted to typed equations. Multi-device sync means a problem started on a phone can be continued on a laptop.

Supporting the solver is a graphing calculator for interactive plotting and a broad collection of specialised calculators covering everything from fractions and square roots to limits, integrals, derivatives, and scientific notation. The extension is published by the team behind mathos.ai, with support contact at mathgptpro.com — a remnant of the earlier branding.

**Pricing & Plans:** Freemium. Adding the Chrome extension is free, and the product offers free core features with paid plans for advanced or high-volume use. Check the developer's website for current tiers.

- **AI math problem solver:** Get instant, step-by-step solutions for problems spanning basic algebra, geometry, and advanced calculus, with explanations that build understanding.
- **PDF homework helper:** Upload a homework PDF and solve problems straight from the document while annotating it, taking notes, and interacting as you work.
- **Personal AI tutor:** Receive tailored tutoring that recognises your voice and drawings and adapts its pacing and explanations to how you learn.
- **Graphing calculator:** Plot equations and functions interactively to visualise relationships instead of only computing numbers.
- **Calculator collection:** Specialised calculators cover fractions, algebra, graphing, integrals, derivatives, quadratics, square roots, limits, factoring, and scientific notation.

**Strengths:** Accepts many input styles: typed text, photos, drawings, voice, and PDF uploads; Step-by-step explanations plus voice and drawing recognition for a tutor-like experience; Ships with a graphing calculator and many topic-specific calculators; Publisher states it is trusted by over two million students worldwide

**Limitations:** AI reasoning can still produce incorrect steps, so answers deserve verification; Advanced features and higher usage limits require a paid plan; The MathGPT-to-Mathos AI rebrand can be confusing when following older links or tutorials
