## OpenAI Platform

While ChatGPT serves end users, openai.com and the OpenAI Developer Platform (developers.openai.com) provide the foundational API, SDKs, and enterprise infrastructure powering thousands of production AI applications worldwide. In late 2026, OpenAI's API catalog is anchored by the GPT-6 and GPT-6.1 model suite—all featuring a 1.05-million-token context window and up to 128K output tokens. The lineup spans GPT-6 Astra for frontier reasoning and mission-critical research, GPT-6.1 Sol for near-Astra intelligence at one-fifth the price, GPT-6.1 Terra for fast visual reasoning and computer use, and GPT-6 Luna for ultra-high-volume, low-latency tasks, alongside specialized models like `gpt-5.3-codex` and `gpt-6-astra-law`.

The OpenAI Platform has evolved well beyond basic chat completion endpoints. Through the unified `v1/responses` API, developers can orchestrate stateful multi-step agents equipped with built-in server-side tools—including live web search, vector file search, code interpreter sandboxes, and GUI computer use—without stitching together external orchestration frameworks. Every flagship model supports configurable reasoning effort (`none`, `low`, `medium`, `high`, `xhigh`, and `max`), strict JSON schema Structured Outputs, and multimodal image/audio inputs, while `gpt-live-1` powers per-second billed speech-to-speech voice agents.

OpenAI bills API usage on a transparent consumption model scaled across usage tiers (Build, Launch, and Grow, scaling up to 40M+ tokens per minute). In 2026, aggressive price cuts on the 6.x generation dropped entry-level intelligence on GPT-6 Luna to $0.10 per million input tokens and $0.50 per million output tokens, while GPT-6.1 Sol runs at $2/$10 and flagship GPT-6 Astra sits at $10/$50. Engineering teams can cut spend by 90% on repeated context using automatic Prompt Caching, save 50% on asynchronous workloads via the Batch API, and enforce regional data residency with a 10% compliance uplift.

**Pricing & Plans:** Usage-based pay-per-token API billing: GPT-6 Astra at $10/1M input and $50/1M output tokens; GPT-6.1 Sol at $2/1M input and $10/1M output; GPT-6.1 Terra at $1/1M input and $5/1M output; GPT-6 Luna at $0.10/1M input and $0.50/1M output; GPT-Live-1 voice at $0.05/minute; 90% discount on cached inputs and 50% off via Batch API.

- **GPT-6 & GPT-6.1 Model Lineup with 1.05M Context:** Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
- **Configurable Reasoning Effort Controls:** Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
- **Responses API & Native Computer Use Tools:** Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
- **GPT-Live-1 Realtime Voice API:** Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.
- **90% Prompt Caching Discount & Batch API:** Cached input tokens bill at just 10% of standard input rates, while asynchronous 24-hour Batch API jobs cut both input and output token costs by 50%.

**Strengths:** 100-fold cost flexibility from GPT-6 Luna ($0.10/$0.50 per 1M tokens) up to frontier GPT-6 Astra ($10/$50 per 1M tokens); Unified 1.05M-token context window and 128K output limit across the entire flagship GPT-6 and GPT-6.1 family; 90% discount on cached input tokens and 50% Batch API discount dramatically reduce production inference bills; Industry-standard SDKs, Structured Outputs, and built-in Responses API tools minimize boilerplate agent code

**Limitations:** Long-context requests exceeding the standard window threshold trigger roughly 2x higher per-token billing rates; Flagship GPT-6 Astra ($10 input / $50 output per 1M tokens) is significantly more expensive than Claude Opus 5.5 ($4/$20) and Grok 4.7 ($2/$6); Regional data residency endpoints incur a 10% price uplift on models released after March 2026

## SimFin

SimFin positions itself as a data-first alternative to traditional stock research portals. Instead of opinion-driven ratings, it gives you 80+ screening indicators, custom filter logic and 20+ years of chart and fundamental history across roughly 5,000 listed companies. Findings can be saved as studies and strategies, shared with other members, or exported for further work.

The backtesting layer lets you test single names or multi-condition portfolio rules against decades of history, with adjustable rebalancing intervals and benchmark comparisons. A high-speed credit system meters intensive screening and backtest runs, with monthly budgets that scale by plan.

For programmatic users, SimFin exposes the same dataset through a Python API, an Excel plugin, a JSON web API and bulk CSV downloads. Data is aggregated in-house from company filings and passed through a QA step before publication, so each figure can be traced back to the source statement.

**Pricing & Plans:** Freemium with four tiers. FREE costs $0 and includes the screener, 5 years of history and light API access. START is about $15/month, BASIC about $35/month and PRO about $71/month when billed annually, unlocking longer history, more high-speed credits and higher call-rate limits. A 50% student discount applies to BASIC, and Enterprise pricing is quoted on request.

- **Fundamental stock screener:** Filter thousands of stocks with 80+ built-in indicators and unlimited custom conditions, then visualize the matches as line charts, scatter plots or distribution plots.
- **Strategy backtesting:** Test single stocks or weighted multi-criteria portfolios over 20+ years of history, with weekly to yearly rebalancing and sector benchmark comparisons.
- **Data API and bulk export:** Pull the same dataset through a Python package, Excel plugin, JSON web API or CSV bulk download, with tiered call-rate limits from 2 to 20 requests per second.
- **High-speed credit system:** Monthly credit budgets from 500 to 30,000 let heavy users run intensive screens and backtests without throttling the interactive app.
- **Shareable studies and portfolios:** Save private portfolios, publish studies and strategies, and let other members copy, comment on and rate your setups.

**Strengths:** Transparent, traceable fundamental data built in-house rather than scraped from third parties; Free tier is genuinely usable for screening and light API work; Comparatively low subscription cost versus institutional data terminals; Strong developer ergonomics through Python, Excel and JSON endpoints

**Limitations:** European market coverage historically lags US coverage; Heavy backtesting and high-speed screening are metered by credits; Interface density is high and can overwhelm beginners; No broker execution or live-trading features
