OpenAI GPT models

AI Spend Doctor — Analyzes exported Claude and OpenAI API usage or cost files offline to show spend spikes, cache and batch share, and model price scenarios.

Prompt Catalog — Provides a subscription library of AI image and video transformation prompts and theme assets, plus embeddable website widgets for showcasing them.

How do you know which customer… — Proxies OpenAI API calls and reports token cost grouped by customer, feature or model.

AegisFlow — Sits between an app and LLM APIs, masks PII in prompts before they are sent, restores the real values in responses, and writes a signed audit log.

callm — Wraps native LLM SDK call functions with retries, caching, fallbacks, cost budgets, PII masking and output validation via a Python decorator.

Astra Preflight — Checks a local API request JSON payload for known migration problems before it is sent.

apinae migration packs — Provides migration guides and codemods that port code from the OpenAI Assistants API to the Responses API and from the Bing Webmaster SOAP/POX API to REST.

Auscope — Audits LLM responses in the background using multiple models from different providers and returns a verified, uncertain, or unreliable verdict.

Assistants Rescue — Exports OpenAI Assistants data to a JSON backup and generates Responses API code to replace each assistant.

Fixing the "garbage in, garbage… — Rewrites a developer's raw prompt into model-specific structured syntax via a Chrome side panel hotkey, injecting cached project context automatically.

CachePilot — Caches LLM responses keyed by system prompt hash and serves repeat matches without calling the model provider.

Is anyone else getting surprise… — Tracks OpenAI and Claude API spending by model and user and alerts when a budget is about to be exceeded.

Built something that stops AI… — Estimates the cost of LLM API calls before they are sent and holds calls above a threshold for approval.

AI Architecture Scanner — Scans pull requests for AI API usage and posts a comment flagging costly model choices, duplicate AI calls, and missing retry logic.

Arol — Scans a code repository and flags references to AI models or APIs that are deprecated or scheduled for retirement, along with their retirement dates.

I kept hitting free-tier rate… — Routes OpenAI-compatible chat requests across several free LLM provider tiers, falling over to the next model when one hits its rate limit.

Rynler — Provides a prepaid, OpenAI-compatible text inference API for adding LLM steps to scripts and automation workflows.

Gonka — Routes LLM API calls to independent GPU hosts over a blockchain-tracked network, with spot checks to catch hosts that serve cheaper models.

RelayRouter — Routes requests from one OpenAI-compatible endpoint and API key to multiple AI model providers for text, image, audio, and video models.

Lattice — Serves two small open language models through a free web chat and a free OpenAI-compatible API.

ramdeck-core — Pools RAM and VRAM across networked machines to run a large language model behind an OpenAI-compatible API.

amble — Turns a sentence describing the user's day into a structured schedule using a small on-device language model.

Jeff Pro — Acts as a domain-specific AI co-founder that advises on go-to-market, positioning, validation, financial planning and investor simulation for startups.

TESRAC — Generates multi-agent deep research reports on a query and stores them in a public, searchable index for reuse.

TUFF — Runs large mixture-of-experts language models locally on a Mac by keeping shared weights in RAM and streaming experts from SSD through a bounded cache.

EidosStack AI Gateway — Routes API requests to many LLM providers through one OpenAI-compatible endpoint and displays live per-token pricing before requests are sent.

DocStash — Hosts AI-generated documents and static web apps at stable private URLs that can be published with one click.

GPTVoice — Relays a ChatGPT live voice conversation into a Discord voice channel using the user's normal ChatGPT web session.

Aegis — Wraps the Claude Agent SDK in a multi-tenant API and admin dashboard that lets a team share one Claude subscription with per-user keys, rate limits and cost caps.

OmniGPT Gateway — Exposes a local OpenAI-compatible chat completions endpoint that relays prompts through browser automation to the ChatGPT web interface.
