## 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

## Foundry

Automating real web workflows is hard because the web itself is unstable. Sites change layout, block bots, throttle requests, and return different content depending on region or session — which means agent teams spend more time fighting infrastructure noise than improving their models. Foundry, built by a Y Combinator-backed team, attacks this problem directly by delivering pixel-perfect, reproducible browser environments. The platform's simulation layer generates deterministic web snapshots, so the same task produces the same environment every run, with no drift, no noise, and no rate limiting standing between an agent and a clean signal.

The second pillar is evaluation. Rather than returning a vague pass/fail score, Foundry tracks every agent action and classifies it — silent click failures, layout shifts, misfires and other error classes are surfaced explicitly. Teams get full state snapshots, state mutations and event logs after each trajectory, which they can diff against ground truth with their own heuristics. This makes it far easier to know whether a regression came from the model, the page, or the environment.

The third pillar is data and reinforcement learning. Foundry provides expert human annotators who build custom, long-horizon datasets for supervised fine-tuning of browser agents on real enterprise platforms, plus an RL environment (accessed through a Python SDK) where teams can safely sample and evaluate unlimited trajectories. Access is currently gated behind a private beta application, and the company also publishes benchmark leaderboard results for browser intelligence.

**Pricing & Plans:** Pricing is not published publicly. Foundry currently operates a gated private beta with an "Apply for Access" flow, and commercial terms are discussed directly with the team.

- **Deterministic browser simulation:** Pixel-perfect, reproducible browser environments that eliminate web drift, noise, and rate limits so agent runs are comparable over time.
- **Structured agent evaluation:** Every action is tracked, classified, and tagged — click failures, layout shifts, and misfires are surfaced rather than silently swallowed.
- **Expert-annotated datasets:** Human annotators build custom, long-horizon training data for supervised fine-tuning of browser agents on real enterprise platforms.
- **Unlimited RL trajectories:** Safely sample and evaluate large numbers of trajectories to train browser agents at scale, without running into anti-bot constraints.
- **Python SDK integration:** Plug Foundry into an existing agent workflow with an SDK that exposes task reset, CDP URL, final state, state mutations, and event logs.

**Strengths:** Purpose-built for browser/web agents rather than generic LLM evaluation; Reproducible environments remove a major source of confusing noise in agent benchmarks; Error classification is granular, helping teams attribute failures correctly; Combines simulation, data annotation, and RL in one platform instead of three vendors

**Limitations:** Access is limited to a private beta application, so onboarding is not self-serve; No public pricing, which makes budgeting hard before talking to sales
