6 AI Services You Can Use Free or Almost Free Right Now

Black Forest Labs has opened FLUX 3 Video, a multimodal model for video generation that works with text and images, creates videos up to 20 seconds, and produces audio with video. It supports text-to-video, image-to-video, keyframe work, native audio, multi-language speech, and lip-sync, with HD output and Full HD upscaling, and is marked 'free to try this week' on the official site. Manus offers free access to its AI agent models Manus 1.6 and Manus 1.6 Lite until August 25, 2026, 23:59 SGT, and also has a permanent free plan with 1000 starter credits and 300 daily credits, but free accounts are limited to Manus 1.6 Lite for Agent Mode. Postman's Agent Mode is available on the free plan with 50 AI credits per month, and a 30-day Enterprise Trial without a credit card includes AI-powered workflows and access to a set of GPT and Claude models. GoRouter provides an OpenAI-compatible API endpoint (https://gorouter.app/v1/chat/completions) listing claude-opus-4-8, claude-opus-4-8-thinking, claude-opus-5, and claude-opus-5-thinking at $0.2-$0.3 per request, but there is no public documentation to confirm model provenance or pricing, so it should be treated as a third-party API router. Atomesus offers a large starter API balance after registration and applying referral code ATOMESUS, with an OpenAI-compatible endpoint at https://api.atomesus.com/v1/chat/completions, plus file analysis and image generation. Deepgram gives new accounts $200 in free credit with no expiration for Pay As You Go, usable for Speech-to-Text (including the Nova-3 model), Text-to-Speech, Voice Agent API, realtime transcription, and voice agent development, without requiring a bank card. All checks were done on August 12, 2026, and users are advised to verify current terms, limits, and model availability before use.
