## 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

## Kumo Study

Kumo Study is a Chrome extension designed around the study habits of people with ADHD. Instead of stacking separate apps for planning, timing, and distraction blocking, it puts a weekly planner, a customizable interval timer, a site blocker, and a research bookmark manager into a single browser toolbar surface. The result is one place to see what needs doing, start a focused session, and keep tempting sites out of reach.

Progress tracking and gamification are central to the design. Users earn points and rewards for completing tasks and routines, can interact with friends, and can watch goals accumulate over time. The bookmark area is built for students who write papers: quotes and citations go into custom folders with notes and drafts attached, and everything stays searchable by tag so research does not get lost.

Kumo also supports collaboration, which is unusual for a study tool. A mentor, occupational therapist, study buddy, or family member can join through a collaborator dashboard, add tasks, help shape routines, and send incentives. The free plan covers core planning with 30 bookmarks and 3 blocked sites plus a 15-day trial of Unlimited Kumo, while Kumo Unlimited removes the caps and unlocks collaborators and sensory profile insight for $9.99 per month. Schools and teams can request a custom Business package that includes student performance monitoring and training.

**Pricing & Plans:** Kumo Study is freemium. The free plan includes a 15-day Unlimited trial, a planner, 30 bookmarks, 3 blocked sites, the study timer, and progress tracking. Kumo Unlimited is listed at $9.99 per month (with annual billing available), adding unlimited bookmarks and blocked sites, collaborators, and sensory profile insight. A Business tier is quoted on request.

- **ADHD-friendly planner:** Plan the week, set daily routines, and track progress so important tasks stop slipping through the cracks.
- **Customizable study timer:** Break study sessions into manageable intervals to prevent burnout and protect concentration.
- **Site blocker:** Restrict distracting websites during study or research sessions so focus is not interrupted.
- **Research bookmarks:** Store quotes and citations in custom folders, add notes and drafts, and retrieve them by search or tag.
- **Collaborator dashboard:** Invite a mentor, therapist, or family member to add tasks, adjust routines, and send incentives.

**Strengths:** Purpose-built for ADHD study patterns instead of being a generic task app; Combines planning, timers, blocking, and citation bookmarks in one extension; Collaborator dashboard lets mentors or therapists support progress directly; Generous free plan with a 15-day unlimited trial

**Limitations:** Requires installing a Chrome extension rather than working as a standalone web app; Advanced collaboration and unlimited usage sit behind the paid tier; The ADHD-specific framing is excellent for its audience but narrows its appeal for general study users
