schema_version: 1 title: Free hosted model inference providers and routers as_of: "2026-08-21" checked_at: "2026-08-21T23:37:26-05:00" timezone: America/Chicago snapshot_counts: current_offer_records: 76 headline_ongoing_or_recurring_records: 38 conditional_delivery_current_records: 7 finite_trial_or_promotion_records: 31 conditional_or_needs_verification_records: 20 historical_or_excluded_records: 37 note: Current offers include trials and conditional delivery models; filter free_kind and headline_ongoing_free rather than treating 76 as a count of permanent free tiers. scope: completeness: Best-effort exhaustive public-web audit, not a guarantee that every regional, private-beta, dashboard-only, or newly launched service has been found. primary_subject: Hosted foundation-model inference, routers, and serverless model-deployment platforms. modalities: [text_generation, embeddings, reranking, image, audio, speech, safety, custom_model_deployments] included: - Remotely callable hosted model inference with an API. - Ongoing free tiers, recurring credits, experimental access, and model-specific zero-price routes. - Time-limited trials and promotions when clearly labeled as such. excluded_from_current: - Open weights that require self-hosting. - Web chat without a remotely callable inference API. - A free gateway whose upstream model inference is still billed, unless it also has named zero-price models. - Offers found only in stale or third-party pages without current first-party confirmation. verification_levels: live_catalog: An official models endpoint was queried without credentials; this does not prove an authenticated generation succeeded. live_call: A credential-free inference call succeeded; this still does not prove authenticated-account behavior or billing. official_current: Current first-party pricing, documentation, or product pages explicitly support the claim. dashboard_only: The provider says the limit or catalog is visible only after sign-in. conflicting: Current first-party sources disagree; both claims are retained. authenticated_generation_policy: No provider credential was created and no authenticated generation was billed for this audit. A live_catalog label validates published server metadata, not end-to-end callability. important_note: Free catalogs and quotas are volatile. Re-fetch each discovery URL before relying on this snapshot. website_filtering: default_current_list: Read records only from providers. headline_ongoing_free: omitted_or_true: Normal ongoing, recurring, restricted-research, or active experimental offer. conditional: Show with a community-capacity, user-pays, data-use, or sustainability warning. false: One-time trial, application credit, or limited promotion; never label as a permanent free tier. candidate_list: Read conditional_or_needs_verification separately and never merge it into verified counts. unavailable_list: historical_or_excluded contains retired, paid-only, non-API, nonfunctional, and self-hosted-only results. recommended_badges: [free_kind, status, confidence, payment_method_required, geography, modality, verification] discovery_coverage: interpretation: Ecosystem registries are candidate generators, not proof that each upstream provider has a direct free API. openrouter_provider_registry: checked_at: "2026-08-21" discovery_url: https://openrouter.ai/api/v1/providers live_provider_count: 104 caveat: The live API includes a synthetic-looking fake-provider entry; it is retained for exact snapshot fidelity and is not treated as a real provider candidate. provider_slugs: - ai21 - aion-labs - akashml - alibaba - amazon-bedrock - amazon-nova - ambient - anthropic - arcee-ai - atlas-cloud - avian - azure - baidu - baseten - black-forest-labs - cerebras - chutes - cirrascale - clarifai - claude-on-aws - cloudflare - cohere - coreweave - crucible - crusoe - darkbloom - databricks - decart - deepgram - deepinfra - deepseek - dekallm - digitalocean - fake-provider - featherless - fireworks - fish-audio - friendli - gmicloud - google-ai-studio - google-vertex - groq - heygen - inception - inceptron - inferact-vllm - inference-net - infermatic - inflection - io-net - ionstream - krea - liquid - makora - mancer - mara - meta - minimax - mistral - modal - modelrun - modular - moonshotai - morph - ncompass - nebius - nex-agi - nextbit - novita - nvidia - open-inference - openai - parasail - perceptron - perplexity - phala - poolside - quiver - recraft - reka - relace - runpod - runway - sail-research - sakana - sambanova - seed - siliconflow - sourceful - stealth - stepfun - streamlake - switchpoint - tencent - tenstorrent - thinkingmachines - together - upstage - venice - voyageai - wafer - xai - xiaomi - z-ai huggingface_inference_provider_registry: checked_at: "2026-08-21" discovery_url: https://huggingface.co/docs/inference-providers/main/en/index documented_integration_count: 19 provider_ids: [cerebras, cohere, deepinfra, fal_ai, featherless_ai, fireworks, groq, hf_inference, hyperbolic, novita, nscale, ovhcloud, public_ai, replicate, sambanova, scaleway, together, wavespeedai, zai] other_systematic_sources: - NVIDIA Build/NIM catalog, developer terms, model cards, and partner announcements. - Vercel AI Gateway, OrcaRouter, Kilo, FastRouter, OpenCode Zen, and community-router catalogs. - Official pricing, billing, rate-limit, changelog, status, GitHub, press-release, X/Twitter, and news searches for every named candidate. coverage_note: Every positive record below has provider-specific evidence. High-probability negative results are retained under historical_or_excluded to prevent rediscovery from stale announcements. free_kinds: ongoing_free: Recurring or indefinite no-cost API usage under a quota. rotating_zero_price: Named models cost zero while they remain in a changing catalog. recurring_credit: A monetary allowance that refreshes on a stated schedule. experimental: Free only while a preview or experiment remains active. development_only: Free for prototyping or evaluation, not production use. promotional: A temporary model promotion or expiring allowance. trial: A one-time new-account credit or time window. community_capacity: No-cost inference supplied by volunteer or community-operated capacity with no guaranteed throughput. user_pays: The developer pays nothing because each end user authenticates and consumes that user's own allowance. providers: -
