## 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

## Klai

KLAI started life at klai.me and now lives on the Fellow Progress platform, which describes itself as support for people doing difficult things. The premise is simple: instead of browsing a static library of meditation recordings, you tell KLAI briefly what is happening for you — pressure at work, a conversation you are dreading, an urge, self-doubt, an overflowing to-do list — and the product shapes a short guided audio practice around your own words. Daytime sessions run about seven minutes and live in a dedicated KLAI Day area, while a separate KLAI Sleep experience is designed for winding down at night.

The sessions are not one-off one-liners. KLAI builds on what you share over time: you can continue a saved daytime practice when you want to revisit a subject, and the system can use a summary of your previous session as a starting point for the next one. The site offers a set of sample sessions across themes such as work and pressure, people and conversations, habits and urges, confidence, creative block, and everyday overwhelm, free to listen to without an account. The approach and tone were shaped by founder Richard Buchanan, a practising cognitive hypnotherapist, who built the product out of a desire for something more responsive than a fixed recording library.

On pricing, daytime practice is included in a free one-week trial subject to a daily limit, and full membership is £9.99 per month covering both Day and Sleep. KLAI is explicitly positioned as a self-guided wellbeing product rather than therapy: it does not diagnose or guarantee outcomes, and the research the site references concerns guided imagery, body awareness and reappraisal approaches in general rather than proven results for KLAI itself. Treat it as a low-friction daily reset tool you listen to with headphones.

**Pricing & Plans:** KLAI offers a free one-week trial that includes daytime practice (subject to a daily session limit), with several sample sessions free to play without sign-up. Full membership is listed at £9.99 per month and includes both KLAI Day and KLAI Sleep. It is operated as part of the Fellow Progress platform.

- **Seven-minute daytime practices:** Answer a short prompt about what is on your mind and receive a seven-minute daytime audio practice written around your own words.
- **Separate sleep experience:** A dedicated sleep experience where you share what is keeping you awake and settle into guidance that fades into quiet.
- **Continuing, evolving sessions:** Return to a saved daytime practice on the same subject, and let a summary of your last session shape the next one.
- **Free samples, no sign-up:** Sample sessions are free to listen to with no sign-up, so you can hear the format before starting a trial.
- **Built by a cognitive hypnotherapist:** The practice set, questions and tone were designed by a practising cognitive hypnotherapist.

**Strengths:** Sessions are generated from your own words rather than picked from a fixed library; Short seven-minute daytime format that is easy to fit into a break; Separate sleep experience for winding down at night; Sample sessions are free to hear with no account required

**Limitations:** Full access requires a paid monthly membership after the trial week; Positioned as wellbeing support, not therapy, and makes no clinical claims; Daytime sessions during the free week are capped by a daily limit; Requires headphones for the intended experience
