## 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

## TextSynth

TextSynth is an inference platform that has been running since 2020 and was among the first services to expose the GPT-2 language model to the public. Today it bundles several families of open models behind a single REST API and an accompanying web playground: large language models such as Mistral and Llama, Stable Diffusion for text-to-image generation, and Whisper for speech-to-text, alongside speech generation. The company says all servers are located in France.

What distinguishes the service is its inference layer. Rather than relying on standard frameworks, TextSynth maintains custom inference code designed to deliver faster inference on commonly available GPUs and CPUs, which it says translates into lower cost per request. This makes it attractive for developers who want broad model coverage without provisioning or tuning their own serving infrastructure, and for teams that prefer an API-first workflow.

The platform supports typical generation and understanding tasks — text completion, question answering, classification, chat, translation, image generation, speech generation and audio transcription. Usage starts free with rate limits, and users who need unrestricted throughput pay a small amount per request. Teams needing bespoke support can contact the company directly.

**Pricing & Plans:** Freemium. The basic service is free with rate limits; users who want no limitation pay a small per-request fee according to the published pricing page. Custom support is available on request.

- **Multi-modal model access:** One API covers language models like Mistral and Llama, Stable Diffusion image generation, Whisper speech-to-text and text-to-speech.
- **Optimised inference engine:** TextSynth uses its own inference code rather than off-the-shelf stacks to run faster on standard GPUs and CPUs, aiming to reduce cost per request.
- **Free playground:** A browser playground lets you try each model, tweak parameters and evaluate output quality before writing any integration code.
- **Simple REST integration:** Everything is exposed over HTTP, so it can be wired into existing apps, scripts or internal tools without a heavy SDK.
- **European hosting:** All servers are located in France, which matters for teams with data-residency or latency considerations in the EU.

**Strengths:** Broad model coverage — LLMs, diffusion image models, Whisper and speech synthesis — behind one API; Custom inference code tuned for speed on standard GPUs and CPUs helps control per-request cost; Free, rate-limited tier makes it easy to evaluate the platform before committing; Browser playground lets you test prompts and parameters without writing code

**Limitations:** Free tier is rate limited, so production workloads generally require paid usage; Documentation and tooling are comparatively lean next to large commercial model providers; Model catalogue focuses on open-weight models, so exclusive frontier models are not available
