Google AI Studio Gemini Free API Guide: 1,500 RPD, 1M Context, and Setup Guide
In September 2026, Google AI Studio continues to offer the industry's most generous zero-card free tier: 1,500 daily requests (RPD), 15 RPM, 1M TPM, and a 1M token context window for Gemini 2.5/1.5 Flash with native Search Grounding. The official OpenAI-compatible endpoint drops into any third-party client. However, free tier interaction data is logged for Google model training; proprietary commercial assets must remain strictly excluded.

OpenCode unlocks Meta Muse Spark 1.3 for free: 1.05M context, 206 tok/s speed, and safety boundaries
On September 4, 2026, open-source coding agent OpenCode launched free access to Meta Muse Spark 1.3 (Contributor Tier). Requiring zero credit card info, developers can authenticate via GitHub to access a 1.05M token context window at 206.3 tok/s, outperforming Claude Opus 5 and GPT-5.6 Sol with 75.4 on DeepSWE v1.1. Under the Contributor data agreement, Meta retains prompts and code diffs for model training; proprietary commercial assets must remain strictly excluded.

AMD opens free AI model APIs on Radeon Cloud: 1M-token DeepSeek, $10 daily credits, and zero-proxy access
In late August and early September 2026, AMD launched Token Factory on Radeon Cloud, distributing Public Free Model APIs to registered developers. The launch lineup features DeepSeek-V4-Flash with a massive 1,048,576-token context window (1M tokens), Qwen3.8-Flash-Next (256K), and MiniCPM. AMD established dedicated China routing at developer.amd.com.cn (zero-proxy access), dual OpenAI/Anthropic protocol compatibility, and default daily allowances of approximately $10 USD per account (governed by a 30 RPM key limit and 20 RPM gateway). This represents an aggressive play by AMD to capture software developer mindshare with subsidized compute.

ZCode is giving away 100M GLM-5.3 tokens: how to claim one of 50,000 slots
ZCode is promoting a limited GLM-5.3 token offer for new users: 100 million tokens in total, 50,000 slots, running from August 21 at 09:00 to August 23 at 18:00 Pacific Time on a first-come basis. That averages about 2,000 tokens per slot, not 100 million per person. The public homepage does not show every campaign rule, so eligibility, crediting and stacking limits must be checked after signing in.
For new users who want to try GLM-5.3, ZCode's coding agent, repository tasks and multi-agent workflows at low cost
Ox Alpha's mask is slipping: is OpenRouter's free 1M multimodal model GLM-5.3 Flash?
Ox Alpha has not received an official identity confirmation, but the available black-box evidence strongly points to the GLM-5.3 family: tokenizer counts differ by a constant 75 tokens across multiple texts, while error strings and temperature-zero output quirks also match closely. OpenRouter currently lists it as free with text, image and video input and a 1M context; free does not mean unlimited or production-safe.
For readers trying anonymous models, OpenRouter, GLM, OpenCode and coding or browser agents, especially anyone weighing free-model privacy and limits
